- Nope. You have to hack telnetd. The best way to do this would be to hack
- it to take arguments of what to run, and a flag to determine if you need to
- run code that you will steal from rlogind as well (ie: the device setup
- normally done by login). This will let you run bbs software or any other
- software you want to by specifying a line in /etc/inetd.conf with your
- new telnetd with it's arguments. For backward compatability, the lack
- of arguments should cause it to run as it currently does.
-
- An alternative might be to get the "socket" code ("socket" is a program to
- allow shell-level manipulation of sockets) and put it on the port you will
- telnet to for this service. This assumes that you aren't running the old
- telnet code on the originator or the old telnetd code on the target, and
- that the target is always a telnetd. If this is the case, then options
- negotiations can ake place normally; otherwise they will fail.
