Strongloop only binds to 127.0.0.1

Question

This question is on similar lines as this - Node.js connect only works on localhost - with the exception AFAIK that the only configuration available in Strongloop is the config.json.

I have tried using "0.0.0.0" in the config.json host value as shown below, but the netstat still shows it is bound only to 127.0.0.1

{
  "host": "0.0.0.0",
  "restApiRoot": "/api",
  "host": "0.0.0.0",
  "port": 3000,
  "remoting": {
    "context": {
      "enableHttpContext": false
    },
...
...

This is the log of netstat:

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN

This is my network config:

I am able to SSH into the vagrant box using 33.33.33.10. Replacing 0.0.0.0 with 33.33.33.10 also did not work. I tried removing the host attribute completely from the config, that didn't work either. UFW is disabled.

I have no other option to try, hence posting on SO :-)

Answer 1

Ok. I figured it out. The config is actually driven from Gruntfile.js. It's too confusing. There are too many places the host is defined.
