Was man alles so bei einer Webserver-Loganalyse herausfindet.
- je älter die Domain, umso mehr rauscht sie
- #Wildcard für eine #Domain verstärkt das Rauschen
- Bots versuchen bei 403 oder 404 einen #ReverseDNS und landen dann wieder auf dem Server
Daraus folgt: Wildcard löschen und nur genutzte Subdomains in den #Nameserver packen. Wieder was gelernt. #server #apache #logs

112 – Was sind Nameserver und Cloudflare

Nameserver sind entscheidend für die Funktion des Internets, da sie die Benutzerfreundlichkeit durch die Umwandlung von leicht merkbaren Domainnamen in numerische IP-Adressen sicherstellen. Ohne Nameserver müssten Benutzer sich IP-Adressen merken, um Websites zu besuchen, was sehr unpraktisch wäre.

Just added 2 more name servers for one of my domains. Why? Why not :P

```

ns1.first-ns.de.
colin.sahilister.net.
ns2.albony.in.
ns4.he.net.
marvin.sahilister.net.

#authoritative #nameserver #dns

So, while working on some #botnet research, I discovered a domain for which a #nameserver was configured with the name ns1.nulled-ns.com and ns2.nulled-ns.com. As more I figure out about this unknown authoritative nameserver, as more I am convinced that the entire purpose of the nameserver is to provide name services for malicious domain names, such as #c2 or #phishing domain names.

Happy about anyone commenting, or reaching out to me with more insights.

Cheers!

As of today, #DNS4EU is live. A project that started somewhat of 3 years ago. Now, it's public and live, promising secure and resilient service to #EU citizens, strengthening the #European #cyberresiliency .

More here.

I queried my own domain name out of interest. The EU protective resolver resolves in 340 ms, whereas #Cloudflare and #Quad9 both resolve within 50 ms.

The unfiltered resolution however resolves within 50 ms as well, revealing that the filtering introduces a slight performance penalty.

habe heute nachmittag in meinen autoritativen #Nameserver (#bind) eingefügt:

rate-limit {
  responses-per-second 5;
  window 5;
  slip 0;
  exempt-clients {
    alle_meine_freunde;
  };
  log-only no;
};
logging {
  channel rate-limit_file {
    file "/var/log/rate-limit.log" versions 3 size 5m;
    severity dynamic;
    print-time yes;
  };
  category rate-limit { rate-limit_file; };
};

Meine Fresse, was da abgeht!
(in Wirklichkeit steht da natürlich noch viel mehr)

Wie dumm ist eigentlich die Idee, einen der secondary authoritative #nameserver für eine Domain nur per #ipv6 erreichbar zu haben?

Kann es sein, dass die #telekom #nameserver #dns die #TTL nicht unbedingt befolgen?

Ich habe (#AusGruenden) hier einen RR auf 60 Sekunden gesetzt und irgendwie hat's jetzt (ziemlich genau?!) eine Stunde gedauert, bis die Updates an den LTE-VPN-Knoten durch waren...
