Wether I run NX (nomachine) or SSH I get the same error message, no

And on the host servers SSHd is running.
And so is the Client box.

Running NX
Error message: ssh: connect to host 70.236.39.98 port 22: Connection
timed out

Running $ ssh jim@xxxxxxxxxxxx
ErrorMessage: ssh: connect to host 70.236.39.98 port 22: Connection
timed out

I forgot to add;

These are all FC13 boxes, clients and hosts and the Firewall in each box
has SSH check as Trusted Service.
Try keeping a running
tcpdump -i eth0 -n -n
in a different terminal before invoking ssh.

You should be able to see if packets are exchanged between the machines.
If you see your packets but no packet from the other machine, one of the
firewalls is interfering. You can sniff on the other side too for more
information.

Running your command I get a steady output of IP's I have never seen,
example below

Quite strange output: ARP requests for 69.*, 71.* and 73.* networks
and nothing else. You only pasted 0.3 seconds of activity. Was there
something for 70.236.39.98 when you tried to ssh?
What kind of network connections do you have?
Is the 70.236.39.98 machine supposed to be contacted on eth0?

Would you give us some info about your network connection?
ifconfig -a
route -n

Thanks.
