We all love maxscale for running our mariadb galara clusters! But how to make the best of it. The temptation most people have is to have one, or maybe two maxscale servers connecting into the database cluster, but I’ve found a way that works really well. On each server that connects to the database cluster, […]
The secret that can break servers
So I run a NextCloud installation called wolf-cloud. https://cloud.wolf-grid.com Yesterday the OpenOffice server stopped talking to the nextcloud server complaining it had a token issue, plus when I went to do a proxmox backup of the nextcloud server it hung. I thought at first we had some kind of issue with proxmox or the hardware. […]
Nasty hackers foiled with fail2ban
So I often glance at the system logs of my proxmox vms / servers – it’s great fun watching the hack attempts and you will get a lot. Today I was looking and I saw this:- As you can see – someone is repeatedly trying to poke my server. Although they are not getting in […]
Tailscale your own private network
So I have backup servers, they are set up in fact to mirror the live servers, so I need them on the internet but only with a static IP for my use. Tailscale installed on my local machine and the servers on the network allows me to set up such a network. It works fine […]
Why use MINO object storage?
Let’s face it folks hosting anything on the major providers is very expensive, overly expensive when you can build it yourself. MINO object storage I love, I’ve got a big deployment of it and at the moment it’s over 1.4 million objects. It’s fast and very stable. You can have multi-server, multi-drive setups across multiple […]
A bit of linux fun.
Install sl apt-get install sl type sl <enter> instead of ls Thank me later
Oh no I lost my linux username?!
It just literally happend to me. I was just going to rewew a certificate and I realised that I’d not accessed the server for a year! How cool is that, the server has been up for nearly a year. Anyway went to login, couldn’t remember my login name. So by design this server is one […]
Email bouncy bouncy
So a friend of mine was telling me that when his company sent mailshots half the emails were bouncing back. Cleverly I was immediately pointing him towards his SPF records in the DNS. I was like I bet it’s not set up! SO he comes back to me and his IT Helpdesk confirmed it was […]
VPN Static IP’s an alternative to dyndns.
So under my desk here I have an old tower, it’s kinda nice but not over powered so I decided to set it up as a Proxmox node on my cluster (which is in Germany!). Because I’m in a shared office I’m not even sure if they can provide dedicated IP and as it was […]
Welcome and Hello
A long time ago in a galaxy far away I had a big blog called Netbeansboy which kind of disappeared into the ether. So I thought it would be kind of fun to set up a new Tech blog covering some of the crazy things I found along my journey. I have built and run […]
