SSH, or Secure SHell, is the way in which a modern linux system is managed. Most experienced sysadmins love the direct access and power they get from being able to securely connect to a shell on their systems with relative ease. SSH replaced Telnet somewhere in the 90’s as the remote access protocol of choice,…

RHEL 8 Beta – The podman cometh
I’m working through poking the RHEL8 beta with a pointy stick. In reading through the release notes, and poking around yum, I found that docker is suspiciously missing. For a company so bent on Open Containers, I thought that was pretty odd. So I started to dig a bit. Turns out, containers aren’t gone, just…
Installing the proprietary NVIDIA drivers on Fedora 29
Check out the rest of this story here, if you’re looking for the full tale of woe. This is the final article in my story regarding start to finish, getting my Dell Inspiron from a fresh install of Fedora 29, to a functional laptop. It wasn’t easy. Mostly thanks to the NVIDIA 960M that the…

Adding a local user, in Fedora 29’s Live environment

Discrete video adapters, in Fedora 29, you poor doomed soul
OK, so something posessed me to reinstall my perfectly functional Dell Inspiron 7559 with an Nvidia discrete 960m display adapter. I’ve been through this a few times, and every time it’s been a hassle. The Fedora project has made some changes recently that have made it even trickier. I just went through a fresh install,…
Migrating password hashes from Samba NT4 domain to Active Directory
It’s been a while since I’ve blogged about anything, but today we managed to solve a particularly important problem, that we were having trouble finding answers to, and I wanted to share it so that others might benefit. First, a little back story. We’re currently running a Samba 3 domain, on RHEL, which emulates an…
S3 usage Statistics.
So I’ve recently decided to give S3 a chance, for media storage. Mainly for the Iron Sysadmin Podcast episodes. I’ve gotten one or two comments, not necesarily complaints, that episode downloads seem to tax my server. It came down to bandwidth, and while I have some things to tackle to help that scenario, it was…
Cisco AnyConnect in Gnome on Fedora 25+
For work, I have to use Cisco Anyconnect as a VPN connection. For a long time I would just use the Cisco AnyConnect official client for linux. This software is problematic, buggy, and just plain out gives me heartburn. So one day I came across OpenConenct, which is an open source alternative to the AnyConnect…
