getting source code for linux's /bin/ss tool

Question

ss tool is analogue to netstat. ss uses NETLINK libraries documented really bad (man 7 netlink). I couldn't find online how properly use NETLINK_INET_DIAG feature. Source code for ss tool would help, but I can't find it either. Any advice would be really appreciated.

Answer 1

The package that you are searching for is: iproute

Try apt-get source iproute instead. You will find the source code in misc/ss.c.

NOTE: You can use the ubuntu packages search tool and go to "Search the contents of packages"
