Thanks. I tried it now the way you explained. Unfortunately, I still see the
problem. Just in a different way.
It seems to be the problem with the pre-disconnect script setting that wicd
provides. If I add a script there (~/bin/vpnc-disconnect.sh) and initiate a
connect, wcid triggers the disconnect script but never returns.
Now there could be many things there.
Suppose I am connected to my home network and then am initiating a connect,
while my vpn is not connected, a vpnc-disconnect is requested. This should
result in vpnc-disconnect exiting with an error code. But still, wicd should
not be bothered about that.
In this case, it looks like wicd executed the pre-disconnect script and then
went haywire.
Once the pre-disconnect script is removed, wicd works good. So, the problem
could be specifically with the pre-disconnect part given that post-connect
seems to be working properly.
And yes, all this information should be a good candidate for the README.Debian
file.

No. Couldn't reproduce it. Will see it later.

Yes, especially after the whole fiasco of network manager in trying to solve a
simple problem, "network management"
I still would request you to give it a personal consideration as a core
package especially given that it serves a "core service".

IMO yes. wicd is simple and small and that is its biggest strength. It doesn't
need a wicd-vpnc wicd-openvpn ..... to just do basic tasks.
The scripting mechanism is important because this gives users the great
flexibility to do additional network management. I think the upstream should
just spend a little more time on it and make it robust.

Hmmm!! The same ExecuteScript is called in both pre/post script execution.
I think you might want to look a little at the pre-disconnection part. I am
attaching the logs.
It could be that vpnc-disconnect.sh is executed while there is no vpn
connection, but still it should proceed with network connection, which is not
the case.

I think it is a real bug in there. Thank you for your work.
