      Adguard or Pihole?

      pubsub.slavino.sk / warlord0blog · Thursday, 27 April - 16:49 edit

    I guess this could fall under the banner of a privateer project. I’m trying to banish adverts from streaming devices and wanted to see if Adguard or Pihole could help. Both of them operate the same way. They act as a DNS server and when a client makes a request for an address, they check &ellipsisRead the full post »

      pubsub.slavino.sk / warlord0blog · Thursday, 30 March - 07:07 edit

    Over time I’ve encountered some great pieces of Free and Open Source Software. I just wanted to list a few noteworthy products in a single place I can refer to – in no particular order. NHAS/WAG – Adds 2FA/MFA to WireGuard VPN’s allinurl/goaccess – Real Time Nginx log analysis

      SSSD and SUDOers

      pubsub.slavino.sk / warlord0blog · Thursday, 9 March, 2023 - 17:59 edit

    All our remote users are using LDAP cached credentials using SSSD. This works really well for users that transition online to offline, with one failing. When they attempt to use sudo to elevate permissions to carry out a privileged operation. For the longest time I could not get this working. I searched LDAP and compared &ellipsisRead the full post »

      ldapsearch and base64 decoding

      pubsub.slavino.sk / warlord0blog · Tuesday, 21 February, 2023 - 16:03 edit

    I recently had to do an ldapsearch/ldbsearch that returned some base64 encoded results. I can go decode them using base63 -d line by line, but I found this magic spell that did it for me. I have no real clue how it works, it’s written in Perl and that is a dark art to me. &ellipsisRead the full post »

      Extracting Graphs from Grafana

      pubsub.slavino.sk / warlord0blog · Tuesday, 14 February, 2023 - 12:35 edit

    The Grafana dashboards are a really nice interactive display of metrics. What we want to do is take those graphs from a dashboard and share them on a static monthly report. I found some advice in how to grab shared output using date epochs. This enables me to dynamically specify a URL to grab a &ellipsisRead the full post »

      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 »
