I’m tried to find ss.html anywhere in debian packages, but as you can see found nothing.

# apt-file search ss.html | grep -w ‘ss.html’
mednafen: /usr/share/doc/mednafen/ss.html
python-pycryptodome-doc: /usr/share/doc/python-pycryptodome-doc/html/src/protocol/ss.html

Thanks for the examples. Noticed a few things.

Example 5 seems to have incorrect text. [1] The actual output shows dnsmasq is pid 1347 not 1299. [2]

Example 7 seems to have cutoff text. [3]

Example 9 has text saying the command shows all TCP “connected” states [4] however the command example below the text is only showing connections in the established state [5].

[1]
“In the above output the last column contains the process name and pid. In this example dnsmasq is the process name and 1299 is the pid.”

[2]
LISTEN 0 5 127.0.1.1:domain *:* users:((“dnsmasq”,1347,5))

[3]
“The timer information tells how long with ”

[4]
“To display all Ipv4 tcp sockets that are in “connected” state.”

[5]
$ ss -t4 state established

My experience is that on a RHEL 6 system, netstat -anp takes 0.161 seconds to run, while ss -np takes 6.7 seconds. If by faster you really mean 416 times slower, then I agree.
