[swinog] Contacts and Experts for Security Incidents
Hi We are creating an emergency handbook if we would have a critical security incident. Is there someone who can suggest a company which can help to find how the guys hacked the infrastructure and how to fix it? I hope we never have to use it, but be prepared is better Thanks Michael___ swinog mailing list -- swinog@lists.swinog.ch To unsubscribe send an email to swinog-le...@lists.swinog.ch
[swinog] Spamfilter Solution
Hi Can anyone recommend a spamfilter solution: - Cloud hosted (multihomed and HA) - multiple domains - user can release their spam mails - Advanced threat protection - API for different taks - Good Web UI for Logs and configuration We already have one, but the support is not that good anymore, and their blacklisting score is a blackbox... Thanks and cheers Michael___ swinog mailing list -- swinog@lists.swinog.ch To unsubscribe send an email to swinog-le...@lists.swinog.ch

Re: [swinog] Weird Bluewin Server Problem (occasional 550 5.1.1)
Hi Benoit Be Careful mxbw.lb.bluewin.ch seems to be an entry wich is load balanced with different A Records . I've got a different IP after the TTL expired. So you are ending up on different server on the bluewin site. maybe a server in the cluster which has a specific problem, just a guess. Try telnet to the different server and if you can find the specific server -> then try to contact the mailmaster :-) On 24.01.2019 13:54, Benoit Panizzon wrote: Dear List Has anyone else experienced this problem?

Re: [swinog] Coordinated network attacks?
Would me interest too. Hostpoint says their nameservers didn't resolve anymore. Metanet says the problem was coming from an important network device... whatever that means, maybe BGP Core..

Re: [swinog] DNS Admin tool
I've also tried to build some GUI tools for BIND. It's not that easy. I was only able to build some Perl Scripts so that people with low Linux skills can manage the zones.. In the end we changed to PowerDNS and built or own GUI with PHP/MySQL. Our Users are happy with it and they don't need any skills except of what they put in their zones :-) But we've only about 800 Zones, don't know how good PowerDNS scales in a huge Environment ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
