I'm not successful filtering on the connection state associated with a port.
None of the syntax variations I have tried have been successful.
If I remove the STATE specifier, matches are found.
There are multiple hosts connecting to the same port:
ESTAB 0 0 10.160.8.130:61617 10.160.8.132:57765
ESTAB 0 0 10.160.8.130:61617 10.160.8.132:57766
ESTAB 0 0 10.160.8.130:61617 10.160.8.132:57768
ESTAB 0 0 10.160.8.130:61617 10.160.8.133:45096
ESTAB 0 0 10.160.8.130:61617 10.160.8.133:45104
ESTAB 0 0 10.160.8.130:61617 10.160.8.133:45107
ESTAB 0 0 10.160.8.130:61617 130.118.4.2:36141
ESTAB 0 0 10.160.8.130:61617 130.118.4.2:36150
ESTAB 0 0 10.160.8.130:61617 130.118.4.2:36151
ESTAB 0 0 10.160.8.130:61617 136.177.16.3:34320
ESTAB 0 0 10.160.8.130:61617 136.177.16.3:34321
ESTAB 0 0 10.160.8.130:61617 136.177.16.3:34324
ESTAB 0 0 10.160.8.130:61617 137.227.240.32:50726
ESTAB 0 0 10.160.8.130:61617 137.227.240.32:50727
ESTAB 0 0 10.160.8.130:61617 137.227.240.32:50729
LISTEN 0 0 *:61617 *:*
I've set up several port monitoring specifications, but none of them
match the state (the first example where no state is specified
succeeds):
PORT LOCAL=%[:](61617) REMOTE=%10.160.8.132 MIN=3 MAX=3 COLOR=yellow
TEXT=ActiveMQ-DHCP
PORT LOCAL=%[:](61617) REMOTE=%10.160.8.133 STATE=ESTABLISHED MIN=3
MAX=3 COLOR=yellow TEXT=ActiveMQ-nsp.er
PORT LOCAL=%[:](61617) REMOTE=%136.177.16.3 STATE=ESTAB MIN=3 MAX=3
COLOR=yellow TEXT=ActiveMQ-ns.cr
PORT LOCAL=%[:](61617) REMOTE=%137.227.240.32 STATE=%ESTAB MIN=3 MAX=3
COLOR=yellow TEXT=ActiveMQ-ns.er
PORT LOCAL=%[:](61617) REMOTE=%130.118.4.2 STATE=%ESTAB* MIN=3
MAX=3 COLOR=yellow TEXT=ActiveMQ-ns.wr
Note: On this server netstat does not exist and ss is being used,.
Observation: Discovering the syntax for REMOTE was trial and error.
Specifying the IP address alone did not work, and I found no examples
for the type of filtering above.
