There have been a few times I’ve thought it would be nice to have a small, “low end box” somewhere for various tasks and viewpoints to the world. They list some pretty good prices here, down to about a dollar a month for some of the very lightweight solutions.

Useful. I’m always forgetting how to do shell math.

I’ve used tc in the past, and it’s loosely related to something else I’m currently reviewing, but not tied directly enough that it’s something I want to delve deeply into at the moment. The quick takeaway is, if you are trying to emulate the characteristics of a network connection within a lab, this (probably) is the tool you’re looking for.

I think I’ve run across this before, but never really had time to play with it. There are a few uses that come to mind, some of them cited and others not. I like awk, and I use it with a fair degree of regularity.

Great article on configuring Cisco routers to do WCCP with a Squid server.
Handy reference covering some of the commands for configuring Microcore, and practical examples of how to make the configuration changes persistent across reboots. Used as a reference (one of many) in configuring an OpenSSL CA and FreeRADIUS server for an EAP-TLS wireless test environment

I’ve had this open in my browser for a long time now. I think it’s one of those tabs that was well aligned with something I was doing at one time, but I have moved on and forgotten what it was that I was working on at that time. Still, good content. I often write shell scripts for some quick, one-off deal and never come back to them, but I always try to write them so they fail gracefully and safely if possible. It doesn’t always work that way with time constraints, but it’s a good goal at least.
Didn’t really need the tab anymore at the moment, just wanted to record it as one of those things to come back to down the road if needed.
