• Nicolas Fränkel ☛ Broadcast devices' name on the local network

  With years, I accumulated devices on my local network, which in general run on Linux. I meticulously added them to my /etc/hosts/ file, so as not to remember their IP. Something puzzled me, though: my Synology NAS was readily available as nas.local on the network, without doing anything. I have close to zero skills in system administration, so here are my findings.

• Darren Goossens ☛ Shutdown Linux computer through RDP — restart issues

  So systemctl is probably using $0 (the command line argument that holds the name of the program itself) to then do the action and modify its behaviour to mimic the old pre-systemd shutdown, reboot, halt etc scripts. Is there a difference between: [...]

• Alex Schroeder ☛ 2025-06-16 Ban autonomous systems

  More people have been working on blocking whole ranges of IP numbers, since that catches hosting providers that give bots access to the whole range they control. The bots switch IP numbers all the time so a filter based on IP numbers won’t catch them. But if we can determine their autonomous system number (ASN), we can not only block an IP number range, we can block all the IP number rangers the ASN controls.

  Now, since these hosting providers also host nice things like other fediverse instances, I don’t want to block them forever. I want to block them for 10min, and if they continue after a few of these shorter blocks, I want to block them for a week. Hopefully, their clients have ended their Internet slurping and things are back to normal. This is how fail2ban works, but only for individual IP numbers.

  I want code that bridges this gap.

• Dan Langille ☛ Steps for adding a new laptop

  Now, you might ask, why am I setting this host up with a new host name, ssh-key, creds, etc. Go head ask. I’ll wait.

  It’s because I’ll have both laptops running at the same time and I’m not a fan of sharing creds, even with myself. It also means that when the old laptop is disposed of, the items to change/delete from configurations is clearly distinct.

• Brad Taunt ☛ Starlink, OpenWrt, and Eeros... Oh My!

  I got my hands on a D-Link DIR-878 A1 Router (say that ten times fast…), which supports OpenWrt. If you’ve never heard of OpenWrt before you should check it out. It’s an incredible project and helps bring life into a lot of older embedded devices that have since lost support from their respective companies. Any projects that help reduce e-waste are good in my books!
