Unable to create New Node on Jenkins

[kishorejaan1]

--> I have made my user as adiminstrator from " visudo " and passwordauthentication = Yes.
--> Even I tried to send Keys also from Jenkins to Node.. Even though am getting same error..
--> Installed mvn, jdk8, git also.

Could you please let me know did I miss anything...

hi, try changing the HOST KEY VERIFICATION STRATEGEY : select none and try again, hopefully it would work

I am also facing the same issue, have you found any solution for this??

[rajeshande430]

guy, try changing the host key verification stratagey to non verifying verification strategy and use aws machine public ip, i am sure you will be able to get through the connection from master to node.

this worked for me

Bro try manually trusted key verification strategy it's working for me.

[rajeshande430]

The Perfect solution for this is for the option " known hosts file verification strategy " is below:

in My case JENKINS_HOME = /home/jenkins/

copy the know_hosts file in Master ~/.ssh/known_hosts to <JENKINS_HOME>/.ssh

]# cd ~
]# cd .ssh
]# cp known_host <JENKINS_HOME>/.ssh
]# cd /home/jenkins/.ssh/
jenkins@ip-172-31-42-138:$ cd .ssh/
jenkins@ip-172-31-42-138:/.ssh$ ls -ltrc
