[arch-general] How secure is wifi-menu
by h8h＠dev-nu11.de 02 Apr '15

02 Apr '15

hi I recently switched to a new laptop and therefore I copied all my wifi-configuration files (/etc/netctl) to the new one. Too bad that the wifi interface has changed (thanks to sysctl) and I wrote a small bash script, which should change the `interface` variable. By the way the script doesn't work very well, but I place it in the same folder with all the wifi-configuration files (/etc/netctl/) and I noticed that the tool `wifi-menu` is executing my script. I don't think this is a big vulnerability nor a bug, but if an attacker has the opportunity to place a bash file there, the system could be damaged by simple executing `wifi-menu`. Yes I know that the folder is not world / user writeable, but maybe some thoughts from the archlinux community? The reason for executing is sourceing all the files in /etc/netctl, maybe this could be improved by using eval and grep, see [1] Cheers Christian Homeyer H8H [1] https://bbs.archlinux.org/viewtopic.php?id=85726

[arch-general] git bug? (2.3.4-1)
by Magnus Therning 27 Mar '15

27 Mar '15

I thought I'd ask here before raising a ticket. Is anyone else seeing this behaviour with git 2.3.4-1: ~~~ [I] % git fetch ssh: Could not resolve hostname build01:: Name or service not known fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. ~~~ Downgrading to 2.3.3-1 "solves" it. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus $my_args = shift; system("gcc $my_args"); print "I prefer C\n"; -- Robert Dieterich's contribution to the 2004 Perl Haiku Contest, Haikus in Perl - 'Dishonerable Mention' winner

Hey everyone, since the upgrade to kernel 3.19 I'm having some trouble with my laptop: When booting, it occasionally either crashes while establishing an ibus connection or it floods the tty with some nouveau errors: nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ] Can someone help me fix this? Thanks in advance, Heiko

FYI After updating to this new version - there is an error: fatal: /usr/lib/postfix/postfix-script: No such file o Which is absolutely correct - that file does not exist. Downgrading back to 3.0.0-2 works around the issue. Gene

[arch-general] Can't reboot or shutdown my computer (cgroup: option or name mismatch)
by Janilson Andrade 17 Mar '15

17 Mar '15

Hi all. After months trying many things and after posting in arch forum[1] I am here asking if anyone could help me.Everytime I try to reboot or shutdown my computer, after turning everything off, my system hangs and display one of these messages below. a) cgroup : option or name mismatch, new: 0x0"", old: 0x4 "systemd" shutdown[1]: Failed to finalize file systems, ignoring b) A stop job is running for Daemon for power management (20s/1min 30s)I use Gnome 3, when I've changed to my DE to KDE the reboot options worked sometimes, but most of the times it didn't. After it stop working at all I've come back to Gnome, since I can't reboot my system no matter what I do. OBS: I know the cgroup message is just a warning to most of people, but for me it freezes my system and I can only turn the power off and on in order to reboot my computer, I really want some help of how can I at least search for the possible things that is causing this problem.Sorry for long e-mail.

[arch-general] Duplicated Trash folder in thunderbird

Hi My thunderbird now creates another Trash folder (checked via webmail), and the two trash folders are marked with the trash icon. I can't find a way to go back to a normal situation. Does anybody has the same problem ? I use thunderbird-beta-bin-all-localizations. Yamakaky
