Passwordless SSHD daemon for OSX

Need to run commands through SSH in user's UI session ? Then this is for you.

How to install ?

• Install customssd

brew tap xfreebird/utils
brew install customsshd

• Generate SSH public/private key

ssh-keygen -t rsa -f sshd_rsa_key

Now you should have two files:

sshd_rsa_key - private SSH key to be stored in Jenkins

sshd_rsa_key.pub - public SSH key that will be used by customsshd

• Install the customsshd launchd service

customsshd install sshd_rsa_key.pub

• Configure OSX to autologing your user at startup, this will start the daemon too.
• Configure Jenkins Slave with SSH port 50111, and the generated private SSH key sshd_rsa_key

Why ?

Since Xcode 6 running iOS unit tests through standard SSH connection on the build machine failed the tests.

Timed out waiting 120 seconds for simulator to boot, current state is 1. If you believe this error represents a bug, please attach the log 

The solution is to run those tests in user's UI session.

How it works ?

• When machine starts the configured user, and autologins it, the customssd is started by launchd in user UI session.
• customssd injects the provided public ssh key to $HOME/.ssh/authorized_keys. In this way Jenkins or any other client can connect to the machine with the private SSH key and run commands in user's UI session.
• customssd keeps the public key and other files in $HOME/.customsshd

Usage

• Get version:

customsshd -v

• Install/update the launchd service:

customsshd install sshd_rsa_key.pub

• Stop the launchd service:

launchctl unload ~/Library/LaunchAgents/com.customsshd.plist

• Start the launchd service:

launchctl load ~/Library/LaunchAgents/com.customsshd.plist

Logs

All standard output is stored in /tmp/customsshd.log. Error logs in /tmp/customsshd_err.log.
