Abstract

One would not expect the percentage to reach 100, since some hosts will be down when the surveys are run, but many hosts are for special purposes and don't offer these services. We estimate that 37 hosts or 11 percent are in this catagory and the highest percentage one could reasonably expect is 89. TELNET

SUMMARY OF SMALLBERG SURVEYS

This is a summary of the surveys of Telnet, FTP and Mail (SMTP)

servers conducted by David Smallberg in December 1982 and January

and February 1983 as reported in RFC 832-843, 845-846. This memo

extracts the number of hosts that accepted the connection to

their server for each of Telnet, FTP, and SMTP, and compares it

to the total host in the Internet (not counting TACs or ECHOS).

One would not expect the percentage to reach 100, since some

hosts will be down when the surveys are run, but many hosts are

for special purposes and don't offer these services. We estimate

that 37 hosts or 11 percent are in this catagory and the highest

percentage one could reasonably expect is 89.
