sshAgent connection error through Pipeline with Private key

[sabharwal81]

Hello everyone,

I am stuck with one odd problem where i am trying to run remote command on linux server from my slave machine (windows server) as part of Pipeline script. As SSH connections are only supported using Private/Public Keys, i did follow steps mentioned in blog https://medium.com/@weblab_tech/how-to-publish-artifacts-in-jenkins-f021b17fde71 to generate keys to be later used for calls. Below are things i have done so far:

- Connected to slave server and created key using ssh-keygen.

- Created new credential using key/passphrase in Jenkins (id as server_ssh_key).

- Copied over the public key under /authorized_keys (id_rsa.pub) on the remote server.

- Connected from Slave server to the remote linux server through console to allow entry to "known host" file on the slave server.

- Updated Pipeline script to use below code to allow use of newly created credentials.

pipeline {

    options {

        timestamps()

    }

    agent {label 'att_server_slave'}

    stages {

        stage('Builds') {

steps {

script{

stage ('Starting build_rhel56_x64_1')  

{

  sshagent(credentials: ['server_ssh_key']) {

ssh 'ro...@192.168.2.111 ls'

}

}

}

}

        }

    }

}

when i am trying to run this pipeline script, i am getting below error:

00:13:26 [ssh-agent] Using credentials root

00:13:26 [ssh-agent] Looking for ssh-agent implementation...

00:13:27 [ssh-agent]   Exec ssh-agent (binary ssh-agent on a remote machine)

00:13:28       3 [main] ssh-add 2176 tty_list::allocate_tty: No tty allocated

Can someone please help in understanding what wrong i am doing? Or what specific check/step i am missing?

Thanks!
