tcp

Suppose that a given TCP fragment is fragmented into two IP datagrams, and that the first datagram arrives to the TCP server, but the second datagram never arrives.

After a certain amount of time the TCP server sends a keepalive, and determines that the client is alive. What does the TCP server then do with this first datagram? Does is wait for the second datagram to arrive, or does it discard the first datagram?

I'm suspecting an attack, but not sure. Intermittently, the web server will stop responding. When this happens… >>> More
