Dear Debian team,
I am using ifupdown package on Debian 11.7 with one wifi
interface(if-sta0) in STA mode with sysvinit (no systemd). As a
result, of course, i am also using supplicant daemon supplied by
wpasupplicant Debian package.
In order to search complex issue when usging multiple AP targets, i
would to use debug feature as defined in wpasupplicant documentation.
~$ zgrep debug /usr/share/doc/wpasupplicant/README.modes.gz
In order to debug connection, association and authentication problems,
increase the verbosity level of wpa_supplicant to log debug output by
adding the wpa-debug-level option to /etc/network/interfaces like in
wpa-debug-level 3
My current configuration for this interface (if-sta0) (file
/etc/network/interfaces) is ...
.....
# interface 2.1/17 (if-sta0) (physical):02:00.0 Network controller:
Intel Corporation Wireless 7265 (rev 59), WLAN interface on motherboard
in STA mode
allow-auto if-sta0
iface if-sta0 inet dhcp
wpa-group CCMP TKIP
wpa-pairwise CCMP TKIP
wpa-proto WPA RSN
wpa-key-mgmt WPA-PSK
wpa-auth-alg OPEN
wpa-debug-level 3 # either 1,2 or 3
wpa-driver wext,nl80211
wpa-iface if-sta0
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-logfile /var/log/wpa_supplicant.log
wpa-psk "test-debian"
wpa-ssid "hn-tplink-re450-275-2.4Ghz"
wpa-ctrl_interface /var/run/wpa_supplicant
wpa-conf /etc/wpa_supplicant/wpa_supplicant.if-sta0.conf
.....
After following command ....
sudo ifdown if-sta0;sleep 1;sudo ifup -v if-sta0
The interface shut down, then wpasupplicant is correctly launched,
then association is done, and final dhcp is also done, so that no
error occurs, perfect (!)
Debian ifup/ifdown launch daemon with following parameters...
ansible@hn-asusgl752-400:~$ ps auxww |grep supplic
ansible 15775 0.0 0.0 5500 892 pts/1 S+ 14:25 0:00 tail -f
/var/log/wpa_supplicant.log
root 20123 0.1 0.0 11776 3524 ? Ss 22:23 0:00
/sbin/wpa_supplicant -B -P /run/wpa_supplicant.if-sta0.pid -i if-sta0 -D
wext,nl80211 -f /var/log/wpa_supplicant.log -c
/etc/wpa_supplicant/wpa_supplicant.if-sta0.conf
ansible 20326 0.0 0.0 6228 1048 pts/18 S+ 22:23 0:00 grep
supplic
As you can see, it seems that option "-ddd" is not computed by Debian
infrastructure when reading "wpa-debug-level 3" into
/etc/network/interfaces, it is therefore not possible to debug this
daemon.
Thanks to give me one method to force debug daemon mode.
Please give me a method to force debug daemon mode. Please note that I
tried the following line in the interface definition, but without any
hit ?
pre-up /usr/sbin/wpa_supplicant -B -D nl80211,wext -i if-sta0 -c
/etc/wpa_supplicant/wpa_supplicant.if-sta0.conf -f
/var/log/wpa_supplicant/wpa_supplicant.log -t -dd
Best regards
