Verify your System
Ignore these points if just:out and just:connect are running on another machine – or in case you are working on a rundown using an offline channel. Contact your system administrator if necessary.
Make sure that the channel is ready by verifying the following points.
just:out is running.
just:connect is running and there is a green light besides the channel you want to use.
Connect
just:control is ready on your machine.
You know the channel you would like to connect to and the corresponding user/password combination to connect to that channel.
