How do you administer CUPS remotely using the web interface?

I found this way to be simpler.

# cupsctl --remote-admin --remote-any --share-printers

It will update the /etc/cups/cupsd.conf file and restart cups for you, saving a backup of the previous configuration in the same folder.

It's the similar to the method presented in the official CUPS guide to printer sharing. I found the options --remote-admin in man cupsctl.

The way I normally achieve this is to tunnel over ssh via an arbitrary port:

ssh [email protected] -T -L 3631:localhost:631

Secure, and allows remote access. Won't solve all problems but useful for irregular access.

Mission achomplished! This page helped me out a lot.

All I had to do was add "Allow all" to to the access to the server and the admin pages so that my configuration now looked like:

# Restrict access to the admin pages...
<Location /admin>
  Order allow,deny
  Allow all
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Default
  Require user @SYSTEM
  Order allow,deny
</Location>

Now I just need to figure out to only allow those on my local network to access the admin pages and the configuration files :) (though it's probably not a big deal since I don't have port forwarding for 631 set up on the router?).

EDIT: To only allow a certain computer I could have done something like

<Location /admin>
      Order allow,deny
      Allow from 10.10.10.5
</Location>

Or for the whole 10.10.10 subnet,

<Location /admin>
      Order allow, deny
      Allow from 10.10.10.*
</Location>
