try it manually i.e ssh user-name@<node-ip> if it works I'll establish a connection automatically when you relaunch the node

Did u configure SSH on Node ie etc/ssh/sshd_config before connecting node in jenkins

Sumanth-lsvs commented 3 years ago

Hi Sumanth, As i have said in the class if you are using known hosts verification strategy, you should try connecting from jenkins master to jenkins node. This can be done after configuring /etc/ssh/sshd_config file after setting PasswordAuthentication to Yes (if you are using key based authentication) So do the following

  1. ssh in to jenkins master, become a root user switch to jenkins
  2. Now execute ssh jenkins@
  3. Now from jenkins ui configure the node.

Please watch & listen video carefully.

Once this works please close the issue
