Unless telnet has some weird shell escape command, this should be safe:
Make a user id called "telnet" or whatever, giving it the login shell of
"/usr/ucb/telnet". So, the user "loggs in" as telnet, and then gets a
telnet> prompt. (Or rather, a "-telnet" prompt, since login execs the shell
like that) He can do: "open woo at woonext.dsrd.ornl.gov", or any other
hostname to be connected to, and execute any other normal telnet command.
