Silly is not the word. "Stupid" and "idiots" are the words that come to
mind. I have asked the it dept. several times to make it possible. If I
explain TOO MUCH about how insecure telnet/ftp is, they would take it
all away.
Thanks for your explanation on how to do it. I wasn't sure if the port
numbers had to be the same on both the local and remote systems. I had
tried the L switch for ssh but that does not appear to be correct. I
will also have to open a whole in the router's firewall for port 21.
