[SLUG] Filesystem help for a non-expert
Hello, Is anyone able to recommend some resources (online or print) that might help me understand the Linux filesystem a bit better. I have been through about six books so far and it is still a mystery to me. I've been having trouble with at least two of the hard drives in my server and there seems to be further trouble with the RAID system that is in place. I'd like to be able to run some diagnostic checks and if possible, repair the problematic disks but I'm worried that unmounting the disks will cause the whole system to fail (my previous attempts ended that way). Thank you, Grant Bailey -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] Linux apps and mapped network drives
My Guess would be that the LibreOffice and thunderbird is using a different file browser eg nautilus rather than dolphin. The share that you mapped in Dolphin looks like it is only availible in dolphin. To check this from the command line run mount and look for a smb mount. This command would show you the OS/system level mounts. What I suspect is either dolphin does not create a system mount or it does just in a weird path. * These are some guesses I have made, having not used dolphin nor fedora 17 :-) I don't know offhand a GUI tool to do network system mounts. They can be setup easily using fstab, autofs etc. the trick with samba is if you need authentication AND security... if you do need both have a look at pam_mount. HTH Grant On 21/06/12 19:57, Ben Donohue wrote: Hi all, Just loaded Fedora 17. In the file manager Dolphin, I have mapped a SMB share (to a NAS box) and it works correctly. When saving a file in LibreOffice or saving an attachment in Thunderbird, or some other app, they don't list the network share that has been mapped in Dolphin. Even after a reboot in case it needs it. Seems really weird to me. If I map a drive or network share, you would think it would become available to all applications, like MS Windows does. However I sure as hope not that all applications have to map the drive. So, how does one map a drive in Fedora and make it available to ALL applications when saving files?

Re: [SLUG] Inverting network interfaces
Couple of things here 1 modprobe config file (location depends on distro) Make sure you set the driver to the correct device 2 /etc/sysconfig/network-scripts/ifcfg-* Match the DEVICE= and HWADDR= lines listed in these files with those listed in modprobe config file. My advice would be to do the following 1 remove any driver lines in modprobe files 2 remove all HWADDR and DEVICE lines from the ifcfg files 3 reboot 4 Determine which order the devices are detected first (should be the onboard eth0) 5 Determine what needs to be done from there.

We've installed a router device at one of our customers; it is a Via motherboard and has therefore a Via Rhine network interface on the motherboard (eth0) and a Realtek 8139 network interface on a PCI card. For some reason, the drivers for the two network interfaces seem to spontaneously invert, with the Realtek driver applying itself to the Via port (and usually working OK!) and the Rhine driver to the Realtek port (and sometimes not working - but sometimes working as well). This does not follow any outside action, although the customer has learned that rebooting the system (cleanly) solves any non-working interface issue. Can anyone shed any light on this?

Hello I have some desktop linux machines that have periods of extremely high system time (30-90%) with no obvious cause. The users see it as a hang or a freeze to the point of 10sec for a key press to register. it comes and goes seemingly randomly but only lasts max about 1-2 min. What I'm after is any hints on how to track down whats causing this. Symptoms - load average is low (sub 1) - No process is consuming a lot of cpu (from top) - No swapping is occurring at the time - plenty of free memory - no/low IOwait% - IRQ% is 0 - Still has Idle available - nothing in dmesg Any help or investigation tips would be appreciated Thanks -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Force mounting usb storage read only
Hello All Before I post to the Centos list I was wondering if you all had any ideas. Due to compliance requirements we are looking to be able to force mounting of usb drives to be read only. We originally thought of black listing the usb-storage kernel modules. Although it is very simple to implement, it is probably a bit too restrictive. I am getting confused however what exactly is doing the auto mount for desktop machines and how to introduce different mount options eg ro . I found that Centos 6 has udev, HAL, udisks and gvfs and trying to decipher who does what is a bit daunting. I know that all bets are off for the root user, I am just looking for a solution for average user logging in graphically.

Re: [SLUG] Re: Raspberry Pi
The big thing is that it is essentially a small computer that is good enough to run quake, decodes h.264 etc This means it opens up a whole lot to software/OS tinkers. They are able to create their own devices/projects with limited funds ~$40 and limited electronics knowledge. eg They have been able to get XBMC on it, to create a htpc front end for the cost of raspbery pi, a mini usb charge cable (for power) and an SD card and may be a remote. No fans, spinning disks etc etc. Some people are looking at it as a cheaper, smaller, lower power alternative to a shuttle pc . Think of the posibilities People around the world were begging the developer to release it hence the interest. yes it's early days, but with this much interest it's better to get this out. People don't need a case if they are making their own thing with it. It's not an apple product but no soldering is required.

Re: [SLUG] Value of Red Hat certification ?
Hi There are other certification bodies such as LPI. The course are cheaper and done through tafe I think. You may get more mileage with experience rather than courses. Try to get as much hands on as possible by volunteering, being mentored, talking. Chat to your local friendly sysadmin :-) Having a development background and experience is always a plus. Don't discount it.

Re: [SLUG] Virtualisation and DRBD
It depends on your level of availability. you can achieve 98% percent with Virtualised solutions and live migration or vmotion. This means migrating a functioning virtual server from one physical server to another with no outage. You just need some shared storage that has suitable raid levels and redundant network/fibre cards and switches. We use NFS as our shared storage and find it great. This live migration has the advantage of 1 Migrate virtualised servers away from a physical host that requires maintenance. 2 Utilise both phyiscal servers or keep one in standby. 3 Straight forward recovery. Just boot the virtual machine on a different physical machine. 4 Scalable The only downside is that if there is a hard failure, it is like someone tripped over the power cord. In a lot of scenarios if you decrease your planned outages to 0, this is acceptable. The last 2% will require the biggest effort in designing, implementing, testing, testing and more testing, oh and don't forget the ongoing maintenance and documentation. It really depends on what is acceptable risk, acceptable downtime, acceptable data loss and therefore what you need to protection from. eg Disk failure, network failure, heartbeat failure, hardware failure, power failure, HTH Grant On 25/08/10 12:46, Nigel Allen wrote: Hi All We're investigating both virtualisation of servers and High Availability at the same time. Currently looking at Linux-HA and DRBD (amongst others). The idea of DRBD appeals to both me and the client as it means (or seems to at least) that we could add a third (off-site) machine into the equation for "real" DR. What happens when we then introduce Virtualisation into the equation (currently have 4 x servers running Centos& Windoze Server - looking at virtualising them onto one single box running Centos-5). I suppose the (first) question is: If we run 4 virtualised servers (B, C, D, and E) on our working server "A" (complete with it's own storage), can we also use DRBD to sync the entire box and dice onto server A1 (containing servers B1, C1, D1, and E1) or do we have to sync them all separately? Will this idea even float? Can we achieve seamless failover with this. If not, how would you do it Any input (as ever) gratefully accepted.

Re: [SLUG] MythTV hardware advice sought
I have never used nor affiliated with them but someone pointed me their way when I was thinking about a mythtv box and was worried about months of hardware research/cross checking/pricing etc There is a open platform called Dragon http://mythic.tv/index.php/dragon-v2-0.html and a company in Aus that sell them http://www.better-access.com/index.php?dest=order Grant John Clarke wrote: Greetings Sluggers, I'm planning to build a MythTV box & have come up with what I think is suitable hardware to run it on, but I'm hoping that those of you with MythTV experience will point out anything I've got wrong. The box will be both back and front end and will be in the lounge room in the cabinet with the amps, dvd player, etc, so it'll need to be fairly quiet, especially when idle, but I don't want to hear much when it's running either. It's going to be inside a cabinet so doesn't have to be stunningly beautiful, but I don't want it to look spectacularly ugly either. My budget is $2000. I want HDMI video to the TV (LCD, 1080p), either with audio or with a separate analogue audio cable. I also want digital audio (S/PDIF, preferrably coax) to the amp for better quality stereo or 5.1 audio. I'd also like the option of watching either live TV, recorded programs or ripped DVDs on any other PC on the LAN, at the same time as a different program is being watched on the TV and maybe another is being recorded. I believe that all of the hardware I'm thinking of is supported by Linux and MythTV, and although I don't think the necessary drivers are packaged in any distro yet (I'm thinking of using the latest Mythbuntu, only because everything else is running Ubuntu), I do know where to get them.

We have occasionally wished for a third tuner in the past (not often, there's not that much worth watching on TV), so I may as well have four, just in case :-) Is this hardware powerful enough to do all that I want? Do I need more CPU grunt? More RAM? More hard drives? Bigger PSU? Anything else? The only other thing I can think of is remote control. I'd like to be able to control it from my Logitech Harmnony One remote, at least for the most common tasks, so obviously I'll need some sort of IR receiver. From what I've read, the USB IrDA dongle I have is unlikely to work, so I'll need something else. All I've been able to find are receivers bundled with remote handsets, but I already have half a dozen or so of those gathering dust and don't need to add another one to the collection. Advice and suggestions will be gratefully received.

[SLUG] workspace switcher names not saving
On my Ubuntu 8.10 laptop I can set the names of the 8 workspaces I use by right clicking and selecting preferences. Apparently this is dependent on not having Compiz and among other things the video card driver, in my case Nvidia. The names of the workspaces only appear to last as long as the session does. They survive a suspend and resume ok but logging out and logging back in changes them back to the default of "Workspace 1" "Workspace 2" ... etc. I should point out that it DOES save my preference for the number of workspaces and the number of rows they appear in. For now my workaround is going by memory... ie "Workspace 2" is my web window, workspace 1 is my mail window. Has anyone else had this experience and/or found a workaround? Does it happen in 9.04? Does it happen in Fedora 11? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[LAN/WAN/Internet?] | | [[eth0 x.x.x.x] [ | [ | [[qtap0] 213.133.127.y] [ [physical machine] Firstly... `cat /proc/sys/net/ipv4/ip_forward` should result in '1' being displayed. If not you need to adjust your /etc/sysctl.conf and then reload it with `sysctl -p`. This is the master switch that says your host is actually a router as well. Secondly, and I suppose you've already done this, check that you can ping the virtual from the host and that you can ping the host from the virtual. If not, get that working first. Next if the outside world has an appropriate route to your subnet (it appears to) that's great. If not you'll have to NAT it's traffic coming out of eth0 with something like `iptables -t nat -A POSTROUTING -s 213.133.127.0/29 -j MASQUERADE` which will translate everything to your x.x.x.x address somewhat defeat the purpose of the /29 net but it'll work. Next failing that you'll have to supply more information like what x.x.x.x is, your routing table, your iptables setup. `iptables -t filter -L -n -v` and `iptables -t nat -L -n -v` and some examples of the output of tcpdump on eth0 and qtap0 concurrently. EG `tcpdump -n -i eth0 icmp` in one terminal and `tcpdump -n -i qtap0 icmp` in another terminal.

IANAL, but I do hunt them for sport :-) ... so if you're still reading, this is not legal advice, only opinion. I've dealt with exactly this type of claim before. Your employer already has these rights in all Australian jurisdictions for anything you produce on company time or using company equipment/resources, under the work-for-hire doctrine (assuming here that you are an employee). However, outside work, and using your own equipment/resources, they have no such claim. They don't need you to sign such a clause to enforce work-for-hire rights if that's what they're seeking. If they're asking for blanket rights to things you do produce outside work, find the consideration (legal term meaning: the additional benefit they're giving you for you signing away these rights) in the rest of the agreement, and ask yourself if that's reasonable. Consideration can't be something you already have/have rights to (e.g. your existing job or benefits) ... it needs to be a new benefit. If there's no consideration, the clause won't stand, even if you do sign it, as it violates a fundamental tenet of contract law. However, it may take legal action to force this point if push comes to shove. You could ask your employer to clarify the clause to emphasise they're simply stating their work-for-hire rights, and have them adjust the text accordingly ... that might make it clear exactly what it is they're after, and inform your options accordingly.

Re: [SLUG] linux firewall/vpn devices wanted (and found)
Argh.. forgot to CC to SLUG earlier.. We have snapgear units at the moment. I have verified that while yes, you can do policy routing, you can't specify the individual vpn as the destination because they all go through interface ipsec0 (at least applicable for SG530 and SG560). I can't tell for sure from the reference manual for the Netgear FVS114 for example whether it can do the required policy routing for two or more destinations with the same LAN IP address range. It talks about "classic routing" which makes me doubt it can do it. Also couldn't find and occurance of "GPL" in the ref. manual.

[SLUG] linux firewall/vpn devices wanted
Something sub $500.00 that's small, runs linux and is customisable. It probably should have 256MB of RAM and at least the same in flash and two ethernet ports and at least one USB port. Now I can probably do this with a small form factor box with a via fanless motherboard in it. I've looked at NSLU2 and similar but they're a bit light on RAM and flash. My task is to obtain/build a unit to be the VPN endpoint for many clients' LAN's and the client's LAN's may also have the same LAN IP addresses. This means policy routing needs doing. Something I haven't really had a chance to sink my teeth into yet. The customers will most likely have one of the same boxes installed at their end.

I've not really dealt with LDAP much but for the application I'm writing it will need to act as an Active Directory Server at some stage in the future. We have our own database of people and when we set login='Yes' we need to create the user account and apparently a heap of other stuff such that people using Windows workstations can now login to the domain, email, proxy, ... etc with those credentials. I have it already doing the standard unix login with no LDAP. ie /etc/passwd, /etc/group, /etc/shadow. I appreciate that this is a LOT of stuff and there is the possibility of payment to get this done. Haven't run it by the boss yet but from a time perspective it would take me far too long. What I really need to know sooner rather than later is what data I need to store in our postgresql database. IE what the LDAP schema is. We can work out the other bits later.

Re: [SLUG] Document Management Systems or ECM
Phil Scarratt wrote: Hi all Wondering what people's recommendations/experiences with document management systems (or ECM systems) are? I've got to select a DMS/ECM for a non-profit organisation (actually a publisher) and have Nuxeo, Alfresco and OpenKM on the shortlist. TIA Fil Hi Phil, 11 years in that industry must be good for something, I suppose :-). Of the three DM/ECM products you mention, I have experience with Alfresco, and passing knowledge of Nuxeo (as well as far too many brain cells wasted on their proprietary brethren, e.g. Documentum, TRIM, Stellent/Oracle, IBM Content Manager) There are a few issues outside of technology that you should think about regardless of your choice. Are you after DM, or the whole ECM box-and-dice? (RM, DAM/Image management, Archiving, workflow/bpm, WCM ... and DM). There is overlap, but ECM is a cumbersome beast if all you want is DM. Are you prepared for the cost/effort? Not talking about software here, but the key to successful DM/ECM projects is managing them as a change management exercise, which means "people" costs. Making the change to a managed DM/ECM environment is often a huge cultural shift, and the best technology can wither and die if the organisation has a bad reaction. On the Alfresco front, it definitely has some advantages. There's local support here in Sydney, the product has a great roadmap, and John Newton's team seem quick to pick up the technology trends in ECM (e.g. they had CMIS prototype support in the same month the standard was announced). Given my particular biases, I like it because it's also technology agnostic under the hood, giving you OS, database and app server choice. Another big plus is that it is definitely a "growing" product and company. You aren't going to be left with orphan-ware in two years' time :-). Other current trends they seem to be following are heavily tied to collaboration, so if that's a current or future requirement, it has some benefits. Probably the only major gotcha I'd warn about is the enterprise version trap. Some of the nice bells and whistles are only available in the paid version. No problem with this, per se, it's their business model and best of luck to them. They do, however, have an unusual support model where support partners agreeing to partner with Alfresco on the enterprise edition are contractually bound to *not* support the community edition. Again, that's not really a technology issue, more a business one. You are in luck again, as there are both kinds of support available here in Sydney - enterprise partners who only do enterprise support, and other support outfits that support both (without the "ent. partner" label). Anyway, that's my 2¢. If that raises more questions for you, please feel free to contact me.

Re: [SLUG] How do I mount a RAID1 disk?
Oh hi Mike, Raid 1 you should be able to mount as it's native filesystem for recovery in read-only mode. EG mount -t ext2 -o /dev/sdb3 /mnt/recovery You mentioned LVM. That's going to be your problem for now. You need to make sure you have the lvm2 tools installed. Try 'pvscan' it should list the physical volumes (aka partitions in this case). 'vgchange -ay' should 'activate' all the volume groups. Then if that's done you should now find you've got some logical volumes... 'lvscan' will tell you. Then it's going to be something like... mount -o ro -t ext2 /dev/VolumeGroup/LogicalVolume /mnt/recovery Note that I use the -o ro to mount read-only as you're less likely to fsck up the data.

Hardly optimal but we did manage to get around it by running another MySQL server on the LAN and doing the ignore on that, then replicating from that to the remote site. We had a physical server laying around but these days something like OpenVZ or KVM (or other virtualisation systems) would do the trick. Actually... you don't have to do that either...

Well SOMETHING is obviously hanging onto the sound device. If you're prone to having applications directly access the sound device you're likely to run into this problem. There's a bunch of sound system LAYERS available for GNOME/KDE depending on what stage of evolution your system's at. Try esound-daemon (esd) on FC5. Then you change the apps to use this sound system layer which is sort of like a software mixer thus allowing multiple applications (and the desktop's bells and whistles) to access the sound device concurrently. The situation has drastically improved in Fedora Core 6 and Fedora 7. You should also try turning off your GNOME/KDE's desktop sound effects to help eliminate that problem. I'm not an expert on desktop audio but there's a lot of stuff there to play with..

Q1, Q2, Q3 A1) A quirk of raid1 mirror's on Linux software raid is you can usually mount one of the components for recovery. IE they're pretty much exactly the same. EG if /dev/md0 is made up from /dev/hda1 and /dev/hdc1 and you booted from a CD that doesen't do RAID you could do "mount -o ro /dev/hda1 /mnt/recovery". This can also happen with some hardware raid cards if you pop the drive onto a non-raid controller. It's much more interesting for other raid types. So much so that if you have Logical Volumes on a raid1 and zero out the raid blocks then LVM goes to hell because it now finds two duplicate volumes. Further fun happens when you plug in another hard disk from another system which has the same Volume Group but you can play with that another day - at least it lets you know and choses only one to run at a time. Anyway.. I digress. Yeah for software raid1 the uuid for the array, and each of it's components will be the same. A2) To change it... you'd better boot off a rescue CD and learn/practise using the mdadm utility. I'd suggest something like... mdadm --assemble -U --uuid=956c339-fa5e-45d9-ab13-e92a9597ab20 \ /dev/md0 /dev/hda1 /dev/hdc1 Or as the case may be editing the /etc/mdadm.conf (/etc/raidtab on really old systems) and/or /etc/fstab A3) think how the kernel starts up and runs from the initial ramdisk. The answer lies within... because frankly all the stuff on your regular filesystem, eg /etc/fstab and /etc/mdadm.conf can't be read until the kernel can find the filesystem. So you will find that whatever created your /boot/initrd* file did so by thinking about what sort of filesystem it would need to find. On Fedora for example the initrd is a gzip'd cpio'd filesystem in which you'll find /etc/init which happens to be a nash script (red hat's cut-down bash). In there you'll find magic stuff like insmod scsi, insmod raid1, raidstart /dev/md0, mount /dev/md0 /rootfs, switchroot Of course once the initial ramdisk mounts the root filesystem proper it then may go run something like /bin/init which finds it's way to /etc/rc.d/rc.sysinit (fedora/Redhat/Centos) which as part of it's process THEN looks at /etc/fstab and here's the funny bit... it tries to mount all the filesystems mentioned (with the auto attribute) but only if not mounted already.. now the root filesystem IS mounted already so again the /etc/fstab entry for the root filesystem is not used. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] SIP/IAX testing...
Hi folks... we're moving to a temporary office and so forth in the next 14 days and we've decided to go voip for our phone services. I'm in the process of trialing several voip providers and in the course of doing so I've setup guest access to our Asterisk server meaning you can call us over the net using SIP or IAX protocols. We're on the following URI's for retail sip:[EMAIL PROTECTED] [EMAIL PROTECTED] iax:[EMAIL PROTECTED] also sip:[EMAIL PROTECTED] should go to our call redirector menu.

Unfortunately mISDN is generally a pretty poor quality piece of code, and faxing in general is dodgy under Asterisk. My best suggestion would be to use Bristuff instead of mISDN, and try either of these combos: * Bristuff + Spandsp (no idea if this will compile) * Bristuff + iaxmodem + hylafax Bristuff is a patchset (the author refers to it as a "spoon") to Asterisk, Zaptel and Libpri. The advantage is it allows you to access your channels in a Zap-like manner and is much less buggy than mISDN (no bri software is that terrific though imho). Not sure if the netjet even has a driver for Bristuff or not, something to look into obviously. If you want to give Bristuff a go, download the latest version from www.junghanns.net/downloads/ and extract the tarball, inside is a script that grabs the correct copies of Asterisk, Libpri and Zaptel, patches, compiles and installs them. You may need to fiddle around manually to get spandsp in the picture. I have an older Bri card sitting around if you may need it, not sure if it's Bristuff supported though. OK sounds like I should look into bristuff. anyway, hope this helps, worst comes to worst you could divert the isdn line. Umm how do I divert just ONE number out of the hundred group on our ISDN line? Telstra say they can't do it - it's ALL or NOTHING. Is there a way to deflect the call to another number (possibly at our cost)? In any case I have been searching ... and searching since my last post and it looks like a Netgear RT328-S router is probably going to do the trick for now.

[SLUG] Cheap USB phones working with Asterisk
A few months back I bought a cheap USB telephone which of course came with only Windows software. It was very cheap so I just took a punt, which after a few days hard work has now paid off. The phone comes up as:- [EMAIL PROTECTED] ~]# lsusb Bus 001 Device 007: ID 6993:b001 Freshtel FT-102 VoIP USB Phone and a bit of research suggested the use of the yealink kernel module - Edubuntu 6.06 detected this when I plugged the phone in. Fedora Core 6 does not have the module built by default so I built that see my earlier post about building a module here:- http://lists.slug.org.au/archives/coders/2007/01/msg7.html Once the module's built and loaded see kernel doc's Documentation/input/yealink.txt file for how to test, although they fail to mention the need to enable the mic and turn up the volume with alsamixer - something which would probably be obvious if I had a gui on the machine. Once your satisfied the audio works and you've written your name on the LCD screen, turned on and off indicator lights etc you can move onto the application 'yeaphone' which can be found here:- http://www.devbase.at/voip/yeaphone.php The yealink guys do have Skypemate for Linux on their website so they at least recognise some value in providing for Linux. For my application I didn't want to run Skype or for that matter any GUI program. I've since built a Fedora Core 6 RPM for the yeaphone package which hopefully he'll put up on the website, if not try here:- http://www.linuxhelp.com.au/free.shtml I've also sent these off to the tech support at www.yealink.com in the hope they'll put them up there as well. Can somebody build a .deb package for Debian/Ubuntu thanks! I might see how I go just compiling it on Edubuntu 6.06 for starters. If you're not using an RPM base distro have a look at the BuildRequires lines in the yeaphone.spec file on my site to help satisfy dependencies when building the source. In particular, see if linphone for your distro includes the patch set the yeaphone author has put up for linphone-1.6. Our software site is http://www.linuxhelp.com.au/free.shtml Once it compiles and installs do "man yeaphone" and there's a procedure for setting up your sip profile the first time round. After that you just run 'yeaphone' , punch in some digits and press the green button on the handset. IE you don't touch your computer to make or receive calls. The only silly thing is you can only exit the app by pressing CTRL-C. Fedora Core 6 people can just download my RPM and install with rpm -Uvh yealink-0.1-0.i386.rpm which will probably give you a list of things you'll need to install with your favourite package manager eg: yum install linphone libosip2 ortp -- -- Grant Parnell - senior LPIC-1 certified consultant Linux User #281066 at http://counter.li.org (Linux Counter) EverythingLinux services - the consultant's backup & tech support.

[SLUG] Attn Friends of Anthony Rumble
Anthony has a lot of friends from SLUG and you all deserve to know that he's been stuck in Intensive care since the 17th of March. Without going into a lot of detail his symptoms are much like severe pneumonia. He's been on a respirator and under sedation until yesterday morning and for a while we were very concerned about whether he'd make it or not. He's showed significant improvement but now's the time for words of encouragement or reminders of good times from friends. If you feel like sending get well cards they can go to PO Box 6262 Silverwater, NSW 1811 or you can email me a note and I'll make sure he gets them. If you want to help in another way, we've been finding it tough here at ELX and if you want to liberate our warehouse stock that's fine too. Be sure to check it's in stock, buying stuff that isn't just wouldn't help a lot. Company worries is one thing he could do without right now. We expect him to be off work for a good few weeks at least. Finally, I appreciate whomever decides to approve this email going to the announce list. If it helps, call it a favour for the Ex-president :-) -- -- Grant Parnell - senior LPIC-1 certified consultant Linux User #281066 at http://counter.li.org (Linux Counter) EverythingLinux services - the consultant's backup & tech support.

Re: [SLUG] making boot floppy 'no space left'
Effectively the mkbootdisk command builds the image in temp disk space then uses 'dd' (or cp?) to write to the floppy device. If either there's not enough space in /tmp or the floppy isn't formatted ok you're going to have problems. If /tmp is full firstly try deleting stuff then try creating /home/tmp with same permissions then "mv /tmp /tmp.old; ln -s /home/tmp /tmp" You're probably going to need at least half a meg of temp space before it does the compression. It looks more like the target system didn't have enough space. This usually means the floppy needs reformatting. "man fdformat" eg: "fdformat /dev/fd0H1440" - frequently I find failures because a) the floppy drive is old/dirty/disused and secondly the media has been laying around gathering dust. Before you start, flip the drive door open and blow air into it to dislodge dust. Manually inspect the media for crap inside the jacket - it can damage the drive too.

[SLUG] ComputerBank Meeting Sat 20th?
Apologies if you receive this twice, I've bcc'd the LCA delegates mailing list. ComputerBank NSW and ComputerBank Sydney are two organisations in need of repair. Their purpose is to take old computers and either use environmentally friendly recycling or re-task them and give them to community organisations (or individuals) who would not otherwise be able to afford a computer. These organisations are suffering from lack of volunteers and a proper committee, funds, premises and general organisation. I have proposed a combined meeting for the 20th for both organisations. I originally thought there was still some LCA2007 activities happening on the Saturday morning. Now there's nothing. So I suggest we go somewhere central to all who'd like to attend. If you'd like to attend email me and/or update the LCA wiki http://lca2007.linux.org.au/ComputerBankSydney Needed to discuss are a) who's going to be treasurer (for CB NSW) and b) either paying rent for some warehouse space at ELX or taking over the lease or finding somewhere else. Roughly 1/3 of the donated equipment is in the ELX warehouse occupying roughly 10% of the floor space. ELX pays over $30K per annum for the warehouse rent and frankly NEEDS something to help pay the rent (other suggestions welcome in private emails). c) followup with meeting held at Penrith council on December 7th.

Then, we run #make #make install instead of #make modules #make modules_install #make #make install Hope this helps. You're sortof correct. The bit about chosing which modules are enabled is still exactly as you describe, however, with 2.6 kernels you don't need the whole kernel source to be there to build and install a module and hence you don't need to build a kernel (or have one built) during the process. It's MUCH quicker to a) obtain the dependencies and also b) just build the particular module you're interested in. You can in fact follow your procedure exactly and build the kernel and selected modules but it takes longer. IE on fedora core 6 you only need install these:- kernel-headers (701K) and kernel-devel (4.6M) compared with the kernel source RPM ~ (13M) Then you grab some 3rd party (or updated/patched module) like this mISDN.tar.gz cd mISDN-1_0_4 make install modprobe mISDN ... Some of you may be familiar with dkms which has similar aspects but is way cool because it will rebuild and install your modules on system startup if you run a new kernel. Hmm...

[SLUG] JMicron woes....
I've got a GA-965P-S3 motherboard with on-board JMicrcon controller. I've been battling for about 3 days now and am just about to shelve it. Looks like there's a lot of Core2 Duo motherboards with this controller and IDE/SATA problems. Times like this I wish customers would consult me before buying the hardware. https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/57502 https://wiki.ubuntu.com/Core_2_Duo_Support http://www.fedoraforum.org/forum/archive/index.php/t-122892.html google for "JMicron SATA linux" The system has 2 x 250GB SATA drives which I was hoping to use in some sort of RAID-1 mirror - either HW or SW raid. It also has an Adaptec 2100S RAID controller with 2 70GB SCSI drives. There's an optical drive on the ONLY PATA port which comes up AFTER the SATA drives on /dev/hdf or /dev/hdj or something if you're lucky. I actually wanted to install Centos 4.4 on it but had trouble getting it to find the install media - looks like the 'all-generic-ide' kernel option helps there (just tested that) but the install still locks up... trying via NFS next - actually that kernel option upset the controller and was fixed not by hard reset but power down! Anyway Ubuntu 6.10 worked with the SATA and I2O controller so I installed that on a small partition on the I2O/SCSI raid array. Fedora Core 6 wouldn't see the SCSI Raid as an install target even though cat /proc/partitions showed the partitions from the Ubuntu install on /dev/i2o/hda, /dev/i2o/hda1, /dev/i2o/hda2 etc (I need to file a FC6 bug). I installed that on one of the SATA drives then rebooted into Ubuntu, copied the Fedora Partition and configured GRUB to use the Ubuntu kernel & initrd but boot the Fedora system and after copying /lib/modules/2.6.17 from Ubuntu it worked just fine. Now I have a working system... It would be NICE to be able to use the other 2 x 250GB drives though. I'll await some suggestions there but in the meantime I'll configure the apps. I can PLAY with the system by removing the SCSI system to protect the setup. Also on the side, the inbuilt Marvel NIC wasn't recognised in Ubuntu but was recognised in the FC6 kernel but complains a lot suggesting it might be buggy, I disabled that and inserted a Netgear FA310TX. Incidentally under the fedora kernel all the drives come up as /dev/hda, /dev/hdb, /dev/i2o/hda and under the Ubuntu kernel they're all /dev/sda, /dev/sdb, /dev/sdc. I should point out that whilst using the Fedora core 6 install kernel with the SATA drives connected to the on-board SATA raid I configured them as software raid and they appeared to get corrupted. Also.. beginning to think that either support for the JMicron chipset sux because I even get errors with dd if=/dev/zero of=/dev/sdb6 after about 5 to 10 minutes. Either that or I've got 2 brand new dud SATA drives that fail around the same spot ... Nah!

If your system cannot be taken down then you can basically adjust my previous post such that the new drive is prepared on another system. You can dd to a file the first 100Mb for example then copy that file containing partition table & MBR and then dd on the target system. You'd have to prep the target system from a rescue/live CD. Problem being there is a problem with the difference between the running state and the shutdown state - eg lock files, pipes. A similar situation occurrs when you just pull the power plug on your system. In the case of attempting to clone you're racing against time with files that are being written/deleted on the source system. If you can shutdown as many non-critical applications as possible and frequently rsync you may reach an acceptable level of compromise, you can then shutdown the old system and turn on the new system and cross your fingers. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] Proposed ComputerBank's AGM
Hi, I'm doing my best to get all the people involved in ComputerBank in this state at least talking to each other. I know a lot of SLUG people have been interested in the past and it's the only reason I'm CCing that mailing list. Followups may be discussed off or on the SLUG list but I request you CC the [EMAIL PROTECTED] mailing list too. To limit SPAM it's a members only posting thing but I'll approve relevant stuff. One of the things we badly need to do is organise an AGM for ComputerBank NSW and also ComputerBank Sydney. I am putting forward by way of suggestion some dates to hold these AGM's - Sunday the 24th of December or Saturday the 30th December or Sat/Sun 6 & 7th of January or perhaps after the close of LCA on the 20th of January at UNSW. Venues: My place at Concord for a BBQ, ELX Silverwater (as I have said I'll open up computerbank on 6th & 7th - but that's not yet confirmed). Other suggestions? Picnic venue, beaches, Clubs whatever. Geoff, hopefully I haven't overstepped here in organising this but I vaguely recall you suggesting I organise a time and a place for a meeting. -- -- Grant Parnell - senior LPIC-1 certified consultant Linux User #281066 at http://counter.li.org (Linux Counter) EverythingLinux services - the consultant's backup & tech support.

Since /dev/input/mice is already mentioned in your /etc/X11/xorg.conf you're seeing it just work.

Pull the kernel source for drivers/usb/input/mtouchusb.c and make sure the exact model is listed, as there's a note in there about the Y axis handling that makes me wonder if you don't have hardware with a "feature" corrected. If that still sucks you'll need to swap the axises in X11 as the input layer doesn't allow such niceness. Hope this is somewhat helpful, Glen Just letting people know how I got on with this. Basically all WILL be well with the kernel module usbtouchscreen as significant work is BEING done in this area. The main problem is with people agreeing on calibration support. For me, I was happy to use the Touchware drivers supplied by 3M for Fedora Core 4 which do hardware calibration (ie the calibration gets stored in the touch screen hardware). For your normal desktop situation it's as easy as installing one RPM, removing the mutouch.ko module (it conflicts with the Touchware one) then executing /etc/twscreen/TWCalib/TwCalib as root once to do the calibration. They do supply a source RPM but I couldn't get that to compile for FC5. Here's what it contains. It's worth noting that each time it starts up and shuts down it finds your X config (XFree or Xorg) and edit's in/out the bits required. /etc/init.d/TWDrvStartup /etc/twscreen /etc/twscreen/TWCalib /etc/twscreen/TWCalib/MultiMonitorTool /etc/twscreen/TWCalib/TwCalib /etc/twscreen/TWXinputInstall.perl /etc/twscreen/install /lib/modules/2.6.11-1.1369_FC4/kernel/drivers/input/touchscreen /lib/modules/2.6.11-1.1369_FC4/kernel/drivers/input/touchscreen/TWDrv.ko /sbin/TWDrvStartup /usr/X11R6/lib/modules/input/TWXinput_drv.o /usr/lib/libMultiMonitor.so /usr/lib/libTwCaliblib.so /usr/lib/libTwGraphics.so /usr/share/doc/TWDrv-5.64 /usr/share/doc/TWDrv-5.64/BUILTWITH /usr/share/doc/TWDrv-5.64/Readme.txt Now I'm just having a lot of 'fun' getting all this together on a read-only filesystem on compact flash.

Re: [SLUG] Microtouch USB touch screen X/Y axis swapped
Just following up with more info. It seems there's been a fair bit of consolidating & work in this area in the kernel modules between 2.6.15 and 2.6.18. In 2.6.15 the module was mtouchusb and this and others have been merged into a more generic one called usbtouchscreen kernel/drivers/usb/input/ is where they are. The good news is there is in fact a swap_xy parameter in the stock 2.6.18 kernel module and it works. The bad news is that my x and y direction is opposite to what it should be. IE move your finger left, the pointer goes right. So I added 2 more module parameters invert_x and invert_y and recompiled the module but for some reason the module isn't behaving... it's my day off so I've yet to discover whether it's my module build process or the modification I've done (ie can't test remotely). The module does load but when Xorg tries to talk to /dev/input/mouse1 it gets an open error. There seems to be some heated debate about where the calibration should happen as well. In the RS232 version it was in the xorg.conf file. Any tips on inverting X and Y and scaling them in the xorg.conf file appreciated.

[SLUG] Microtouch USB touch screen X/Y axis swapped
I just got some LCD touch screens in for a customer and unfortunately I didn't get the serial ones I was expecting, instead I have the USB ones. It's pretty cool how it works, just plug it in and start moving your finger round the display and it just works - Fedora Core 5. Only thing is the Axis are swapped around and it needs some sort of calibration. What I want to know is where to start looking to fix it. It appears that somehow the mtouchusb kernel module loads and this creates some stuff under /dev/input which ends up working in parrallel with the PS/2 mouse I already have plugged in. If somebody could explain how this multiple input stuff works, and can be configured, that would be useful too. The answer may possibly be in configuration of these bits. Kernels 2.6.15-1.2054_FC5 (standard) and 2.6.18-1.2200.fc5 (most recent update) make no difference. xorg-x11-server-Xorg-1.0.1-8, xorg-x11-drv-microtouch-1.0.0.5-1.2, xorg-x11-drv-mouse-1.0.4-1 are installed. The man page for the xorg microtouch driver is next to empty, says it needs to be written. If somebody has their Xorg source unpacked maybe see if there's anything more useful there but I doubt it. For the serial version I used the xorg 'microtouch' driver, this USB one works without modifying the xorg.conf file. I would be happy to modify the xorg.conf file if the USB version could be coaxed into looking like a serial port. cat /proc/bus/input/devices gives I: Bus=0003 Vendor=0596 Product=0001 Version=0400 N: Name="3M 3M USB Touchscreen - EX II" P: Phys=/input0 S: Sysfs=/class/input/input3 H: Handlers=mouse1 event3 B: EV=b B: KEY=400 0 0 0 0 0 0 0 0 0 0 B: ABS=3 lsusb -v gives Bus 001 Device 002: ID 0596:0001 MicroTouch Systems, Inc.

Re: [SLUG] UPS software
This is good news but for the rest of us, probably 'nut' is the software
you're after - basically has a bunch of plugins for UPS model support. If
your UPS does RS232 control line based signalling++ then you can write
your own config for the generic serial UPS driver.
++ by this I mean things like 'CTS is high for power good, CTS is low when
power is bad' and variants on this including edge trigger.

[SLUG] ComputerBank NSW list server up
Hi, I've personally paid for and registered the cbnsw.org.au and cbsyd.org.au domains. I have temporary websites attached to both of those at the moment more as placeholders than anything. However the main point is I do have lists.cbnsw.org.au setup and working so people within Computerbank organisations in NSW can begin communicating irrespective of what happens with the actual websites. I've notified just a handful of people directly and the lists in the CC line, apologies for those that receive this twice. ComputerBank NSW and ComputerBank Sydney are both separate legal entities.

In my experience I have found that installing grub on each component
device is the most reliable. Have a look at an existing
/boot/grub/device.map file. It's a very simple file that explains to grub
the relationship between (hdX) and /dev/hdX so theoretically you could use
a file like this:-
(fd0) /dev/fd0
(hd0) /dev/md0
(hd1) /dev/hda6
I can't remember why I don't do it that way, possibly grub does not
understand software RAID as you suppose. I don't think lilo does either.

I think you're confused. If grub or lilo's purpose is to load the kernel
then how would it be able to use the kernel raid driver to load the
kernel?
Oh! I know what you mean, when you run "lilo" at the command prompt the
INSTALLER part knows about the raid device and knows to put the master
boot block on both root devices. The boot-time executable therefore does
NOT know about software raid. Therefore you can't use anything other than
RAID-1 for /boot when using GRUB or LILO.
As a footnote, if I'm wrong about it installing the MBR on both root
devices the effect on LILO only would be that the secondary component
drive would not have an up-to-date record of where the kernel and initrd
blocks are on the component partition. GRUB on the other hand knows a
little more about finding blocks on partitions/filesystems and will cope
better. It's why you don't need to run 'grub' every time you change
grub.conf/menu.lst like you have to run 'lilo' every time you change
/etc/lilo.conf.
The above is why when using lilo I carefully partition the drives to
ensure the same geometry is used and the same number of cylinders are used
for the boot partition and the same partition number within the device is
used. This way you can literally swap the IDE cables around if your
comp
Re: [SLUG] Two grub/RAID questions?
I'm not going to attempt to answer all these questions as I'm out of time...
Software Raid devices do not have partitions on them. You would typically
mke2fs -j /dev/md0 to format it, alternately put LVM on it but that's
another topic.
Software RAID mirroring has a nice side effect, you can mount half of the
mirror in it's own right in case of emergency. Similarly, the boot files,
namely the kernel and initrd will appear in consistent locations within
each component device.
Thus if /dev/hda1 and /dev/hdc1 are components of /dev/md0 you can do this:-
$ touch /boot/hereplease
$ grub
grub> find /boot/hereplease
(hd0,0)
(hd1,0)
{your actual results may vary}
grub> root (hd0,0)
grub> setup (hd0)
grub> root (hd1,0)
grub> setup (hd1)
grub> quit
$
I typically do a find to make sure GURB's idea of the partitions is in
line with what I am thinking. The setup command does all the hard work for
you of finding the stage1 and stage2 files and writing the boot sectors.
Another thing to help is to write yourself a device.map file somewhere in
/tmp or something just for doing the recovery work.

Re: [SLUG] DHCP client vs sendmail
Here's something that might make it easier on everybody if you have control of the mailserver/firewall. Consider this rule:- /sbin/iptables -t nat -A PREROUTING \ -i $LAN_IF -p tcp \ --dport 25 \ -d ! 192.168.0.0/16 \ -j REDIRECT --to-ports 25 The second last line probably isn't needed, except if you terminate a bunch of VPN's. IE don't do the NAT if it's going from one of your LAN's to another of your LAN's. Essentially what happens here is the firewall traps any outgoing SMTP traffic and redirects it to it's local MTA which presumably allows hosts on the LAN to use it as a smart host (ie permits relaying). So how's this work? well whatever IP, hostname or whatever is looked up by the sending mail client (or it's local MTA even) it ends up going via the firewall's MTA regardless. The firewall's MTA then uses whatever site policy is appropriate AND because it's receiving the message then relaying it the HELO/EHLO handshake will be correct. This also ensures that all emails from the site are logged - even if some nasty virus thingy managed to send it.

on ports 81 and 8000. Not usually a problem. I have logged into the proxy
server and successfully used the services with lynx so there really isn't
a firewall issue as far as I can tell.
When I set the http_proxy environment variable to http://127.0.0.1:3128/
lynx will use the proxy. When I try this:-
lynx http://www.some.site:81/ it returns a 503 and I can see NO PACKETS
going to the site with tcpdump. Exactly the same with port 8000. The error
page returned by squid reports 503 and permission denied, as does the
access.log I tried the same thing from our proxy server which is the exact
same version and there's no problem leading me to think it's configuration
of squid. I tried setting up squid from scratch again and no luck although
I did not clear the existing cache (it's a busy proxy, don't want to do
that). I will try moving the cache away after hours though.
The response is so quick it's not even trying (as verified by packet
dump). Any thoughts from other experts?

[SLUG] VIA EPIA EN15000 at Sunday's workshop
One of my supplier's has been kind enough to let me evaluate one of these boards and since I was kinda hoping to come along to the SLUG workshop on Sunday anyway I figured it'd be fun to bring it along. I'll fit it into another case so we can use a CDROM drive. BYO HDD if you want, it takes PATA and SATA. Here's a link to the motherboard info, we've got the 1.5GHz version. http://www.via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=399 Of interest are it's multimedia/TV features. For example it has a HDTV encoder (can also do regular definition composite video I presume). I don't have a HDTV myself or a set top box. It's also got gigabit ethernet and the whole unit it's in isn't much bigger than a white pages volume. -- -- Grant Parnell - senior LPIC-1 certified consultant EverythingLinux services - the consultant's backup & tech support.

[SLUG] 2006-2006 President's Report
2005-2006 President's report Thankfully SLUG still exists and as far as I know hasn't got any significant debts so whatever's happened in the past year can't have been all that bad. In fact the worst that's happened is the SLUG server being offline for a few extended outages due to hardware issues which thankfully have now been sorted recently by removing hardware from the equation - ie it's now on a virtual server. Having said that the membership itself has been on the decline in recent years and prior to tonight we had about 50 financial members. This has had some impact on the events SLUG has been able to hold because we don't have that financial buffer to fork out in advance for cost of putting on events. To spite this there have been many exceptions where individuals have decided to get up and run an event themselves and the committee whole heartedly encourages this. Some significant events --- DebSig - I only just started going to some of these in the past year. I had felt that since I didn't use Debian it would be of little interest, however, as Craige pointed out it's not really about Debian (or Ubuntu) specifically anymore and is a great laid-back alternative to the main monthly meeting. It's in a pub, less organised, more chatty and that's all good. When it comes to the main monthly meetings I have attended most of them since I've been going to SLUG and some rock and some suck - that's the way it goes due to a variety of factors. Some months I wish I could be in 2 places at once during the second half of the meeting. Peter Miller deserves special mention for organising 2 CodeCon events that I wished I could attend and I've heard nothing but good things about them. Ashley Maher organised a CodeFest and had an installfest. Unfortunately the Installfest didn't get the numbers for success at UOW but the point is he tried! The CodeFest hosted at ACS Sydney on the other hand went well, but then all you need is power and desks, food and coders ;-) Mid May 2005 Sarah Kahn managed to get us a booth at the Education Expo at Rose Hill and we had quite an enthusiastic turn-out of helpers from SLUG to occupy the booth, demo linux, chat to the general public and actively go round to other organisations present and promote Linux. Everyone involved deserves a big round of applause. Later in May we asked SLUGgers to submit a message saying why they should be sponsored to go to an OSS workshop with Sebastian Rahts. Jamie Honan was the lucky individual we sent along to find out what it was all about. We later gave Jamie the chance to give a report at a SLUG meeting. Many SLUGgers were keen to help out with Software Freedom Day in Sydney and we took the Open Source message to the streets handing out CD's and brochures about what we'd miss without Software Freedom. This was followed up by a mini-installfest at UTS afterwards. Just for interest's sake I've manage to dig up and summerise the main monthly meetings we've held the past year. Monthly Meeting Topics -- Apr 05 - I attended LCA2005 wrap-up OpenSkills network May 05 - I attended Ubuntu Down Under report The R environment for statistical computing Jun 05 - I attended Linux Distro package manager comparisons Setting up an OpenLDAP environment using Linux Jul 05 - I attended Linux at the Lorien Novalis School Apache 2.0 / mod_perl wrap-up + redundant webservers Aug 05 - Don't think I made it XFce lightweight desktop OpenLDAP security with OpenSSL and Cyrus-SASL Sep 05 - I attended Desktop Introduction for newbies Virtual Machines for fun & profit (aka Your own personal mainframe) Oct 05 - I attended SELinux (Security Enhanced Linux) Working remotely - tricks tips and hazzards Nov 05 - I attended Linux Australia live webcast Careers for Geeks Dec 05 - I organised and attended Zig Zag railway trip (Dec 4th) Scared Scriptless (Dec 9th) Jan 06 - I was at LCA Grid Computing - processing physics data worldwide ROOT Toolkit - graphical analysis toolkit for physics data Feb 06 - I attended Training Greenpeace in (how to use) OpenOffice Merlin - Open source POS software used by Kennard Hire -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

Can you make the entries for people who haven't yet accepted a little bit lighter ( or similar) or perhaps bold the "not yet accepted" bit. It's really hard at the moment to distinguish people who are running from people who aren't and this would help. Ok will do. Also, why is there still a listing for "Honourary committee member"? As I recall, this is completely unofficial (ie the constitution does not provide for such a position) and was only ever there because for a while it was thought under 18s couldn't be on committee officially. Since we later decided that they could be ordinary members (but not executive members because they can't act as signatories), there seems no reason to keep mentioning it in elections. If the committee needs to be larger, then we should change the constitution, if not there's no reason for the position. I felt that although the under 18's thing had been resolved there might be other reasons but I guess we can always add it again later. There's been no nominations anyway.

[SLUG] ComputerBank giveaway ABORTED for the weekend
Firstly, thanks to all those that turned up yesterday to help lighten the load of moving, it certainly was appreciated. Unortunately unbeknown to us Railcorp has fully closed the access to the Powerhouse for the weekend for the purpose of railway upgrades. They've been doing work there in the past but had still allowed road access so we really had no idea there'd be no access until Dan turned up this morning and tried to open up. We'll be catching up Monday evening to come up with a new plan. Personally I'm thinking we could do it one or two nights over the coming week or I might be able to get a day off work. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] Free computer equipment this weekend
Computerbank Sydney is on the move again and due to the timing we won't be able to spend time preparing stuff. One of computerbank's goals is to prevent computer equipment going to landfill so we're just giving as much away as we can to lighten the load this weekend. There are whole computers (PC and Mac and others!), monitors of varying shapes and sizes, printers, faxes plus rare spare parts you wouldn't have thought existed. There's even some phone and rack gear. We have a bunch of power supplies, 3GB disk drives, RAM, CDROM's and floppy disk drives already pre-stripped. None of the gear comes with any sort of warranty whatsoever! Before people even ask, don't bother asking if you can reserve anything. It's first in best dressed. There is plenty of parking space available and I'll try to bring a couple of trolleys on Saturday - these must not be taken away. SLUG people often help out other people so if you see a need or even have a spare PC you wouldn't mind get working cheaply to run as an experimental Linux box for yourself or somebody else then please pop by, we're open 10am till 4pm on Friday the 3rd of March, 10am till 5pm on Saturday & Sunday. The only thing we'd really like is that if you take a computer you should take a monitor too. If you ever wanted to experiment with a dual monitor setup here's your chance to do it for free. You'll find us at the Casula Powerhouse Arts Museum at Casula station. Dan Treacy will be there on Friday and Sunday, and I will be there on Saturday and probably Sunday too.

[SLUG] Nominations hotting up
Firstly it's good to see a bunch more nominations for the SLUG committee so keep 'em coming. But one suggestion I have is to at least ask the person you're nominating if they'd like to be nominated. A lot of the nominations have not yet been accepted. Also, according to our current membership data a number of nominees and nominators are not 2005-2006 financial members. I have still recorded the data though and there's no shortage of financial members who would replace the invalid nominations, however I'm pretty sure you have to be financial to be nominated.

[SLUG] Committee nomination: Grant Parnell for President (or VP)
I've been using Linux since about 1993. I've been going to SLUG for at least 8 years now. I work for EverythingLinux (ELX) and have an interest in the Linux market. I've been on the committee since 2004, first as Secretary then as President. I'm involved with OSIA and Computer Bank Sydney. I guess I prefer the command line to the GUI - old habbits plus things seems to work more consistently accross distributions. My preference is Fedora mainly because of habitual use. I want SLUG to be interesting for people and more than just an online resource for tech support and to do this we need more face to face contact and to involve more people in various activities such as hands-on workshops, demonstrations, community projects and social activities. SLUG also needs more members and so we have to broaden our minds and be accessable via different means such as radio broadcasts or webcasts, be contactable by phone or fax, publish the odd article, advertise in papers and arrange visits to schools or colleges which will attract younger more enthusiastic members to ensure SLUG's future. I would seek donations or limited sponsorship (possibly in the form of services) to help us. We'll team up with other organisations for some activities for mutual benefit. I am prepared to put my money up for kick-starting some events have a cover charge for. Finally, it's going to be a busy year for Linux in Sydney and we need to be ready to sieze opportunities such as LinuxWorld in March, CeBit in May and LCA next January. In summary I want to * Keep SLUG interesting * Attract more members * Raise SLUG's community profile * Promote "Linux for the good of the community" * Ensure people get some benefit for joining -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

I had hoped the proper URL would be accessable by now but I have managed to publish something to the SLUG site under my own login. http://www.slug.org.au/~grant/election.html will be updated from time to time with information about nominations, nominees and other status - including a link to the proper page when it becomes available. If any of the nominees wish to publish a short paragraph about what they hope to do for SLUG I would like to put that in as well. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] NetBSD live CD
Hey I know this isn't Linux but a lot of you out there also like BSD variants and therefore I'm forwarding this message. Perhaps we could collate all the feedback and send it - otherwise feel free to use the usual bug reporting techniques. -- Forwarded message -- Date: Wed, 25 Jan 2006 23:14:41 -0500 (EST) From: haidut at metawire dot org To: [EMAIL PROTECTED] Subject: NetBSD live CD Hello, I am one of the developers of Arudius - a live CD Linux distro targeting information security professionals. The CD has a large collection of security tools and a very small footprint (210MB) so it fits on a mini-CD, thus it can load its tools completely into RAM and run them very fast. In addition to this security-related Linux distribution, we also developed a NetBSD live CD focusing on the non-security community. It is called NeWBIE (or simply Newbie). This acronym is pronounced just like the word "newbie" and stands for (Ne)tBSD (W)are (B)urned (I)n (E)conomy, a naming convention similar to the one used for the well-known FreeSBIE CD. Newbie caters to the desktop-user (i.e. with applications for web browsing, chat, multimedia, document editing, etc) but will also serve as a core for creating a NetBSD-based live CD for network security auditing just like Arudius (see the website). We are also in the process of developing a DragonflyBSD version of NeWBIE. The goal of both CDs is to promote the usage of Linux/BSD and hopefully serve as useful tools for people who need that kind of software. We would appreciate it if you try out the CDs and give us some feedback on how we can improve them (i.e configuration, install additional software, etc). If you find any of the CDs to be useful, please mention them on your site or post a link to the homepage - http://arudius.sourceforge.net Thank you very much for your attention and if you have any questions feel free to send an email to [EMAIL PROTECTED] best regards, Haidut -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] fun with libcrypto.so.5 missing
Just thought this was an interesting edge of your seat type experience to share with people. What started out as a simple "why can't I send emails to this domain" ended up being a battle of wits to recover from impending doom. It turns out the target domain could send emails to my customer, send and receive emails from everybody else, but not receive any from my customer. My customer was sending and receiving other emails. Thankfully a tech from the target organisation called and found that my customer's server was attempting TLS email connections and then just dropping out. After a bit of reading & stuffing around I tried adding Try_TLS:mail.somedomain.com.au NO to the /etc/mail/access file and that allowed me to clear the backlog of emails ... for one domain. I tried some sort of global disable but didn't find one and then thought well maybe there's something else wrong and after a bit more hunting I did rpm -V openssl and found one of the library files corrupted. No problem, I still had the original install version of openssl in an RPM on the hard disk so installed that with the --force option to allow the downgrade and then tried rpm -V openssl again... This time rpm itself failed with a missing library error... oh shit! rpm -q openssl - error loading shared library rpm2cpio - error loading shared library So at this point I had plenty of RPM files (copy of the install media) which were completely useless to me right now. If you'd like to follow along with a test box you have physical access to (just in case) loginto it via SSH from another machine and then move /lib/libcrypto.so.5 (on Fedora Core 4) to somewhere else the system can't find it and pretend you haven't got it. Now the problem was how to I get the library back... any version that works will do! I had no physical access to the machine and it had just gone 5pm and nobody was there to ask to insert a USB key or something and I was logged in remotely via ssh over 2 ADSL links. Alright lets try copying the relevant file directly from another fedora box with scp ... connection refused... OH SHIT! lucky I was still logged in on some other xterms. Alright then... how about wget - error loading shared library how about links (didn't have lynx installed) - error loading shared library ncftp - yeah! it ran, I was able to connect to an FTP server of mine but in either passive or active modes couldn't get a listing or any files transferred for some reason. URM... was contemplating finding a short bit of perl code to facilitate a simple web fetch ... Then I thought hey! they can still receive emails I'll just do that... No luck... although it got there I didn't have a text based email client and no way to run any GUI utilities. I thought of metamail or mmdecode or something but alas didn't have any installed. I could ask one of the staff to save a file since they had Evolution running on the box but they weren't around. Argh... I just want some way of getting a file from A to B...then it hit me... B> nc -l 7000 >libs.tgz A> cat libs.tgz | nc mail.somewhere.com.au 7000 [anxious waiting period] B> tar -xzf libs.tgz - SUCCESS! Then I just copied these files (libcrypto.so.0.9.7f libcrypto.so.5 libssl.so.0.9.7f libssl.so.5) back into /lib rpm -V openssl All good!

Re: [SLUG] fstab weirdness
Well I'm not sure what the logic behind it was but for whatever reason the
update has renamed your filesystems. You can rename them back provided you
sync all the things that reference them.
1) use e2label to relabel them
2) change /etc/fstab to match
3) change /boot/grub/grub.conf so that the kernel lines have
'root=LABEL=/' for example.
With step 3, if you have /boot /boot1 and /boot11 then you'll need to
decide which is the real one - the root=(hd0,n) in grub.conf should also
match; n is the partition number starting from zero. Experiment by adding
bogus entries in the different grub.conf files and reboot to see which one
you get.
If you want to actually use a different one, then at the grub prompt go to
command mode and do the following;
find /boot/grub/grub.conf {finds /boot partitions}
find /grub/grub.conf {finds / partitions with a boot subdirectory - ie no
/boot partition}
root (hd0,1) {we'll use /dev/hda2 - think of this as chroot and subsequent
commands make more sense}
config /boot/grub/grub.conf {if we didn't have a /boot partition}
OR
config /grub/grub.conf {if we are using a /boot partition}
{ I think it runs the config, so you have to get back to command mode
again } setup (hd0) {this magic writes GRUB into the boot sector & tells
it where to find it's config next time it boots}
quit {system reboots? if not just hit reset button}

Took me a while but I'm downloading an x86 zip file... no idea what's in it, the sourceforge site Oscar pointed out is a bit light on for documentation.

[SLUG] Re: Osirix software port required MacOS-X to Linux
I've got a client that want's to port this software package from Mac OS-X to Linux and pay for it. I checked out 104MB of source code via CVS (I've attached the listing from /home/grant/packages/osirix) ... Not sure but it looks like some sort of C code but you compile it within this IDE http://www.apple.com/macosx/features/xcode/ I couldn't find anything resembling ./configure or a Makefile and the dev page isn't very helpful unless you're using xcode. http://homepage.mac.com/rossetantoine/osirix/Index2.html My Gut feeling... probably cheaper to buy a Mac - except he wants to deploy many times over, thus if it costs a few grand it's OK. The alternative would be to buy a Mac and large high quality LCD and the commercial version of the software and the annual license for each site. This is less than satisfactory as my client wants some customisation done to it anyway plus the doctors usually would have multi-head PC's decked out with a stack of LCD's occupying significant desk space. Any pointers to who can do this or which company can do this or which mailing lists to consult appreciated. We can probably commission a feasability study seeing as it's such a large chunk of stuff. -- -- Grant Parnell - senior consultant EverythingLinux services - the consultant's backup & tech support.

[SLUG] December get-together #2 Scared Scriptless
Following up from last Sunday's Zig-Zag trip where a few of us made it for a lazy day in the mountains away from the heat. It was suggested I get this announcement out early. This Friday is another excuse for SLUG people and their friends and family to come along to a great night of fun at the Clarence Hotel (corner Crystal St & Parramatta Rd Petersham). Scared Scriptless is the aptly named title of a regular Theatre-sports type event where teams compete by hacking together a piece of theatre inspired by audience suggestions, governed by some game rules that go for about 2 to 5 minutes and are then judged by the panel, the winners go to the next heat. It's frequently hillarious and it's great watching amateur thespians under pressure. Show starts at 8pm, tickets $5, food available. I'll be turning up around 7pm in SLUG shirt and cap again. It would be good to get tickets early and sit together but otherwise no booking necessary. Phone 0408 686 201 on the night if you're trying to find us. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] December non-meeting this Sunday
Traditionally SLUG doesen't have a meeting in December at UTS, instead we've done something else like a picnic or tenpin bowling. For something different this year I've come up with an idea for a non-technical SLUG family & friends tour on Sunday the 4th of December 2005. My idea is to do the Zig Zag historic railway trip. I have done this a very long time ago with some friends and although it's a long day it's worth it. You get to ride a steam train up the mountain and either Steam train or Rail motor back down plus there's a commentry, there's tunnels, photo opportunities, short walks and souveneirs. Date: Sun 4th Dec 05 Start Time: Depart Strathfield by train 08:31am< End Time: Arrive Strathfield by train 6:17pm Cost Adults: $20.00zz + $18.40cr (zz=zigzag, cr=cityrail ex central) Cost Kids: $10.00zz + $3.50cr Accessability: no wheelchairs via cityrail - should be ok by car Food & refreshments extra Website: http://www.zigzagrailway.com.au/ I've checked for cityrail disruptions and there is work on the inner west line which should not affect inter-city services and you can get right to Zig Zag by train and alight from the shortest platform in the CityRail network - only about 3m long. We will need to be in the front carriage but check with the train guard on the day. I (Grant) will be wearing a SLUG T-Shirt and cap and am boarding at Strathfield. Things you will need if bringing your own tribe:- snacks, cards, colouring books, gameboys, ipods, portable DVD, cusion/pillow etc for the journey to/from the city to the mountains to keep your sanity. Lunch is available for purchase at our half way point for the day which is the station at Clarence but towards the afternoon you'll need stuff although absolute worst case you'd be back at Central by 8:30pm but should easily manage 6:30pm. Timetable details:- Central 8:18am Inter-city service Strathfield 8:31am Parramatta 8:44am Zig Zag 11:05am morning tea Bottom Points 11:50am Steam train service Clarence 12:20pm Lunch Clarence 1:40pm Rail Motor service Bottom Points 2:15pm Workshop tour Zig Zag 3:41pm or 5:41pm cityrail services Parramatta 6:04pm or 8:04pm Strathfield 6:17pm or 8:17pm Central 6:30pm or 8:30pm Alternately if you go by car you can meet us at Clarence (10km from Lithgow) after 12:20 and catch the train down the mountainside with us and go back separately. Also checkout http://www.cityrail.nsw.gov.au/trackwork/index.jsp for Cityrail trackwork info a day or two before. -- -- Electronic Hobbyist, Former Arcadia BBS nut, Occasional nudist, Linux Guru, SLUG President, AUUG and Linux Australia member, Sydney Flashmobber, Tenpin Bowler, BMX rider, Walker, Raver & rave music lover, Big kid that refuses to grow up.

[SLUG] exporting contacts from Evolution 1.2.2-5
Firstly I have a customer who's developed a problem with this version of Evolution. -- quote -- COULD NOT CREATE COMPOSER WINDOW: UNABLE TO ACTIVATE HTML EDITOR COMPONENT. PLEASE MAKE SURE YOU HAVE CORRECT VERSION OF GTKHTML AND LIBGTKHTML INSTALLED. THE ERROR FROM THE ACTIVATION SYSTEM IS: CHILD PROCESS DID NOT GIVE AN ERROR MESSAGE, UNKNOWN FAILURE OCCURED -- quote -- This is the same machine they've been using for years now and it's intermittent, they get this when they click on new/reply and before the message editor window pops up. So...I have a need to convert someones contact list to something like Squirrelmail or Thunderbird (assuming it'll run). The contact list seems to be stored in a Berkley DB version 7 format if that helps - vaguely remember some way of dumping it but can't find it. The system is a RedHat 9 box and unfortunately - I'm trying to organise an upgrade - would have been done sooner if it weren't for the Pulsar ADSL card in it. ... Just got off the phone... good they'll take the upgrade suggestion, still means I have to figuire out the export - it's probably easier if I copy the data to a Fedora Core 4 box running a later evolution and go from there just to do an export. I'm off the hook for tonight though This time round I'm going to setup Cyrus-IMAPd for the shared email access they need.
