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:

= 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)
