A "Linux systems specialist", did claim my previous business card and did so from 2001 to May 2013. Now it says "Senior System Administrator" in another company, Stonesoft, which is part of McAfee/Intel Security.

My heart also has a place for FreeBSD.

comment install-man5 Error 1 after running 'make install' after compiling NUT (Network UPS Tools)
Probably the actual error has happened during make and not make install phase. I guess your system is lacking so documentation/man page related dev tools.

comment Docker debian slow dns resolve
Are you sure it's the DNS which is slow and not something else? Perhaps the MTU is wrong and causes your TCP traffic being much slower than it should be? Capture the traffic with tcpdump or wireshark and see how it goes.

comment Analyze logs after hack
Your log line just states that the HTTP referer is set to jjbabskoe.ru. Could it be that the jjbabskoe.ru actually is linking to your site for whatever reason? Or that a random web surfer had decided to surf from porn site to your site, making that referer appear? Or just some bot spam?

comment How to release the physical and virtual memory used from the mysql server?
I would go and check the PHP code and the SQL queries it generates first. Enable MySQL query logging if in doubt. It can also be that the SQL queries are efficient but the PHP script is doing something memory-hungry, perhaps by design, perhaps because of a bug.

comment How to release the physical and virtual memory used from the mysql server?
Are you sure your PHP scripts (or some heavy SQL queries) are not suddenly allocating lots and lots of memory for a while? That would force your system to swap and whenever the heavy query or PHP script (I suspect the PHP scripts) ends, the memory is released and shown as free RAM & used swap. Fix that somehow. :)

comment Ubuntu Server 14.04LTS Swappiness for server with 16GB memory
Higher swappiness causes rarely used processes to be swapped to disk very early, so they won't use the precious RAM. If they would use RAM unnecessarily with the low swappiness value, the server would be swapping much more whenever the memory pressure hits because it would have to swap the idle processes out of the way.

Keeping stuff in memory is much faster than load it again from the disk. Don't be afraid of the amount of used memory, free RAM is wasted RAM. Linux is very smart in its memory use.

Uh, yeah, snmptrapd receives the traps. Anyway the snmptrap is just a client program.

comment VPS Unknown Read/Write
I guess you have way too many httpd processes configured and if there's a database server running on the same host, too, then the one gig of RAM is not very much as we can see from the swap usage. Or, then it's just bad code. That's all the magic we can use right now here.

comment how to do synchronization with multiple servers?
Many of those "enterprise cluster file systems" suck donkey balls whenever your filesystem contains (tens of) millions of small files, they start spending all the time just synchronizing the state and the performance drop is abysmal. Just a warning.
