Package: wpasupplicant
Version: 0.6.9-3
Severity: important
--- Please enter the report below this line. ---
Roaming with wpa_supplicant does not work, ifup/down does not work together
with wpa_supplicant, calling wpa_supplicant directly gives errors.
Details:
My /etc/network/intefaces contains:
iface ath0 inet manual
wpa-roam /etc/wpa_supplicant.conf
When starting an interface with
r...@vulpecula:/etc# ifup ath0
the script replies with
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return
code 1
two process have been created:
u...@host:# ps aux | grep wpa
root 12476 0.0 0.1 4856 856 ? Ss 23:09 0:00
/sbin/wpa_supplicant -Dwext -iath0 -c/etc/wpa_supplicant/wpa_supplicant.conf
-P/var/run/wpa_supplicant -B
root 12548 0.0 0.0 2236 332 ? Ss 23:09 0:00
/sbin/wpa_cli -B -P /var/run/wpa_action.ath0.pid -i ath0 -p
/var/run/wpa_supplicant -a /sbin/wpa_action
and an additional file /etc/wpa_supplicant/wpa_supplicant.conf has been created
automatically. Note that the command line for the wpa_supplicant shows the
conf-file to be at /etc/wpa_supplicant/wpa_supplicant.conf while
/etc/network/interfaces states /etc/wpa_supplicant.conf. Cleaning up:
r...@vulpecula:/etc# ifdown ath0
r...@vulpecula:/etc# killall wpa_supplicant
r...@vulpecula:/etc# rm -r /var/run/wpa*
No wpa_supplicant processes are running now, /var/run/ is clean. Starting
wpa_supplicant directly:
r...@vulpecula:/etc# wpa_supplicant -Dwext -iath0
-c/etc/wpa_supplicant.conf
ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/ath0' manually if it is not used anymore
Failed to initialize control interface 'DIR=/var/run/wpa_supplicant
GROUP=wlan'.
You may have another wpa_supplicant process already running or the file
was
left by an unclean termination of wpa_supplicant in which case you will
need
to manually remove this file before starting wpa_supplicant again.
after this, again the above two processes are running, and
/var/run/wpa_supplicant has been created. It turns out that this happens even
if ifconfig is used:
r...@vulpecula:/etc# ps aux | grep wpa
root 12690 0.0 0.1 4888 744 pts/1 S+ 23:25 0:00 grep
wpa
r...@vulpecula:/etc# ifconfig ath0 up
r...@vulpecula:/etc# ps aux | grep wpa
root 12694 0.0 0.1 4856 840 ? Ss 23:25 0:00
/sbin/wpa_supplicant -Dwext -iath0 -c/etc/wpa_supplicant/wpa_supplicant.conf
-P/var/run/wpa_supplicant -B
root 12702 0.0 0.1 4888 740 pts/1 S+ 23:25 0:00 grep
wpa
When opening a second terminal with top running while trying ifup ath0, the
following can be seen:
1. ifup starts wpa_supplicant
2. wpa_supplicant wants to activate the ath0 interface
3. this spawns a second wpa_supplicant, with different conf file (see
above)
4. wpa_supplicant (2) writes the control files into /var/run
5. after activating, wpa_supplicant (1) finds these control files, assumes
another instance is running and exits with error
6. ifup is cancelled due to error
After this it is possible to manually select a network using wpa_gui or
wpa_cli, but no automatic connection. The user is forced to put the conf-file
into /etc/wpa_supplicant/wpa_supplicant, since all other places are ignored.
Grepping for "/etc/wpa_supplicant/" in /etc gave no result. Neither hotplug nor
ifplugd are installed on the system, no udev rules regarding wpa exist, and
wpa_supplicant had been purged and re-installed cleanly.
Lots of regards, Jacob.
