If you have SSH access to the administrative shell, you can run GitHub Enterprise Server's command line utilities. SSH access is also useful for troubleshooting, running backups, and configuring replication. Administrative SSH access is managed separately from Git SSH access and is accessible only via port 122.
To enable administrative SSH access, you must add your SSH public key to your instance's list of authorized keys.
Tip: Changes to authorized SSH keys take effect immediately.
- From an administrative account on GitHub Enterprise Server, click in the upper-right corner of any page.
- In the left sidebar, click Management Console.
- Under "SSH access", paste your key into the text box, then click Add key.
- Under the left sidebar, click Save settings.
- Wait for the configuration run to complete.
After you've added your SSH key to the list, connect to the instance over SSH as the
admin user on port 122.
$ ssh -p 122 firstname.lastname@example.org Last login: Sun Nov 9 07:53:29 2014 from 169.254.1.1 admin@github-example-com:~$ █
If you encounter the
Permission denied (publickey) error when you try to connect to your GitHub Enterprise Server instance via SSH, confirm that you are connecting over port 122. You may need to explicitly specify which private SSH key to use.
To specify a private SSH key using the command line, run
ssh with the
ssh -i /path/to/ghe_private_key -p 122 admin@hostname
You can also specify a private SSH key using the SSH configuration file (
Host hostname IdentityFile /path/to/ghe_private_key User admin Port 122
In an emergency situation, for example if SSH is unavailable, you can access the administrative shell locally. Sign in as the
admin user and use the password established during initial setup of GitHub Enterprise Server.
Administrative shell access is permitted for troubleshooting and performing documented operations procedures only. Modifying system and application files, running programs, or installing unsupported software packages may void your support contract. Please contact GitHub Enterprise Support or GitHub Premium Support if you have a question about the activities allowed by your support contract.
