TW My sysadmin toolbox

Filed under

I started experimenting with Linux for fun, first with Slackware, but in the last few years more with Debian and its derivative distributions. Lately I've been using Linux increasingly in my job. As I've gotten more experienced with Linux, I've started teaching Linux courses to colleagues. Connectivity and fast package and file management are important components in my administration toolbox.


OpenSSH is my all-time favorite set of tools. I often use it for port forwarding to networks I don't otherwise have direct access to. You can also use SSH as a SOCKS proxy using dynamic port forwarding, like this:
ssh -D 8080 remotehost
I can then set a SOCKS proxy in my browser to localhost, port 8080, and voilà -- my browser can access everything that remotehost can.


Socat has been described as "netcat on steroids." It can read from and write to files, pipes, and all kinds of sockets. I use it mostly for port forwarding (TCP relay). For example, to forward all incoming connections on port 1234 of my host to port 1234 of, I run:

LXQt Spin Proposed For Fedora 26

A new spin/flavor has been proposed for Fedora 26, one integrating the LXQt desktop environment. For those late to the party, LXQt is the formation of the LXDE and Razor-qt projects and built around the Qt5 tool-kit. Fedora currently has an LXDE spin while this proposed Fedora LXQt would continue to co-exist alongside the existing LXDE version. Christian Dersch who proposed the LXQt spin explained, "LXDE spin will exist until its maintainer will stop it, LXQt is independent from LXDE spin. So nobody is forced to change ;) Also both projects are maintained upstream so there is no reason to drop anything here." Read more Also: F26 Self Contained Change: LXQt Spin

Raspberry Pi 1 and Zero: Hands on with Manjaro ARM and PiCore Linux

In the previous two posts I wrote about SUSE Linux and Fedora/Manjaro ARM/Ubuntu MATE for the Raspberry Pi 2 and 3. The results were mixed, at best. This time I'm taking on even more of a challenge because I'm going to be looking at the original Raspberry Pi Model B and B+, and the Raspberry Pi Zero. These models all have much more limited CPU power and memory than the Pi 2 and 3, so it will be interesting to see what can be done with them. Read more
