    Spam load again got to be too much for the computer I had dedicated to the task. Decided I really needed to give the clustering thing another try. I decided the easiest thing to do would be to build yet another dedicated computer to handle just the spam filtering. Since I would be starting from scratch on an install, I had the ClusterKnoppix CD install itself to the HD. I then burned another CD and setup 2 more computers on my cart and booted them from the CD. All 3 computers joined together...

    In attempt to get a long range signal temporarily, I rigged up a DirecTV dish with a small directional antenna I had. Being just a hack I first used tape to tape the antenna to the LNB. Hoping to improve the signal I removed the LNB and clamped the antenna in approximately the same place as where the LNB was. Moving the antenna didn't really seem to help much. I could only get a signal of about 1-3 on average. Fortunately the Netgear card I'm using will actually move data with such a...

    Found a copy of ClusterKnoppix that appeared to have the same kernel version of the copy of CHAOS I have. Fired it up and was able to get the CHAOS computers to join by giving them the j2 option. Also got that one with the dead PS repaired and so now I have 4 computers in my cluster. Figured a good test would be a linux compile so I started one up. One by one as the load went out to the other computers, they kernel dumped! Woo! Wait, that's not a good thing. I think I can get one of them to...

    I went around and counted up all the PCs I had sitting around that are complete but aren't powered on. There's no less than 14 of them. I also have a couple of motherboards and cases and could probably build 2 more Pentium class, and maybe even a couple of 486s. Cleared my entire table off and gathered up 5 computers and downloaded CHAOS and BCCD isos and burned them. CHAOS wouldn't boot on 2. BCCD wouldn't let me "runinram" and I didn't want to burn a second...

    For the last few weeks the spam load on one of my servers has gotten way way out of hand. The computer is averaging a load of 4-7 constantly. The number of sendmail processes that are running just drag the machine to a crawl. Over a year ago or more I changed sendmail around so that it has 4 queues and installed re-mqueue from Paul Pomes. This helped dramatically . Stuff that was sticking in the queue and dragging everything else down now gets automatically moved to queues that run far less...
