something of interest to gated users
by Paul A Vixie 23 Oct '97

23 Oct '97

i know that programming is passe, and i apologize for not being able to think of any good political statements to make here, but if you're running bgp via gated and you'd like to know which of your peers are misconfigured, the following perl script may be of help. change $us as appropriate. note that you need "traceoptions state detail send open recv open" in your bgp declaration, and the script below wants your gated.log file as input. #!/usr/bin/perl $us = "204.152.184.134"; while (<>) { chop; next unless /^\w\w\w \d\d (\d\d\:\d\d\:\d\d)\s+/o; ($ts, $_) = ($1, $'); if (/^BGP RECV /o) { $_ = $'; if (/^((\d+\.){3}\d+)\+\d+ \-\> ((\d+\.){3}\d+)\+\d+$/) { ($outer_ts, $their_ip, $our_ip) = ($ts, $1, $3); }elsif (/^version 4 as (\d+) holdtime \d+ id ((\d+\.){3}\d+)/){ if ($ts eq $outer_ts) { ($as, $id) = ($1, $2); } } } elsif (/bgp_pp_recv\: no group for ((\d+\.){3}\d+)\+\d+/) { if ($ts eq $outer_ts && $our_ip eq $us) { $_ = sprintf("as %5d ip %15s id %15s", $as, $their_ip, $id); $result{$_} = $ts; } } } while (($key,$val) = each %result) { print "$val: $key\n"; } exit 0;

Hi - We are looking for a host for the next meeting (NANOG 12) to be held in the February '98 timeframe. We have a "Tips for hosting a NANOG" writeup on the web page: http://www.nanog.org/tips.html in which we describe what is involved and what has worked well at past NANOGs. If you think you might be interested, please speak with me at NANOG 11 in Phoenix, send me e-mail (wbn(a)merit.edu) or call me at (313) 764-9430. Thanks, Bill -------------------------------------------------------------- William B. Norton <wbn(a)merit.edu> (313) 764-9430

Gigaswitch is a crossbar-based _packet_ switch. I recall reading fairly comprehensive article on its internals. Most likely it is still available from somewhere on Internet. If i understand correctly, its ATM interfaces do packet shredding/reassembly. --vadim

Sprint NAP
by jvanick＠megsinet.net 22 Oct '97

22 Oct '97

Hi There, I know that this is a little off-topic, but I was wondering if anybody could give me any pointers on who to contact to get into the sprint nap... we're bringing up OC3c to Ameritech NAp and a concentrated-FDDI connection into MAE-East, and while we're running through the east coast area we though we'd get into the sprintnap as well... Any info would be appreciated. Thanks! -- Jason Jason Vanick ------------------------------------------ jvanick(a)megsinet.net Network Operations Manager V: 312-245-9015 MegsInet, Inc. 225 West Ohio St. Suite #400 Chicago, Il 60610

Exchange point stats info
by Jeremy Porter 22 Oct '97

22 Oct '97

I was wondering if someone who knew something about the current status of the group(s) that were working on a standard data collection format for exchange point statistics, could speak up. It seems to me that operators could still get valuable trend information out of published data from exchange points. However this data would be more useful if compared accross multiple exchange point, as there are at least 40 in north america alone. (Although most of those are smaller exchange points.) (Then if we could just get providers to publish info on private exchange points...) --- Jeremy Porter, Freeside Communications, Inc. jerry(a)fc.net PO BOX 80315 Austin, Tx 78708 | 1-800-968-8750 | 512-458-9810 http://www.fc.net

If the exchange_points becomes "WEB-farms" I'm not so sure they will survive, as there is no_one responsible for the service, as all lives in the "DMZ-zone". -Peter
