Port Forward to 27017 Amazon DocumentDB Cluster loads forever

Question

I'm trying to configure a local port to forward connection to Amazon DocumentDB Cluster, but the command loads forever and don't get any error.

I'm following these instructions: https://docs.aws.amazon.com/documentdb/latest/developerguide/connect-from-outside-a-vpc.html

The command:

ssh -i "rsa.pem" -L 27017:docdb.cluster-XXXXX.us-east-1.docdb.amazonaws.com:27017 [email protected] -N

Expect: Port forward created.

Result: Command loading forever.

Answer 1

Most likely, the command has actually succeeded, and the tunnel is available for use. Try connecting to localhost:27017 to verify. (For example, open a separate terminal window and run telnet localhost 27017.)

(This is standard behavior for ssh -N; when it succeeds, it doesn't show any output and the command can look like it's just hanging.)
