I've got a remote tunnel, via

ssh -L 8022:host1:22

and connect to host2 via winswitch and the localhost:8022 tunnel.

Now, if I stop that outer SSH session (eg. via the "\n\n~." escape sequence) winswitch sees that the connection is severed, and displays "reconnect" in the servers menu.

But this doesn't work; on the first "reconnect" winswitch says that it couldn't connect, and only on the second try it really reconnects.

So it seems like there's some old state that is not being updated when a connection breaks.

I just installed xpra 0.4.0, and, to get my session upgraded in-place, did a kill of the winswitch_daemon, and reconnected.

winswitch tried to restart xpra, I believe:

26717 ?        S     22:55 /usr/bin/python /usr/bin/xpra --xvfb=/usr/bin/
26718 ?        S      4:55  \_ /usr/bin/Xvfb-for-Xpra-:67 +extension Comp
26786 ?        S      0:00 python /usr/lib/winswitch/delayed_start /home/
26787 ?        S      0:00  \_ /bin/sh -c xchat
26788 ?        Sl    35:13      \_ xchat
13327 ?        S      0:00 /usr/bin/python /usr/bin/winswitch_server --da
13371 ?        D      0:00 /usr/bin/python /usr/bin/xpra --bind-tcp=0.0.0

But something went wrong, and the new session was killed - *including* Xvfb and my active xchat.

The logfile has these entries:

Perhaps there's a way to get the new xpra running on a different port, and only grab the Xvfb and kill the old xpra when everything else is ready?

On new winswitch.org page there are some broken links or URL-s.

Generally, it means that anywhere windowswitch.org is used, winswitch.org should be used (e.g. SVN URL, ​http://windowswitch.org/svn/shifter/trunk/ on ​http://winswitch.org/dev/).

It also touches instructions on how to install under Ubuntu/Debian, which seems very important for new users (I spent a few precious minutes to go through this).
