I am trying to add one more node using the following Steps: (Note: Adding other 3 nodes(or slaves) completed successfully)
1.Manage Jenkins -> Configure System -> SSH Remote Hosts
2.Under SSH Remote Hosts -> Host Name: 192.168.242.30 -> Port: 22 -> Username: auto_ci
Launch Method: Launch Slave Agents on Unix machines via SSH
Jenkins Return Message: Could not connect to server
Illustration:
IP Address of the master: 192.168.240.33 IP Address of the slave node: 192.168.242.30 (runs as a Clearcase terminal)
Normal ssh login using Putty or any SSH Tool, from 192.168.240.33 system to 192.168.242.30 works fine.
Node Log on Jenkins shows:
USER=auto_ci
_=bash

This is a Unix slave
