Hmm, I have an additional port open:

tcp        0      0 192.168.0.1:139         0.0.0.0:*               LISTEN      2694/smbd           
tcp        0      0 127.0.0.1:139           0.0.0.0:*               LISTEN      2694/smbd           
tcp        0      0 192.168.0.1:445         0.0.0.0:*               LISTEN      2694/smbd           
tcp        0      0 127.0.0.1:445           0.0.0.0:*               LISTEN      2694/smbd   

But I don't know whether that's CIFS or something.  Are you able to
"telnet localhost 139"?  I suspect that doing that would also timeout,
whereas I can connect immediately.  If telnet also times out, it's
almost certainly a firewall issue.  Also check your "hosts allow" line
in smb.conf.

Cheers,
Adam.
