No, it doesnt seem to be so simple as a bad cable. Wish it was. I'm
suspecting maybe iptables is doing something? Anyway, more info:

1) I have 4 Linux machines here at home. Two are Gentoo, two are FC2:

Shadow - Gentoo - 192.168.10.26
Flash - Gentoo - 192.168.10.29
Godzilla - FC2 - 192.168.10.101
Wizard - FC2 - 192.168.10.5

All 4 machines have access to the Internet. (No bad cables, and in
fact I'm sending this email from Godzilla.) Both Gentoo machines are
accepting ssh connections from all other machines. (Gentoo or FC2) 
Neither FC2 machine is accepting ssh connections from any other
machine.

Here on Godzilla netstat -rn looks like:

[root at Godzilla root]# netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.10.0    0.0.0.0         255.255.255.0   U         0 0          0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0
0.0.0.0         192.168.10.3    0.0.0.0         UG        0 0          0 eth0
[root at Godzilla root]#

The second entry seems a bit bogus. What's going on there?

I can ssh to flash (gentoo) from Godzilla (FC2) and get netstat info.
It looks better:

flash root # netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.10.0    0.0.0.0         255.255.255.0   U         0 0          0 eth0
127.0.0.0       127.0.0.1       255.0.0.0       UG        0 0          0 lo
0.0.0.0         192.168.10.3    0.0.0.0         UG        0 0          0 eth0
flash root #

However, I cannot ssh from flash to Godzilla. On flash I have sshd running:
flash root # ps aux | grep ssh
root      7643  0.0  0.2  3168 1424 ?        Ss   09:43   0:00 /usr/sbin/sshd
root      8473  0.0  0.3  6000 1920 ?        Ss   14:23   0:00 sshd: root at pts/1
root      8489  0.0  0.0  1388  488 pts/1    S+   14:25   0:00 grep ssh
flash root #

Here on Godzilla I have sshd running also:

[root at Godzilla root]# ps aux | grep ssh
mark      2748  0.0  0.0  3308  712 ?        S    10:54   0:00
/usr/bin/ssh-agent /etc/X11/xinit/Xclients
root      3170  0.0  0.1  3664 1492 ?        S    11:07   0:00 /usr/sbin/sshd
root     22818  0.0  0.0  3584  596 pts/1    S    14:26   0:00 grep ssh
[root at Godzilla root]#


What am I missing???

Thanks,
