Although I thought the default in the 5 series of redhat/centos was to leave port 22 open. it could also be that you don't have the ssh daemon turned on/possibly even installed (?) I'd make sure you have ssh turned on (from the linux machine, ssh to localhost, telnet localhost 22, ps -ef | grep sshd, service sshd status, chkconfig --list | grep ssh ) if all that works and looks OK, then try turning off firewall (service iptables stop) then try to ssh in from your other machines if that's ok, then back to the linux machine's console and do service iptables start iptables -I INPUT -s ${cdir of your lan[1]} -p tcp --dport 22 -j ACCEPT service iptables save and I'd think you should be set. [1] if your LAN is 192.168.0.0 with a netmask of 255.255.255.0 the CDIR would be 192.168.0.0/24, not sure how much you've dealt with that. googl will be your friend if you have an odd netmask. some of these options may be off, I don't use centos 5 much these days and all I'm putting in here is from memory, so I might be missing some stuff, but I think it's reasonably close. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
