Shell Programming and Scripting

Code:

netstat -an | grep 27017
tcp        0      0 127.0.0.1:27012         0.0.0.0:*               LISTEN
unix  2      [ ACC ]     STREAM     LISTENING     6534678  /tmp/mongodb-27012.sock

Yes that is why you cannot telnet to that port from the IP address you provided.

Your DB is bound to 127.0.0.1 as mentioned

Neo helped resolve the issue. Changing MongoDB port to 0.0.0.0 and restarting works fine.

Thanks for the update.

I do not advise binding your DB to 0.0.0.0 or your server's IP address because this can open up your DB to outside attackers.

Normally, web admins bind the DB to the localhost so only processes which originate on the localhost can assess the DB, for security reasons.

In other words, for security reasons, you should design your system so you do not need to telnet or otherwise remotely connect to your DB.
