2. if the connectivity is fine we can SSH from the CP to HV.

We can use the following command for this:

sudo onapp ssh root@<HV IP>

If the server mentioned has no resolvers or is unable to access the outside world, it could be taking too long to allow the SSH connection.

3. Now, we need to SSH into the HV

4. And edit /etc/ssh/sshd_config 

Here we have to set “UseDNS no”

5. Finally, we need to restart sshd.

/etc/init.d/sshd restart

If it is a cloudboot server, the commands to change the file and restart sshd have to be added to the custom config.
