Atheros AR5212/AR5213 wifi not working
by Marko Vojinovic 11 Oct '08

11 Oct '08

Hello everyone, I'm new to the CentOS list, so forgive me if this has been answered before (someone please point me to an efficient way of searching through the list archives). I have a wifi card from the subject line, and have the driver installed. Using NetworkManager under Gnome everything works perfectly. However, I prefer to use network service instead of NetworkManager since a) I use KDE and NetworkManager fails to work properly there b) this is a desktop machine, online 24/7 and I want wireless active even when I am not logged in. But when I use the network service, wifi0 fails after a delay, and /var/log/messages says there are no dhcp offers available. However, I am sure that there are several wireless networks available, with a strong signal. How to solve this? I would even accept using NM if it works as a daemon, ie even if I'm not logged in, and under KDE (which it doesn't atm). I believe the problem is essentially in the (in)ability to choose the appropriate network automatically --- in KDE NM doesn't have the taskbar applet which would let me choose the network, and the network service has no way of automatically making such a choice either... Please help! Btw, this is somewhat urgent, I am supposed to make it work by monday, Oct. 13. Oh, I almost forgot, CentOS 5.2, fully updated. Best, :-) Marko

Since I put my new Centos box on the net, it frequently tr1es to make ftp contact with IP address 64.90.181.77 . Why is this, and does anyone recognize this IP address? Is it spyware? Mike.

NEW is new string. Hmm, why not ditch find entirely, and just use grep? Something like: TFIL=/usr/tmp/dummy$$.txt grep -Ilr "$STR" * > $TFIL for fil in $( cat $TFIL); do sed -i "s/$STR/$NEW/g" $fil done Man grep says: "-I Process a binary file as if it did not contain matching data". Also -l gives you the filename and relative path. If $STR contains "/"s then you could use # instead. sed -i "s#$STR#$NEW#g" $fil I dont know how much the searched for string would change, but you could test if it contained "/" and then use sed with "#" instead. Also you might want to use "sed -ibak ..." instead since this will backup the unchanged file to filename.bak, should your substitution go awry. The letters after "i" specify the extension you want to use. Eric Sisolak

Fwd: P5GC SATA mode problem
by Eduardo Grosclaude 10 Oct '08

10 Oct '08

Hello, I'm top-posting my own thread with some homework I've done, can somebody help? In short, the problem is that kernel 2.6.18-53 (as per 5.1 installation) works OK while any kernel update makes booting impossible in Enhanced SATA mode. For newer kernels, only Compatible mode works, but at a very heavy cost in performance. The motherboard is ASUS P5GC-MX and the disk is ATA WDC WD3200AAJS-6. More detail in my own former message at the end. 1. I have tried pci=nommconf, noacpi, acpi=off. Any other hints? 2. I've opened up both initrd files (initrd-2.6.18-53.el5.img, which works in "SATA/enhanced" mode, and the newer initrd-2.6.18-92.1.13.el5.img, which only works in "compatible") and found practically no differences (USB modules are loaded in a different order and that's about it). 3. In the hope that I could build up a working kernel (albeit sacrificing ease of update) I tried to figure out some useful config. I've scanned both config-XXX files but I am unable to identify any reasonable suspects either, diff provided below. Should SCSI-SAS-ATA be different? 4. Just to play a while, attempted to make mrproper and got the following. Same for make clean. [root@localhost 2.6.18-92.1.13.el5-i686]# make mrproper scripts/Makefile.clean:17: /usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile: No such file or directory make[3]: *** No rule to make target `/usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile'. Stop. make[2]: *** [drivers/infiniband/hw/amso1100] Error 2 make[1]: *** [drivers/infiniband] Error 2 make: *** [_clean_drivers] Error 2 So it seems 5.2's kernel really doesn't like me. Now, my questions: 1. What is going on? What can I read to understand a bit more? 2. As for the disk drive behaviour, should I file a bug? I haven't found any related known bugs. Does it depend on whether ASUS P5GC-MX is or not on the HW CL? 3. Is it on the HW CL anyway? I assume it is, from what I read at http://www.linux-tested.com/results/asus_p5gc-mx.html 4. As for the kernel compile error, what is going on again? Any hints deeply appreciated!

My 5.2 DVD refused to see the hard disk. As the CD happened to have a bad MD5 sum, I assumed this was due to a bad burnt image. Backed off to 5.1. Installation of 5.1 to /dev/sda went OK, then I upgraded by yum to 5.2. But, at the next boot, the new kernel can't see the disk. Only when BIOS IDE Setup is "compatible" I can boot the new kernel. However, the disk shows up as /dev/hdc and performance is noticeably slow. If I choose any other mode, nash complains that any LVM groups can't be found and panics away. I/O in general is terrible. Copying a CDROM to a file with dd renders the machine nearly unusable. The kernel provided in 5.1 can work in the BIOS IDE Setup "enhanced/SATA" and performance is really good. Hdparm when under the current kernel says 3.51 MB/s buffered speed, whereas for the older kernel it claims some 111+ MB/s. I have updated the BIOS ROM to no avail. What am I missing? Is there anything I can do except keep trying kernel updates?

Hi Biz_User needs to switch to Sales_User, and I tried following in sudoers: Biz_User ALL=(Sales_User) ALL but I get following error when I run sudo su - Sales_User "Sorry, user Biz_User is not allowed to execute '/usr/bin/su - Sales_User' as root on Server_Name" I know that if I add root in allowed users list, I can switch to other user , but in that way user can switch to root as well. %Biz_Users ALL=(Sales_User,root) ALL any better idea ?

Xboard rpm for CentOS 4
by vandaman2002-rt＠yahoo.co.uk 10 Oct '08

10 Oct '08

Has anyone built an rpm for xboard for CentOS 4? I looked in the EPEL repo, KBS repo and rpmforge but none exist. The KBS repo has gnuchess in testing but what good is gnuchess without xboard? As usual the fedora SRPM for Fedora 6 and Fedora 9 cannot build on CentOS 4- they might build on CentOS 6 but i have no time machine :).

Installing a new VM on a xen box.
by James B. Byrne 10 Oct '08

10 Oct '08

HW = HPQ DC7700 DuoCore 1.8GHz, 4 x 2GB RAM, 1 x 1TB SATA (AHCI) OS = CentOS-5.2 ix_64 (xen) I am experimenting with Xen and with virtual machines in general for the first time. In consequence I have many questions. However, the one that I wish answered at the moment is simple: Given a DVD containing the CentOS-5.2_Final (i386) distribution mounted at /media/CentOS_5.2_Final on Dom0, what argument do I pass to the "Install Media URL" argument of the "Create a new virtual system" wizard" to install the 32 bit version of CentOS-5.2 onto a vm called test-1? I have tried things like: /media/CentOS_5.2_Final /media/CentOS_5.2_Final/images /media/CentOS_5.2_Final/images/diskboot.img etc. All attempts produce the same negative result. What URL is used to load the 32 bit OS from the dvd? I am a digest subscriber so the favour of a direct copy of any reply to the list is appreciated.

Video driver questions
by Robert Moskowitz 10 Oct '08

10 Oct '08

My OQO has a VIA chipset. From the hwconf: class: VIDEO bus: PCI detached: 0 desc: "VIA Technologies, Inc. CX700M2 UniChrome PRO II Graphics" vendorId: 1106 deviceId: 3157 subVendorId: 1106 subDeviceId: 3157 pciType: 1 pcidom: 0 pcibus: 1 pcidev: 0 pcifn: 0 When I install Centos, I default to the vesa driver, and it operates at the monitor's native 800x480. Of course I want more and to physically scroll the screen to see all of the content (the OQO has slide bars on it that do cause the current active window to scroll). When I change the monitor settings to Generic LCD 1024x768, I get that and 800x600 as an option. If I change the screen resolution to either 800x600 or 1024x768, and log out of X and log back in, my resolution is unchanged at 800x480. So I tried using the VIA driver that comes with Centos. It does not list the CX700, but, you know, give it a try. At first I get errors from X when logging in, finally I get changes to occur, but I am still at 800x480. Selecting 800x600 or 1024x768 mkaes no difference. Below is my /etc/X11/xorg.conf. Any ideas on what to try? # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" ModelName "LCD Panel 1024x768" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 31.5 - 48.0 VertRefresh 56.0 - 65.0 Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "vesa" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

More Samba Questions
by Joseph L. Casale 10 Oct '08

10 Oct '08

I have never setup a Samba server, and the recent thread here prompted to get on this I need to migrate two XP machines from using iSCSI to Samba. I thought the "+" preceding a username in the smb.conf file for a share definition told Samba to use the unix username? Unless I actually use swat to create and enable the user and take off the + it doesn't work. Any ideas what swat does when you create a user through that interface? Is there any way to simply force Samba to use locally created users in the share definition? Thanks! jlc
