Dear All My resolv.conf looks as below search netcloudjobs.com nameserver 10.0.0.1 nameserver 8.8.8.8 nameserver 127.0.0.1 I do not have any error logs. I just did one modification in named.conf. *allow-query { localhost; 10.0.0.1/24; 10.0.0.254/24; }; * *Line I modified to * *allow-query { any; };* With this change, now I am able to ping to ns1.netcloudjobs.com . Problem is 50% resolved. Kindly guide me if allow-query any is right thing to do or not. Next, how do I make sure www.netcloudjobs.com should resolve to my IP. In my BIND server the, the command "dig www.netcloudjobs.com" gives below output.

lost connection during yum update
by Frank Cox 10 Mar '13

10 Mar '13

During today's big Centos 6 update I lost my connection to a machine during the "yum update" and when I logged back in and ran yum update again it told me to run yum-complete-transaction. When I ran yum-complete-transaction I got screen after screen of "x is a duplicate with x" where x consists of a huge list of packages. "package-cleanup --dupes" gives me a huge list of packages. I think that my next step here should be "package-cleanup --cleandupes" but when I do that it tells me that it will remove 800-plus mb of files. I suppose it's the the same list that I get with "package-cleanup --dupes". Do I want to do this or will that nuke the operating system? If not, what should I be doing? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER!

Wireless cannot ping gateway after 6.3 CR updates
by b.j. mcclure 10 Mar '13

10 Mar '13

I'm having a wireless connection issue with an HP laptop and a Zotac media server after the 6.4 package updates from CR repository. Nothing changed with wireless config as far as I can tell. Both have been working fine with previous releases of 6.x. Oddly, if a cat 5 cable is connected for a few seconds and then disconnected the wireless works fine and survives a 'service network restart' but does not survive a reboot. A laptop running Ubuntu 12.04 continues to connect normally. The boxes in question appear to connect to the router/accesspoint, are assigned correct static IPs, but cannot ping any box on the intranet including the router. No other boxes on the intranet can ping the hp or zotac, Once a network cable is inserted and removed all is well with that box. The zotac box uses the ath9k wireless driver, the HP uses b43. Same result using DHCP instead of static IP. Output of iwconfig appears normal on both errant boxes and does not change from non-working to working state. Google has not been much help. FWIW, here is output of iwconfig and ifconfig. ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:01:2E:BC:74:14 inet6 addr: fe80::201:2eff:febc:7414/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:1249 (1.2 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:89 errors:0 dropped:0 overruns:0 frame:0 TX packets:89 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:8807 (8.6 KiB) TX bytes:8807 (8.6 KiB) wlan0 Link encap:Ethernet HWaddr 74:F0:6D:8C:FE:CF inet addr:192.168.1.208 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::76f0:6dff:fe8c:fecf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:732 errors:0 dropped:0 overruns:0 frame:0 TX packets:79 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:107489 (104.9 KiB) TX bytes:9217 (9.0 KiB) [LSF@nra ~]$ iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"toadnet" Mode:Managed Frequency:2.437 GHz Access Point: 00:24:93:38:89:80 Bit Rate=54 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=70/70 Signal level=-28 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:29 Missed beacon:0 Any thoughts appreciated.

I had to stop using the fglrx video driver from ELRepo, which isn't supported with CentOS 6.4.

Re: [CentOS] Apache setup problems
by Bruce Whealton 09 Mar '13

Hello, Yes, I have installed php with yum. I used php* and just recently was told that there is nothing to install, it is all up to date. I did a yum search php first, and tried to install a bunch of php modules, all of which are already installed. I had done that a while back. I think I might have done that from the Centos desktop and now I'm working mainly from ssh. By not working, I mean that the index.php file does not get processed as php - yes, I checked that the file was renamed .php and that there is no .html file that could be run instead of the php file. So, I added to a test file named index.php, and in the body I have a simple <?php phpinfo(); ?> In the tutorials I found online, there is mention of the php configuration can be in the httpd.conf file or it can be called from that file. I have this line in the httpd.conf Include conf.d/*.conf Will that work? I am calling that from the file /etc/httpd/conf/httpd.conf so it seems like a relative path would be ../conf.d/*.conf, unless this is relative to this: ServerRoot "/etc/httpd" So, inside /etc/httpd/conf.d/php.conf I have # # PHP is an HTML-embedded scripting language which attempts to make it # easy for developers to write dynamically generated webpages. # <IfModule prefork.c> LoadModule php5_module modules/libphp5.so </IfModule> <IfModule worker.c> LoadModule php5_module modules/libphp5-zts.so </IfModule> # # Cause the PHP interpreter to handle files with a .php extension. # AddHandler php5-script .php AddType text/html .php # # Add index.php to the list of files that will be served as directory # indexes. # DirectoryIndex index.php # # Uncomment the following line to allow PHP to pretty-print .phps # files as PHP source code: # AddType application/x-httpd-php-source .phps That should be enough at least get the phpinfo(); command to run. At some point, I got a message about there not being a php.ini file anywhere. Also, none of the other various php modules are being called anywhere. Still, I'm perplexed that I cannot get anything to run in terms of php. I could try a simple echo command to test something even simpler. Thanks, It's great that there is such active response on this list... fast response times when seeking help. :-) Bruce _______________________________________________________ Bruce Whealton - Web Design/Development/Programming Future Wave Web Development: http://futurewaveonline.com Developing for the Desktop as well as for Mobile Devices - Smartphones/Tablets Call 919-636-5809 _______________________________________________________ -----Original Message----- From: Reindl Harald [mailto:h.reindl@thelounge.net] Sent: Saturday, March 09, 2013 2:17 PM To: CentOS mailing list Cc: Bruce Whealton Subject: Re: [CentOS] Apache setup problems Am 09.03.2013 20:02, schrieb Bruce Whealton: > The problem was with the SELinux.

Question around updates and drpms directory
by Stephen Harris 09 Mar '13

09 Mar '13

Looking at the nice new 6.4 tree (thanks!!!) I see there are already a few updates. eg Packages/firefox-17.0.3-1.el6.centos.i686.rpm Packages/firefox-17.0.3-1.el6.centos.x86_64.rpm So far, so normal. These occur because of timing. That's not a problem; it's expected. What confuses me, though, is the drpms directory where there are 33 firefox drpm files compared to the 2 Packages, including firefox-3 versions! The drpms directory is around 3.3G whereas the Packages directory is only 680M. Is the drpms directory carrying legacy files? Or is this to be expected? -- rgds Stephen

Cannot mount 3TB MyBook USB HD
by Miller,Jason [Burlington] 09 Mar '13

09 Mar '13

Hello, new Linux user here and I cannot mount a new (empty) WD MyBook Essentials 3TB USB external hard drive (Model WDBACW0030HBK-NESN). I'm only about 3 weeks into this linux thing and so please forgive me if any of my syntax is off My linux OS is CentOS 5.4 x86-64 running on a dedicated HP z400. The WD MyBook is to back up the large data files we are creating on the HP400 (it's used to run a DNA sequencer) I plugged the brand new MyBook into my XP system and cleaned out all the pre-installed WD files as soon as I got it, then plugged into my Linux system (2 completely separate machines). It failed to auto-mount with this error: Failed to read last sector (732558079): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sdc1': Invalid argument The device '/dev/sdc1' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? I've been searching in many forums and such but so far nothing I've tried has worked, including: Reformatting the HD (on the XP machine), NTFS format using 4096 byte allocation size (slow format, took hours) Reformatting the HD (on the XP machine), NTFS format using 512 byte allocation size (that the size used on the two ext3 internal drives; used "quick format" option this time) Adding a new directory: # mkdir /media/MyBook Then changing fstab to add line: /dev/sdc1 /media/MyBook ntfs-3g rw,umask=0000,defaults 0 0 Then: # mount /media/MyBook Which returned the same error each time I installed gparted, then opened the GUI program. It nicely displays the info on the two installed ext3 hard drives but that's all it shows Here's some info on other packages which were investigated, installed or updated in an attempt to mount this USB drive: ntfs-3g would not install, yum reported conflicts with fuse-ntfs-3g dkms-fuse is not installed dkms not installed fuse-ntfs-3g (updated to latest version) parted (updated to latest version) When I run # parted /dev/sdc Or # parted /dev/sdc1 I get this message: Warning: Device /dev/sdc has a logical sector size of 4096. Not all parts of GNU Parted support this at the moment, and the working code is HIGHLY EXPERIMENTAL. When I use "print" command in gparted I get Error: unable to open /dev/sdc (or /dev/sdc1) - unrecognized disk label I also tried fdisk # fdisk /dev/sdc And received this message: The number of cylinders for this disk is set to 45599. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other Oss (e.g., DOS FDISK, OS/2 FDISK) WARNING: The size of this disk is 3 TB DOS partition table format can not be used on drives for volumes larger than (2199023255040 bytes) for 512-byte sectors. Use parted(1) and GUID partition table format (GPT). Similar results when I used # fdisk /dev/sdc1 Except some number were different (ie number of cylinders report as 12180) What am I doing wrong? Is all this problem simply due to the size of the hard drive (3TB)? I also have a 1TB Seagate used to backup several other computers (all XP or Win7). Would I be better to use the Seagate on the linux and the WD on the windows systems?

UPS batteries, resolved
by m.roth＠5-cent.us 08 Mar '13

08 Mar '13

Well, whoever (or whoevers) recommended BatterySharks, thank you. I just got the order today, a bit sooner than I expected, and it was *exactly* what I'd asked for (HR batteries, all of them) and at their open market price, it was *low*, so it saved a non-defense sector of the US federal gov't a nice chunk o' change. Thanks. mark

recover lvm from pv
by Harold Pritchett 08 Mar '13

08 Mar '13

I have a vanilla CentOS 5.9 system. I have a pair of 2Tb sata drives with a RAID 1 array on them. This array contains an LVM physical volume. I have added these two drives to my system and now need to access the volume group on this physical volume. This volume group, vg0, contains 10 ext3 file systems and I need to get the data from them. What do I know: [root@mickey ~]# pvscan PV /dev/sda2 VG VolGroup00 lvm2 [465.66 GB / 0 free] PV /dev/sdb1 VG VolGroup00 lvm2 [465.75 GB / 0 free] PV /dev/md125 lvm2 [1.81 TB] Total: 3 [2.72 TB] / in use: 2 [931.41 GB] / in no VG: 1 [1.81 TB] [root@mickey ~]# The first two contain the running system. The third one, /dev/md125 is my lvm physical volume. [root@mickey ~]# pvdisplay --------- snip first two pvs ------- "/dev/md125" is a new physical volume of "1.81 TB" --- NEW Physical volume --- PV Name /dev/md125 VG Name PV Size 1.81 TB Allocatable NO PE Size (KByte) 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID UB2Zs1-2bau-frhn-TdQb-hXNi-H6c1-OgA6XZ [root@mickey ~]# I have spent the last 8 hours or so searching the web for the next command(s) I need to enter to mount this vg and the 10 filesystems in it. What other information do I need which may be available? Help! Thanks Harold
