Re: [CentOS] Understanding iptables

P.S.: Once again: although it's great that you are digging into the problem, using iptables, and learning a lot on the process, you should *REALLY* consider ditching rsh/rlogin and sticking to SSH. I would consider using rsh/rlogin instead of SSH today about the same as using gopher instead of the WWW these days (for those of you who still remember it).

In an isolated subnet (where the only users are root anyway on all machines - think research lab), it might have its uses (e.g. when ssh via key-authentication is too slow for whatever is needed).

So, I wouldn't ditch it completely. But on a normal LAN, it's not a good idea.
