Mongodb connection using r scripts
I'm trying to connect to mongodb having SSH credentials but facing problem to connect using mongolite package.
But at the same time to my local mongodb using credentials I'm able to connect. Any help on this?

What’s the error message you got?
By default, MongoDB is not allowed to remote access, you need to enable remote access by modifying mongod.conf file.
See: MongoDB – Allow remote access
Then to connect to MongoDB via an SSH tunnel, we need to setup the tunnel separately with an SSH client.
For example the mongolite manual contains this example:
con <- mongo("mtcars", url = "mongodb://readwrite:[email protected]:43942/jeroen_test")
Assume we want to tunnel through dev.opencpu.org which runs an SSH server on the standard port 22 with username jeroen. To initiate a tunnel from localhost:9999 to ds043942.mongolab.com:43942 via the ssh server dev.opencpu.org:22, open a terminal and run:
ssh -L 9999:ds043942.mongolab.com:43942 [email protected] -vN -p22
At last, we can connect to our ssh client which tunnel traffic to MongoDB server. In this example we run the ssh client on localhost port 9999:
con <- mongo("mtcars", url = "mongodb://readwrite:test@localhost:9999/jeroen_test")
con$insert(mtcars)
