Answer 1

Looks like you're using keyfile authentication, so you'll get this error from Jenkins if you haven't set the permissions correctly on your .ssh folder and/or ~/.ssh/authorized_keys file.

• the .ssh folder should have drwx------ permissions (read/write/execute owner only)
• the authorized_keys file should have -rw------- permissions (read/write owner only)

To fix it:

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Answer 2

Don't do any ssh-keygen. Just enter the pem key details under key field, Add SSH server details: Name, Hostname and Username as ec2-user. Click test connection and it works.

Because your linux login need password, the answer is :

 1. Passphrase: your passphrase

Answer 4

Sometimes the SSH connection would fail, if the destination server doesnt have enough disk space to perform PUT operation

{ERROR: Exception when publishing, exception message [Failure]}

Make sure to verify the destination server has enough disk space.

In case of Linux, you can use 'df -kh /directoryname' to check the disk space
