i managed to resolve login problem but still facing issue while connecting my remote server using ssh key to jenkins.
i have shell script also where i am doing ssh connection from local to remote and normal execution is working fine without jenkins but when i schedule a build in jenkins it fails. seeking for the suggestions on this if step by step process can be suggested it will be great help. I am stuck in this problem from long time. i followed below steps to resolve it till now but didnt work: * Create an SSH key pair (public/private) *Ran the command “ssh-keygen -t rsa -C "Jenkins agent key" -f "jenkinsAgent_rsa" “* * Create an SSH credential in the Jenkins machine and put the private key there *Created the credentials and put jenkinsAgent_rsa into it.* * Create an SSH agent see https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/doc/CONFIGURE.md#configure-launch-agents-via-ssh <https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fjenkinsci%2Fssh-slaves-plugin%2Fblob%2Fmaster%2Fdoc%2FCONFIGURE.md%23configure-launch-agents-via-ssh&data=02%7C01%7Cssanders%40nycopportunity.nyc.gov%7Ca3b05396379a43b03ffc08d7aa5625a1%7C73d61799c28440228d4154cc4f1929ef%7C0%7C0%7C637165160528450979&sdata=ZwAy47%2Fxj2JYsbcVzz3gIvnFEvY%2BeFromHWpDgfOcoo%3D&reserved=0> – *This is creating a node which I didn’t do before – so I created the node and selected the credential with the private key. The verification strategy slect is non-verifying.* * Select the SSH credential created before as credentials * Chose the verification strategy that you want, see the documentation, if you have problems start with the "Non verifying Verification Strategy" you can change it later * Add the public key on ~/.ssh/authorized_keys *This was done* *I tried to relaunch the node and got the following:* SSH Connection failed with IOException: "Key exchange was not finished, connection is closed.", retrying in 15 seconds.
