When I try to telnet into a Linux box I'm working on, I get the
message "telnetd: All network ports in use". Everything seems
to be working aside from that (ftp, finger, etc), except
rlogin gives me a "out of ptys" error.

I can help you sort of.  I had this problem when I managed a Linux box for a high school.  They had a lot of students trying to connect and would get similar errors.  The workaround I did was to create more ttys for them to log in on.  To do this, you need to run the /dev/MAKEDEV script.  I don't have access to this right now, so I can't give you the syntax, but if you make more ttys your problem should go away.

To get the syntax, look at te script and there may even be a man page.  I hope this helps enough!

Ihave plenty of pttys, and I am the only one telnetting to the
box--so it is not a matter of having some, but not enough.
