[SOLVED] How to fsck+badblocks with systemd?

Before systemd I could boot into single mode, then "mount / -o remount,ro" and then "fsck.ext4 -c ...". Now I can't since it says / is in use and I can't remount as read-only. What do I do?

How to start dhclient with systemd at startup? [SOLVED]

I have eth0 connected to DHCP server and want to use dhclient instead of dhcpcd. How can I start dhclient with systemd? Is there something similar to
systemctl enable dhcpcd@eth0
Last edited by mpelikan (2012-12-18 13:43:28)

dhcpcd comes in package with completed systemd unit (/usr/lib/systemd/system/dhcpcd.service and /usr/lib/systemd/system/[email protected]) by package developer, but dhclient doesn't.
mpelikan, you should write your own systemd unit for dhclient for yourself using
1) dhcpcd units as example
2) wiki page https://wiki.archlinux.org/index.php/Sy … vice_files
3) man page for dhclient to get the right options
Also I'm sure I saw somewhere an example of dhclient unit but I can't find it now. Anyway, it was not working out-of-box in Arch.
I've done this previously but then I've realized disadvantages of dhclient (so I've removed it).
Firstly, I didn't like how it's working in daemon-mode after some testing.
Secondly, it depends on deprecated net-tools.
You should try dhcpcd. If it doesn't work, you can make it work by editing configuration files / kernel options (like switching off IPv6 if you think you have an issues with it) or adding some parameters.

[SOLVED] Disabling Bluetooth on boot with systemd

I'm having a nasty-won't-go-away problem with the disabling of the bluetooth module in my Thinkpad X200s.
Resorting to the old Arch way of disabling bluetooth on boot, I added this to my rc.local:
/bin/echo 0 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable
The thing is, this somehow made my boots hit'n'miss: kernel panics every two boots. As soon as I commented that line from my rc.local... no more kernel panics at boot.
I was still using an rc.conf just with daemons, and in troubleshooting the kernel panics got rid of it and used the systemd way of enabling/disabling services. My problem here is that the bluetooth service seems to be impossible to disable.
I first tried the good ol'
systemctl disable bluetooth.service
Which supposedly disabled bluetooth... but didn't. Even
systemctl stop bluetooth.service
Does not work.
Digging around the interwebs, I found that there are "stronger" ways to disable services with systemd, meaning "masking" services - basically links them to /dev/null
So, I tried masking the bugger...
systemctl mask bluetooth.service
Reboot and... the damn bluetooth is still enabled. Only way that works is to echo 0 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable... but I can't do it at boot with rc.local, otherwise I'll get the kernel panics again.
Any ideas?

It disables the bluetooth service which is very different from what your write to sysfs accomplishes. Don't you really just want to blacklist the bluetooth module? Your post is a bit hard to follow...

[SOLVED] How to start JACK with KDE 4? (and which JACK should I use?)

Hi again
I'm using KDE 4, and I've just installed JACK again, and since I can't find any decent documentation on this, I'm having a bit of a problem.
Currently I have jack from [extra] installed, rather than jack2. When I try starting jack as the ArchWiki suggests, i.e. by typing "jackd -d alsa", I get the following error:
$ jackd -d alsa
jackd 0.120.1
Copyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn and others.

the playback device "hw:0" is already in use. Please stop the application using it and run JACK again

I've also tried jack2 from [community], and after starting it with "jack_control start", I get this...
$ jack_control start
--- start
DBus exception: org.jackaudio.Error.Generic: Failed to start server
So how do I start it? I'm guessing jack doesn't want to start because some other KDE application grabbed alsa before jackd (but I've been wrong before), and I don't have the slightest idea what jack2 is about with that "generic" error. If anyone would help me shed some light on this, I'd appreciate it a lot.
Thanks in advance!

@schivmeister thanks that one worked
Yes, it was knotify4. So now this part works. I've switched to jack2 and it works flawlessly when starting it with jackd
So this part is solved... now, would you be so kind (if you know) as to point me to some tutorials or howtos (or proper documentation, cos I can't find much of that either) on how to connect various ALSA channels with JACK?
Basically, I want to route my PCM channel and the Mic channel into Capture 1 (or one to Capture 1 and other to Capture 2), since my Intel HDA audio card doesn't have the "Mix" or "What-U-Hear" or whatever as an available capture source. Any leads on that? (or do I have to open another thread for it?)
TIA

How to fsck /usr with LVM?

Wasn't sure where to post this:
I just applied a pile of updates to my Arch+MythTV PVR. Not necessarily related to my problem, but this update included the replacement for mtab. On reboot, I get dumped into single-user because /usr is dirty. Dirty dirty /usr. Of course, I cannot fsck it because I cannot unmount it. I'm using LVM: two 2TB drives mirrored, two VGs defined (rootvg and datavg). /usr is it's own filesystem within rootvg.
Any suggestions on how to get this fixed? I assume I'll have to boot from a liveCD. Preferably something that will recognize the LVM stuff at boot and take care of all that mess. Recommendations?

How to replace Consolekit with systemd-loginctl

Is systemd's new multiseat ready to replace consolekit?
And if, how can I achieve that?
My Background:
- I use systemd as my init system
- login into a getty
- which create a new X session with startx through a login script
I have had a hard time before I had the right setup to supervise everything with *ck-launch-session* and *dbus-launch* (order matters).
And sometimes without a reason, something breaks and I'm not allowed to mount USB drives or shutdown as a user without a reboot.
Last edited by Mic92 (2012-06-01 13:36:59)

I do have a session:
┌─[jente @ lappy ~] 21:48:14
└─■ loginctl
SESSION UID USER SEAT
1 1000 jente seat0
1 sessions listed.
I start Udiskie through .xinitrc, like so:
if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
eval `dbus-launch --sh-syntax --exit-with-session`
fi
exec bash -c "udiskie & $HOME/.bin/dwm_start"
With .bin/dwm_start:
#!/bin/bash
while true; do
dwm >/dev/null 2>&1
done
EDIT: Here's udiskie's output when I plug in my external HD:
attempting to mount device /org/freedesktop/UDisks/devices/sdb2 (ext4:[])
failed to mount device /org/freedesktop/UDisks/devices/sdb2: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized

failed to mount device /org/freedesktop/UDisks/devices/sdb1: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized
EDIT2:
Changing my .xinitrc to the following didn't help either:
udiskie &
exec $HOME/.bin/dwm_start
Also, I found out I have to enter my root password to shutdown/reboot, whereas I didn't have to before.

[SOLVED] Netcfg.service not starting with systemd

I have net-auto-wireless.service enabled and working, but when I try to start netcfg.service, it gives the error:
Job for netcfg.service failed. See 'systemctl status netcfg.service' and 'journalctl' for details.
"systemctl status netcfg.service" gives me:
netcfg.service - Netcfg multi-profile daemon
Loaded: loaded (/usr/lib/systemd/system/netcfg.service; enabled)

And the output of "journalctl" is:

Am I missing something in setting it up? I followed the netcfg wiki as closely as I could.

Good call, I changed it from "last", to the profile I use in /etc/network.d that net-auto-wireless autoconnects to. It failed for a different reason after changing the NETWORKS in /etc/conf.d/netcfg, because net-auto-wireless was still running.
But it works now, thanks for the help!
I wanted to use netcfg instead of net-auto-wireless because I was unable to find a suitable way to connect to available networks that is non-graphical, and I felt like giving netcfg a try and seeing if it's any easier than running "systemctl restart net-auto-wireless.service" every time I want to reconnect.
Although my question for this thread is solved, is there any way to have netcfg autoconnect to profiles once I am within range?

[SOLVED]How to install packages with the -U option? PGP error.

I have to downgrade some packages (linux package due to ath5k problem), but pacman won't allow me because of the signatures.
I downloaded the packages i need from here http://schlunix.org/archlinux/.
These packages are safe to install? How can i bypass the signature check, if these packages are safe to install?
Thanks.
Last edited by Hyugga (2012-04-19 19:46:23)

If you have a pgp key, you can sign the packages with your own key. You can do this by editing /etc/makepkg.conf, adding your key to the GPGKEY="" section and enabling the sign option in the BUILDENV section. When building the package, it'll then be signed with your personal key. Afterwards import your key in pacman (pacman-key -r <yourkey>), assign the proper trust level and you're good to go.
A workaround is to temporarily set "SigLevel = Never" in your /etc/pacman.conf (and hence disabling keysigning).
EDIT: I just bothered to actually check your link and you'll be installing prebuilt binaries, so my first explanation doesn't apply there (you won't be building anything). So just setting SigLevel to Optional or Never (temporarily) should do.

[SOLVED]How do I deal with non-unicode filenames inside archives?

I often get archives from Japanese Windows users with file names encoded in one of the myriad of Japanese character sets. Windows is pretty good about converting the filename to unicode before passing it on to any program or computer that expects it. However, it won't touch the filenames of things inside the archive for obvious reasons. Any way to make, say, unzip or 7z convert the filenames to unicode as they're extracted? At the moment I run Windows in Virtualbox and connect back to a shared folder and let Windows do the unzipping.

I have written a script, which start my wlan.

modprobe iwlagn
ifconfig wlan0 up

case "$1" in
start) wlan_start ;;
stop) wlan_stop ;;

If I run it from a console (sudo /usr/local/bin/wlan start) the wpa_gui pops up.
I have installed it into the handler.sh from acpi. The script is correctly executed, if fn+f5 is pressed, but wpa_gui does not pop up.
What should I change, that it the gui pops up whith fn+f5?
Edit:
The problem was, that I forgot the access restriction of X.
Adding following code helps:
export DISPLAY=:0.0
export XAUTHORITY=/root/.Xauthority
Remark: /root/.Xauthority is a link to the file of the notebook user.

6. Restart Pulseaudio daemon on Arch64 and Run "paplay" on Arch32 to test.

[Solved] How to Install i3 with xorg

HI guys,
I am trying to figure out if it is possible to install i3 having only xorg installed.
I followed the installation guide for arch-linux and I installed X-org
pacman -S xorg-server xorg-server-utils xorg-xinit
I have installed and configured i3 as explained here: https://wiki.archlinux.org/index.php/i3
Despite my efforts I am not able to make it run. Could you please explain me:
1) what are the minimum requirements to run i3 in terms of desktop environment?
2) have I missed something in the installation process?
Thank you for your help!
Last edited by pappix (2014-03-17 23:12:00)

Hi Karol,
thanks for the fast reply! I kept trying and at the end I was able to start i3 by running
xinit i3
It turned out that was failing to execute i3 because i set ~/.xinitrc in the following way:
exec i3 -V >> ~/.i3/i3log 2>&1
and since i3 was never run before there was no ~/.i3 directory. During the first execution of i3 it asks for the creation of such directory, thus after the 1st execution it is possible to write the full command line in /.xinitrc, but if you do that before, you have to create the directory first.
BTW now I am running i3 with XORG alone, it' s ugly but I am going to work on it.
Thanks for the help though, I hope this post will help someone else

How to configure BIND (chroot) with systemd

Hello,
I'm following guide https://wiki.archlinux.org/index.php/BIND_(chroot). In the end there is only said how to enable service in sysvinit environment. Could someone please tell me how to do this with systemd?
Thanks

@toogy: what do you mean exactly by creating a systemd service?
EDIT: for example, I've this one (in /etc/systemd/system/mynamed.service)
[Unit]
Description=Internet domain name server
After=network.target
[Service]
ExecStart=/usr/bin/named -f -u named -4
ExecReload=/usr/bin/rndc reload
ExecStop=/usr/bin/rndc stop
[Install]
WantedBy=multi-user.target
And according to 'man named', you can use the '-t' parameter if you want named to run in a chroot (I've never tried it):
-t directory: Chroot to directory after processing the command line arguments, but before reading the configuration file.
Warning: This option should be used in conjunction with the -u option, as chrooting a process running as root doesn't enhance security on most systems; the way chroot(2) is defined allows a process with root privileges to escape a chroot jail.
