Westine +Request for Comments: 847 D. Smallberg + J. Postel + February, 1983 + + + 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. + + TELNET + + RFC DATE ACCEPT TOTAL PERCENT + --- ---- ------ ----- ------- + 832 7 Dec 82 83 315 26 + 833 14 Dec 82 103 314 33 + 834 22 Dec 82 102 314 32 + 835 28 Dec 82 95 314 30 + 836 4 Jan 83 151 315 48 + 837 11 Jan 83 171 323 53 + 838 18 Jan 83 172 323 53 + 839 25 Jan 83 182 323 56 + 842 1 Feb 83 183 382 48 + 843 8 Feb 83 187 329 57 + 845 15 Feb 83 176 329 53 + 846 22 Feb 83 190 325 56 + + FTP + + RFC DATE ACCEPT TOTAL PERCENT + --- ---- ------ ----- ------- + 832 7 Dec 82 70 315 26 + 833 14 Dec 82 90 314 29 + 834 22 Dec 82 80 314 25 + 835 28 Dec 82 80 314 25 + 836 4 Jan 83 132 315 42 + 837 11 Jan 83 153 323 47 + 838 18 Jan 83 159 323 49 + 839 25 Jan 83 165 323 51 + 842 1 Feb 83 170 328 52 + 843 8 Feb 83 174 389 45 + 845 15 Feb 82 169 329 51 + 846 22 Feb 83 181 325 56 + + +Page 1 + + + SMTP + + RFC DATE ACCEPT TOTAL PERCENT + --- ---- ------ ----- ------- + 832 7 Dec 82 63 315 20 + 833 14 Dec 82 82 314 26 + 834 22 Dec 82 82 314 26 + 835 28 Dec 82 72 314 23 + 836 4 Jan 83 124 315 39 + 837 11 Jan 83 145 323 45 + 838 18 Jan 83 154 323 48 + 839 25 Jan 83 159 323 49 + 842 1 Feb 83 169 328 52 + 843 8 Feb 83 170 329 52 + 845 15 Feb 83 169 329 51 + 846 22 Feb 83 178 325 55 + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +Page 2 + -- cgit v1.2.3
