-- Dump all TCP/UDP/RAW/UNIX sockets:
+- Show all TCP/UDP/RAW/UNIX sockets:
 
-`ss -a {{-t/-u/-w/-x}}`
-
-- Show process(es) that using socket:
-
-`ss -p`
+`ss -a {{-t|-u|-w|-x}}`
 
 - Filter TCP sockets by states, only/exclude:
 
 `ss {{state/exclude}} {{bucket/big/connected/synchronized/...}}`
 
-- Filter sockets by address and/or port:
+- Show all TCP sockets connected to the local HTTPS port (443):
 
-`ss -t dst 1.2.3.4:80`
-`ss -u src 127/8`
-`ss -t 'dport >= :1024'`
-`ss -x "src /tmp/.X11-unix/*"`
-`ss -t state established '( dport = :ssh or sport = :ssh )'`
+`ss -t src :{{443}}`
 
-- Only list IPv4 or IPv6 sockets:
+- Show all TCP sockets along with processes connected to a remote ssh port:
 
-`ss {{-4/-6}}`
+`ss -pt dst :{{ssh}}`
+
+- Show all UDP sockets connected on specific source and destination ports:
+
+`ss -u 'sport == :{{source_port}} and dport == :{{destination_port}}'`
+
+- Show all TCP IPv4 sockets locally connected on the subnet 192.168.0.0/16:
+
+`ss -4t src {{192.168/16}}`
