samba on centos with printer drivers
by Dave 29 Mar '07

29 Mar '07

Hello, I'm trying to set up a CentOS 4.4 print server. I've attached a Usb Hp Deskjet 5150 printer to the box, and printed a test page. This worked fine, using cups. I then went to the samba howto, classical printer section, and followed the section for uploading pointprint drivers to the box. My first problem came when i told the error dialog no, then didn't see a new driver button in the resulting dialog either on the general tab or sharing tab. I next tried again, this time i said yes to the driver installation, went through, had the apw find the drivers, on my CD, and it uploaded them no errors or so i thought. The process completed without errors, the rom and the hard disk moved, yet checking the samba box in the print$ share nothing has been added and i have global permissions set for this operation. I am doing this as a member of the printeradmins group and in smb.conf i did set: use client driver = no default devmode = yes for i have had an issue with a previous deskjet uploading drivers, that one actually gave me an error, and adding default devmode fixed it. My samba version is 3.0.10 if that helps. Any suggestions welcome. Thanks. Dave.

4.92 Beta questions.
by David Mackintosh 29 Mar '07

29 Mar '07

Installing through PXE, interactively from an NFS source. The installer is in text mode even though I have 512MB of memory. Two questions. 1. When installing package sets, I do not see an "Everything" option the way there was in 4.x. Should there be? I also don't recall being asked if I wanted Server/Workstation/Custom groupings. 2. When partitioning the disk, if I accidentally select "Use free space and create a default layout", the installer naturally cannot do anything. However it's failure mode is to report, then prompt for a reboot. Shouldn't it go back to the previous menu? I actually opened the second one as a minor bug, but then thought maybe I should ask about it first. -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

DDR2 compile times (was Re: segfaults with 8 gig of ram)
by tblader 29 Mar '07

29 Mar '07

Hello All. Below are some compile times for 2.6.20 on an fx-62 running Centos64 with various 2 gig sticks of dual channel ram (See previous posts with subject of 'segfaults with 8gig of ram' for more details.) It seems dual channel will compile a kernel faster, but only gained around 30 seconds over 20 minutes. Below are the shortest/longest compile times of several compiles done over the weekend. Compile consisted of make menuconfig (save .config) time make dep clean bzImage modules 2 sticks dual channel @800mhz 10 samples ================================ real 791.46 user 664.10 sys 93.85 real 799.88 user 665.30 sys 93.87 4 sticks dual channel @400mhz 5 samples (before it hurled booting) ================================ real 876.19 user 712.98 sys 116.18 real 846.06 user 710.16 sys 115.42 3 sticks single channel @800mhz 6 samples ================================ real 815.74 user 673.73 sys 108.30 real 822.95 user 674.32 sys 108.62 -- Flambeau Inc.

If you rely solely on your tape software verification to tell you your tapes are 100%, there will come a day, you'll be in for a surprise. The only 100% sure fire way to determine if your tapes are good is to actually restore from them back to a drive, and open them with the applications that created those files. Only after that kind of testing, can you be sure your tapes are good. I've had many tapes verified from the days of Arcserve, through Brightstor, Arkeia, CTAR and BRU. All of these backup software systems ran, and verified flawlessly, then a disaster struck only to find out my verified tapes actually had problems with them. Now, the $64K is, how many files do you need to test?? :) Thanks!

segfaults with 8 gig of ram
by tblader 29 Mar '07

29 Mar '07

Hello All. I have five Centos 4.4 x86_64 (amd fx-62) boxes with 4 gig of Corsair dual channel ram running kernel 2.6.9-42.0.10.EL (smp). The sixth box is the same except for video card and ram. It is using 8gig of GSkill dual channel ram and has a very cheap ATI video card in it. This box will segfault on boot unless I use noapic acpi=off and nolapic. Even with these boot params, the box is not 100% stable. I have seen udev segfault right when booting and also when copying 15 meg files from /tmp to /usr will lock things up sometimes. Yum and Perl have gotten corrupted as well at different times. I have 5 fans in the box to vent heat and the BIOS reports the CPU running around 90 degrees Farenheit when rebooting. I have run memtest86 (from Knoppix 5.1) all night long on the 8 gig of ram and it comes up OK. In the past, we have found problematic Corsair ram this way. This 8 gig seems to be OK as far as memtest thinks. Today I will begin removing ram and testing to see what happens. Does anyone have some ideas what might be the problem? All the other five boxes with Corsair ram work fine. Thanks

Cups issue - keeps re-writing cupsd.conf and mime.types
by Justin Barth 29 Mar '07

29 Mar '07

Hi, My Centos 4.4 server at home is serving a Samsung SCX-4521F printer, which the *nix and Win clients connect to through ipp. Every so often (maybe once a month), the cupsd.conf and mime.types files are updated, which makes the printer unavailable to the clients. My fix so far has been to stop cups, overwrite the files with cupsd.conf.working and mime.types.working (these are backup files of the originial working files), then start cups. Now my question is - how simple would it be to make a bash script that will monitor if the files have been updated, then perform the above actions automatically? Or, how would I stop the files from being updated in the first place? I seem to remember coming across an article about cups-config-daemon, which can update the files occasionally - I have disabled cups-config-daemon in chkconfig, but somehow these 2 files are still being updated. Thanks for any advice! -justin
