Emilia SSH Access

In order to deploy OPQ to emilia.ics.hawaii.edu, you will generally need to configure ssh access to the opquser account. Here's how to do it.

Obtain opquser account credentials

Most services are deployed using the opquser account. You need to obtain the password for opquser on emilia in order to do this deployment.

ssh without password prompt

In order to use the scripts to transfer files, you need to set up SSH login without a password. You can follow these instructions.

To check to make sure you have set up your SSH keys correctly, bring up a new console and run the following command:

ssh -p 29862 opquser@emilia.ics.hawaii.edu

This should log you into emilia without prompting you for a password, with output like the following:

opquser@emilia:~$

ssh port forwarding

In certain situations, you may want to set up ssh port forwarding to create a port on your local machine that acts as if it was the MongoDB port on emilia. To do this, open a new shell, and execute the following command:

$ ssh -C -p 29862 -N -L 27017:localhost:27017 opquser@emilia.ics.hawaii.edu

The shell will appear to "hang", but that's OK: it just means port forwarding has started. Type control-C to terminate port forwarding.
