comment Why are my passive checks not processed?
netstat|wc -l gives 33. I don't think that's too much.

comment Why are my passive checks not processed?
The directory is owned by nagios:nagios. When the nagios.cmd is written (it gets removed when I restart Nagios), it will be owned by root:root. I already tried changing the ownership to nagios:nagios after it is created, but that has no effect on the issue.

@TheFiddlerWins I assume the parens are fine, because active checks work. How can I check the connections?

comment Why are my passive checks not processed?
@Keith: I'm using my own handler, but I also used snmptt before. With identical results. I initially followed askaralikhan.blogspot.de/2010/12/… and traps were visible in Nagios. I then started extending the concept and adding my own code, now nothing works :P

@Keith: I'm running with the highest log level output and I don't see anything relating to those service checks in the debug log. The "normal" log only lists the CURRENT SERVICE STATE after log rotation.

comment Can a DNS client distinguish if the answer they received was based on a wildcard record or a specific match?
Sweet. I learned a new dig command :) Thank you very much!

@yoonix: Argh, of course. They can transfer the whole zone :P That's probably the reason

The zone is fm.mg. Feel free to compare queries against ns1.hartwig-at.de and 8.8.8.8. Maybe you can enlighten me :P

@HåkanLindqvist: Yes. The zone contains only 1 A/AAAA record for www and the wildcard. The wildcard is what I changed.

@yoonix: So, why am I seeing the old IP when I query a random name on that zone? Random, as in 5571f913b637ef1f27f14fb5, nothing that exists as an entry. Shouldn't that always cause a query to our servers? As mentioned, when I query the same name on our servers, I get the new IP.

comment Can VMs offload checksum calculations to the physical NIC when I disable checksum offload on the host?
That being said, it seems like one can adjust task offloading via the registry. Which makes this task a lot easier. So the question will probably be redundant soon.

comment Can VMs offload checksum calculations to the physical NIC when I disable checksum offload on the host?
@joeqwerty: Yes, this recommendation is coming from the vendor. I've heard the same recommendation previously from other vendors, directly from Microsoft and also from hardware vendors when we were troubleshooting issues in that network. I'm not quite sure how re-enabling the settings now would give me any more insights. I see failures now and I would see failures then. If I disable offload on 1 VM, it could take weeks until I see a failure. How long should I wait until I can reach a conclusion? If the feature is fully disabled everywhere, I could reach a conclusion much faster.

Well, it will cost a lot of time going through each VM and changing the settings in their NIC driver. If it won't make a difference, I'd like to avoid it. Especially since, if it doesn't make a difference, then I'd have to change it back.

comment How do I fix black window color after system update?
Yeah, I really don't want to install Desktop Experience on the server. The current state impacts being able to manage the server because you can't read text on title bars, which is at least very inconvenient.

comment Why does nginx redirect to URLs with a trailing slash?
@MichaelHampton: I know there aren't, which is why I'm confused. When I tell GitHub to redeliver the payload, I don't even see any HTTP requests in the application log, which is why I assumed the problem would be with nginx. I'll definitely look into all possibilities though.

comment Why is it so important to backup your transaction log?
@TomTom: Sorry, I'm very new to Stack Exchange. I clearly misunderstood what "Enterprise storage, backup, and disaster recovery" covers. Thanks for showing me the way.

@frupfrup: ArcServe has an option to truncate SQL Server transaction logs, which we have enabled. Thanks though :)
