To track down Nodejs processes running on a server first run
to list the ports that applications are listening on. This may show port 31044 is listening, for example.
Next, find the processes that are listening on those ports with
netstat -anp 2> /dev/null | grep :31044
This may return a process id like 7392/server.js – then look up the details of this process id with
ps -ef | grep 7392
to find the location of the Node.js server that is servicing these requests.
