Topic: alternative sshd port

[P Kidd]

I added Port 23 to sshd_config, and a specific external IP address to hosts.allow (SSHD: externalip/32 : ALLOW) and changed /etc/services port 23 to ssh from telnet, restarted sshd and I can only connect through port 22 not port 23 from the specific external address (internally no problem either port) - does ipchains block the "telnet" port?

this entry is redundant

I guess so as when I inserted the following line port 23 external access works, but is this ipchains insertion OK?  Port 22 accepts any ip address, and if I just Append the following, external access is blocked so it seems OK to me

ipchains -I input -p tcp -s externalip/32 --dport 23 -i eth1 -j ACCEPT
