Cannot use Dude in Wine

Hi to everyone,

I’m trying Dude with Wine in my Slackware 12. Installation works absolutely fine, but I can’t connect to my remote server.
I’ve tried also with Debian, same result. No firewall between my linux box and remote server (telnet to remote server to port 2210 is ok).
I’ve tried also with root account.

There is some workaround about this?
Very thanks!

Francesco
