Did yo have fun playing with the overlays? :-)

Probably easier to turn them on on Ultrix-11. Just modify inetd.conf.
Actually, I just looked and ftp is on by default. Telnet is not.

I suspect you will be somewhat disappointed with networking in
Ultrix-11. Not that there is something wrong with it, just that
the hardware is nothing like you are used to. In the early days
of networking it was not unusual for systems like the PDP-11 to
crash just because of the traffic passing by on their network
connection. The advent of switches helped alleviate that but it
is still common to crash a system by pushing data at it from a
modern ftp. I expect FileZila will do it. To be honest, I always
preferred Kermit for moving files. It is possible to keep packet
sizes down and even slow down the transfer rate to give the PDP
time to handle it.
