Then terminate sshd running on TCP Port 19999 as follows:\r\npkill -f /usr/sbin/sshd -p 19999\r\n4.Additional steps can be performed on Supervisor to remove the keys associated with tunneluser account:\r\nrm -f /opt/phoenix/deployment/id_rsa.pub.tunneluser\r\nrm -f /home/tunneluser/.ssh/authorized_keys\r\nrm -f /opt/phoenix/id_rsa.tunneluser ~admin/.ssh/id_rsa\r\nCustomers are also advised to disable \"tunneluser\" SSH access on port 22 by following the steps bwlow:\r\n1. SSH to the Supervisor node as the root user.\r\n2. Add/edit the following line in sshd_config file: \r\necho DenyUsers tunneluser >> /etc/ssh/sshd_config\r\n3. service sshd restart"
