This page is for the configuration of the blade servers.

Specifications

The server is a HP/Compaq blade chassis with 5 BL10e blades. Thanks to HP NewZealand for sponsoring this machine!

A second chassis and ten extra blades were later donated by The Total Team http://www.totalteam.co.nz/ via CraigFalconer.

Software

The blades all run Debian GNU/Linux 4.0 (Etch). Read about the set up at WlugAdmin. The server was configured and is maintained by the WlugSysadmins.

Where is it hosted

The blades

There are 5 blades:

  • hoiho.wlug.org.nz: Shell account for users
  • mail.wlug.org.nz: MailServer
  • www1.wlug.org.nz: Primary WebServer
  • www2.wlug.org.nz: Secondary WebServer. This is usually load balanced with www1 using a DNS RoundRobin, and used to store backups of the other blades. If any other blade fails, then this server can have the appropriate backup restored onto it, and removed from the DNS RoundRobin and become the missing blade.
  • db.wlug.org.nz: This is the "services" blade, running the DataBase(s), LDAP, DNS etc.

The blades have 2 interfaces, eth0 will have their realworld IP and network, eth1 will have a private network between all the blades using 10.100.100.0/24.

Orcon have allocated 60.234.66.112/28 for WLUG's use, .113 is the gateway

Things to check on each blade:
