Hi Waldirio: I tried telnet earlier from one DomU to another [root@localhost ~]# telnet 192.168.17.201 22 Trying 192.168.17.201... Connected to 192.168.17.201 (192.168.17.201). Escape character is '^]'. and then it just hangs... So it looks like I can connect to the port from DomU to DomU. But from Dom0 to a DomU [root@gxn-wn2 ~]# telnet 192.168.17.201 22 Trying 192.168.17.201... Connected to 192.168.17.201 (192.168.17.201). Escape character is '^]'. SSH-1.99-OpenSSH_3.9p1 Connection closed by foreign host. I am scratching my head... David > Hello David > > Let's try fix this problem.
