Running the Anti-Spam SMTP Proxy (ASSP) reliably on a modern Linux server requires a proper service manager. By default, ASSP needs to start as root to bind to privileged mail ports (like port 25), after which it forks and spawns its main worker processes under a non-privileged user like nobody. Using a custom systemd service file allows Linux to seamlessly… Continue reading How to Run ASSP As A Systemd Service With Systemctl
Setting up secure remote access usually feels like a balancing act between security and sheer frustration. For a long time, my server setup relied on Fail2ban throwing up dynamic walls via traditional iptables. It worked, but it was messy, cluttered, and stopping the service felt like waiting for water to boil as thousands of rules were torn down one by… Continue reading Why Tailscale + Firewalld Is My Ultimate Remote Access Stack
Thirty years. That is how long my home network routing infrastructure relied on a monolithic shell script I wrote back in 1996. I crafted it back in the golden era of early Linux packet filtering, packed it with raw configuration lines, and tweaked it over decades as a hobby project to survive moving from ipfwadm to ipchains, and eventually to… Continue reading I Finally Dropped My Custom 1996 iptables Firewall Script—And Why It Was Time
I recently upgraded my system from Fedora 42 to Fedora 43 after Fedora 42 reached end-of-life. When I started ASSP, I received errors indicating that the required Perl modules were incorrect or missing, so I decided to run mod_inst.pl again to reinstall the necessary modules. I downloaded the latest mod_inst.pl from the ASSP website and ran it, but it immediately… Continue reading ASSP mod_inst.pl Error After Upgrading Fedora 42 to 43

For years, I was a loyal Dropbox subscriber. It was the “gold standard” for syncing files, and like most people, I just accepted the monthly fee as a necessary “tech tax.” But as my storage needs grew, so did the bill. When I hit my storage limit and was prompted to upgrade to a more expensive professional tier, I finally… Continue reading Why I fired Dropbox: How Nextcloud is saving me hundreds every year
So I finally got around to installing something so I can host my own calendar and contacts so that data is not shared with the big four corporate companies. As I just need basic calendar and contacts functionality I chose the open source project Radicale. As I have run Fedora to control the house and my private data since 1998… Continue reading Installed Radicale3 for hosting my own calendar and contacts data
Always fails. At first I thought there was an issue with the SD card. Then I read that you have to right-click and run as Administrator from your windows box. I could not get this to work – it never ran. In the end I had to enable the local Administrator on my windows box and login to that account… Continue reading Failed to unpack the windows 10 IoT Core installation package
Not sure what happened to this or why but its no longer available. I used to have a script that used it to convert binary data to text for attachments on emails. Having searched high and low I came up with a new solution – use openssl. You can do the same that you were doing with mmencode by doing… Continue reading MMEncode is not available on Linux distros any more.

Kept getting this error when the windows phone 8.1 emulator “Failed to start the virtual machine because one of the Hyper-V components is not running” Researched a bit and had a few goes and quite a few different solutions but had to manually edit .vmx file which… Continue reading Visual Studio 2015, Windows 10 under VMWare Fusion 7 on a Mac
