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
and netstat -s
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!
