Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have a high load long TCP connections server and I had to tweak sysctl to make sure I get no errors, At the moment I get no errors, But I think i might get TCP drops without errors.

Here is sysctl -a on my server http://pastebin.com/z6naLZi6

and netstat -s http://pastebin.com/8MZ6DcSz

What I find odd in the netstat-s file:

31 SYN cookies sent
30 SYN cookies received
61605 invalid SYN cookies received
TCP:
14408 failed connection attempts
Udp:
103527 packets received
6594462 packets to unknown port received.

My question: Is there anything obviously wrong in here? Can you suggest what should I look for fixing if there is? Very much appreciated!
