Can't connect using mongo from vagrant instance.

[jondkelley]

I've validated I can telnet to the port I've forwarded from vagrant (localhost:27018) but the mongo client hangs trying to connect using mongo --host 127.0.0.1 --port 27018. This is also true using mongohub.

Vagrantfile port forward

config.vm.network "forwarded_port", guest: 27017, host: 27018

On parent host:

MongoDB shell version v3.6.5
connecting to: mongodb://127.0.0.1:27018/

Inside vagrant vm:

[root@localhost vagrant]# mongo --host 127.0.0.1 --port 27017
MongoDB shell version v3.6.5
connecting to: mongodb://127.0.0.1:27017/
MongoDB server version: 3.6.5
Welcome to the MongoDB shell.
For interactive help, type "help".

Here's my vars, I'm assuming mongodb_security_authorization: "disabled" is the relevant bits to allow unauthorized remote access.

The vars, run against Centos6 vm:

I am also facing same issue. I provisioned MongoDB using this ansible role on an AWS EC2 instance, I can ssh into the EC2 instance and see that MongoDB is up and running. But when I try to remotely connect from my localhost using mongo mongodb://[ip-address]:27017 I am getting the follow error:

MongoDB shell version v4.2.6
connecting to: mongodb://[ip-address]:27017/?compressors=disabled&gssapiServiceName=mongodb

Just figured out the issue.

With mongodb_net_bindip=127.0.0.1 mongodb can be connected from same host only. To enable connecting from remote(any) host set mongodb_net_bindip=0.0.0.0.
