Where is my socket server on AWS EC2 instance?

Question

I have taken over a project that has an AWS ec2 elasticbeanstalk instance running a socket.io server.

I have logged in via and done the following steps.

1. SSH in
2. cd /var directory.
3. ls > account app cache db elasticbeanstalk empty games kerberos lib local lock log mail nis opt preserve run spool tmp www yp
4. I can't see to find the socket server code? Nor the logs for the socket server?

I am not sure where they would be located.

Answer 1

There are myriad methods to get code on to a server and to run it. Without any information about the code or the OS or anything else, assuming its a Linux based OS, if I'm looking for something and know what it is, I can usually find it by searching for a string that I know I will find inside at least one of the files on the server.

In this case, since its a socket.io, I'd search for socket.io:

grep -rnw '/' -e 'socket.io'

The result will show me all files, including the full path, that contain “socket.io”, and you should be able to determine where the code is pretty quickly.
