Minicom to a Juniper SRX-220

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.

Here are my configuration notes.

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.
