Sean,
Do you have sshd listening on the I.P. addresse(s) of those interfaces
as defined in your /etc/ssh/sshd_config?
This would listen on all interfaces on all I.P. addresses:
ListenAddress 0.0.0.0
You can also find out what I.P. addresses sshd is listening on to
investigate more:
netstat -an | grep :22
tcp 0 0 :::22 :::* LISTEN

Using Fedora 9, openssh-5.1p1-3.fc9.i386.--
I have a multihomed machine with 2 external interfaces - eth0 and
eth3. I can ssh into eth0, but not eth3. Using logging with iptables,
I see the ssh packets coming in to eth3. But I see nothing in
/var/log/secure showing even an attempted login.
My iptables ACCEPT should work for any interface:
$IPT -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT #ssh
Any clue what I should look for now? I've tried ssh to eth3 from the
same machine that works to eth0. No luck.
FWIW, I can also ssh into the internal interface.
