This produces a log of queries the DNS server, I prefer joeqwerty's solution....
Run a packet capture program on the DNS server, start a capture and filter for only DNS, run down the server (a tiny bit), you can simply turn on query logging.

I get a lot of SSH connection attempt from different IP on my server (with different username). 1 to 5 per seconds. It look like a brute force attack. What can I do to prevent that? Block the IP? change the SSH port? Something else?

The ISP hosting a mostly static web site complains when certain users start to hammer the site at around 30 hits/second. The machine slows to a crawl, apparently. The files can be simple pages with a few graphics, to fairly large files. There are other...

I have found that Apache can handle hundreds to thousands of static request per second without being overloaded.

I can't figure this one out. On SQL Server I have a process that is run dozens of times per second (data being sent to the server). The process runs great, processing requests takes between 50ms and 200ms. Then, roughly (but sporadically) once every 1...

Then all incoming.
40,000 messages per second is doable that the drive will fill up in a fraction of a second and crash the system.
