Static wired connection never succeeds

[jwoithe]

When configured to use DHCP, a connection to my wired network succeeds (assuming I have the DHCP server running elsewhere). However, if I configure the wired connection to use a static IP number instead, wicd never succeeds to make a connection. When "connect" is hit wicd goes off to do its thing. Using "ifconfig" in a terminal shows that it does in fact correctly set up the interface. However, after a few seconds this is undone and the GUI connection status reverts to "disconnected".

After turning on "debug" the following is written to the log file during a connection attempt as described above.

In other words, the daemon believes it has connected successfully and sends a message to this effect. However, the GUI doesn't seem to understand this, concludes that there was a problem and promptly shuts the connection down.

This is with wicd 1.7.0 running on Slackware 13.37, using the package provided in extra/ on the Slackware 13.37 distribution.

I have the same problem on Ubuntu 12.04 using wicd 1.7.2.3

I also have this problem on Gentoo (3.7.9-gentoo x86_64) and wicd-1.7.2.4-r2.

I think it is this command, that causes the disconnect:

/sbin/dhcpcd -k eth0

See man dhcpcd:

" -k, --release
             This causes an existing dhcpcd process running on the interface to release its
             lease, de-configure the interface and then exit. dhcpcd then waits until this
             process has exited."

It *de-configures the interface*.

I have to admit that my last post was not very useful as it described the symptom not the cause.

But maybe this is of interest:

<pre>
wicd -f
dhcpcd[24122]: sending commands to master dhcpcd process
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory
</pre>

This is the output whenever I try to connect using the GUI/curses/cli to any network (wired, wireless with or without static IP).

Wireless connections via GUI only work with static IP

However, it also connects using DHCP when I issue the wpa_supplicant command with the parameters taken from /var/log/wicd/wicd.log directly in the terminal:

<pre>
wpa_supplicant -B -i wlan0 -c /var/lib/wicd/configurations/7444018d97c6 -Dwext
</pre>

Wired connections (static as well as DHCP) do not work using the GUI
However, when the network cable is plugged in it reconnects silently without problem.

Btw, I removed my old /etc/wicd dir and reinstalled wicd before testing. Gentoo's net.* initscripts (except net.lo) are not running.

I would like to help tracking this down, so please tell me what information I could provide.

Sry - I had dhcpcd running in the background....
After stopping dhcpcd everything works except wired connections with static IP using the GUI.

The output of wicd -f now is:

<pre>
dhcpcd[13366]: dhcpcd not running
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory
</pre>

However, wired connection with static IP works using wicd-cli and wicd-curses.

Sorry for 3 posts with little new information.

I have same bug and report here
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711757

I guess it's because update state and call disconnect after connect successful
so i mark daemon.Disconnect() in monitor.py

This bug also affects us. Latest version (1.7.4+tb2-5~deb9u1) on Debian 9.

Connecting a profile with wired static IP address via wicd-cli always works, with wicd-gtk almost always fails.
Applying the "time.sleep(3)" patch in monitor.py (as mentioned in the Debian bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711757) solves the issue for wicd-gtk.

Please consider solving this issue permanently (preferably in a less hacky way :).
