False telnet server

[Spammy]

Has anyone ever heard of a false telent server that you can run in the place of the telnetd? I was thinking of one that would give you a login prompt, type a login id and password, then say the password was incorrect and take you back to the login prompt. I need to discourage someone from trying to find the telnet server and loging in, and was going to move the telnet server to a higher port and just tell the people that need to know, but this would help with discouragement.<br>

Why do you want to let a user type a username/password? Why not just serve a banner that tells the hopeful that telnet is not available?<br>

If you really want to go to the effort of writing a bogus telnet server then you could do it easily in perl or even tcl. From memory, the Programming Perl book has a server daemon script. IMHO tcl sockets tend to quicker and dirtier.<br>
<br>
Or... you could use the PAM library tools that usually come with Linux to make the logins secure (probably better).<br>
<br>
Even if you do change the port, a cracker could just run a port scanner on your box and find it anyway <br>
