cannot reach F16 box via ssh

[M. Fioretti]

Greetings,

I have just installed F16 on a friend's box. Now I want to enable sshd in
order to log in from home and do system administration, updates, etc...
for him.

Before F16, the same box was running Ubuntu and I could log in via ssh
without problems. Now every attempt from my home times out.

I have already enabled sshd, iptables (see below), and used the firewall
config tool to enable allow ssh incoming connections, but every attempt
times out.

Surely I'm missing something obvious, but what? Thanks in advance for any
pointer,
Marco
