Each node consists of 2 32bit Intel Xeon processor.
The cluster also includes an 8 port KVM switch, which is accessible from the terminals in the lab.
s1, s2, s4, s7, and s8 are running Ubuntu Server 7. s6 and s9 are running Ubuntu Linux 2.6.
Edgar Leon is using this cluster for his cache injection work with Mambo and K42.
s6 serves as the network router for mambo simulation nodes. s9 serves as a DHCP server and also as a K42 victim.
Note: Each Spider node has a 100Mbps and 1000Mbps card on them, all switched at 1Gbps. Be careful as to what speed you're connected when doing network timing experiments.
(Anyone who knows why a 10-node cluster is called spider please add the explanation to this page.)
Spiders have eight legs and generally two chelicerae on the tips of which you will find the fangs.
