I am trying to make a client with mongo c++ drivers to connect to the database. I successfully tested the client for the localhost.The code I used for that is below.
Now I want to have the database and clients on different machines for example client on IP 10.1.2.56 and the mongodb on IP 10.1.2.57
I changes should I make in the code to achieve that. I tried to change the line
c.connect("localhost"); //"192.168.58.1");
To
c.connect("10.1.2.57"); //"192.168.58.1");
But that does not work
The error says "caught can't connect to server 10.1.2.57:27017 " I tried to ping the IP 10.1.2.57 and it give me the response also .

I found the Answer of the above question
Earlier the mongod was running on the defined port and path on the Mongodb server side
So I stoped the Mongodb by following command
$ sudo stop mongodb
and once again started the server with the default defined path by the following command
$ sudo mongod --dbpath /data/db --port 27017
and then tried the above code in c++ and this time it connected to the remote server.
