I had root aliased to myself at my workstation. But on the external interface, port 25 is not open. The iptables rules accept connections from a relaying mail server on port 2525 on the external interface, and forward them to my mail server using the NAT tables.
I figure if no one can hit from the outside world, it would be secure enough to run. Just to be paranoid, I figure I'll reinstall it, with Debian, and turn off both sendmail and sshd. I have it connected to my workstation via serial console, so I don't need sshd anymore. Then there should be no network stuff other than the dhcp client, which I need for access to roadrunner. > > -- > ,-----------------------------------------------------------------------------. > > Adam Keys | > > < > > [EMAIL PROTECTED] | Adam Keys Development < > > ICQ# 11772935 | Ubercoder > > < > > http://mk.hotweird.com/~adam | > > < > ,-----------------------------------------------------------------------------. > I wonder if I'm insecure, secure, secure about my insecurity, or secure about > covering up my insecurity. > `-----------------------------------------------------------------------------' > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".
