--Boundary-00=_phdCAPeMtkcAZmY Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Content-Disposition: inline Indeed, we have a big problem getting CUPS to work with FreeBSD 5.1. The root of the problem is in the fact that it does not install properly! (I think this is completely the responsibility of the folks at FreeBSDMall, who clearly didn't test the system they sell in the box!) I suppose I should have (and still should) written all the steps I had to do to get it working. So, here's a list of what I remember having to do, and why: 1) The software expects to be installed in /usr/sbin, but FreeBSD's version puts it in /usr/local/sbin. If that isn't in your path, none of the command line stuff will work, and this includes even starting cupsd or using lpadmin. 2) CUPS expects its config files and other stuff to be in /etc/cups, but FreeBSD puts that stuff in /usr/local/etc/cups. This means that even if you make the path correct for finding the program, it won't find any of its control or configuration files and will die almost instantly if you start it from a shell. 3)CUPS expects its spool file directory to be in /var/spool/cups, but FreeBSD5.1 puts similar stuff below /var/spool/output, so you might want to continue this philosophy by creating /var/spool/output/cups. Neither of these dirs exist or are created when you install cups. You can decide which one of them you want to use and create it... but don't forget to give it and its sub parts (I'll talk about them shortly) the proper owner:group (either root:daemon or daemon:daemon, your choice). You'll need a sub-dir called tmp with the same owner attribs below where ever you create the cups dir. 4) Cups requires (even if you aren't using certificates) a sub-dir to the /usr/local/etc/cups dir called certs, and the ownership requirements are the same as in 3, above. If the dir isn't there, cupsd won't get far before dying somewhat ungracefully, and it isn't created by default... you have to do it. 5) The cupsd.conf that comes with the installation isn't aware of any of the above misplacements or that any of this might be missing. Thus, it has to be edited. I've attached the version I am successfully using now to this message. You'll almost certainly have to change it to fit where you decide to put things, but it's a good start. Be aware of the error reporting level parts of this file, as they can help you a lot when you've finally got to the point where you can start the program. You'll want to tone it down later, after things are up and running smoothly, but having it fairly verbose can really help a lot at first. 6) The printers.conf, mime.types, .convs and other .conf files all go in the /usr/local/etc/cups dir. You'll also probably have to create a ppd directory under /usr/local/etc/cups, as well, as I don't believe it got created automagically. 7) If you're using any of the more recent printers (one of mine is an HP deskjet 960c) that isn't in the hpijs add-on to gs, you'll have to go get them and put them into the ppd dir mentioned in step 6. If you get this far and are having trouble figuring out what needs to go where to do this part, let me know and I'll send another message with the specifics of what I did to get it to work. 8) Finally, cups expects its control script file to be in /etc/rc.d, and that it will be named cups.sh If you look hard enough through the documentation, you can find that there is supposed to be a file there called cups.sh.sample that you can edit and rename or copy for your installation to make it work. This is a really idiotic chicken and egg situation, as you can normally only see the documentation to find this out if you can run the cups daemon and get to the web pages at port 631, but you really should start and control the daemon with the shell script. It's almost funny, in a really sadistic way. In any event, you can either search around and find the sample file, edit it and move it to /usr/local/etc/rc.d, or use the one attached here and put it in that dir. Don't forget where you put it... you may want to either edit it or use it later! 9) With all this done, I believe you will be able to do "/usr/local/etc/rc.d/cups.sh start" and the beast should come alive. You can then point your favorite browser at http://localhost:631 and you should see the nice cups web control interface. If you don't, have a look at /var/log/messages, or where ever you told cups to put its error messages in the cupsd.conf file, and you will probably get something meaningful in the way of an error message that will lead you to fix something. (This is especially true if I left anything out here, but I hope I didn't.) Then you can try again. I hope this helps you (and anyone else struggling with this problem). I got wonderful advice (and patience) from Peter Ulrich Kruppa in Germany. Without his pointers, I'd still be fighting with this thing! Certainly, if you have further questions about the cups installation on FreeBSD5.1, let me know and I'll do my best to assist. -Lyman --Boundary-00=_phdCAPeMtkcAZmY Content-Type: text/plain; charset="iso-8859-1"; name="cupsd.conf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="cupsd.conf" # # "$Id: cupsd.conf.in,v 1.10 2002/12/17 22:08:08 mike Exp $" # # Sample configuration file for the Common UNIX Printing System (CUPS) # scheduler. # # Copyright 1997-2003 by Easy Software Products, all rights reserved. # # These coded instructions, statements, and computer programs are the # property of Easy Software Products and are protected by Federal # copyright law.
