CUPS and system-config-printer question
by Al Sparks 14 Jul '08

14 Jul '08

I was tasked with migrating a bunch of printer entries from one box to another. What I did is I got a list of printer names along with IP addresses and using the CUPS lpadmin -p printer-name -E -v lpd://IP_ADDR/lp I loaded them onto the new machine running RHEL 4.6. Printer tests show that it works fine. And if I use the CUPS web interface at http://localhost:631 Everything shows up. But if I launch the RH (and presumably CentOS works the same way) system-config-printer interface after adding the printers the CUPS way, nothing shows up in the RH interface. Probably not a big deal, but I have a colleague that will go nuts over this. He's attached to his interfaces, but there was no way I was going to manually enter those printers in that interface. Where do I look to make that interface "see" the CUPS-only printers? === Al

madwifi on Centos 5.2, kernel 2.6.18-92.1.6.el5
by Kurt Hansen 14 Jul '08

14 Jul '08

Hello, I just installed Centos 5.2 on my wife's IBM thinkpad T41 with Atheros wireless. It looks like I need to install madwifi to get the wireless to work. Our home wireless network uses WPA2 I found the EL5 rpms at atrpms, but there is no madwifi-kmdl rpms for kernel 2.6.18-92.1.6.el5. So, to get the wireless working on my home network, what's the shortest path from here? Install madwifi from source (was part the way there but discovered the rpms when I looked for the wpa_supplicant stuff)? Or, can I use one of the other madwifi-kmdl rpms? Or, go back to an earlier kernel? Thanks for your help! Take care, Kurt Hansen

14 Jul '08

I have been installed CENTOS 5.2 on several DELL servers and have following problems (even latest patches apply): 1. DELL 2650 can NOT boot under CENTOS 5.2 PAE mode 2. DELL R900 can NOT boot under CENTOS 5.2 PAE mode (inifinite boot loop) 3. DELL R900 with 128 GB RAM can only see 15 GB RAM under CENTOS 5.2 Xen mode Anyone know why? IS CENTOS 5.2 certify with DELL server? Does CENTOS 5.1 have similiar problem or NOT? Thanks. _______________________________________________________________________________________________________ 總會在某些時刻，突然想起舊情人？他現在過得還好嗎？ http://sev.search.yahoo.net

Cleaning up smp kernels
by Bowie Bailey 14 Jul '08

14 Jul '08

I have used the package-cleanup utility to remove old kernel packages, but I noticed that it only removes the 'kernel' and 'kernel-devel' packages. It does not touch 'kernel-smp', 'kernel-hugemem', etc. What is the recommended method of cleaning up these other kernel packages? Should I just 'yum remove' the ones I don't need? Some of my servers have a few piling up... # rpm -q kernel-smp kernel-smp-2.6.9-34.EL kernel-smp-2.6.9-34.0.1.EL kernel-smp-2.6.9-34.0.2.EL kernel-smp-2.6.9-42.0.2.EL kernel-smp-2.6.9-42.0.3.EL kernel-smp-2.6.9-55.0.2.EL kernel-smp-2.6.9-55.0.6.EL kernel-smp-2.6.9-67.0.1.EL kernel-smp-2.6.9-67.0.15.EL kernel-smp-2.6.9-67.0.20.EL -- Bowie

by Robert Moskowitz 14 Jul '08

14 Jul '08

Centos continues to fall behind in with the state of bluetooth development. Nothing new from 5.1 to 5.2. Has anyone got a more recent version working and have compile and rpm build instructions? Here are the rpms that I have: bluez-gnome-0.5-5.fc6.i386.rpm bluez-hcidump-1.32-1.i386.rpm bluez-libs-3.7-1.i386.rpm bluez-utils-3.7-2.el5.centos.i386.rpm bluez-utils-cups-3.7-2.el5.centos.i386.rpm gnome-bluetooth-0.7.0-10.2.el5.i386.rpm gnome-bluetooth-libs-0.7.0-10.2.el5.i386.rpm

Slow samba and Realtek card
by Emmanuel Borlet 14 Jul '08

14 Jul '08

Hello, We can see # lspci 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) I have used a custom kernel to start with centos 5.1 as an initial installation Our customer on this kernel has experienced slow pref on samba shares (50 seconds to open a file) So I have decided to updrade to centos 5.2 that have the right detection of this card inside (2.6.18-92.1.6.el5.centos.plus) [<http://wiki.centos.org/AdditionalResources/HardwareList/CentOS5/RealTek/r1 000?action=show&redirect=HardwareList%2FCentOS5%2FRealTek%2Fr1000>] # yum update # reboot The slow samba shares didn't disapear at all ! I have corrected the trouble by doing this : # cd /usr/src/ # curl -O ftp://218.210.127.132/cn/nic/r8101-1.007.00.tar.bz2 # tar jxvf r8101-1.007.00.tar.bz2 # cd r8101-1.007.00 # make clean modules # make install # depmod -a # insmod ./src/r8101.ko # reboot After the reboot we can see that the r8101 module has been activated # dmesg | egrep -i r[0-9]{4} Finaly the slow samba share was gone !

Excluding packages from mirrored repo
by Bowie Bailey 14 Jul '08

14 Jul '08

The RPMForge Tools list appears to be dead, so maybe someone here can help: I am mirroring the Centos4 updates repo using mrepo. My systems are all servers and have no need of OpenOffice, so I would like to be able to exclude the 4GB (i386 & x86_64) of OpenOffice rpms when I mirror the repo. I have looked at the mrepo docs and done some Google searches, but so far, I haven't come across a way to do this. I see there is an "rsync-options" setting in mrepo.conf. Would it be safe to add an "--exclude=" option here, or is there a better way? -- Bowie
