Who Talks TCP? - Survey of 1 February 83
The list of hosts was taken from the NIC hostname table of 28-Jan-83.
The tests were run on 1-Feb-83 from 10 am to ~1:00 pm PST, and on
2-Feb-83 from 8 am to ~11:15 am PST from ISI-VAXA.ARPA
Dead, refused, and unreachable hosts were retried 3-Feb-83 from ~8 am
to ~1:20 pm PST.
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:
