Who uses it? What can it do? What good is it? It's for authenticating people. The way it works is a remote machine sends some information along with the telnet port that the local machine is connected from and the remote machine returns some information some of which contains the e-mail address of the person from the local machine that is accessing the remote machine. (look at RFC 931 for an in depth description). > and if a DOS-based telnet client doesn't recognise this auth thing, why > does it take 10 seconds before the login: prompt appears? You've got a slow name server maybe?..and the dos clients name is being resolved during that time?
