Three weeks ago I powered down my oldest Linux server.
It started is useful life as a NFS server for mail.pt site, moved to MySQL server of EVOLUI.com, and now is going to rest a bit.
It went online March 1999. I pulled the plug in 27th, January 2008.
It still has the original CPUs (dual PIII, 450Mhz), the original memory (although half of it is from an upgraded after I moved it to MySQL server, for a total of 1Gb), and this is the real kicker, the same 4 data SCSI disks, connected to a DAC9660 RAID SCSI controller.
I don't remember the original Linux distro, but given that the servers where assembled by me and Celso, I guess he suckered me into installing Debian on the box. Lately it was running RedHat 7.2 (Enigma), with a 2.4.18-17 kernel.
They don't make them as they used to.
