Who Talks TCP?
The list of hosts was taken from the NIC hostname table of 2-Dec-82.
The tests were run on 7-Dec-82 from ~12:01 am to ~2:15 am PST and from
~12:30 pm to ~7:00 pm PST.
Dead, refused, and unreachable hosts were retried 8-Dec-82 from ~3:15 pm
to ~4:30 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:
blank (not accepted)
refused
unreachable
dead
accepted
accepted+ (FTP allowed user anonymous, password guest)
