Adam Young: Minicom to a Juniper SRX-220

News - NETCreator - 2018-05-14 23:45:56

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.

[TOC]

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.
