That’s great to hear, Mike! I think I might have been the author of some of that FTP code, while I was still an undergrad at RPI. It’d be fun to get that working again here at some point. I also did an rlogin implementation and an NFS implementation, though I’m not sure whether that code ever made it to other MTS sites.
I don't remember seeing rlogin or NFS code, but after nearly 25 years I can't be sure. The most likely place to find it would be on the redistribution tapes, but, unfortunately, they were all or mostly lost. [Redistribution tapes were a way for MTS sites to share stuff before the Internet. Everyone would send tapes of interesting stuff to Michigan and we would combine them all onto one tape and send a copy to everyone. There was no attempt to review or integrate anything.]
