Who Talks TCP? -- Survey of 15 February 1983
The list of hosts was taken from the NIC hostname table of 3-Feb-83.
The tests were run on 15-Feb-83 from 8 am to ~12:30 pm PST, and on
16-Feb-83 from 10 am to ~11:10 am PST from ISI-VAXA.ARPA
Dead, refused, and unreachable hosts were retried from 10 pm 16-Feb-83
to ~6:40 am 17-Feb-83.
Claims are taken from the NIC host table:
T = tcp (no particular services mentioned)
t = tcp/telnet
f = tcp/ftp
s = tcp/smtp
Results for each service:
