looking for source code to University of Illinois "Network Unix"

by Paul Ruizendaal

Hi, I'm looking for the source code to "Network Unix" as described here: https://tools.ietf.org/html/rfc681 and/or its later development described here: https://archive.org/details/networkunixsyste243kell Actually, I'd be happy with finding the source code to any version of this Network Unix. This version of Unix had fairly wide use in the Arpanet community and was in use at several universities and organizations (e.g.: Rand, BBN, etc.) Would anybody here know of a surviving copy? Many thanks in advance, Paul

Re: [TUHS] looking for 4.1a BSD full kernel source

by Paul Ruizendaal

Hi Diomidis, Thanks for that link. This is exactly what I'm trying to ascertain, and I'm finding conflicting evidence. - The socket API was in a state of flux between October '81 and March '82 (when 4.1a was supposedly cut). By March '82 it was mostly there, but not until later in the year did it fully stabilize. - The BBN stack did not use the sockets API as late as January '82 - What I currently fathom from the SCCS files is that the socket API implementation was hard coded to use the nascent Berkeley stack. - But the BBN code was likely in the 4.x BSD source tree, outside of SCCS (Berkeley started out with the BBN code, but it morphed quite quickly and drastically) - In 1985 the BBN code finally enters SCCS (marked 'deprecated'); this code was integrated with the sockets API, and much developed from its 1982 form Either the below link is correct (and I think I may have contributed to its view in a private mail to Kirk), or there were two different distributions (4.1a BSD with Berkeley network code and 4BSD with BBN network code). The two may have merged into one in peoples' memories: 35 years is a long time. Finding the actual kernel source for the 4.1a distribution could provide clarity on this point. Perhaps Bill Joy could shed some light on the issue, but I don't have contact details. Having actual source removes all doubt.

looking for 4.1a BSD full kernel source

by Paul Ruizendaal

Hi, I'm trying to find out exactly what was in the 4.1a BSD distribution, as far as the kernel is concerned. The image in the CSRG archive comes from a tape that had a hard read error and does not include any kernel sources. Some of the kernel files were already covered by SCCS around that time, but not everything. My main focus is to understand tcp/ip networking in 4.1a and whether the kernel could be built with either the Berkeley or the BBN network stack. Does anybody know where I could find a full set of kernel sources for the 4.1a BSD kernel? Many thanks in advance! Paul
