Why TCP RST packet generated what are the possible cause

when TCP RST packet generated? what are the possible cause of generation on 开发者_StackOverflow社区TCP RST packet?

The RST flag is used to signal any kind of error and terminate the connection.

• If you send a packet with a wrong ACK, you will get a RST
• If you don't acknowledge data in a timely manner, you get a RST

Basically, if you do anything wrong, a TCP will send a RST and terminate the connection.

It is also possible that Linux Kernel sent these RSTs.
