What is sunproxyadmin service?

Question

I was trying to run a front end project locally after pulling it down from git. After which I got the following error:

vents.js:183
  throw er; // Unhandled 'error' event
  ^

Error: listen EADDRINUSE 127.0.0.1:8081
    at Object._errnoException (util.js:1022:11)

npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I was like, "Hold up, i'm not running anything!!". or was I? After running

sudo lsof -i :8081

I saw:

COMMAND PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
cma     265 root   16u  IPv6 0x2756c3c2bce3e369      0t0  TCP *:sunproxyadmin (LISTEN)

I saw that webpack-dev-server was trying to start on the same port as sunproxyadmin

...
  devServer: {
    port: 8081,
    hot: true,
  },
 ...

Ok, so what is sunproxyadmin and who is cma (get off my lawn!!!) (btw I know how to kill it)

PS: Some one with more stack overflow points who agrees please create tags for sunproxyadmin, EADDRINUSE and cma

After digging around I see that cma is an agent of Mcaffe which is using sunproxyadmin.

I figured I could just find out how to change the port it uses but then I don't have access to change the port that it uses on my machine because it is set by our IT department and the process itself is started by the root user:

The wakeup port is a global setting, so you can't just change it on certain agents: it has to be all of them...

To change the port, simply change it in the Configuration / Server Settings page, and the agents will pick up the new port the next time they contact the server.

Most searches on this topic lead to issues with react for some reason which is probably why I found the solution for killing it here:

sudo lsof -n -i4TCP:8081 # get the process' PID
sudo launchctl list | grep 5693 # find the launchd endpoint
sudo launchctl remove com.mcafee.agent.macmn 

So in the end killing it was my only recourse other than changing the port webpack dev server starts up with.
