I use ss in iproute package to list sockets statistics. Using -p option can give me process information. Do you know what does the numbers shown mean? I can see that the first one is pid but not the last one. Thanks.

Sample output:

ESTAB 0 0 192.168.1.2:59246 124.40.42.38:www users:(("gweather-applet",1922,23))

ESTAB 0 0 192.168.1.2:42612 72.14.213.16:imaps users:(("thunderbird-bin",5553,45))
