I believe that TCP wrappers can do it provided the sessions are not using
encryption.
If I remember correctly the syntax is user@IPaddress or user@reverseDNS
popper: [EMAIL PROTECTED]
Personally, I prefer to use SSH based on DSA keys then use port
forwarding. I put the users in a menu where the only option is quit. I
allow popper from 127.0.0.1 only. Openssh has a free sshd. Teraterm has
a free ssh client, but it only suppports version 1.
