The output of the 'ss -a' command does not show all ports and their current state
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').
