I only see output when I ssh from Dom0 -- nothing when trying fromputty client.
Do you have any firewall in place that might be dropping connections ?

No, the closest thing would be the standard iptables rules on Dom0 ...but it looks "okay" to me.


The same problems arise from other boxen on the same network too.

Target eth0 network is 192.168.1.0/24 with eth1 network being192.168.10.0/24

In the interest of solving this and not making any changes to the outputwhich _may_ cause confusion, I've included some extra info here.


If anyone needs any more information, please let me know what to provide.
