We've run our LISTSERV service on a Linux machine for nearly a year. We have about two hundred lists, some essentially inactive, about 90,000 subscribers across the lists with a few lists of 2000 or more subscribers, 250 postings per day, and over 400,000 delivery attempts per day. We're not in the category of C-NET, but we have fairly significant load. The hardware is a Dell PowerEdge 2300 (dual P-II/450) with 512 MB RAM, and as much of the I/O as possible on a three-disk striping arrangement. We run qmail to keep up with the volume. We use the Debian distribution of Linux, installed through the network. This is not necessarily the easiest one to install. Maintenance is striaghtforward, though, and should be pretty obvious if you have unix background. Upgrades are trivially easy. The Debian team is good about getting security fixes up quickly. LISTSERV on Linux has been very stable for us. L-Soft used to recommend platforms with journalling file systems (specifically AIX) to help avoid problems with damaged files in system crashes and flaky customer backups. Since LISTSERV tends to have lots of files open, and since it caches files in RAM, it's fairly easy to understand how problems could occur in crashes. We migrated to Linux from AIX, which has JFS. Linux did not until recently, and I believe all of the options are still alpha or early beta. We're not using them yet. Ask L-Soft about the fee for converting your license. I was a little surprised at the price we were charged. I don't know what determines this. If you have unix background, carefully choose mainstream, quality hardware, and keep your software straightforward, you should find a Linux platform to be very stable and reliable. Converting a production service to an unfamiliar platform, though, is something you should think through very carefully. Dennis Boone H-Net
