      Ventoy – One Stick to Boot them All

      pubsub.slavino.sk / warlord0blog · Tuesday, 31 January, 2023 - 18:28 edit

    I regularly end up writing a bootable USB to start a different version of Linux or different distro. Then I came across Ventoy. Once a USB stick is installed with Ventoy any ISO that you copy onto the stick appears in the Ventoy boot menu. Select the ISO and it boots! Just copy an ISO &ellipsisRead the full post »

      Video Conferencing Screen Sharing

      pubsub.slavino.sk / warlord0blog · Friday, 27 January, 2023 - 13:45 edit

    The behaviour of my browser seemed to have changed, and no longer lets me share a screen. I end up with a presentation of three black screens to share, and no one gets to see the full screen. I also noticed some missing applications for sharing a window. Searching the net, I found a Google &ellipsisRead the full post »

      Remote CUPS Server over SSH

      pubsub.slavino.sk / warlord0blog · Saturday, 21 January, 2023 - 19:09 edit

    Hosting a customer’s web service for ERP systems means the hosted system has limited options of sending printable material to the end user. Usually it involves printing a web page from the browser, or having the server convert the document to a PDF that the user then downloads and is able to print locally. When &ellipsisRead the full post »

      Fail2ban with Gitea

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

    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 edit

    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!

      pubsub.slavino.sk / warlord0blog · Friday, 18 November, 2022 - 11:29 edit

    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 »
