I am using netstat to retrieve the maximum size of the syn backlog from each listening socket. I read the following from the documentation:
Send-Q
Established: The count of bytes not acknowledged by the remote host.
Listening: Since Kernel 2.6.18 this column contains the maximum size of the syn backlog
However, when I run netstat -ntpl, the Send-Q column only contains zeroes, while the output of ss -ntpl contains the expected results.
Although I know that ss should be used instead of netstat, why do the results differ between netstat and ss and how can I get the expected results with netstat?
