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.

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.

You can do the same that you were doing with mmencode by doing… Continue reading MMEncode is not available on Linux distros any more.
So I find that my MySQL database is running high on CPU all of a sudden. I optimize the tables etc and no difference. I hunt around the internet to find that there seems to be a problem with this years leap second adjustment which sends MySQL into orbit. The solution reset the date date -s “`date`” and it dropped… Continue reading MySQL pegging CPU after the leap second adjustment.
So since upgrading Perl I am presented with qw warnings coming out of the cron job checking that BackupPC is running. Use of qw(…) as parentheses is deprecated at /usr/share/BackupPC/lib/BackupPC/Storage/Text.pm line 301. Use of qw(…) as parentheses is deprecated at /usr/share/BackupPC/lib/BackupPC/Lib.pm line 1412.

Just bought a new machine and decided to put VISTA on it. Now biggest problem was accessing the shares via smbclient or Samba. Hunted high and low on the net couldnt find anything not specific for VISTA and smbclient. I then looked for windows xp and smbclient and found a post about changing a registry entry. Up to this point… Continue reading Accessing Vista with smbclient
