Hi Folks

I am having some fun and games with CUPS. I have several machines running Slack 10.0, but not all of them have this problem.
I have installed a number of printers with their respective ppds using the web-interface and when I attempt to configure the page size etc. with the "Configure Printer" button, I get the infamous "server-error-internal-error" message. After setting LogLevel to "debug" I saw this message in /var/log/cups/error_log:
D [11/Aug/2004:13:52:08 +0200] SendError() 9 code=403 (Forbidden)
The "code=403" is kinda like an http error, but I don't know what CUPS is trying to tell me. Could someone narrow this down a bit for me?
The fact that I only get this on some of the machines seems to indicate something that I am doing during the installation, I just wish I knew what. (BTW, I have not installed lprng at all, so there's no clash happening with symlinks etc.)

I know what is wrong.

You have a differering name in your /etc/cups/cupsd.conf and /etc/hosts. What I mean is that, in your /etc/cups/cupsd.conf ServerName is different from your machine name. Change it so that it is the same and restart cups.

You may have to add in /etc/cups/cupsd.conf some lines which look like :
(for a network 192.168.0.0/24)

<Location /printers/YourPrinterName>
Order Deny,Allow
Deny From All
Allow From 192.168.0.0/24
</Location>

Nope, I have checked the ServerName thing and it's not that .

Cedrik:
I probably should've mentioned that I have edited cupsd.conf so that I can configure the printers from other machines, so I the IP addies in <Location> and <Admin>.

And did you check the ServerName in /etc/cups/client.conf of your machines ?

After reading Cedrik's suggestion about the ServerName in client.conf I decided to comment it out in cupsd.conf so that it would read /etc/hosts, and this appears to have fixed the problem. I am rather bemused because I have configured a CUPS server like this in 9.1 without these issues.
Thanks for the help carboncopy and Cedrik .

This is quite old but since I found it very helpful I am replying so maybe it will help someonne else.
I do not understand all the code below that you suggested adding but it seems to have solved the problem. I was in doube if I should add the line "allow from 192.168.0.0/24" or if it should be my printer address. I added the line as you put it (I copied and pasted the entire code) and it worked. Thanks.
