Last time I've tried to clear up a problem, I was asked: why I am using non-standard software :) Basically, it does look like some firewall does not allow connection to X-server, it takes about a minute before the error is reported. If the listener was not there, then the error would be immediately clear. In this case the SYN is sent, dropped by firewall and the client waits for answer and tries again. Now, is it possible to tell X-server to use some port on localhost only? Hopefully firewall does not care about connections to localhost, and if it does, then I can bug admins about useless restrictions that prevent important communication on my host. Best regards Andrey
