Cluster computing requires a cluster of computers. For the past several years, I have been attempting to get work down without having a home cluster. This is no longer tenable, and I need to build my own.
One of the requirements for a home cluster is a progammable network device. I’ve purchased a second hand Junper SRC22.
Juniper SRX 220
Here are my configuration notes.
Table of contents
To start, I needed a Get console cable. RJ456 on one end, serial port on the other…excpet I don’t have any more serial ports on my workstations, so an addtional USB to Serial port cable to connect to that.
Console Cables
Yeah, just get a USB to RJ45 Console cable. But don’t expect to be able to buy one at your local office supply store.

Thanks for the post, helped out a lot.
Do you have the same device?
