Nope, not IP over Datakit, as I recall. It was quite interesting to work at a site (Bell Labs) where there were two distinct network technologies. [--snip--] This library was socks about seven years before socks, originally written by Presotto and Howard Trickey. The relay program was originally called “gated”, but that wouldn’t do after a while. I renamed it “proxyd”, and that is the first use of “proxy" in this context that I am aware of. If you were on AT&T’s intranet and wanted to connect externally, you ripped out the entire socket dance and replaced it with an ipcopen call. I also distributed common modified clients, like ptelnet, pftp, pfinger, etc. I still have all this code, and I suppose it ought to go in an archival repository. I can’t imagine that AT&T/Lucent/Alcatel/Nokia would care at this point. Anyone want it?
