I will have a look at the settings and send back the files with any mods required.

Please comment the changes as then I can learn for next time.

Very much appreciated!!

I have looked at the files. The client.conf is OK. I have added a number of comments to the cupsd.conf. There were a few settings wrong which I have fixed. Also there was a few lines right at the end of the file which were definitely crap, which I have commented out.

There are two main errors as far as I can tell, firstly the ServerName setting looked incorrect, replaced it with its IP address. Secondly you had missed the BrowseAddress setting.

Just replace the /etc/cups/cupsd.conf with the one attached. You don't need to replace the client.conf in the other machine as it has the correct settings.

See how you go and get back to me if it still doesn't work.

For your information the security section in cupsd.conf has a certain syntax which starts with and ends with </Location>

For example <Location /> Order Allow,Deny Allow From 127.0.0.1 Allow From 127.0.0.2 Allow From @LOCAL </Location>

A large number of the security options are commented out and are only required if you want to further limit access to certain functions. Thank you again Graham for looking at and editing the necessary files. I have reverted back to the list in case it helps others.

I know, from Windows days, that the server must be booted first, ten the clients. I did this specifically making sure the printer initialized. I figured now, with the correct conf files, it would a simple matter of pressing print on the Mozilla GUI on the client and the page would automagically eject from the printer connected to the server. Alas I was wrong. :( I 'checked' the client settings via the Yast printer configuration but all was in place. I noticed that the test failed when I tested connectivity to the server in Yast.

You could try running "cupsd" from the command line, check with ps that it's running and if not, there should be something in /var/log/cups/error_log. Until the server is up and running, there will be no ipp network broadcasts. When I ran rccups on the server the following was displayed: Server: # rccups start Starting cups #cupsd: Child exited with status 98! ( I had to Ctrl-C to get back to the #)

Client: #rccups start Shutdown cups Restarting cups # I had the same results when I ran #'rccups restart' [snip]

...

Also " lppasswd -a root" or you will get access errors from "http://localhost:631". Thanks for that. It partially solved getting into the CUPS web interface, on the client anyway.

Server: When I did a #'lppasswd -a root' on the server, the command completed OK, but when I tried to access the CUPS docs by entering in 'http://localhost:631' on the address bar of Firefox, the server quickly came back and told me that 'Connection refused whilst attempting to connect to localhost:631'. Even if I try and enter 'localhost:631' in a konqueror window, Firefox still strarts up and gives me the message. Client: Command completed no problem and I was able to get into the web admin interface using Mozilla Navigator, but after clicking on 'printers' and 'admin' the interface went belly up and displayed nothing but a white screen. The browser back button didn't help either.

...

YaST should also have setup stuff in /etc/cups/, printers.conf and printcap. That I'll look into later. At the moment I need to find out what cups error 98 is as I cannot find it via the SuSE help access to the CUPS manual. I also need to get cups started at boot. but for the life of me I do not know where to get it to start at boot. When I went into 'Network services' under Yast there was no cups service listed there and asides from that I didn't know all the details to add it in.

For testing CUPS you should be using the commands that come with CUPS. Have a look at the manual that comes with cups before you end up messing up the config files again. http://localhost:631 Firstly what is the output of lpstat -t on both your server and client. Kprinter has the problem of not recognising a new IP address if it has an IP address already set. Check on the client machine in ~/.kde/share/config/kdeprinterrc and make sure it has the correct IP address in it as shown below [CUPS] Host=<IP-Address> (should be the same as /etc/cups/client.conf). Don't worry if there is no setting for your server as long as it doesn't have an invalid IP address. -- Regards, Graham Smith

I'll have a look at http://localhost:631 but will stay out of the files as much as possible, as, in theory, they work.

Don't worry if there is no setting for your server as long as it doesn't have an invalid IP address.

I assume those should be deleted?

The lpstat command prints the status of the CUPS server. man lpstat will give you all the options. From the above it appears that cups is not running properly. I suggest you run as root rccups restart and then see if lpstat -t reports the status of Cups. You should get something similar to the following --------------------------------- lpstat -t scheduler is running system default destination: CLP550N device for CLP550N: lpd://10.212.64.20/lp device for CLP550N/duplex: lpd://10.212.64.20/lp device for CLP550N/env: lpd://10.212.64.20/lp CLP550N accepting requests since Jan 01 00:00 CLP550N/duplex accepting requests since Jan 01 00:00 CLP550N/env accepting requests since Jan 01 00:00 printer CLP550N is idle. enabled since Jan 01 00:00 Data file sent successfully printer CLP550N/duplex is idle. enabled since Jan 01 00:00 Data file sent successfully printer CLP550N/env is idle. enabled since Jan 01 00:00 Data file sent successfully --------------------------------------- If you cannot get a similar output, then cups is not starting. Have a look at the error messages in /var/log/cups/error_log It should give you a reason why it is failing. If you can't work out what is wrong send me the last part of the log. <SNIPPED>

I just checked the '..' are actually tab stops that your editor displays as a '.' You will notice them everywhere I have added comments. The other thing I just thought of, if you have been using the printing manager in KDE it can corrupt the /etc/cups/cupsd.conf file. If that is the case have a look at the end of the file and check to see there are no extraneous lines been added to the file. -- Regards, Graham Smith

The lpstat command prints the status of the CUPS server. man lpstat will give you all the options.

From the above it appears that cups is not running properly. I suggest you run as root rccups restart and then see if lpstat -t reports the status of Cups. You should get something similar to the following

--------------------------------- lpstat -t scheduler is running system default destination: CLP550N device for CLP550N: lpd://10.212.64.20/lp device for CLP550N/duplex: lpd://10.212.64.20/lp device for CLP550N/env: lpd://10.212.64.20/lp CLP550N accepting requests since Jan 01 00:00 CLP550N/duplex accepting requests since Jan 01 00:00 CLP550N/env accepting requests since Jan 01 00:00 printer CLP550N is idle. enabled since Jan 01 00:00 Data file sent successfully printer CLP550N/duplex is idle. enabled since Jan 01 00:00 Data file sent successfully printer CLP550N/env is idle. enabled since Jan 01 00:00 Data file sent successfully Lucky you :) All I get is as before :( Server: hylton@Umalusi:~> lpstat -t lpstat:Unable to connect to server: connection refused

The server I not worry about but I am wondering about your servername entry in the client.conf file as it seems to have 2 full stops after the IP ie 192.168.0.1 .. before your comment. I assume those should be deleted?

I just checked the '..' are actually tab stops that your editor displays as a '.' You will notice them everywhere I have added comments. Also saw that when I opened and pressed the TAB key in Kate :)

I asked you to post your /etc/hosts file because you have something wrong with your network configuration. That is what all the error messages in the cups log are saying and Cups will not start until you sort out your network configuration problems. You can send them to me directly if you like and I'll sort it out for you. I hate it when these things drag on forever. -- Regards, Graham Smith

NO amount of clicking on the close option or even looking for kprinter under a terminal screen could get the KPrinter dialogs to disappear. I also tried the printer manager from the printer icon on the task bar with the same result. It actually took 2 reboots to rid myself of the Kprinter dialogs.

So, now what needs tweaking? Especially since I get a 100msec ping reply from the server when I ping 192.168.0.1 on the client side.

I assume that because I am getting a reply back on the ping that the machines are 'talking' to one another. Where should I check error messages after I have tried to print?

For testing CUPS you should be using the commands that come with CUPS. Have a look at the manual that comes with cups before you end up messing up the config files again. http://localhost:631 I tried by opening up Mozilla MAil, making sure I was offline, opened a Navigator session, went online and entered te above text.

You should be able to use konqueror to open the above URL or try http://127.0.0.1:631 (If the latter one works I suspect that your /etc/hosts is not configured properly). If that doesn't work you can down load the manual from http://www.cups.org/documentation.php The one you need is the Software Users Manual -- Regards, Graham Smith

You should be able to use konqueror to open the above URL or try http://127.0.0.1:631 (If the latter one works I suspect that your /etc/hosts is not configured properly).

If that doesn't work you can down load the manual from http://www.cups.org/documentation.php The one you need is the Software Users Manual Hi Graham Smith,

I have installed CUPS as part of the standard 9.3 SUSE install, but when I go to localhost:631 and make a selection it askes that I logon. I tried root and my root p/w but that was not accepted. What is one to do at that point? PeterB

Read http://portal.suse.com/sdb/en/2004/03/jsmeix_print-einrichten-91.html, especially part "Changes in CUPS" about lppasswd. -Kastus

You should not be asked for a password when you connect to localhost:631 but if you try to do any printer administration you will be asked for one. Unless you have used lppasswd to assign a password you won't get any further. man lppasswd will give you full details for the command but I generally use lppasswd -a root to assign a password to root for this. -- Regards, Graham Smith
