Who Talks TCP?
The list of hosts was taken from the NIC hostname table of 2-Dec-82.
The tests were run on 14-Dec-82 from ~8:00 am to ~4:30 pm PST.
Dead, refused, and unreachable hosts were retried 14-Dec-82 from ~10:15 pm
to ~11:45 pm PST.
(Duplicately listed hosts were removed slightly differently from the way
they were in last week's report, so the row totals in the summary
tables below are slightly changed from last week.)
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:
blank (not accepted)
refused
unreachable
dead
accepted
accepted+ (FTP allowed user anonymous, password guest)
