Linux Containers - setup script?
by Philip Rhoades 01 Mar '11

01 Mar '11

People, I would like to set up lxc on Fedora 14 x86_64 for sandboxing and the closest thing I can find to a simple setup script is this: http://blog.kagesenshi.org/2010/03/howto-linux-container-lxc-on-fedora-12.h… which had a few bugs in it but after fixing them I still couldn't create a container (I posted a comment to the author on his blog). Does anyone know of some Fedora specific docs to get a minimal container going with a minimal amount of hand editing of configuration files etc? Thanks, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil(a)pricom.com.au

fc8 upgrade
by Jorgen Lundman 01 Mar '11

01 Mar '11

Hello list, Senior unix admin, but relatively fresh Linux admin. I run a fc8 box only for cross-compiling, as so many toolchains come pre-compiled for it. However, today I found the need to finally upgrade. This is an account of what I went through, and not just meant as a bitch session. I do not care about the OS, but it would be easier if all my toolchain installs and home directory contents remained. I have a tiny /boot and the rest on a lv / system, setup by a colleague. This all runs on xen, but that is not really part of this email. First I tried to use preupgrade, and I went through all the yum tasks to ensure I have the latest version of it and so on. Then I ran preupgrade, I went straight for fc14. I was told that my /boot was too small. Of course it is! Still, it did say something about downloading it after reboot. Plus one for fc there. Rebooting and it gives some obscure error about not finding previous system. Eh? Googling and crap, I finally find out how to get at the anaconda logs (it could have been mentioned by anaconda i think, instead of just 'error, click here to reboot') In the end it said something about fc8 can not be upgraded. I still do not really know why, but google suggests I can not skip versions, I need to go to 9 first. preupgraded only lists 10 to 14. I try 10 anyway. No difference at all. Bugger. Right, so I download the fc14 ISO and try to do a install over the old OS, hoping to keep data. The installer does have an option to keep things, the second to last option, before custom. It just notifies me that there are no places to install to, sorry. I use custom, which at least gives me some clues. Apparently I can not install to a ext3 filesystem. This seems a really bad decision by someone. Essentially, it is just untaring files on an existing fs. To force a certain version seems really backwards. I google for how to convert ext3 to ext4, and go through that. 2 hours later I am ready to try again. I return back to the installer, the 4th option still does not work, so i go through custom. I manage to convince it to use my / and /boot. It installs, I reboot. No warnings about losing data, so I feel confident here. Upon reboot it has no settings for network, ssh etc. So I go through the GUI to set network (I guess I am supposed to use GUI, even though I prefer to reach for ifconfig). I look for a way to start SSH, and there do not appear to be any. Google said to use Administration/Services. But that does not exists. Huh, I actually have to start a shell to run /sbin/services sshd start. Minus one there. Only to find that port 22 does not answer. I go through the usual checks to make sure it is running, and connects locally. I start the firewall GUI to confirm that port 22 is open, I even try without firewall. Still, no connection. How strange. there is a cryptic message about iptables? I don't have services so I can not check using the GUI, so again I am forced to use shell to disable it. Finally I can login. minus one again. Only to find everything has been wiped. Boo. It was a major hassle for me, I feel sorry for fresh people trying fc14 for the first time. I feel there is room to make some improvements. Anyway, I will zfs rollback to my fc8 and install something else. good luck, -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

OK, I blew it. I did not see FC15 in the subject. For I know dconf works well in FC15.

internet apps don't connect in FC14
by Jim Philips 01 Mar '11

01 Mar '11

I installed FC14 today on my laptop. I can connect to the Internet and download software. I can also ping sites out on the Internet from the command line. However, the browser refuses to load any pages and Evolution won't connect to a mail server. I tried turning off the firewall altogether and this made no difference. Any ideas on what the issue could be?

Fedora 14 - can't change pointer theme
by Neil Bird 01 Mar '11

01 Mar '11

I updated from Fedora 12 to Fedora 14 over the weekend, and now I can't change my pointer theme. I'm stuck using dmz-aa. The pointer preferences still show my custom pointer choice, it's just not being used. Well, mostly. Within Firefox and Thunderbird windows, my custom pointer is showing up. But window borders, the desktop and most apps only show the dmz-aa pointer. I can't find a ref. to dmx under ~/.gconf (but I can find my custom pointer selection: /desktop/gnome/peripherals/mouse/cursor_theme I think). Any ideas where to look? I've seen mention of this elsewhere, but only WRT compiz (I use openbox), and it involved changing the system default, which I don't want to have to do. -- [neil@fnx ~]# rm -f .signature [neil@fnx ~]# ls -l .signature ls: .signature: No such file or directory [neil@fnx ~]# exit

random crashes
by Andras Simon 01 Mar '11

01 Mar '11

My desktop machine started having random crashes last summer when I installed Fedora 13 (x86_64) on it. Now I upgraded to Fedora 14, and this has only got worse: before, uptimes could be anything between 3 minutes and a month, now it's a few hours at most. I never found anything interesting in the logs. When running without X, during a crash I saw a message on the console mentioning mcelog, so I installed and used it as a daemon, and also via /sys/devices/system/machinecheck/machinecheck0/trigger as described here: http://www.kernel.org/pub/linux/utils/cpu/mce/README But it didn't report anything. I checked temperatures with sensors: nothing. Ran memtest86+ for hours: the same. Is there something else that I should check? Andras

k3b dvd burn problems with growisofs
by Brian Millett 28 Feb '11

28 Feb '11

My system: fedora 14, dell e6500, TSSTcorp DVD +-RW TS-U633F With the default k3b that now uses growisofs to burn a dvd, it fails at 49% every time. Downloaded the k3b-2.0.2-2.fc14.src.rpm, disabled the patch51 which changes wodim to growisofs, recompiled and now I can burn a DVD iso image. -- Brian Millett - [ Garibaldi (re: spacing), "Revelations"] "They put you in an airlock, seal it, and then open the space door.
