Ubuntu – Environment variables over non-interactive SSH connection

sshUbuntu

I'm using a product called vlad which is making non-interactive ssh connections to my Ubuntu server but the problem is that it can't see any of the environment variables.

I've been googling like crazy but can't find a solution. I've tried adding the variables to an .ssh/environment file for the user on my server and also changing the settings in /etc/ssh/sshd_config but no joy.

Can anyone help?

Cheers,

Chris

Check you /etc/ssh/ssh_config (on client) and look at SendEnv option. In my case, I have SendEnv LANG LC_*.

There is some interresting informtions in the man ssh_config

Kyle is definitely right about one thing - your shell is not being spawned properly. But that exit status makes me think that it's a problem with the shell itself, not the machine being unable to fork a process.

If I had to guess, I'd say your shell has been disabled - possibly by setting it to /bin/false or similar.

Assuming you have UsePAM yes in /etc/ssh/sshd_config, and assuming you want these environment variables set for every user, you can have pam set environment variables for you. If you have the environment variables defined in /etc/gitenv you could add this line to /etc/pam.d/sshd

auth required pam_env.so envfile=/etc/gitenv

Or by inpsecting this file, you might find that there is already a pam_env.so being used, and already a file you can add stuff to. Just be careful, and make sure you have thoroughly tested your changes before ending your ssh session, as when you are messing with pam, you can completely break your ability to login to your server, if you are not careful.
