These are the computers that operate my network infrastructure, as well as any Unix machines that aren't Sun. While my main focus is Sun machines (see my Sun page for more info), I do also focus on Unix as a whole as well.

My Mac Mini G4 used to have a place here, as it ran OpenBSD and was responsible for routing, DHCP, and DNS for my network. It was also what directs network boot clients to my IBM x3250. That server ran Solaris 10, and hosts files necessary for PXE boot, and Sun Jumpstart, as well as the boot files necessary for booting OpenFirmware Macs over the network from the OpenFirmware prompt. The Solaris installation did eventually break, so I ended up installing NetBSD on it and consolidating the functions of the Mac Mini and what the x3250 was already doing into one server, which also increased speeds on the network given the server itself has dual gigabit ethernet NICs.
The RS/6000 44P/170 is the first RS/6000 machine I have owned and has been quite a learning experience, given that IBM has a somewhat specific way of expecting machines to be configured on a network and within their ecosystem. I have run a Minecraft server on it as a test of its abilities, and I would like to benchmark it comparative to my 333MHz Sun Ultra 5 and my Power Mac G4, as a machine of a different architecture at the same clock speed and a machine of a similar architecture at just over 2x the clock speed.
