Quick post…. If you have a need to customise the PS1 prompt on your linux machine(s) take a look here https://www.tecmint.com/customize-bash-colors-terminal-prompt-linux/ to see how you can customise the font colour, background colour and also provide some font level of text formatting. It explains it in a nice clear way so even I can understand it. […]
It has been a very log time since I’ve posted anything and thought it was about time I did. So here goes… This article will briefly walk through the steps to setup an OpenVPN service running on a recently patched Cent OS 7.9 server and using a Fedora based OpenVPN client, where we look at […]
I have had to work around this issue for some time now (as have many other Nextcloud and KeeWeb users). Apparently from version 1.10 of NextCloud, the regex that had work flawlessly before no longer worked. For those who are using Nextcloud and KeeWeb (I assume on any OS) and accessing the keepass database file […]
I’ve been working on deploying a new email service based around postfix and dovecot as the imap server (basically the standard services that come with RHEL, CentOS and Fedora) and one of the main things to focus on has been improving security where possible. I happened to find a pretty useful web site for picking […]
Recently I’ve upgraded a test vcenter appliance to 6.7 update 1 and found that a long standing issue is, well, an even longer standing issue. I was attempting to deploy an OVA file via the vCenter HTML5 (and subsequently the Flex) client and was confronted with the following warning; The operation failed for an undetermined […]
I have to admit this isn’t a question that crops up all that often, but given what I have been through over recent months, I thought I’d share with the world. Lets start from the beginning… What are raw devices? Raw devices, are used when there is a need to present underlying storage devices as […]
In the past I have looked at, adding Sender Policy Framework (SPF) which looks at the bounce address of an email, I have also looked at SenderID which looks at the FROM address part of the email header, and then there was Domain Keys Identified Mail (DKIM) which signs your emails to confirm that they […]
Normally, I perform my OS upgrades by way of a clean install. This time round though, I thought I’d give the upgrade process a try, given Fedora are pushing it quite a lot this time round. The actually process took about 30-35 minutes on my machine, and that’s including the time required to download the […]
I have embraced Red Hat Satellite server in a big way over the past year and try to use it wherever possible though not for everything. One of the features I started using to simply life whilst I look at other configuration management systems, was Configuration Channels. These allow you to provide a central repository […]
I’ve recently been working on a project to deploy a couple of Pure Storage Flash Array //M10‘s, and rather than using Fiber Channel we opted for the 10Gb Ethernet (admittedly for reasons of cost) and using iSCSI as the transport mechanism. Whenever you read up on iSCSI (and NFS for that matter) there inevitably ends […]
