SYN-Wait timer: When sending packets with the SYN flag, TCP starts the SYN-Wait timer.
If no response is received before the SYN-Wait timer expires, the TCP connection ends.
The timeout interval of the TCP SYN-Wait timer is an integer that ranges from 2 to 600,
in seconds. By default, the value is 75s.
FIN-Wait timer: When the TCP connection status changes from FIN_WAIT_1 to
FIN_WAIT_2, the FIN-Wait timer is enabled. If no packet with the FIN flag is received
before the FIN-Wait timer expires, the TCP connection ends. The timeout interval of the
TCP FIN-Wait timer is an integer that ranges from 76 to 3600, in seconds. By default, the
value is 675s.
Size of the packet receive or transmit buffer: The value is an integer that ranges from 1 to
