                   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:

= tcp (no particular services mentioned)
= tcp/telnet
= tcp/ftp
= tcp/smtp

Results for each service:

lank (not accepted)
efused
nreachable
ead
ccepted
ccepted+ (FTP allowed user anonymous, password guest)
