Change network services access from command line

Hi everyone

Using Server 5 on El Capitan. I was adjusting some settings in the Access pane of Server. I was restricting Remote Administration (and screen sharing?) to one specific machine - but made a typo. The end result was restricting access to 127.0.0.1 and the incorrect address. So I can no long remote administer the machine with the Server app, not with ARD , and nor can I vnc into it.

I do, however, have ssh access.

Is there a way to adjust the IP associated with the remote administration service from the command line?

Thanks

-Jeff.
