Username and Password Authentication
- Overview
- Linux machines allow us to login using ssh protocol and configurations of ssh are present in
/etc/ssh/sshd_config- The field PasswordAuthentication should be yes
sudo nano /etc/ssh/sshd_config
# Change PasswordAuthentication to yes
sudo systemctl restart sshd
- Create a user called as jenkins
- Lets make jenkins administrator
sudo visudo
* Lets ask not to prompt for password for jenkins user
* Do the same stuff for node 2
