https://easydns.com/blog/2026/04/18/we-screwed-up-and-we-own-it-the-eth-limo-shtshow-is-on-us/

As this was a social engineering attack, the attacker could have changed the DS-record in the “limo" TLD as well, but did not know or forgot …

#DNSSEC #DNS

We screwed up and we own it: The eth.limo sh*tshow is on us. - easyDNS
easyDNS

We screwed up and we own it: The eth.limo sh*tshow is on us. - easyDNS

It's never a good sign when you wake up on a Saturday morning and realize your phone has been blowing up since about 4am. Instead of spewing out the usual GPT-generated platitudes around "we take your security very seriously" (even though that is true), I'm just going to lay it…

A new version of EtherSLIP (Ethernet over SLIP packet driver for MS-DOS) is available, two bugs fixed by Michael Brutman.

The new version can be found at
https://www.brutman.com/Device_Drivers/packet_drivers/EtherSlip_v11.8.zip

More details about the bugs are in the ZIP archive, which also includes the updated source code.

Does anyone run the YADIFA DNS Server (https://yadifa.eu/) in production? I would be interested in stories about this piece of open source software. How widespread is it deployed?

es gibt neue BIND 9 Versionen, in denen wurden Sicherheitsprobleme vorheriger Versionen gefixed:

https://kb.isc.org/docs/cve-2026-1519
https://kb.isc.org/docs/cve-2026-3104
https://kb.isc.org/docs/cve-2026-3119
https://kb.isc.org/docs/cve-2026-3591

u.a. Denial-of-Service bei BIND 9 Revolvern (CPU-Auslastung, Speicherauslastung, Crash).

Die ISC-Repositories haben die neuen Versionen

- 9.18.47
- 9.20.21

Ich empfehle ein Update, sobald die neuen BIND 9 Versionen in den Repositories der Linux-Distribution verfügbar ist.

@me_ Hallo Michael, ja sehr gerne, besonders da ich auf der GUUG Deinen Vortrag verpasst habe und den gerne “live” sehen würde. Kann ich den Abstract von der GUUG Webseite/Pretalx übernehmen. Hast Du für den Vortrag eine Präferenz für den Tag (Fri/Sa/So)?

@miek@mastodon.cloud TTL mismatch kills the redundancy. Here, after 300 seconds only the 2nd IP with TTL 86400 stays in the cache (for 86100 seconds).
