Which other hosts? Other hosts in the same subnet as dns1 and dns2? If that is the problem, maybe you should try changing "mask 255.255.255.0" to "mask 255.255.255.255". The "mask 255.255.255.0" means all the class C subnet.

mount: /dev/sdb1 already mounted or /blah busy
by Al Sparks 23 Apr '08

23 Apr '08

How do I go about troubeshooting this? I'm using RHEL 4 update 6. mount: /dev/sdb1 already mounted or /blah busy It's actually an iSCSI LUN (NetApp filer). I successfully configured (ext3) and mounted it, but when I rebooted, the /dev/sdb1 device/partition is seen by the kernel and it shows up with "fdisk -l". Nevertheless I get that error. I've tried "umount" and am informed that /blah isn't mounted. I've tried "lsof" and don't find a process that's attached to /blah. I also tried "fsck -t ext3 /dev/sdb1" which worked (so it detects the ext3 file system). Any other tools to check out? === Al

22 Apr '08

Excuse my ignorance (I just got crap on the #centos IRC channel for this question), but is there a (easy!) way to have and IRC and/or Jabber server relay a login to a Microsoft Active Directory server for authentication? If there's a better question to ask this question, please point me in that direction, and I'll be happy to do so Thanks

Can't get .htaccess to work
by Pam Astor 22 Apr '08

22 Apr '08

Hi, I'm trying to password protect one of my web accessable directories and I can't get .htaccess to work in a Centos 5.1 box Here's what I did I created an .htaccess file with the contents: AuthName "Restricted Area" AuthType Basic AuthUserFile /home/mysite/.htpasswd AuthGroupFile /dev/null require valid-user and I uploaded it to the dir I want to protect. Then I created my password outside of my web dir with the command: htpasswd -c .htpasswd pam then followed password prompts, created my password. So then I go to the site, and am not seeing any password required box, I can see site without a login. So then I figured it's not turned on in apache, and went to httpd.conf and changed AllowOverride None to AllowOverride AuthConfig When I reload, apache will not reload. What am I doing wrong? _________________________________________________________________ Pack up or back up–use SkyDrive to transfer files or keep extra copies.

Kickstart network settings problem

I would like one of my kickstart scripts to prompt for disk and networking only. Commenting out the disk and network settings makes the installer prompt for disk settings but not for network settings, they default to DHCP. Any idea's how to fix this? Thanks Dean

fdisk partition table plus sign

What does the plus sign after the blocks value exactly mean in the fdisk output? Some research reveals that it indicates that not all the blocks are included in the fdisk value. But what does this exactly mean? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

dd backup of lv
by Joseph L. Casale 22 Apr '08

22 Apr '08

I have a series of unmounted lv's that are used in xen vm's of various flavors in a lab environment. I made a script that I use to backup all of them prior to doing anything I may need to undo and all I execute is: dd if=/dev/vgname/lvname of=/dir/name.img Are there any additional parameters I should use? I haven't tried to restore this into an lv, but I did swap the 'phy' specification for 'file' and started a vm using the backed up image and it was fine. Thanks! jlc

iptables details
by Fajar Priyanto 22 Apr '08

22 Apr '08

Hi all, I'm a bit confused reading the RHEL System-Administrator-Guide regarding this: (1) iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to 10.1.2.253:80 (2) iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination 10.1.2.253:80 The first is for port forwarding, the second is said to be used for DMZ. But I tried both and the result is the same. Is there any difference between the two?

last resort before hard reboot
by Joshua Frankamp 22 Apr '08

22 Apr '08

Is there a resource for CentOS for things to do before a hard reboot? My situation is apparently an out of memory condition where I am seeing fatal 'oops' output all over the place, Ctrl-Alt-F3 (for example) new console login attempts will accept credentials and then never get to a login prompt. Remoting in is just as useless. I cannot therefore use any of the standard restart commands, since I cannot enter commands. By default in CentOs (and on my machine) Alt- SysRq is disabled. Do I have any other options before hard resetting the box? Thanks, - Joshua

Odd behaviour with modules; looking for some theories
by Miskell, Craig 22 Apr '08

22 Apr '08

Hi all, Recently, after doing some maintenance on one of my servers (Centos 5), I rebooted. On reboot, it didn't find the SAN disks at all, and after some poking around in maintenance mode, I discovered that it couldn't find the Qlogic module. It turns out that /lib/modules/<kernel-version>/modules.alias, modules.dep and such were all empty or just had their header comment lines. moddep -a fixed things up quickly enough once I figured out what was going on. However, I'm kinda stumped as to how these files got nuked in the first place. It wasn't files being deleted completely, it's like they were regenerated incorrectly. Checking backups showed these files were last changed (to their short form) on Feb 11; yum.log doesn't show any sign of updates on that date, so presumably it wasn't something like a kernel installation running amok. Does anyone have any theories as to what happened? Random logical guesses is fine ;-) Thanks, Craig Miskell, Technical Support, AgResearch Invermay 03 489-9279 "Usenet is like a herd of performing elephants with diarrhea -- massive, difficult to redirect, awe-inspiring, entertaining, and a source of mind- boggling amounts of excrement when you least expect it." -- Gene "spaf" Spafford (1992) ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.

rejecting I/O to offline device (PERC woes)
by Curtis H. Wilbar Jr. 22 Apr '08

22 Apr '08

Haven't gotten any tips on a solution to the problem below. It happened again this weekend. My next test steps (order not determined): 1. Downgrade to CentOS 4 2. Swap out PERC controller with a spare I have never had a problem with the PERC4/DC controllers on our other machines (RHEL3/4, CentOS 4). Although, I've no other machine that has 5 300G Fujitsu SCSI drives either. Any suggestions on the below, or which order on the above to try ? Thanks, -- Curt ------------------------------- I have a 6650 with a PERC4/DC running CentOS5. After 1 to 3 weeks of operation (running VMWare Server) it 'dies' (raid array gets taken offline) and you get rejecting I/O to offline device. When this system was setup late last year, the 6650 was given all the latest firmware along with the PERC4/DC. using linttylog, the last entries from when the system must have 'checked out' last night, I see the data attached below. Some time back I thought I had cured this problem by adding noapic to the kernel boot parameters in boot.conf. It had gone away for a long time... but is now back. according to lintty, it reports controller firmware is: T0: Firmware version 352D build on Mar 19 2007 at 17:43:23 T0: MegaRAID Series 518 firmware version 352D using strings tty.log | grep 'MedErr on pd' | cut -c17- | sort | uniq -c | sort -n I see: 163 REC:log MedErr on pd[1] #retries=0 165 REC:log MedErr on pd[4] #retries=0 168 REC:log MedErr on pd[2] #retries=0 If I am to believe this, Patrol read is finding media errors on physical drives 1, 2, and 4 ! ? These drives are not even a year old, and to have an almost even distribution of errors across 3 drives seems far fetched (unless patrol read is reading past the end of drive ?, but then it would be doing that with all 5 drives). Is the PERC busted ? driver issue ? I'm running CentOS 5 with kernel 2.6.18-53.1.13.el5PAE from dmesg, megaraid related driver versions: megaraid cmm: 2.20.2.7 (Release Date: Sun Jul 16 00:01:03 EST 2006) megaraid: 2.20.5.1 (Release Date: Thu Nov 16 15:32:35 EST 2006) Anyone seen this behavior before ? Anyone have a solution ? We have several Dells in a hosting environment with PERC4/DC running RHEL3, RHEL4.X, and CentOS4.X. We have not had this issue on any of them (though they do not have 5 300G Fujitsu SCSI drives in a RAID 5 config either (as this one does)). Hoping someone can shed some light on this... so far I keep coming up short on finding a solution.

Good news for virtual EL-4.x boxes
by Stephen John Smoogen 21 Apr '08

21 Apr '08

Currently, if you are running CentOS-4.x on a Vmware box you end up with time skew problems. The main fix has been using a set of recompiled kernel that has a HZ that is more fitting with what Vmware expects (eg 100 hz). The 4.7 kernels look like they will not need this: http://jons-thoughts.blogspot.com/2008/04/rhel-and-vmware-time-skew-problem… Well, I've gotten quite the number of questions over the last few days about time skew problems in RHEL4 and VMWare, so figured that I would write this. In RHEL4.7, there will be a kernel feature that allows you to pass 'divider=' on the command line in grub. The number must be a divisor of 1000, and the most common value is 10 (yielding an effective timer interrupt rate of 100Hz). I'm expecting the 4.7 beta to become available Real Soon Now(TM), though I have no information as to when that will occur. In the meantime, this change is available as a hotfix from Red Hat's Global Support Services. What this does is take the kernel tick rate (which defaults to 1000Hz) and divides it by the value of divider, to come up with an effective interrupt rate. You can verify that this is working by: Before making the change, use 'watch --interval=1 cat /proc/interrupts' and you'll notice that the timer interrupt is incrementing by 1000 every second. After you make the change, you you notice with the same command that it is incrementing via 1000/ every second. The vlaue of HZ that is exposed to modules is still 1000, thus not breaking module ABI. This same change is already present in RHEL5.1 today. In recent Fedora's, this is unnecessary due to the advent of the tickless kernel (which is useful for other reasons, including reduced power consumption on laptops). It is likely that RHEL6 will also be based on a tickless kernel. -- Stephen J Smoogen. -- CSIRT/Linux System Administrator How far that little candle throws his beams!

Problem is with clock, they are allways goinng forward faster then should. dmesg informs about : dev/vmmon[21623]: host clock rate change request 83 -> 1043 /dev/vmmon[21623]: host clock rate change request 1043 -> 83 /dev/vmmon[21623]: host clock rate change request 83 -> 1043 /dev/vmmon[21623]: host clock rate change request 1043 -> 83 /dev/vmmon[21623]: host clock rate change request 83 -> 1043 /dev/vmmon[21623]: host clock rate change request 1043 -> 83 all the time. I found on centos wiki information ,about vmware kernel running inside linux virtual machines to change frequency to 100hz. Is there any workaround for this issue? Thanks! David

iSCSI + CentOS 5.1 +_netdev problem
by Santi Saez 21 Apr '08

21 Apr '08

Dear Srs, I'm trying to automount an iSCSI device at system startup, this is the configuration: - CentOS 5.1, with kernel 2.6.18-53.1.14.el5PAE, i686 arch - iscsi-initiator-utils 6.2.0.865-0.8.el5 - iSCSI target is a Infortrend A16E-G2130-4 I have solved the "initial_login_retry_max" problem [1] and Open- iSCSI logs into Infortrend target without problems, with 10 retries in the parameter, but the partition is not automounted. Start scripts order appears OK: # ls -1 /etc/rc3.d/S* /etc/rc3.d/S07iscsid /etc/rc3.d/S10network /etc/rc3.d/S12syslog /etc/rc3.d/S13iscsi /etc/rc3.d/S25netfs /etc/rc3.d/S55sshd /etc/rc3.d/S90crond /etc/rc3.d/S99local But "_netdev" marked iSCSI device is not mounted, this is the fstab file: LABEL=/vz /vz ext3 _netdev,rw,noatime,nodiratime,commit=60,data=writeback 0 0 I have tried using LABELs, UUIDs, device names in fstab file.. and the problem is the same. If I put a "mount /vz" into "/etc/rc3.d/S99local" partition is mounted without problem.. I think the problem is in the "netfs" start script, I see no option to mount "_netdev" marked entries.. only a call to the command: (..) fsck -A -T -R -a -t opts=_netdev (..) I have solved the problem adding a "sleep 1" before the fsck execution: (..) echo $STRING sleep 1 fsck -A -T -R -a -t opts=_netdev rc=$? (..) Anyone with the same problem? What can be wrong? I have no problem with the same scenario on CentOS 4.6.. thanks!! Regards, -- Santi Saez

What is wrong with yum?
by Olaf Mueller 20 Apr '08

20 Apr '08

Hello, in my CentOS-Base.repo file there is a line baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch and yum update said 'nothing to do'. Then I change this line to baseurl=http://mirror.centos.org/centos/5.1/updates/i386 and yum updates firefox, squid, sos and so on. That happens on two of my computers, reproducible. Does yum sometimes forget it's release version? regards Olaf

New firewall, need mac changed
by Joseph L. Casale 20 Apr '08

20 Apr '08

I have read a few ways to do this, but not 100% sure. I need the interfaces reliably associated to the hardware (there are more than one), so the ifcfg-ethn has the mac address in it. I need to match the mac address of an old router that is about to be removed so I need not change any dns related config. Thanks! jlc

Logrotate problem after start of DST
by Bernd Bartmann 20 Apr '08

20 Apr '08

Hi, since the start of the daylight savings time my server has a problem with the log files. Sunday night the log files get rotated correctly, i.e. /var/log/messages gets /var/log.messages.1, /var/log/messages.1 get /var/log/messages.2, ... The problem now is that after log rotation new messages do no go to /var/log/messages, but to the rotated file. As DST started 3 weeks, the latest log entries now go to /var/log/messages.3. This happens to all other log files too. Even after rebooting the server new log entries go to /var/log/messages.3 instead of /var/log/messages. Any ideas why this happens and how to fix this problem? Thanks in advance, Bernd.

Another samba problem
by Anne Wilson 19 Apr '08

19 Apr '08

My server is CentOS with samba 3.0.25b. One client box runs Mandriva 2007.1 with samba 3.0.24. I can see the client box from the server, but the client box can't see the server. It can see the laptop on the same lan, though. Any suggestions as to what I could check? I know Craig said there had been some significant changes in recent versions. Are any of those changes likely to have an impact on this? Anne

Full Screen Mode
by John Wojnaroski 19 Apr '08

19 Apr '08

Hello, Just finished installing Centos5.1 on two machines (P4s, Nvidia graphics, Gnome desktop) Running OpenGL applications and need to run in full screen mode without any frame borders or window icons across multiple monitors. ( 4 monitors with two dual-headed Nvidia cards in twinview mode ) One machine works just fine, the other retains the Gnome frame and opens the apps in an X-term window. Have compared the X11 startup files, Xsession, scripts, Gnome settings, and can't find any differences. Obviously, I'm missing something, somewhere Under Debian things work just fine. Sure I'll eventually find it, but any help would be appreciated. Also is there anyway to turn off the update popup window? Not to cool when it shows up on the game screen.... Thanks John

Upstream vendor's diskless vs LTSP
by Fajar Priyanto 19 Apr '08

19 Apr '08

Hello all, I have a customer that insists of using upstream vendor's diskless (system-config-netboot) rather than LTSP. The reason is that he wants to use a 100% packages from the vendor, not from LTSP or any other party. I try the vendor's diskless system, and although it's very simple to setup, it lacks the support and/or documentation whereas LTSP is very good in it. Another sample is that he wants to connect a scanner to the client, I doubt it can be, since there's no documentation about it at all from the vendor. Is there any fundamental difference between the two setups?

Not able to run kernel-xen with megasr module :/
by Tomasz Nowak 19 Apr '08

19 Apr '08

I've managed to install CentOS 5.1 on S5000PAL with fakeraid Intel Embedded Raid Technology II Raid1 (LSI chipset) with some help of kickstart declaration 'driverdisk --source=http://.../driver.img' Then I've had some problems with yum update - new kernel didn't know about megasr.ko. I've solved it with commands: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5PAE/updates/ depmod -a 2.6.18-53.1.14.el5PAE mkinitrd /boot/initrd-2.6.18-53.1.14.el5PAE-new.img 2.6.18-53.1.14.el5PAE at last I've edited grub.conf add '-new' to initr definition. I'm not sure why I need to do that twice, but it finally worked.: # uname -r 2.6.18-53.1.14.el5PAE Now I need to install Xen, so: # yum -y install xen kernel-xen After installation I've tried the same command sequence: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5xen/updates/ depmod -a 2.6.18-53.1.14.el5xen mkinitrd /boot/initrd-2.6.18-53.1.14.el5xen-new.img 2.6.18-53.1.14.el5xen vi /etc/grub.conf (add -new, etc..) BUT xen kernel won'ts start. Kernel panic, 'unable to mount root', etc. Am I missing something? Is it possible to make it work? -- Tomek

I was using pfSense in a vm under esx but I want to move to Xen and prefer something that can run as a pv guest. Anyone got any reco's of what can run on top of CentOS to perform a similar role as pfSense (perform nat/pat and firewall etc between two interfaces)? Thanks for any ideas! jlc
