Check, but I believe that your sshd (the daemon) is compiled against libwrap. What this means is that there should be a /etc/hosts.allow file that will let you only allow access to the daemon from specified ip's. It's not a total solution, but it will cut down the noise quite a bit. jim On Fri, 2004-09-24 at 14:57, Meatplow wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > > Hello. > > I'm running RH Enterprise edition. > > I'm relatively new to iptables.
