oh, i've got it alright, but don't understand how to use it yet.
i've generated keys here and there, plopped this in and that
out, but still haven't been able to connect.
but i'm only using telnet on my internal 192.168.*.* intranet;
i know it's a security disaster waiting to happen, but until
i have time to grok ssh, it's all i've got.
and i don't got ^Z.
and i doubt that ssh will solve the particular problem anyhow.
