Jenkins SSHD connection

Question

Having trouble finding information on using Jenkins SSHD, there's a RSA key (publickey?) supplied by the X-Instance-Identity header when browsing the top page.

Trouble is, it's not clear how to use this.

I've tried the obvious, and added it to ~/.ssh/id_rsa_jenkins and then attempted to connect, after first setting the SSHD port in Jenkins config to 8822

ssh -i ~/.ssh/id_rsa_jenkins -p 8822 jenkins_server

(and alternatively)

ssh -i ~/.ssh/id_rsa_jenkins -p 8822 user@jenkins_server

However, with both of these connection attempts, I'm challenged for a passphrase, which I don't have (attempting to use the user login fails.)

Does anyone have any ideas?

Answer 1

Managed to figure this out, from the Jenkins top page (when logged in)

> People > User > Configure

Then find SSH Public keys, paste the rsa/dsa public key in here and save, and you can log in.
