Solano CI Server Fingerprints¶
Solano CI’s server SSH public key fingerprints are:
Configuring SSH Access to Solano CI¶
See SSH Key Management for details on how to manage your SSH keys in Solano CI.
Configuring SSH Inside the Test Environment¶
You can add new entries to the default list of SSH known hosts by
checking in a copy of your known hosts file as
If you get a
Host key verification failed error message, you should
add the target host name to
config/ssh_known_hosts. Any entries in
this file will be appended to the known hosts file in the worker.
You can also add known hosts entries to
solano.yml. For instance:
--- known_hosts: - github.com,126.96.36.199 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAq2A7hR...
Once your worker has booted, it will append the contents to the generated SSH known hosts file that is automatically installed.
You can extend the default SSH configuration installed in
$HOME/.ssh/ssh_config by checking in a file called
Debugging SSH Key Problems¶
Debugging authentication problems can be difficult since SSH is itself not simple and multiple configuration files, the SSH agent, and multiple keys can all be involved. If you have used the Solano CLI, it will have set up a remote pointing to git.solanolabs.com. You can find the URL of your Solano CI git cache by using the following sequence of commands in the shell:
git remote -v | grep solano | grep push
This command will print out the push URL for your Solano CI git cache. Take the user and hostname part (uNNN@git.solanolabs.com) and ssh to it:
ssh -vv uNNN@git.solanolabs.com
You should see a lot of output, and an error at the end. In the middle,
you’ll see the list of keys that ssh tried to send. If you don’t see
the key that you have authorized in Solano CI, it means that ssh (which
git uses) didn’t know to send that key. One way to configure SSH to use
a specific key is to add the following to
Github and SSH¶
GitHub has a document on how to generate and authorize SSH keys here; you need only
authorize the key printed by
solano account as Solano CI has already
generated a key for you. This key is also available in the web UI under
the “SSH Worker Identity” menu item under “Organizations > Organization
If you see a key already in use error from Github, follow the instructions from Github.
