Or you could buy an Excelan unibus ethernet card and their Exos front-end TCP/IP implementation. It adds about 8K to your kernel and has the 4.1c network system call semantics, but it offers the standard suite of network utilities (rcp, rsh, telnet, etc). I have done that here on some PDP11/45's (not enough core to handle 2.9's network code) and it works fine. Good throughput too (~60Kby/sec). It takes about a man-week to make the mods necessary to get the drivers to work on 2.8bsd. I have the 2.9 stuff if you're interested. -tcs Terry Slattery U.S. Naval Academy 301-267-4413 ARPA: tcs@brl-tgr.arpa UUCP: decvax!brl-bmd!usna!tcs
