## Symptoms

- * Output of '`ss -t -a`' command (stands for "socket statistics") does not provide output for all TCP sockets (as compared with the output of '`netstat -an`' command.

* Output of '`ss -f inet -t`' command prints "`ss: no socket tables to show with such filter`".

## Cause

The '`ss -t -a`' command replaces the '`netstat -na`' command and is supposed to display all TCP ports in use and their current state by reading the contents of `/proc/net/tcp` file. However, the '`ss -t -a`' command reads only the first 4050 characters ('`wc -c /proc/net/tcp`').
