Fail2ban with Gitea

pubsub.slavino.sk / warlord0blog · Monday, 9 January, 2023 - 14:21

I noticed a bot had decided to target our Gitea service, so thought of putting it into fail2ban to lock it down. Turned out this wasn’t as straight forward as I’d hoped. Adding to the fail2ban was not a simple task, as Gitea is in a docker container. First thing required is to change the &ellipsisRead the full post »

Git Hooks

pubsub.slavino.sk / warlord0blog · Monday, 5 December, 2022 - 08:27

I wanted to ensure I wasn’t pushing unencrypted data onto our Git repo. It’s set as private anyhow, but the repo I’m using is for our Ansible library. It contains all kinds of details about the builds of equipment and software delivery, that would be a risk. How do I ensure that I don’t push &ellipsisRead the full post »

Holy Guacamole!

Apache Guacamole – not the answer I was looking for, but impressive. I wanted to get a remote desktop session to a client machine to support them in the session they are currently working in. On my journey, I encountered guacamole and installed it. Have to say I’m impressed, but what it isn’t is a &ellipsisRead the full post »

sudo-ldap Fails to Authenticate

pubsub.slavino.sk / warlord0blog · Wednesday, 16 November, 2022 - 11:39

I mainly use two Linux distros – Manjaro and Debian (or Debian based distro Mint). For most remote workers, I rolled out Manjaro with caching authentication using SSSD. But this week has been frustrating as I’m delivering remote users on Linux Mint. First step of the process is getting the users authenticating using LDAP, add &ellipsisRead the full post »

Nginx Container with Custom Modules

pubsub.slavino.sk / warlord0blog · Tuesday, 8 November, 2022 - 12:41

The dev team wanted a version of Nginx that included some custom modules. I’ve previously built custom Nginx on bare metal, but this time it wanted to be in docker. To build the required modules, you need to compile them using a tarball Nginx. But I don’t necessarily want to run a custom Nginx just &ellipsisRead the full post »
