    Docker has, for a lot of cases, become the go to way to install and run certain services. Docker is a container system which means it comes with all the advantages of containers such as ease of installation, resource management and security. Docker is also fairly low overhead so it’s possible to run a number…

    In an earlier article I configured a Raspberry Pi to accept SSH logins using keys rather than passwords all the while working from a Windows 10 machine. In this article I’ll do the same but working from another Raspberry Pi machine. Although I’m using a Raspberry Pi here this process, or something very much like…

    This guide assumes you have a Raspberry Pi already installed e.g. you can log in and see either a command prompt or the desktop. This guide will make use of the command line. I’m setting up a headless server as I write this and working on a Windows 10 machine. All key generation and configuration…

    I’m running a MikroTik RouterBOARD 962UiGS-5HacT2HnT with a level 4 license. This set up should work on any level 3 or higher licensed version of RouterOS which I think is now all of them. I’m setting this up using WinBox, it can also be done using the web interface and the command line. Add an…

    I recently treated myself to a new hard drive as I was running out of space. I decided to go with a Seagate external drive and shuck it for my server. Shucking is the act of removing a drive from an eternal drive enclosure and fitting it somewhere else such as a NAS. I’ve not…

    I’ve not built my own PC in a vary long time so I thought it would be prudent to do a little research. When I last built a machine manuals were sparse now they are down right non-existent it seems. The notes below cover the bits that I found to be not entirely obvious.

    I’ve got a couple of old Dell PowerEdge 860 servers. They are nothing to write home about but they are functional and good enough for playing around with (I’m investigating KVM and Xen virtualization at the moment). What I need to do though is install from a USB as I don’t have any CD’s to…

    I was recently faced with the task of having to apply updates to an server running ESXi 5. Now, you would think that this would be a pretty simple job but it actually turned out to be more difficult that I would have though. The main problem was that I couldn’t find any concise instructions.…

    I’ve been installing a new ESXi 5 based VMWare server recently. The machine contains an LSI MegaRAID 9260-4i RAID card and four decent sized disks. The host operating system installed fine and I thought everything was going well until I got almost to the point of completion when I went to check that error reporting…

    I was recently faced with the task of upgrading the firmware on an LSI MegaRAID 9260-4i RAID card. Normally this would be a fairly simple process as LSI provide an easy to use command line utility called MegaCLI. The difficulty was using this utility on a machine that was running VMWare ESXi 5 Update 1.…

    MikroTik release updated versions of RouterOS on a fairly regular basis and it is normally a good idea to update your router when they become available. Upgrading is a fairly painless process but I found the instructions given on the website were a little out of date.

    I recently upgraded from RouterOS V5.13 to V5.16. The interface is a bit nice to look at (especially in the web configuration tool) and there is now a quick setup window in WinBox. The only downside of the upgrade is that all of a sudden my Internet connection stopped working.
