CUPS LAN printing problem (from Vista)
by Keith Roberts 19 Jul '11

19 Jul '11

I have my main machine running Centos 5.6, and it has a HP Deskjet 810c printer physically attached to it. CUPSD broadcasts in on my LAN as the default printer. I can print to the default HP printer over the LAN, from a laptop running Centos 5.6. However, I do have problems trying to print to this same printer over the LAN, from a laptop running M$ Vista. Has anyone been able to print from a machine running M$ Windoze Vista to their CUPS LAN printer running on Centos 5.x please. All I need to know is yes, this works, or no it's not possible. The other alternavie and easiest way is for me to buy a USB printer cable, and just connect directly from the Vista laptop to the HP printer using that.

EL6, xinetd, and permissions. What am I missing?
by Benjamin Smith 19 Jul '11

19 Jul '11

Staging for a rollout of EL 6, and ran into a very strange permissions issue with xinetd that defies all (my) logic. It's a script called "spfiled" that we use for messaging between our server cluster servers. I'm trying to get it to run with "least permissions necessary". Because it reads/writes files in conjunction with a web-based service, it runs as user "apache". Here's my xinet.d/spfiled.conf: (this is in dev, each developer has his own number) #################### spfiled.conf ################## service spfiled461 { socket_type = stream wait = no user = apache group = apache server = /path/to/filed.php protocol = tcp disable = no bind = 192.168.3.2 port = 12461 banner_fail = /path/to/banner_fail.txt cps = 10000 0 max_load = 10.0 } #################### spfiled.conf ################## Here's the permissions of the script: # ls -laFd /path/to/filed.php -rwxr-xr-- 1 bens apache 18042 Jan 7 2011 filed.php When I restart xinetd, I see in system log: #################### /var/log/messages ################## Jul 18 16:32:25 bender xinetd[17830]: Server /path/to/filed.php is not executable [file=/etc/xinetd.d/spfiled461] [line=11] Jul 18 16:32:25 bender xinetd[17830]: Error parsing attribute server - DISABLING SERVICE [file=/etc/xinetd.d/spfiled461] [line=11] I've turned off SELinux completely. # setenforce 0; Strangely, setting permissions to o+x and it starts up fine, but I don't want to leave permissions that open.

Wireless Interface Does Not Connect Automatically At StartUp
by Manish Kathuria 19 Jul '11

19 Jul '11

I have recently installed CentOS 6 on a system with a Realtek 8180L wireless card. The wireless card is detected properly and uses the rtl8180 driver. But it connects to our wireless network only after logging to the Desktop Environment (GNOME) and using the Network Manager Applet. In order to make the wireless card connect to the network automatically at system start up, I edited the Connection using the Network Manager Applet and checked "Connect Automatically" and "Available to all users" options. However, while booting the system, the following error message is displayed when the wireless network interface is brought up. Device does not seem to be present, delaying initialization But as soon as a user logs on to the Desktop, he can connect to the network using the NM Applet. I have also toggled between using DHCP and Static IP Address for the the wireless card but it makes no difference. The SSID is not being broadcast and the Wireless Access Point / Router uses WPA-PSK. TIA, -- Manish Kathuria

cent0s-6 and virtualbox
by Michel Donais 19 Jul '11

19 Jul '11

I want to get a look at Cents-6 The computer is a portable Thinkpad T-42 The base OS is Windows XP Professionnal I tried to use both Microsoft Virtual PC and Oracle Virtual Box with the same result I boot from the CD (wich have been burned from an ISO downloaded from a Centos -6 repo). The version is CentOS-6.0-i386-bin-DVD.iso With each virtual machine I get this result at the beginning of the installation: "This kernel requires the following features not present on the cpu pae" "Unable to boot - please use a kernel appropriate for your CPU" I undeerstand that perhaps the computer processor is too old. But is there a patch to overpass this problem? --- Michel Donais

Thanks, Jerry

system-config-kickstart error Centos 6
by Jerry Geis 18 Jul '11

18 Jul '11

I have noticed that if you have a %include in your kickstart file and the include file does not exist (It's created in my %pre section) - - I could not even bring up the kickstart editor. I get an error about the file could not be opened. No reason why and then the editor just exists. I had to keep chopping down my file till I found the offending line. Hope this helps someone else...

Spamhaus with Zimbra Mail on CentOS
by Alex Marz 18 Jul '11

18 Jul '11

I realize this is slightly off topic, but I've noticed recently that I've been unable to preform RBL lookups using the the zen and sbl spamhaus RBL lists. Currently using Zimbra Collaboration Suite using CentOS 5 I'm seeing logs showing the following output. [root@phantom ~]# cat /var/log/zimbra.log | grep spamhaus Jul 18 13:07:12 phantom postfix/smtpd[27001]: warning: 107.178.203.192.zen.spamhaus.org: RBL lookup error: Host or domain name not found.

Name service error for name=202.200.26.72.zen.spamhaus.org type=A: Host not found, try again After doing some reading I've tried a number of DNS servers ( thinking the issue may have been DNS poisoning ) all of which appear to be unable to preform dig lookups the spamhaus hosts. Is anyone else seeing similar results?

CentOS 6 x86_64 DVD doesn't boot
by Kanwar Ranbir Sandhu 18 Jul '11

18 Jul '11

Hi Everyone, I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to a rewritable DVD. When I tried to boot my new home server off it, it didn't, and then this was printed to the screen: ETCDisolinux: Found something at drive = EF No DEFAULT or UI configuration directive found! boot: The same disc works fine in my 4 year old HP laptop, and when installing CentOS 6 as a KVM. I've found one post from a Fedora 14 user that was having the exact same problem, but no one replied to him. Other articles, posts etc. around the net reference something different for the "EF" part. Does anyone know what's going on? I've never seen this problem before.

Kernel panic - not syncing: Attempted to kill init! after installation of Driver Diskette for enabling Onboard RAID Controller Chipset
by Kaushal Shriyan 18 Jul '11

18 Jul '11

Hi, I have HP DL 180 G6 2U Rack Server with HP Smart Array Controller Card B110i Onboard SATA Controller Chipset. This server has 4 * 500 GB SATA HDD have configured RAID 1+0 and it shows Single Logical Drive of 940 GB Hard Disk in the RAID BIOS. Have created driver diskette using dd command to enable this controller card to the CentOS 5.6 x86_64 arch and it shows HP LOGICAL VOLUME of size 940 GB by the Anaconda installer to load CentOS 5.6 on these server. Below are the steps to enable driver diskette from HP (http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?sw…) gunzip hpahcisr-1.2.6-7.rhel5.x86_64.dd.gz dd if=hpahcisr-1.2.6-7.rhel5.x86_64.dd of=/dev/sdb (USB Flash Drive) CentOS 5.6 Installation Procedure :- Boot up the System using DVD containing CentOS 5.6 and type linux dd blacklist=ahci and then it asks for load driver diskette and then point it to the USB Flash Drive which contains the SATA Controller driver image. The driver gets loaded during the installation and after OS Installation is complete and then reboot it fails and says "Error 21: Selected disk does not exist" and when i edit grub grub> root (hd0,0) and press b to boot it works fine and later I get the below message on the Console with Kernel Panic. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! Am i missing anything? Please suggest/guide. Regards, Kaushal
