Is there a simple way to disable ssh in Photon 3 OVA?
I'm running a couple DNS slaves using NSD, and have no need for SSH to be enabled, especially when the OVA enables root login by default (I know I can disable that.)
Seems that disabling SSH would be a great security measure, as most systems have it disabled by default.
I guess I could add the stop command to a new service, but would like to do it properly.
I would prefer not to do it through iptables as there are some times it is handy to use SSH instead of the remote console access in VMware, but then I could enable for that session.
systemctl stop sshd
systemctl disable sshd

You can do as Graham said to disable it temporary but on the next reboot sshd will be up again.
To disable it on boot you whould use the command chkconfig, I think you can try chkconfig sshd off.
To list your service on boot you can use the command chkconfig--list.
