- login to jenkins box (ssh)
- switch user to jenkins "sudo su -s /bin/bash jenkins"
- go to jenkins home directory "cd ~"
- generate keys (you need separate pair per github private project as the projects are on the same domain)
- "ssh-keygen -t rsa -f ~/.ssh/id_rsa_<project>" (replace <project> with your project name)
- repeat this for every github project
- crate "config" file in .ssh dir - "vim ~/.ssh/config" with the following content:
# <project1>
Host github.com-<project1>
    HostName github.com
