Default SSH can't connect

Wether I run NX (nomachine) or SSH I get the same error message, no
matter what host I try to connect to.

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@70.236.39.98
ErrorMessage: ssh: connect to host 70.236.39.98 port 22: Connection
timed out

sometimes you may have changed the default port for ssh service. Check
whether the port is 22.
Check /etc/ssh/ssh_config in servers

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.

What is the -n -n After eth0 mean ?

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

14:05:10.307914 ARP, Request who-has 69.243.174.143 tell 69.243.168.1,

And it keeps running.

Yep, this sounds like a firewall, I have FC13 and working with Putty from
Windows/7 locally and across the net.

Run
sudo iptables -L -n

and see if port 22 is open to accept connections
