Spent most of tonight re-wiring connections from 10-base-T to 100-base-T. At this point all of the servers tht move any significant amount of traffic are connected 100-base-T on an N-way switch. This should eliminate the one remaining point of occasional data congestion here; particularly Ultra1 which on which the 10-base-T connection was saturating pretty badly (I saw local ping times exceeding 200ms on occasion to that box). I hadn't anticipated some of the interuptions that resulted tonight, particularly with the Ultra1, when I first put the cable together for it, one end had a flakey connection and so I thought everything was working, walked away and it stopped, and at this point I had pulled the 10-base-T wiring out so it was isolated for the amount of time it took me to get a new RJ-45 plug on the end. But all the heavy stuff that is service impacting is now done and out of the way. The shell server, the web/ftp/file server, irc, the client mail server, the connection to the router, all 100-base-T now. The servers that remain 10-base-T at this time, mx1/mx2 which receive mail from the net and do list expansion (these rarely saturate a 10-base-T connection), chat (the bot machine), commerce (the SSL web server), Eskinews (news), and our workstations, and all of these are going to be replaced and the connections will be upgraded as that is done.
