I get this error when I try to configure the printers in KDE:

Unable to retrieve the printer list. Error message received from manager:

CUPS is installed and running.  I removed it and reinstalled to be
sure.  Also when I try to access the CUPS web interface on
http://localhost:631 it says:


Forbidden

You don't have permission to access the resource on this server.



Is CUPS listening on port 631 (use 'netstat -ant' to see)?

Is there a firewall blocking port 631 over the loopback interface?

When I type netstat -ant I get the following:

Active Internet connections (servers and established)

How do I check that the firewall is not blocking port 631?
