[arch-general] net-snmp conflict files on upgrade
by Leonidas Spyropoulos 25 Oct '12

25 Oct '12

When I tried today to upgrade the system with: pacman -Suyy I got conflicts on net-snmp package. I installed everything except that and tried again with no results, is it safe to --force it? Anyone had that also? pacman log: http://pastie.org/5106091 -- Caution: breathing may be hazardous to your health. #include <stdio.h> int main(){printf("%s","\x4c\x65\x6f\x6e\x69\x64\x61\x73");}

[arch-general] Exiting wpa_supplicant
by Nelson Marambio 24 Oct '12

24 Oct '12

Dear list, I try to write a small shellscript that (dis-)connects me with / from the WLAN of my university. I use wpa_supplicant in combination with the -B switch to establish the connection. After a pause of 10 seconds I pull an IP address by calling dhcpcd. My question (in context of the wlan-disconnect-script): how can I exit wpa_supplicant if it runs in the background ? Up to now it's done by "sudo killall wpa_supplicant" but I guess it's not the best way. Kind regards, Nelson.

[arch-general] [linux] ext4 data corruption bug
by Christian Hesse 24 Oct '12

Hello everybody, a thread has been started on lkml discussing a serious ext4 data corruption bug in latest stable kernels. [0] Looks like the root cause is not really clear so far. Reverting the commit in question should fix the problem though.

[arch-general] autofs issue after location change
by Genes MailLists 23 Oct '12

23 Oct '12

I had used one of my autofs mounts last night on my laptop. This morning I put it to sleep and moved to a different location where that nfs server is not available. I am fully updated to testing repo (as of last night anyway :-) ). (i) pacman hung (tho I understand from https://projects.archlinux.org/pacman.git/commit/?id=e183522e3168c4a31103b3… that this may be fixed .. tho that was quite quite some time back so maybe something else is happening. (ii) Alerted by the hang - I tried to restart autofs via systemctl restart autofs Perhaps I didn't wait long enough - but this did not complete. (iii) So I rebooted pc. The shutdown hung after systemd reported [ok] for shutting off remote file systems. Again I only waited a few minutes - perhaps it would have timed out after sufficiently long - but how long? (iii) was especially surpising to me - I thought systemd would kill the daemon sooner. Can anyone share What is the right way of dealing with this 'dead autofs mount' issue? Thanks gene/

[arch-general] Leafnode and Systemd
by Whiskers 23 Oct '12

23 Oct '12

Leafnode-2 <http://www.dt.e-technik.uni-dortmund.de/~ma/leafnode/beta/> is a local caching proxy nntp server. It isn't among Arch's packages, but I have been using it for some years on another distro (Mandrake/Mandriva). Systemd launches xinetd on start-up: $ cat /usr/lib/systemd/system/xinetd.service [Unit] Description=A secure replacement for inetd After=network.target [Service] ExecStart=/usr/sbin/xinetd -dontfork ExecReload=/bin/kill -HUP $MAINPID [Install] WantedBy=multi-user.target $ And xinetd has this file for Leafnode: $ cat /etc/xinetd.d/nntp service Leafnode { flags = NAMEINARGS NOLIBWRAP per_source = 3 port = 119 socket_type = stream protocol = tcp user = news server = /usr/sbin/tcpd server_args = /usr/local/sbin/leafnode type = UNLISTED wait = no instances = 7 only_from = 127.0.0.1 } (actually generated using webmin, but in accord with the instructions in the README and INSTALL files in the Leafnode tarball). But this doesn't allow any user to access Leafnode; I suspect this is because /usr/sbin/tcpd doesn't exist (being a part of tcp-wrappers which Arch no longer has). (I can run the Leafnode components fetchnews and texpire as root; but attempts to connect to the local server result in "connection refused"). There are no daemons launched from /etc/rc.conf. I have installed ufw as a substitute for tcp-wrappers and created this file: $ cat /etc/ufw/applications.d/ufw-newsserver [Leafnode] title=Leafnode description=NNTP caching proxy server ports=119/tcp $ and have these rules in force, at least one of which should allow local access to leafnode, I think: # ufw status Status: active To Action From -- ------ ---- Anywhere ALLOW 127.0.0.1 newsserver ALLOW 127.0.0.1 127.0.0.1 119/tcp ALLOW 127.0.0.1 Leafnode ALLOW 127.0.0.1 Rather than install tcp-wrappers on my Arch system, I'd like to use whatever the proper "server" is nowadays instead of /usr/sbin/tcpd - but what is it? Or is there something other than xinetd that works as a 'super server' with systemd? I've only been using Arch for a few months, and it's a bit of a challenge getting used to the Arch Way - particularly while it's changing over to systemd etc - so please be patient with me if I've missed something simple or made a newbie mistake! -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~

[arch-general] Multiple Wired Profiles with Systemd
by Alper Kanat 23 Oct '12

23 Oct '12

Hey All, I just switched to systemd. I work on an Arch Linux Virtualbox VM which runs on Mac OS X. I assigned 3 NIC's to that VM and 2 of them have ethernet-dhcp profiles defined and set in /etc/conf.d/netcfg to be started at boot. $ cat /etc/conf.d/netcfg NETWORKS=(public local) However on boot, I see messages like the following: Oct 23 15:18:52 starbucks netcfg-daemon[168]: :: public up Interface eth0 does not exist Oct 23 15:18:52 starbucks netcfg-daemon[168]: :: local up Interface eth1 does not exist Oct 23 15:18:52 starbucks netcfg-daemon[168]: [fail] Oct 23 15:18:52 starbucks systemd[1]: netcfg.service: main process exited, code=exited, status=1 Oct 23 15:18:52 starbucks systemd[1]: Failed to start Netcfg multi-profile daemon.

Oct 23 15:18:52 starbucks systemd[1]: Starting Apache Web Server... Checking the interfaces via ifconfig shows that none of them are up. If I start netcfg service manually, both interfaces will be up successfully: $ sudo systemctl start netcfg $ sudo systemctl status netcfg netcfg.service - Netcfg multi-profile daemon Loaded: loaded (/usr/lib/systemd/system/netcfg.service; enabled) Active: active (exited) since Tue, 23 Oct 2012 15:33:02 +0300; 18min ago Process: 354 ExecStart=/usr/bin/netcfg-daemon start (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/netcfg.service ├ 408 dhcpcd -qL -t 60 eth0 └ 474 dhcpcd -qL -t 60 eth1 I checked the forum to see if there are any solutions. Tried multi-user services by enabling with the following commands resulted as the same: $ sudo systemctl enable netcfg@public $ sudo systemctl enable netcfg@local Found out some threads on the forum that suggests to copy service definitions and overwrite them but that didn't look like a solution to me. All tickets created at flyspray was about 1 wireless - 1 wired setups. Some of them are closed, marked as "Not a bug". Anyone having the same issue? Any suggestions? Currently I enabled netcfg.service. Sometimes all NICs are disabled, sometimes both are enabled. Mostly however only 1 NIC (the first one) is up. --- Quis custodiet ipsos custodes?

[arch-general] Modify installed package version
by gt 23 Oct '12

23 Oct '12

Hey guys is there a way to modify an installed package's version using pacman, instead of upgrading the package. That is, only change the version in the database, but don't actually upgrade a package. Alternatively can I rename the package directory inside /var/lib/pacman/local/ and %VERSION% string inside the desc file to achieve the same?

Hi All, I've just switched to systemd from initscript and I can't resolve an issue: fancontrol fails to run at boot time, but it works properly when manually started. Logs: UNIT LOAD ACTIVE SUB JOB DESCRIPTION colord.service loaded failed failed Manage, Install and Generate Color Profiles fancontrol.service loaded failed failed Fan control daemon # systemctl status fancontrol fancontrol.service - Fan control daemon Loaded: loaded (/etc/systemd/system/fancontrol.service; enabled) Active: failed (Result: exit-code) since Tue, 23 Oct 2012 07:23:42 +0200; 4min 53s ago Process: 434 ExecStart=/usr/sbin/fancontrol (code=exited, status=1/FAILURE) CGroup: name=systemd:/system/fancontrol.service Oct 23 07:23:51 arch fancontrol[434]: Controls hwmon1/device/fan2_input Oct 23 07:23:51 arch fancontrol[434]: MINTEMP=35 Oct 23 07:23:51 arch fancontrol[434]: MAXTEMP=45 Oct 23 07:23:51 arch fancontrol[434]: MINSTART=155 Oct 23 07:23:51 arch fancontrol[434]: MINSTOP=160 Oct 23 07:23:51 arch fancontrol[434]: MINPWM=155 Oct 23 07:23:51 arch fancontrol[434]: MAXPWM=210 Oct 23 07:23:51 arch fancontrol[434]: Device path of hwmon1 has changed Oct 23 07:23:51 arch fancontrol[434]: Device name of hwmon1 has changed Oct 23 07:23:51 arch fancontrol[434]: Configuration appears to be outdated, please run pwmconfig again I thought it is a timing issue, so I tweaked fancontrol.service, but didn't helped: # cat /etc/systemd/system/fancontrol.service .include /usr/lib/systemd/system/fancontrol.service [Unit] Requires=sensord.service After=sensord.service Any advice?
