Re: Re: Re: how to access machine using telnet

In my case (some time ago) I was dealing with a headless server I was
set up on the other side of the world. (I live in Japan - server was
in Canada) I wanted telnetd to be running, but not used except as a
backup way to get in if sshd failed to work. (Which had happened once
after changing the config file.) The insecurity of telnet is that
everything is sent in the clear and passwords could be 'sniffed' on
the local network. As a backup service there would be nothing to sniff
unless I couldn't get in via ssh.

Or somebody tried running a password cracking program against your
telnet server. If you want a backup in case sshd goes mad, better get
access to the machine using an out-of-band mechanism, like a serial
line connected to a modem.
