Oh, and if you REALLY think you want root access, JumpBox has a "How To" about it here: http://www.jumpbox.com/archives/140_how-to-access-a-jumpbox-as-root.html.

Several ways you could do this:

1) Probably the most secure method is to SCP the module to the "admin" user folder
(ssh your-module.tar.gz admin@machin-name-or-op:~/)
and then SSH into the box and move the file manually to where it needs to go (e.g. /var/data/drupal/sites/[all|default|your-site.com]/modules/) and untar it.

2) Less secure (also quick and dirty) would be to CHMOD accordingly the directory you want to upload to and SCP directly to where it needs to go, SSH in and untar the file, or just SCP the already untarred folder.

3) Install an FTP Server (proftpd comes to mind) and use FTP. If you're not familiar with configuring proftpd, you might spin your wheels here. This might be a good suggestion for the guys at JumpBox to have pre-configured on the next version of this machine.

Save yourself some time and gather up all the modules you plan to use, and tar them up in one file so you only have to do this one time.

Good luck!

Pardon me, but I just downloaded the Drupal version of Jumpbox yesterday and I cannot figure out how to add modules to the system.

I've SSH into the jumpbox and the drupal directory is owned by root, whereas I am only admin, so I cannot write to the sites/all directory.

In order to add modules, I'll need to be able to write to the sites directory.
