Starting from Mongo version 3.2 you can do it by using mongodump/mongorestore:

mongodump  --host  --db  --archive | mongorestore --host  --archive

Additional info could be found at:

To make remote mongo reachable you can create ssh tunnel to it:

creates a tunnel to the remote mongodb server and tunnels it through port 27117 to the local client

ssh -fN -L 27117:localhost:27017  

In this case the command to run on the local machine you want to restore to could be:

mongodump  --port 27117 --db  --archive | mongorestore --archive
