Measuring and Controlling Power to Sun Blade 6000 Servers

Controlling and managing power to remote devices such as the Sun Blade 6000 used to be a major headache for System Administrators everywhere.
Once upon a time, administrators who needed to reboot or power down a remote network device often had no choice but to travel to a far-away installation site and manually flip a switch;  [...]

I saw this on the workbench in the office next door and I thought it looked pretty cool. It is really four MPC units tied together and talking to each other for easier administrator. They are connected via a high [...]

We leave the protocols that should REALLY be closed when running in a real world environment open (i.e. Telnet, web, SNMPV1/V2) to see what kind of attacks that we can [...]
