kernel: possible SYN flooding on port 655. Sending cookies.
On a Linux Server running tincd I noticed the following log message in
/var/log/messages
kernel: possible SYN flooding on port 655. Sending cookies.
I found this on the web:
If SYN cookies are enabled, then the kernel doesn't track half open
connections at all. Instead it knows from the sequence number in the
following ACK datagram that the ACK very probably follows a SYN and a
SYN-ACK.
