Hello, I'm new to Jenkins have some issue getting my jenkins master to connect to my slave via SSH.
My setup: 1. AWS EC2 instances ( 2 ) - m1.medium 2. Fedora-x86_64-20-20131211.1-sda - AMI 3. Jenkins ver. 1.555 4. Passwordless Authentication from master to slave When I input the credentials user: jenkins credentials: master ~/.ssh OR direct ssh key input It fails, with the log producing: [03/17/14 23:08:24] [SSH] Opening SSH connection to ec2-000.00.00.000-us-west-2.compute.amazonaws.com:22 <http://ec2-54-186-69-58.us-west-2.compute.amazonaws.com:22/>.
