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.

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?

[SLUG] High System CPU usage and finding culprit
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

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.

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.

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).

This is my list of hardware: Asus P5Q SE2 motherboard Intel Core2Duo E7600 3.06GHz 1066MHz FSB 2GB PC6400 DDR2 RAM Asus GeForce GT220 1GB DDR3 video card 1.5GB Seagate 7200 RPM SATA HDD (ST31500341AS) Lite-On SATA 240x8 DVD-RW drive Silverstone LC10-E case 500W power supply Logitech diNovo Mini bluetooth keyboard and either of: Hauppage Nova-T-500 MCE dual tuner (PCI) Hauppage 2200 MCE dual tuner (PCI-E) I'll probably add a second tuner card once I've got it all up and running. 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. I'd like to order the hardware next week, and I'd appreciate knowing that I've chosen badly *before* I part with the money :-) Thanks, John -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[Fwd: Re: [SLUG] IOWait definition]
I have a machine with a good proportion of IOWait 20-30%. It does have local disks and it performs operations on NFS mounts. I just wanted to be sure if IOWait includes NFS activity or not. I also want a way if it is NFS to be able to say for sure if it is a bottleneck on the nfs client or server. NFS is not a linux machine so visibility is not allways the best. Grant Daniel Pittman wrote: Grant Street [EMAIL PROTECTED] writes: I was wondering if someone could point me in the right direction for some doco? I don't know of any, but ...

This is different from CPU time waiting for ... in that it implies the software is making no progress, but *NOT* that your CPU is spending cycles working on it.[1] - CPU time waiting for an NFS read/write to occur Yes, along with more or less any other disk I/O that happens to be run over the network -- as long as it is synchronous, and something is waiting on it. - CPU time waiting for a network buffer to be read/written to. eg waiting for a full buffer to clear. Generally not. I am not certain about blocking on a full buffer condition for sending data, but not for blocking while reading. - Anything else?? Any other synchronous disk I/O, certainly. Probably certain other, related, conditions where the kernel developers feel that the process is blocked on I/O. PS. How do you set/query the network buffers in Linux? Via the socket fcntl / ioctl interface, or via the sysctls in /proc/sys/net, which are documented in the standard Linux kernel sysctl documentation. All that said, you might want to tell us why you are asking, not just what, since I suspect there is a question about why you have so much IOWait time on your system, or poor performance? Regards, Daniel Footnotes: [1] It does, technically, spend a few in terms of submitting and completing the I/O before it wakes up the blocked process, and various I/O devices need babysitting, but the principal is sound. ;) Animal Logic http://www.animallogic.com Please think of the environment before printing this email.

[SLUG] tuning a maximum load
Hello I have a problem where I am running thirdparty software sporadically my machine(s) get into a state where they are responsive to pings but not ssh or a local console. I suspect that it is generating a very high load but there is now way to confirm what is going on. I am thinking of two things 1 enable Magic SysRq to hopefully get somthing out of it. 2 Is there a way to tune the way/algorithm the kernel uses so that under load it will kill off processes earlier or more aggresively under extreme load.

RE: [SLUG] [Fwd: Fwd: Re: Anyone listen to JJJ - MyDoom linked to Linux users]
Hello I listened to it in the car and found it quite good in its explanation of linux and it's relation to SCO. It actually painted Linux in a good light. Yes JJJ did get someone's opinion, and it was quoted as an opinion, that it was most definitely a linux user or some such and did say his name. Whether that's true or not JJJ did not accuse linux users nor talk of them badly, if anything they painted a good picture saying that we are the good guys/people and passionate about open source and the community. If anything it would be the guy that was quoted you should be complaining to. Yes the current status of the court case may not have been up to date or to the minute... Come on... these guys are reporters reporting to the masses. They did say allegedly and it is a fact that there is a court case going on or the last time I looked... Maybe it's changed since then.

RE: [SLUG] Help with a laptop please
John You may be better off looking for info on the chipsets rather than the whole notebook. So find some indepth techinal info on the laptop. The main downer is normally the video card. If your distro doesn't support it or it's variants getting the latest xfree86 source and compiling it normally works well. There are Linux drivers for some winmodems so all is not lost. do a google for them or search the archives.

RE: [SLUG] Testing if password is valid
Is this in Linux itself? (Do you want to check the passwd or shadow file?) What do you define as a valid password? Yes in Linux. Ok example, lets say there is a user on the system called kevin (in your honour ;-) and he has a password that is encrypted in the shadow file. Now this script is being run by someone who claims to be kevin, but I want to be sure, so I prompt them to keyin their password which I jam into a variable in the script, is there a system command that will allow me to check the password is valid? I.E the user kevin could logon to Linux with it. what about using somthing like sudo. It has this functionality allready. eg Set the script to only run as root and set sudo to allow kevin to run the script once authenticated.

RE: [SLUG] newbie to Linux
Hi Thirdly, I have a largish HDD, and rather than re-format the whole thing, if I could somehow 'create' a multiboot with Linux/Windoze over my existing system, it would be better. I've heard lots of different stuff, the upshot was that most say you can't, and one guy said you can, with Partition Magic. Any ideas? Fourth, if I CAN'T do #3 is it easy/possible to setup a new hard drive and boot between the two? Another option if you only want to dip your toe in the water is to use the REDHAT 7.1+ install cd. There is an option on install (I forget what its called that that creates a loopback filesystem. This creates your linux partions as files that sit on top of you windows file system. The performance is not as good and it means you have to boot from floppy but it may be a nice safe way to go Grant -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
RE: [SLUG] seeking Aust. GST accounting software under Linux
There is a little known Australian company that have financial software called Century Software. They have have clients in Australia, NZ, and SE Asia. It's a nice Graphical App that can run using X11, or Java, and it's also very scalable. They had a version called foxonlinux that was specially priced but only had the modules Cash book, Accounts Recievible, Accounts payable and General ledger. They have other modules like Project costing, Point of sale etc about 20+ They do not release the source but do give you support. It is compliant with NZ VAT and AUST GST.

RE: [SLUG] Sun optical mice
Hello I printed out the mouse mat, but the cursor doesn't move when I move the mouse. I used Sun's optical mice about 5-6 years ago, so I'm refering to technology from way back when. From memory the mouse mats were a grid on a shiny metal pad. They depended on these mats, and would not work on other surfaces. This is unlike the ones you can buy for your PC now. Perhaps I should mention that there's only one LED shining out the bottom. There are two holes in the bottom with LED-type devices in them. Only one shines and they're not close together. Is this faulty? Not sure... I know that it depends on the LED reflecting off the mat and detecting that, but I cant remember if there were two alight or one send and one detect. I think it ws two alight. Grant -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug
