    On specifying the following netstat command, some column headers are seen for which I have not been able to locate a description of, in the documentation:

    netstat -an|more

    Active Internet connections (including servers)

    Proto Recv-Q Send-Q Local Address Foreign Address (state)

    tcp4 0 0 123.456.789.012.3456 012.345.678.901.2345 ESTABLISHED

    Any idea what the Recv-Q and Send-Q pertain to??

    Typically, when the system is listening on port 3456 (note: not a real port number that we currently utilize), both Recv-Q and Send-Q are 0 (zero).

    However, when we are in a CLOSE_WAIT state, the Recv-Q column has values other than zero (almost all the time). I see a lot of 30's, some 40's, a few 60's........

    Anybody know what the correlation of the Recv-Q value is to the CLOSE_WAIT state?

    TIA
