I have dude 4.0beta2 setup under wine. Everything is working fine apart from the web access. this is the netstat results:
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 *:2210 *:* LISTEN
tcp 0 0 *:2211 *:* LISTEN
tcp6 0 0 [::]:ssh [::]:* LISTEN
as you can see no web access running on port 80. it is activated in the dude server configuration.
