[SLUG] mount LVM from Ubuntu live CD
Can it be done? All the instructions I've found on the net require installation of lvm2 - not sure this is practical on Live CD, even if it was connected to the net, which it isn't. The computer belongs to a club (I haven't had direct access to it yet) - the administrator has vanished and taken the password with him and the drive is now at least partly corrupted and won't boot without a root password. fstab tells me it's LVM.

I don't have either but would get one if it worked. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Linux Software Review Day
Its Software Review Day today, So if your reading this make sure you have posted your review. So for my review ill be reviewing a program called xwinwrap, What is this program you say??? well it enables you to have a animated desktop :-O , yes its true, you can animate your desktop and its easy. I'm running Ubuntu so my instructions are as is. Open up your terminal and us these commands to download and install: sudo apt-get install build-essential libx11-dev x11proto-xext-dev libxrender-dev libxext-dev cvs * cvs -d :pserver:anon...@cvs.freedesktop.org:/cvs/xapps co xwinwrap * * cd xwinwrap * * make * * sudo cp xwinwrap /usr/bin So hopefully you have successfully downloaded and compiled and installed. To the fun part know, with the next example you will use the glmatrix screen saver as your desktop. * nice -n 15 xwinwrap -ni -o 0.20 -fs -s -sp -st -b -nf -- /usr/lib/xscreensaver/glmatrix -root -window-id WID So if you look at your desktop you should have the matrix screen saver streaming over top of your desktop, how cool :-! , you may notice that its a bit transparent well you can change that if you like plus may other things about the behaviour by changing the command switches. xwinwrap [-g] [-ni] [-argb] [-fs] [-s] [-st] [-sp] [-a] [-b] [-nf] [-fl] [-o OPACITY] -- COMMAND ARG1... -g geometry -ni no input -argb argb, Alpha, Red, Green, Blues -fs fullscreen -s sticky -st skip taskbar -sp skip pager -a above -b below -nf noFocus -o opacity=# Between 0 and 1 Your not limited to just the glmatrix screen saver, any screeen saver in the /usr/lib/xscreensaver directory should work a treat.

[SLUG] removing samba
I needed to do some file sharing recently and now that the task is finished so I want to remove the Samba service. I'm using Ubuntu 9.10. in Synaptic search: samba shows that the following items are installed; samba samba-common samba-common-bin smbclient libpam-smbpass libsmbclient libwbclient0 nautilus-share python-smbc When I mark samba for removal no other files on this list are marked. So is just marking samba for removal sufficient to stop this service from starting at boot... and I don't want to keep files that only rely on samba alone as they'll be superfluous. But when I select samba-common to be removed, Synaptic notifies me of a list of other files that it will also remove with samba-common - one of them being ubuntu-desktop. I'm not so sure that I want ubuntu-desktop removed! advice/suggestions/help are welcome :) thanks...

Re: [SLUG] removing samba
If baffles me as to why it's so difficult to stop a service on boot in ubuntu but read this post: http://ubuntuforums.org/showthread.php?t=1341947 I also don't see why it's been made hard to pull samba out, maybe someone more ubuntu friendly can explain how to remove the program it's self but for now if the service is off it shouldn't bother you. You could also just try removing entries in /etc/samba/smb.conf if u can't stop the service On 19/02/2010, at 8:11, meryl gnu...@aromagardens.com.au wrote: I needed to do some file sharing recently and now that the task is finished so I want to remove the Samba service.

Re: [SLUG] removing samba
- Original Message - From: meryl Sent: Friday, 19 February, 2010 8:11:53 AM I needed to do some file sharing recently and now that the task is finished so I want to remove the Samba service. I'm using Ubuntu 9.10. in Synaptic search: samba shows that the following items are installed; samba samba-common samba-common-bin smbclient libpam-smbpass libsmbclient libwbclient0 nautilus-share python-smbc Hi Meryl, If you jump on the command line and type apt-cache show samba then scroll down you'll see this (this was on a Ubuntu 8.04 system - YMMV): Currently, the Samba Debian packages consist of the following: . samba - LanManager-like file and printer server for Unix. samba-common - Samba common files used by both the server and the client. smbclient - LanManager-like simple client for Unix. swat - Samba Web Administration Tool samba-doc - Samba documentation. samba-doc-pdf - Samba documentation in PDF format. smbfs - Mount and umount commands for the smbfs (kernels 2.2.x and above). libpam-smbpass - pluggable authentication module for SMB/CIFS password database libsmbclient - Shared library that allows applications to talk to SMB/CIFS servers libsmbclient-dev - libsmbclient shared libraries winbind - Service to resolve user and group information from Windows NT servers . It is possible to install a subset of these packages depending on your particular needs. For example, to access other SMB/CIFS servers you should only need the smbclient and samba-common packages. So with the exception of the nautilus/python bindings Synaptic seems to correspond to the list. Notice that last line? ;) Read on... When I mark samba for removal no other files on this list are marked. So is just marking samba for removal sufficient to stop this service from starting at boot... and I don't want to keep files that only rely on samba alone as they'll be superfluous. Keep in mind there are 2 halves to the Samaba packages: server components and client components (see the description next to samba-common?) with some common bits they both share. You probably only want to get rid of the server components. But when I select samba-common to be removed, Synaptic notifies me of a list of other files that it will also remove with samba-common - one of them being ubuntu-desktop. I'm not so sure that I want ubuntu-desktop removed! Don't sweat the ubuntu-desktop package. It's not a real package, it's a meta-package which depends on all the components for an interactive desktop etc. If you go to the command line (again...sorry) and type apt-cache show ubunut-desktop you'll notice in the Depends section it relies on smbclient. So if you remove the smbclient package the package manager must remove the ubuntu-desktop meta-package to maintain dependancies. HOWEVER, removing a meta-package DOES NOT remove the packages it depends on :) So it's safe. Getting back to your original query, you should be able to remove: samba swat samba-doc samba-doc-pdf libpam-smbpass winbind Just leave the smbclient package and ubuntu-desktop should be fine. Worst case scenario, hose ALL the samba stuff (which will take out ubuntu-desktop as colateral) then simply re-install ubuntu-desktop. This will ensure you only get the bits of samba required to satisfy ubuntu-desktop when you re-install it. Not perfect, but it is simple. Have fun! -- James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I'm not so sure that I want ubuntu-desktop removed! Ubuntu-desktop is a meta-package, a package that contains no files itself, but depends on a bunch of other things that would be useful to have if you are running an ubuntu desktop machine. However, unless you really know what you are doing, you should probably keep ubuntu-desktop installed.

At the command line: sudo apt-get autoremove The clean up 'mostly' just works but sometimes dependent libraries will be left lying around. Also in synaptic, check for a section 'Not Installed (residual config). If you want you can flag these for complete removal, cleaning up more package information.

For 40-100 users 2x SATA drives in software raid 1 should be sufficient. 2) Reliability Sure software raid 1 will give you that. Make sure you install grub on both drives so you can boot off either in case one dies. Also make sure you monitor for failures. 3) Ease of maintenance. Document the setup. And keep the docs current. Anyone care to take a punt at a layout? This really depends on your requirement for how much email you want to store on the system, duration of logs etc. Will the system be doing anything else? If so the layout might change. I would personally use something along the lines of the following. /boot (md0 100mb) Create another raid 1 array md1 fully allocate this to a PV. I usually call the PV the hostname of the machine. So if I need to access the disk/s from another system I know which system the disk is from. / - LV called root 3-4GB /var/spool/mail - LV called mailspool 1-5 GB (I am assuming I would be storing mail elsewhere such as /home/user/Maildir) /var/log - LV called logs, 5 GB to start with. I'd also have mail logs compressed and rotated daily. Archive as long as you need too. /home - LV called home, 50GB to what ever you deem required for user email storage needs. I'd have users storing mail in their home directories so they can use IMAP and leave mail on the server. If I was doing anything with a database, I would have a dedicated LV for /var/lib/mysql or /var/lib/pgsql. This would allow me to snapshot those volumes for backups etc. Thanks Paul, you just confirmed some of what I was thinking - it's always nice to get a warm feeling though :) The machine currently uses /home/%U%/Maildir for mail storage as you suggested.

[SLUG] Tutorial Friday week
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi All, First some info: I have an old Acer Travelmate 529ATX with 512Mb RAM(its max). It has a P111 (coppermine) about 900 MHz and a 120GB HDD. At the moment I am running PCLinuxOS and dual booting with XP. I have given Linux a 10GB file system drive and a 60GB home drive with a 1GB swap. Now question or two: 1. Is this notebook good enough for the tutorial? 2. If it is, can anyone recommend a distribution/desktop/setup that would be considerably faster than PCLinuxOS/Gnome? 3. If this notebook is too low in spec, what would you recommend as an inexpensive replacement for the tutorial?

[SLUG] Re: Netbooks .... Again
Acer One Aspire. Similar thoughts to the two Peters (C and H) S'very light and easy to carry around. I like the big gap between the screen and the body (the hinges create this). Very nice to hook your fingers through when you carry it around. A nice secure hand hold indeed. Screen is sharp. Installed Ubuntu NBR - I REALLY like their GUI. Very functional for small screen. Build quality is great, keyboard is very good for its size. You get used to it really quickly. I even came to like the mouse keys being on either side of touchpad. Sound is good too. On occasions the SSD runs slow and there can be a pause in activity. Shut down can be slow sometimes (but I think this is probably the related to the SSD speed issues). One other thing is it connects via WiFi really quickly. Can't say the battery life is great, but I think the new NBRs have improved on that and it has the small battery. The one with more cells would certainly improve that. Camera works well with Skype. We had a party during which we Skyped a relative in the USA. We passed the netbook around and he was able to speak to and see everyone there and join in with the kids blowing out the candles. Good stuff. Then I took a vol redundancy and bought a Lenovo X200...weighs not much more than the Acer (costs a lot more though) and the Acer has become redundant. Anyone want to buy one? :)) Regards, Patrick (NB.

Re: [SLUG] mount LVM from Ubuntu live CD
david da...@kenpro.com.au writes: Can it be done? Sure. All the instructions I've found on the net require installation of lvm2 - not sure this is practical on Live CD, even if it was connected to the net, which it isn't. ...it is practical, and works, but you do need a net connection. IIRC, the live *DVD* includes a huge pool of standard packages which you can use locally, or you could download the required .deb files to a USB key or something and manually install them. Sorry. The computer belongs to a club (I haven't had direct access to it yet) - the administrator has vanished and taken the password with him and the drive is now at least partly corrupted and won't boot without a root password. Wanna know a secret: your Linux box is almost certainly trivial to break. Try booting the kernel with 'init=/bin/bash' on the command line, and then: ] mount / -o remount,rw ] passwd root # ...and give it a good password ] mount / -o remount,or ] sync; sync; sync # wait thirty seconds, because paranoia never hurts ] sync; sync; sync; reboot That should get you past the problem, at least as far as the next issue. You can also run a fsck on the root volume or whatever at that shell. Just be aware that you don't get a lot of nice things like, oh, some of the flush on shutdown behaviour that you do in a normal boot. :) Daniel -- ✣ Daniel Pittman✉ dan...@rimspace.net☎ +61 401 155 707 ♽ made with 100 percent post-consumer electrons -- 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] RAID and LVM
Slower, though ... is a bit of a strange claim. Not because it is false, but because the answer is complex: you can, for example, double read speed and halve write speed, using a two disk RAID 1 array ... in the ideal case. I must say I'm curious about this, because I have always assumed that for a RAID 1 the write speed would be roughly the same as a single disk, not halved.. my reasoning being that both writes would occur in parallel, as with the reads.. the difference of course is that the 2 reads in parallel each transfer half the data, but the 2 writes transfers all the data each sure, you may have a little bit of overhead - issuing 2 IO instructions instead of 1, or in the case of a setup where both disks share the same bus (which is not the ideal setup) there would be contention on this bus, but halved? Is it really the case? If this is true, I guess the reason would be that the same data travels over the same bus twice before the operation can be said to be completed, therefore halving your write speed. But then this holds true for the read as well, so that despite issuing an instruction to 2 different disks, each with half the data requested, then you will meet the same contention and the data will get to you with the same speed as 1 disk.. so, if this is right, then RAID 1 compared to a single disk would be something like 1. 2 disks on 2 buses = (approx) half read time, same write time 2. 2 disks on 1 bus = (approx) same read time, double write time I honestly don't know if this is the case or not, I've certaintly never measured it and it may be implementation specific, but if not I'd really like to be shown where this is wrong.. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

How easy was it to get your chosen Linux up and running (this is of course relative to the person - Me. I'm no genius, but I can figure it out if I have to) Everything worked out of the box with UNR 9.10. I had problems with my wireless card (it was flaky after hibernation and suspends) but I replaced it with another one out of another computer (seems to be almost the same card, used same kernel modules, etc) and its been good since. 6. How has the build quality stood up Nice, the EeePC S101 is one of the nicer EeePC netbooks 7. What sorts of quirks have you discovered I know Marghanita was big on the Kogans. How many others bought one of those? Prob with Kogan is apparently sold out till April.
