Basically, I want *all* the machines on my local LAN to be able to telnet and ftp to each other. Between the older machines (Suse 5.2, Suse 7,2 and red Hat 9) there is no problem.
Why such old machines? Legacy software? For reference?
You will almost certainly find that the debian systems are /not/ running telnet and ftp daemons. This is known as a /jolly good thing/.
There's nothing badly wrong with FTP.
You do not have to have telnet running for remote logins. You could perhaps have some strange data transfer using the telnet protocol. Eg, maybe transferring weather data from a weather sensor to some other processing system. With no logins, the fact that you run telnet does not matter [in the oft-touted security sense].
Now, if you are using telnet to do remote logins, I'd strongly suggest you move away from telnet. This may or may not be easier said than done.
You will probably find that telnetd is run out of inetd.conf (or xinetd) whilst the ftp daemon may be running standalone on the old Suse machines and started by scripts in /etc/init.d or /etc/rc(n).d (I can't remember offhand).
Yes, check /etc/inetd.conf or xinetd.conf and make sure the telnet part of the configuration is either not commented out, or is inserted (if it was not present there to begin with).
The text file for RFC 854 contains exactly 854 lines. Do you think there is any cosmic significance in this?

Do we really care about the massive signature?
