Hi,
When the half-open TCP connection queue is full and syn cookies are enabled, you get a message like "kernel: possible SYN flooding on port 2710. Sending cookies."
However when syn cookies are disabled, you don't get any message (in kern.log), although connections to your server are timing out.
Could such a message be added?
Maybe with a suggestion to increase the size of that queue or to enable syn cookies.
That should be discussed with the upstream developers, the Debian BTS is not
the best way to change this. You can reach them at linux-net@xxxxxxxxxxxxxxx
Hi Linux net devs,
See this issue reported in the Debian BTS.
Wrong list. You want linux-netdev.
