I do not recall having seen an equivalent file with UoI's NCP Unix in = any of the surviving docs or sources - but that does not exclude a = library having existed to do lookups in a local copy the SRI-NIC host = file. In fact there is some evidence for that in the 2.9 BSD source. The only surviving copy of the 4.1a (network) source code that I know is = in the back-port of this code to 2.8/2.9 BSD. This code includes = #ifdef=E2=80=99ed code for accessing the SRI-NIC online host table via = NCP: https://www.tuhs.org/cgi-bin/utree.pl?file=3D2.9BSD/usr/net/local This source also contains tools to convert the SRI-NIC data into - inter = alia - a hosts file: = https://www.tuhs.org/cgi-bin/utree.pl?file=3D2.9BSD/usr/net/man/man8/htabl= e.8 = https://www.tuhs.org/cgi-bin/utree.pl?file=3D2.9BSD/usr/net/man/man8/getta= ble.8c It would seem that the modern host.txt on Unix evolved late =E2=80=9981 = (BBN code) to early =E2=80=9982 (4.1a BSD). Possibly NCP Unix has prior = work. Paul
