Changing the locale in Ubuntu Server

When logging into any cPanel server via SSH from an Ubuntu jump server I was seeing some strange warnings from Perl which I didn’t see when logging in from my laptop running macOS: perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = “C.UTF-8” are supported and installed on...

Decrypting an APFS volume from the Terminal

I’ve been playing about with a Hackintosh desktop running High Sierra, but run into an interesting problem – the FileVault Preboot loader which asks you for the password to decrypt the APFS volume doesn’t recognise the USB keyboard by default. Apparently there are ways to fix this by building the necessary drivers and inserting them into the Preboot volume, but as...

Building Bareos RPMs on Ubuntu 16.04

Building Bareos RPMs on CentOS 6 & 7

Bareos (Backup Archiving Recovery Open Sourced) is a popular open source backup system originally forked from the Bacula project, but they only publicly publish packages for the first release of each major version; updates are reserved for paying customers. The source code is available on GitHub however, so you can pretty easily build your own packages, even if exactly how...

Missing Junk mailbox in Apple Mail

When setting up a new MacBook Pro recently, I was impressed that all of my mail account settings were synced over via iCloud, but somewhat surprised and confused to find that the “Junk” mailbox for all accounts was missing. I couldn’t find the “Junk” mailbox anywhere – it wasn’t in the list of special folders (Drafts, Sent, Trash etc.) with...

Parallels Plesk hanging on login

I recently came across a strange problem when setting up a new Windows Server running Parallels Plesk 12. Everything was working fine to being with, and then suddenly Parallels Plesk started behaving strangely.

SuperMicro ipmicfg utility on Linux

SuperMicro have a nice little utility called ipmicfg, which can be used to interact with the IPMI BMC from within your operating system. This can do all sorts of things with the IPMI BMC, however it’s really useful if you want to change the IP address details on the IPMI card without rebooting your system and going into the BIOS...

Extract the tarball, open up httpd.spec in your favourite text editor and scroll down until you find a...
