Well I guess it has been, at your expense, a lesson for your 15 colleagues and a LUG.

I've taken measures, including shortening all flyleads to 1/2 metre and using four different coloured ones instead of beige. -----Original Message----- From: Fisher, Robert (FXNZ CHC) [mailto:[EMAIL PROTECTED] Sent: Thursday, 11 November 2004 9:16 a.m. To: '[EMAIL PROTECTED]' Subject: RE: On Topic - Ethernet problems (answer) My question is....

From 09:00 to about 11:40 My only excuse is that there was absolutely no indication of the site or nature of the problem. The little clue we needed was that The print servers were all disabled AND tcpdump was running and showed a quantity of packets (couple hundred in a few seconds) going to a printer's IP on port 9100 (the jetdirect port) >From that we deduced what could have happened... Then it was a matter of checking 700 outlets in hundreds of rooms for the possible cause. The good thing was I fluked and guessed which room it was in. Fortunate.
