Enabling Telnet or RSH access to the cluster

Telnet and RSH are disabled in the predefined management firewall policy (mgmt). To enable the cluster to accept Telnet or RSH requests, you must create a new management firewall policy that has Telnet or RSH enabled and then associate the new policy with the cluster management LIF.

About this task

Data ONTAP prevents you from changing predefined firewall policies, but you can create a new policy by cloning the predefined mgmt management firewall policy and then enabling Telnet or RSH under the new policy. However, Telnet and RSH are not secure protocols, so you should consider using SSH to access the cluster. SSH provides a secure remote shell and interactive network session.

Steps

  1. Use the system services firewall policy clone command to create a new management firewall policy based on the mgmt management firewall policy.
  2. Use the system services firewall policy create command to enable Telnet or RSH in the new management firewall policy.
  3. Use the network interface modify command to associate the new policy with the cluster management LIF.
