I'm not sure why you think CUPS is my baby, I have no affliation nor even heavy use of it. Heck, I've only used it reasonably often in two environments: One work environment on a linux desktop in a Windows only shop (much fun with samba, non/badly- documented copiers that pretend to be printers, and so on...) and a home environment where a mixed set of OSes talked to two printers (laser/inkjet) on different machines. Both were in the last couple of years. I was reporting on *my* experience and mentioned along the way what I thought might have been going on in your experience. Your browser going to odd places (assuming the link appeared to be valid) does not point the finger at CUPS (at least at first glance), but at what your browser was doing.

No, no. First off, its a quote from Douglas Adams' Hitchhiker's Guide To The Galaxy. Second, the idea is that after one finds how to do something, the next step is to ask why they do it, all existential-like, and finally the people eventually get tired of that and grow fat and stupid. Hence: > > And the web interfaces are generally a sign of civilization moving > > from the 'How can we eat?' stage past the 'Why do we eat?' and > > straight to the 'Where shall we have lunch?' stage... Implies that web interfaces are for the weak. This is silly, web interfaces are very froody, and so easy to use, they make an excellent alternative to command-line file editing, in many cases.

Well, I hadn't configured it yet! The machine with the printer has Redhat, Samba, and Cups installed and working fine. The Windows laptop prints; bin/lpr.cups on the Linux server prints. It seemed like it should be easy to make another Linux/Cups machine print, so I did "man lpr", which said a few things not to the point and SEE ALSO CUPS Software Users Manual, http://localhost:631/documentation.html So I did that, which gave me a page: cups> The CUPS web server provides a user-friendly "wizard" interface cups> for adding your printers.

I just tried it again, to refresh my memory what went wrong. It came up with a login box. I told it my /etc/passwd name and password (Is that what it wants? Why would it need it, I have been logged on all day? Maybe it wants some kind of printer specific name?) It just shows the login box again. I think I got past that point last time by telling it my root password, but I don't feel like trying that again right now. It was no help in setting up the printer, it just showed some forms to fill in with inscrutable labels, and occasionally locked up or hijacked my browser off to random web sites. I remembered that I had given it my password, and I had no idea why it was communicating with anything outside my local network. Paranoia strikes deep, so I stopped. > Your web browser had its auto-magical lookup functionality turned > on and went looking for what you specified when it couldn't connect > to the address you specified.

memtest hangs

by Gregory Avedissian

I'm testing some DDR ram (one pc2100 and one pc2700) in a dell 4500s (1.8GHz Intel) and memtest hangs on the second test - Address Test, Own Address, No Cache. I've tested the sticks together and separately, and the same thing happens. The test just stops after a minute or two, with no error messages and loss of keyboard control. Tested one stick in a different computer, and it tests fine. It's a brand new memory chip. The Dell seems to run slower than I'd expect for a 1.8GHz with 384MB RAM. I especially noticed it when I was installing software from source packages - it went a lot slower than on my 1.2GHz Athlon with 500MB of pc133. Other than that, it seems to run ok. Here are my questions: Is it obviously the cpu? Is there any linux software that will test the cpu similar to what memtest does with memory? Any suggestions for diagnosing this problem? Thanks, Greg

You remind me of Perlis's comment on Algol60: Not perfect, but a big improvement over its successors. I don't even know what LPRng is, I suppose it's the New-Gnu version of the ancient bin/lpr program, from back in the days when programs were more prized for working than for having a Web interface. My printer is attached to a dual boot machine that now runs Linux only, with a Samba server so that Diane can print via the network from her laptop. It worked pretty much the first time, the main problem being getting the Windows laptop to notice it. I can print from the printer/Linux machine, but when I tried to use the much-touted CUPS web-based set-up to connect to the printer from another Linux machine, it went totaly wonky. Certain buttons sent the browser in an apparent infinite loop. (By Turing, you can never be sure, but I waited long with no action) Sometimes it would take me to some crazy random place in the Internet, to pictures of buildings that had the same name as my server machine, as though some mad programmer had rewritten bin/hostname to search Google for its name.

Re: [Wlug] printers

LPRng is not that bad for a print server. In the ECE dept at WPI, we use LPRng beause CUPS IMHO is still rather buggy. We've tried switching over to CUPS on many occasions however have always ran into a bug that prevents us from performing the switch over. We've also used CUPS on our other servers to connet to the printer server running LPRng and have run into some troubles with that, which we have not using LPRng.

Don, I would recommend not using LPRng. It is too old. I understand that CUPS seems difficult, but once you understand it, it is the next best thing. In my office, I have setup my kickstart to install 300+ printers on all of my Redhat Linux V3 Workstation machines (100+). You can configure it via console, applet, or even web. Fedora and Redhat has gone that route and I believe that others have too. It is much better than LPRng can every be.

printers

by Don Peterson

Hello there, I am new here, and new to Linux. My company is in the middle of a platform migration for our Oracle ERP system. We are moving away from Solaris towards a Intel/Linux solution. I've got a quick question about printers. Is there a printers.conf file in Red Hat like there is in Solaris (I couldn't find one). Here's my issue: I have 5 servers in a 9i RAC array and I don't want to set up my 50 printers on each server. Can anyone suggest a way to "copy" the printers I set up on one server to the other 4? Any help would be greatly appreciated. Don Peterson MCP/DCSE Network/Telecommunications Administrator Sterilite Corporation 30 Scales Lane Townsend, Ma 01469

Maybe at the time we do a Binary Gentoo install and then go into detail about how to emerge and build the apps at a later date. That might actually get me to use Gentoo again. If I can have a fully configured system in a short amount of time, I can setup cron jobs to build optimized versions at night. > > > Also, can the gentoo build work via distcc?

I could get into this type of meeting. In fact, watching the time it takes to do a Gentoo install vs say Knoppix is prat of the fun. I can also provide some Yellow Dog Linux 3.0.1 Cds for anyone interested in trying to run Linux on a PPC. I'd like to see how Fedora Core install is progressing these days. I have SUSE 9.1 Pro sitting here that I'd also like to see run, if anyone has some guts and a machine. :) I can even see about bringing along a PC that can use a new install. Also, can the gentoo build work via distcc? I'm wondering if we can leech some cycles opff idle laptops to speed the Gentoo build up. Ahh here it is: http://www.gentoo.org/doc/en/distcc.xml#bootstrapping The distcc thought might take some coordinatino though. Just some thoughts/ramblings. Brian

Re: [Wlug] another vote for a future meeting topic

how far into the gentoo install can you get? Is the last step the long process? I can volunteer a fast machine if we could get most of the way thru at the meeting and I can just kill it at the end. Or is every step along the way very time consuming? We could have several pc's setup installing all at once so people could see a knoppix install or a SUse install or a gentoo all at once --- Ryan Caron <rcaron(a)WPI.EDU> wrote: > No, the install isn't the easiest thing to someone > not familar with it, > but the Gentoo documentation is quite good.

Date: Tue, 31 Aug 2004 15:45:04 -0400 (EDT) From: "Peter Gutowski" <peter(a)linuxchamps.com> I have a 960 Photo printer. Excellent print quality and drivers were available on a RHL9 install. A friend has a 2200 running on a Mac: it appears to be identical to the 960, just wider to accomodate larger sheet size. That said, beware of consumeables $$$!!!!! I've spent far more in ink and paper since January than I paid for the printer! (And I really don't print a lot.) For Linux use, I would recommend the 2200 over the 960 hands down, if you can use Gimp-Print 5.0 (which is currently in beta). I have both of them. I consider myself qualified on this subject, as the Gimp-Print project lead.

Running approx $9.95@ mailorder. A full box of 50 sheets 8.5x11 glossy paper (~$23 from Amazon) seems to use up a full ink set, maybe a little more depending on coverage. You'd think that roll paper might be cheaper, but I haven't found that to be the case. (Maybe supply and demand at work here.) I'm on my 3rd box of paper since January. Also, generic printing in less that "High Quality Photo" mode seems to much less ink. -Peter
