Remember boys and girls, "getpeername()" only works on sockets.
I guess I was not clear - the program does not open a socket -
it inherits some filedescriptors (0 1 and 2).

Sombody already suggested that I place a program between inetd
and telnetd, but I was hoping to not have to resort to such
yuck - I would rather not modify the system.
