Modify kickstart initrd to add Buslogic driver
by Tom Brown 15 Feb '08

15 Feb '08

Hi I have a running kernel with the same kernel version of that in the kickstart that contains the Buslogic driver which would enable me to install a vmware client using kickstart. Is there an 'easy' way to take the initrd that contains the correct drivers and inject these into the initrd of the kickstart kernel? Or does anyone have a kickstart initrd available with the Buslogic drivers for an 2.6.9-55.ELsmp kernel? thanks Tom

CentOS5 installation crashes
by Andrew Henry 15 Feb '08

15 Feb '08

Im installing CentOS5.1 on an Acer Aspire 5021 laptop with AMD Turion64 and ATI X700 128MB gfx card. I want to partition my 80MB ATA disk as LVM, so I: Choose custom partition. delete all existing partitions. add one LVM vg partition taking up entire disk. I do not change any default options. I then click the LVM button to add my logical volumes as follows: 5GB / 8GB /home 5GB /tmp 4GB /var 1GB swap all are ext3 partitions. I exit the LVM dialogue and click Next to continue with the partitioning, and... it all crashes. I get a debug error box with lots of unintelligible errors that I am completely unfamiliar with. I click OK on the error dialogue and the installation freezes and I can only power off with the button. I will probably look for this on bug tracker and log a bug report if I don't find a similar case, but I wanted to mail the list first (because it's easier) and ask if anyone knows of the issue and how to get around it? thanks, andrew -- GnuPG Key ID: ECB18ABA Fingerprint: FDF3 91FC F5BC 1164 E217 315E 337E 219B ECB1 8ABA

PAE Kernel doesn´t boot
by i.anfrage 15 Feb '08

15 Feb '08

hi @all, i´m having big problems implementing a pae-kernel. i´m using centos5 on following hw intel core2duo 2,66 e6750 gigabyte p35-ds3p board 8 gb ram 4 * samsung_sata_hd501lj nvidia geforce 8500gt i can use a xen-pae kernel without having problems, but as i need to run vmware, it´s not a valid option to keep that kernel. the default kernel (which supports only up to 4gb ram) works fine, too. as soon as i boot a pae kernel the system stops booting at the point: "udev starting". i also can´t install the 64-bit version of centos5. i´ve tried the following kernels 2.6.18-53.1.4.el5PAE 2.6.18-53.el5PAE 2.6.18-53.1.6.el5PAE 2.6.18-53.1.13.el5PAE 2.6.18-53.1.13.el5xen 2.6.18-53.1.6.el5xen any suggestions??? tia!!! tom

Kernel 2.6.18-53.1.13.el5 fails on network.
by Steven Haigh 15 Feb '08

15 Feb '08

Hi all, After the latest lot of kernel security updates have come out, I updated one of my colo boxes and rebooted. It didn't come back up and fails when booting on: * CPU Microcode update * iptables * eth0 The booting process completes, however as you can imagine, there is no network connectivity at all. The only config changes were installing the new kernel. Booting back into 2.6.18-8.1.8.el5 make things work 100% again. The system is a dual P3 1Ghz with an e100 network card. Has anyone else come across this? Sadly, this is a headless box in an unattended colo - so I can't sit down and reboot upon reboot to try and figure out the cause of the problem. -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897

Apache2 crashes, MySQL uses upto 90% CPU
by Devraj Mukherjee 15 Feb '08

15 Feb '08

Hi everyone, I am running CentOS 4.6 and use the centosplus repo. Apache version 2.0.59 and MySQL 5.0.54 and for the past few days Apache 2 has been crashing randomly. The CPU usage has been maxing out (The machine has 2 x Xeon processors, with 4Gb RAM) and there are many httpd processes that appear to be defunct. I read around and found that logrotate may be crashing Apache if it doesn't quit in time. I have performance tuned MySQL to cache queries, modified php.ini not to use too many persistent connections, restricted the number of connections that Apache will answer to. Top says: 8136 mysql 16 0 202 51:55.73 5.7 680m 225m 5352 S mysqld Is there anyone else experiencing similar things? Any suggestions? Thanks for your time. -- "I never look back darling, it distracts from the now", Edna Mode (The Incredibles)

domain name display issue in linux pc

Hi, Thanks for your response on the kernel switching.I was away and could not reply immediately. Right now, I am facing a differentissue. I have to set up DNS server using BIND on Centos 4.3. When Itype the hostname on Centos, it shows: sipserver.vodcalocal.com But the cli prompt has root@sipserver~ meaning only the sipserver part of the hostname is displayed. whyis this so? What is the actual hostname then? I see in the /etc/sysconfig/network that thehostname is sipserver.vodcalocal.com the /etc/hosts file has the followingcontent: # Do not remove the following line, orvarious programs # that require network functionalitywill fail. 127.0.0.1 localhost.localdomain localhost sipserver 192.168.50.51 sipserver.vodcalocal.com The /etc/sysconfig/network has thefollowing config: NETWORKING=yes HOSTNAME=sipserver.vodcalocal.com I have seen in many forums that the/etc/sysconfig/network file has many other entries like domain name,gateway type, gateway ip etc, which are not present in myconfiguration. when i type $ domainname, i get-- (none) $ domainname -d vodcalocal.com $ domainname -f sipserver.vodcalocal.com Why does not the command domainnamelist the domain name? also domainname -f and domainname -d displaydifferent results. can the machine have the domainname and hostnamesame if I am going to run dns server on it? I run a SIP server on this PC whichneeds the domainname set but whenever I type echo $DOMAIN_NAME, itshows blank and I have to export the path variable DOMAIN NAME andset it. On another screen, I again dont see the domain name set. Howto set the domain name across all terminals and sessions andrestarts?an Thanks Padmaja

Backing up remote system
by Scott Ehrlich 14 Feb '08

14 Feb '08

I have an Overland Arcvault tape library, a CentOS 5 box, a Windows XP system, and RAID box that supports NFS and CIFS. The RAID box is remotely located and acts as central file storage. I might normally use dump to perform backups, but as was learned here, and on dump's man page, dump doesn't support remote file systems such as NFS or CIFS. So, for now, I've connected the library to a Windows XP system, running Service Pack 2. I have a shell script that tar gz's the directories of choice to preserve, places them in /backup, and, via samba's config of making /backup available, have it mounted as a drive letter on the XP system. I'm then using XP's built-in backup/restore program to store the contents of /backup to tape, and that is working fine for now. Is there a reliable Linux/CentOS-based way to do this, too? I know people keep saying use Amanda and/or bacula and be done with it, but in the event something goes wrong and the mysql, etc database gets corrupt, and people want their data back, it would be much easier to use a readily-available command, like cpio, tar, etc, to do the job. I've also elected to tar gz the contents ahead of time, for if I were to try and directly archive some of the files via a CIFS mount, I've experienced permission problems with various files and folders. A local tar of the files has gotten around that, then just have the Windows box copy the tar files to tape. Now to see what options tar has for producing incremental backups with a cron'ed tar job, unless someone has a better, comparable approach with existing OS tools (tar, cpio, dump, etc). I want to retain as many permissions as possible. I've tried rsync before, but that also requires enough disk space for the file copying, and some of the options I've used have complains of proper permissions being kept during the process. Thanks again. Scott

limit number of per-vhost or per-user cgi processes?
by J. Potter 14 Feb '08

14 Feb '08

Hi List, Is there a way to limit the number of cgi processes Apache's suExec will fork for a given vhost or given user? (either solution is fine) suExec doesn't honor the /etc/security/limits.conf nproc value. mod_throttle seems to be dead; and I can't figure out if selinux might be able to manage this (although would rather not flip selinux from permissive to enabled). What are others doing? Thanks! -Jeff

versions of the mail command
by Nigel Kendrick 14 Feb '08

14 Feb '08

Hi Folks, I am running postfix on a CentOS 4 box and was playing around with mail autoresponders. I came across a wiki article that did the trick, except for the following line which is what sends the auto response: mail -s"Subject here" -a"From: <$2>" $1 < /etc/postfix/autoreply.txt The (minor) issue is that the mail command doesn't have the '-a' switch to change the sender so I just removed that part. It's not a biggie but is there an updated version of the mail command or an alternative I could use that would pick up the sender's name variable and use it? Thanks Nigel Kendrick

ccache on CentOS?

Hi, Before using CentOS, I've spent a few years with Slackware. This distribution doesn't come with many packages, so I had the habit of building a lot of stuff myself. One of the first things I installed was ccache, a compiler cache that accelerates (re)building significantly. Has anyone ever setup ccache on CentOS? I'd be glad to find a little HOWTO. Cheers, Niki

Re: Disk partitions and LVM limits - SUMMARY
by Peter Blajev 14 Feb '08

14 Feb '08

Thank you all for the help. I'm writing this summary message because of people requests. I haven't tried all of this. I just collected it and organized it. You've got a big storage. Now what? The short answer is: "Just connect it. It should work." I'll play safe by saying that the following applies to <10TB storage. Some people reported file systems of 80TB. Things to watch out for: - Make sure the driver you are using or the storage itself don't restrict you from making big partitions or file systems. - fdisk creates partitions up to 2.1TB in size. Use "parted" instead. - RHEL5 supports up to 8TB ext3 file system. To create bigger then 8TB use option "-F" and 4K blocks. Your options are: - If the storage is connected to a RAID controller you can use the controller to create smaller logical partitions. Then combine them with LVM. - If you really want to partition the drive use parted. While partitioning if you run into this message: === sdb: very big device. try to use READ CAPACITY(16).

If you don't like parted you can still use fdisk to create a few 2TB partitions and then use LVM. - Use LVM on the raw device. Don't partition. This is what I did and it worked for me. Make sure you wipe out the MBR first: dd if=/dev/zero of=/dev/sdX bs=512 count=63 (count=1 should work too but 63 won't hurt either) Create the pv, vg and lv: pvcreate /dev/sdX vgcreate <vg name> /dev/sdX lvcreate -L <size> -n <name> -v vg_name Now you have to create the file systems.

using fping to find missing A records
by Rogelio 14 Feb '08

14 Feb '08

I have a specific question on how to do something, and a larger question addressing other "better" ways to do the spirit of what I'm asking. I'm setting up Nagios, and am trying to make sure that all of the subnets have A records, as IP addresses will be changing very, very rapidly, and when that day comes, I will not be here (but on another Nagios project). So, I'd like to create A records for each host. How do I "fping -a" a range of IP addresses, strip out the names of the name that the host replies with, and then ping that list of names? (You don't have to tell me how exactly, a general idea of which command line tools will do) I'm thinking something like: fping -g 192.168.1.0 192.168.1.255 -A | grep whatever > file, and then shove that file in another fping statement.

Strange performance issues under CentOS 5.1
by Alfred von Campe 14 Feb '08

14 Feb '08

I am still running CentOS 4.6 on our production systems, but I am starting to plan the upgrade to CentOS 5.1. I have one test system running 5.1 that is the exact same hardware configuration as my 4.6 test system. One of our builds runs about 6 times slower on the 5.1 system, even though is uses less overall CPU time. I first suspected something wrong with the disk, but the results from bonnie++ show that the 5.1 system is slightly faster: Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- -- Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec % CP /sec %CP centos4.6 16G 35933 10 21301 5 46507 6 41.8 0 Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- -- Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec % CP /sec %CP centos5.1 16G 42015 14 21179 5 49863 4 91.6 0 Then I ran the build with "/usr/bin/time --verbose", and here are the results (first 4.6 then 5.1): Command being timed: "make" User time (seconds): 32.15 System time (seconds): 3.52 Percent of CPU this job got: 99% Elapsed (wall clock) time (h:mm:ss or m:ss): 0:35.88 Command being timed: "make" User time (seconds): 22.05 System time (seconds): 3.11 Percent of CPU this job got: 11% Elapsed (wall clock) time (h:mm:ss or m:ss): 3:31.35 As you can see from the above, there is a lot of idle time on the 5.1 system.

upgrade from Fedora Core 5
by Peter Horst 13 Feb '08

13 Feb '08

Hi - It was recommended to me on the Fedora list that I consider upgrading to CentOS 5 from my present FC5 - the machine is used only as a light-duty CLI-only server. I have a couple of quick questions in that regard: 1. Is now a bad time to install CentOS 5, what with the root exploit out and about? Should I wait for a new kernel? 2. I just picked up a Cavalry 1TB external USB HD, the CADB001U32, which I want to use for backup purposes. I formatted it with one ext3 partition. If I load all my data onto that drive, then upgrade my main machine to CentOS 5 (which I assume will involve a complete wipe), should I then be able to mount it and retrieve the data? Thank you very much.

How can I stop the eject of the DVD after install?
by Lundgren, Andrew 13 Feb '08

13 Feb '08

I have created my own install DVD with a custom kickstart file and modified the isolinux.cfg file to allow the system to boot off of the hard disk as the default mode. It will also use my kickstart file if I select it. Now I would like to make the system not eject the DVD after reboot. The machines I am installing on do not have a motorized tray that can automatically pull the DVD back in when a mount command is issued. You have to push the disk in manually. As these machines will be unattended that is not idea. How can I prevent the installer from ejecting the DVD once the install is complete? Thanks! -- Andrew Lundgren

XFCE-Terminal can't display latin1 encoding
by Niki Kovacs 13 Feb '08

13 Feb '08

Hi, Much of my work consists in connecting to the MySQL monitor on our public library database server and working in it. Until recently, I've been using either Gnome-Terminal in GNOME, or Konsole in KDE. Since all the systems, both server and clients, default to fr_FR.UTF-8, and MySQL uses a default latin1 charset, I usually switch the displayed charset within Gnome-Terminal or Konsole. I'm actually converting most of the desktops to XFCE, since it's my preferred desktop environment. Unfortunately, XFCE's Terminal application doesn't seen to offer the opportunity to switch to displaying an ISO-8859-1 (or ISO-8859-15) charset. Is there any other way to achieve that? Right now, all my french characters in the MySQL console appear as inverted question marks. Which leaves me with two more inverted question marks in my eyes :oD Any suggestions? Niki

Apache RPM's
by Bob Boilard 13 Feb '08

13 Feb '08

Hello all, I love CentOS, but I am seriously regretting selecting Centos 4.4 for my production hosting servers. The current situation with CentOS 4.4 and being stuck at Apache 2.0.52 is a huge problem because of the new requirements for the Credit Card industry PCI scan. Apache 2.0.52 does not pass PCI compliance scans. which means no ecommerce on any of these servers - MAJOR ISSUE. So my question to the community is: when are new Apache RPM's going to be released or at minimum a backported version that plugs these security holes so we can pass PCI scans. Apache 2.0.52 has some major issues that need to be dealt with? Help us out here. I know I am not the only one in this situation. every hosting company that uses Ensim Pro X is just where I am. Any insight or better yet a solution to this would be great.

Re: [CentOS] Re: system gets suspended automatically!
by Ross S. W. Walker 13 Feb '08

I don't think that is the "harmless" error message mentioned in the release notes as that had to do with the "crash kernel". I saw this same error on a Dell AMD system. It seems the motherboard in that system didn't do ACPI IRQ routing as the kernel expected and experienced a lot of random problems until "acpi=noirq" was passed as a kernel option to disable ACPI IRQ routing defaulting back to the APIC IRQ routing. If that still gives you problems then you may need to use "irq=poll" which forces the kernel to poll for IRQ changes. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Wed Feb 06 08:03:47 2008 Subject: Re: [CentOS] Re: system gets suspended automatically!

I always use screen when running updates, installs, disk maintenance, etc. This way, if the ssh session dies for whatever reason, the command keeps going and I can reconnect to the session later.

Question on failing hard drive part 2
by Jimmy Bradley 12 Feb '08

12 Feb '08

OK, I've figured out which drive is bad. Before I go any further let me give a brief HD configuration explanation. The primary IDE has a 80gig(Master) HD, and an internal zip drive(Slave) connected to it. The two 200gig Hard Drives are connect to a PCI ATA controller card(Not a promise card), one is master, the other one is slave. It is the slave 200gig drive that is going bad. Now, I have a feeling this would be too easy. When I set the machine up, Cent OS set the drives up using LVM. I only have about 20 to 30 gigs of data saved on the machine right now. Maybe not quite that much. Like I said, I have a feeling that hoping this will work would be too easy, but what do you think my chances would be, that I could disconnect the drive that is going bad, boot the machine up, and it fully boot up, and all my data be intact, and LVM automatically resize the home partition down to around 200gigs instead of 405gigs?

Making FORWARD_IPV4=YES permanent / DHCP multiple routers
by Tim Alberts 12 Feb '08

12 Feb '08

First, I'd like to configure my system to forward ip, to act as a gateway for my network. I've always used a script during startup to do this: echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o ${UPLINK} -j SNAT --to ${IP_NAT} This works fine, however I want this permanent so I don't have to run the script on startup. I have the firewall setup with SNAT fine, but when I write the file /etc/sysconfig/network with the line 'FORWARD_IPV4=YES' it still doesn't enable the ip forwarding after boot? cat /proc/sys/net/ipv4/ip_forward 0 So how do I do this? Second, In DHCP, you can specify multiple DNS servers: option domain-name-servers 10.0.0.1, 10.0.0.2, 10.0.0.3; can you also do this with routers? option routers 10.0.0.1 10.0.0.2; so that if one is down, the network PC's can fail over to another?
