[Simh] Unable to telnet to other hosts

Thu Nov 7 09:21:51 EST 2013

According to his first post he's already configured TCPIP, but it wouldn't
hurt to ask.

Priya, have you run "@SYS$MANAGER:TCPIP$CONFIG" to configure TCPIP?

I'm assuming also, that you already tried to input a host using the "SET
HOST" command and you entered "SHOW HOST" and got the error.  Try what
David suggested.
