To track down Nodejs processes running on a server first run
netstat -lt
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.
