Hardware ======== This server is an AMD Athlon II X2 250 Regor dual-core 3.0-GHz CPU sitting next to one 2-GiB DDR3 SDRAM module, all on an Asus Micro-ATX motherboard and sitting inside a very old and bare Gateway chassis. Connected to the board is a 500-GB 7200-RPM hard disk drive. Powering the whole machine is a 400-W ATX power supply. One front-mounted 80-mm fan keeps the case and components cool. Software ======== This server runs Debian GNU/Linux. There is no non-free software (not even firmware) installed on this system. I even have plans to someday port coreboot (freely-licensed and high-quality boot firmware) to my server's motherboard (and I purchased a board for which a port should be easy). With the help of apticron, I keep the system up-to-date with proposed updates and security fixes. These documents are served by the Apache Web server with `mod_include` for SSI parsing. My mail server of choice is Exim 4, however port 25 is currently firewalled. I manage virtual hosts in Apache httpd and Exim using [VHC](projects/vhc/).
