Does kernel-devel need further configuration after yum install, for driver build ?
by MikeW 30 Nov '06

30 Nov '06

In order to build a kernel module outside of a kernel source tree, I understand it is necessary to set up a makefile containing lines such as ... obj-m:=driver.o ... and quote the KERNELDIR directory to the make system (e.g. see O'Reilly book on Linux device drivers) However, doing this with Centos either 'as-is', or even after doing a yum remove kernel-devel-<version> then yum upgrade kernel-devel, (to cause a reinstall of the latest version) leads to a series of error messages, e.g.: In file included from include/asm/smp.h:18, from include/linux/smp.h:96, from include/linux/sched.h:23, from include/linux/module.h:10, from /home/fred/appbuild/mydriver/mydriver.c:22: include/asm/mpspec.h:6:25: mach_mpspec.h: No such file or directory although I am not set up for SMP ! These errors are 'fixed' if I add to the make's CFLAGS, -I$(KERNELDIR)/include/asm-386/mach-default but I would guess that this should really happen by means of some symlink trickery, which was set up when the package gets installed. I do not think that everything else is correct if I do this ! Am I missing another installation step ? Thanks. MikeW

I just finished setting up an OpenVPN server on CentOS 4.4. It was really quite simple once I figured out the basics. The hardest part was configuring everything so that the remote computer could communicate with the rest of the network. There is some good information on the OpenVPN website. http://openvpn.net/howto.html -- Bowie

RE: [CentOS] Re: hostname setting
by Ian Anderson 30 Nov '06

/etc/sysconfig/network is what assigns the hostname to your particular server. This is also where CentOS writes the hostname when you initially install the OS. /etc/hosts provides a mechanism for mapping that hostname to an IP address. This is one of several ways to map ip's to hostnames. I use /etc/sysconfig/network to "name" my machines and then enter that value into /etc/hosts. i.e. /etc/sysconfig/network HOSTNAME="vpn-gateway" /etc/hosts 127.0.0.1 localhost localhost.localdomain 10.0.0.1 vpn-gateway vpn-gateway.mydomain.com the second entry is an "alias" to vpn-gateway. If you were to ping either one you would get a response from 10.0.0.1. There is an order of operations that CentOS uses to resolve host names. By default the first attempt is in the hosts file. If it doesn't find anything there is will try DNS, if nothing is there it will try WINS, and so on. If you have a DNS server in your network you could add a record to resolve vpn-gateway.mydomain.com to 10.0.0.1 and not fill in a /etc/hosts value at all. (Providing /etc/resolv.conf is setup to look at that DNS server) Someone correct me if I am wrong, but this is what I understand to be correct. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Scott Silva Sent: Wednesday, November 29, 2006 2:02 PM To: centos(a)centos.org Subject: [CentOS] Re: hostname setting MrKiwi spake the following on 11/29/2006 1:34 PM: > Can someone with far more knowledge than me help here? > > I have a co-worker with a question; > " > Where should i set the server's hostname? > There seems to be multiple places and i don't understand the differences. > 1. # hostname mailserver.mydomain.com > 2. # echo "127.0.0.1 mailserver mailserver.mydomain.com">>/etc/hosts > 3. # vi /etc/sysconfig/network, add "HOSTNAME=mailserver.mydomain.com" > > So far i think i understand that postfix likes to see the hostname in > the hosts file, but things i have read imply that postfix is pretty > clever at working it out from multiple places. > Apache also seems to be clever, but the conf file recommends that you > hard code the server name into the config.

dhcpd
by Daniel Teixeira 30 Nov '06

30 Nov '06

Hi im trying to configure centos to run as a dhcpd daemon but it simply doesnt work I'm using the default configuration file from dhcdp (and tried multiple alternatives). problem is that pxe clients do not aquire dhcp addresses in the log i can see that there are 3 or 4 dhcp offers per boot atempt but no dhcp requests anyone? i'm going crazy here... .i've tryed 3 diferent machines (servers) and 4 or 5 diferent clients sometimes windows clients are able to catch the ip but only sometimes. maybe this is a route problem? the machine(s) was freshly installed with centos 4.3 please advise!

SCSI drive offline
by guojinpeng(郭晋鹏) 30 Nov '06

30 Nov '06

I’m running centos 4.3 (2.6.9-22.ELsmp) on a box ,and running windows XP on vmware 5.5.1. I have 3 scsi disk on this server,sda for linux system,sdb for vmware disk,and sdc for other. Resently I found that something wrong with the second disk,the guest os windowsxp copying files from a samba server(another box) to it’s disk,and for some time,maybe 5hours,3or1hours, the kernel said that sdb is offline… then I reboot,everything is ok,no filesystem check. but this problem accours every a few hours when the windowsxp copying a lot of files to it’s disk. I’m not sure if it was the heavy load of the disk made this problem. then I run smartctl to see if it’s overheat,but result nothing,smartctl said the temperature is ok (27-29c). is it a hardware problem? cable? disk is dying? kernel problem?vmware problem? and here is the dmesg dump when this problem happening..

Copying user accounts (passwords) to another server
by Nigel Kendrick 29 Nov '06

29 Nov '06

Hi Folks, I am doing a server swap out tomorrow and wondered if there was a utility that will copy user account details and their current passwords from one server to another (both CentOS 4) - there's only about 15 to do so it's not a major issue. Thanks Nigel Kendrick

hostname setting
by MrKiwi 29 Nov '06

29 Nov '06

Can someone with far more knowledge than me help here? I have a co-worker with a question; " Where should i set the server's hostname? There seems to be multiple places and i don't understand the differences. 1. # hostname mailserver.mydomain.com 2. # echo "127.0.0.1 mailserver mailserver.mydomain.com">>/etc/hosts 3. # vi /etc/sysconfig/network, add "HOSTNAME=mailserver.mydomain.com" So far i think i understand that postfix likes to see the hostname in the hosts file, but things i have read imply that postfix is pretty clever at working it out from multiple places. Apache also seems to be clever, but the conf file recommends that you hard code the server name into the config. If you don't, where does apache look? If you set the hostname during an install, where is that written? If i use method 1 above ("hostname mailserver.mydomain.com") i seem to have to do that at every boot (or script it of course) whereas the edit to /etc/hosts or /etc/sysconfig/network would survive restarts. I have read the information in "man hostname" and understand that "hostname -f" gets its info from the hosts file, but where does the function "gethostname" get its info from? Finally - which method do you all use to set you hostname? " Thanks all, MrKiwi

Iptables front-end
by Jordi Espasa Clofent 29 Nov '06

Hi all, ¿What iptables do you use to manage iptables? ¿Or maybe not? Simply curiosity, so I'm coming from openSUSE and in that distro there is a YaST module front-end (YaST firewall).

Disable IPV6
by Tom Brown 29 Nov '06

29 Nov '06

Hi On a CentOS 4.x box how does one disable IPV6? Is adding "alias net-pf-10 off" to the end of modprobe.conf and a reboot still the 'standard' way of doing this ? thanks

Gents, I am trying to do a "gcc -m32" on a x86_64 box. gcc -m32 /tmp/jj.c /usr/bin/ld: crt1.o: No such file: No such file or directory collect2: ld returned 1 exit status This is the error I get. I did a "yum install glib.i386" successfully. there is no "yum install glib-devel.i386". How can i get a "gcc -m32" compile on my x86_64? THanks, Jerry

Hi there.... Has anyone seen a tutorial around for a pptp server (on the same server as the firewall) for centos/rhel 4? I have been following a few general tutorials for POPTOP, but nothing seems to really work as of yet. Thanks!

kernel and iptables with l7-filter
by David Hrbáč 29 Nov '06

29 Nov '06

Hi, those who are interested in l7-filter on C4.4, here is the testing repo. http://homen.vsb.cz/~hrb33/el4/hrb/testing/i386/RPMS/repodata/ Kernels and iptables RPMS are compiled with l7-filter. Feel free to test and send the reports. Packages are not signed, not even with special release version. Should be fixed on final release. New release should also include IMQ, ESFQ. Iproute is the only package compiled with ESFQ for now. Regards. David Hrbáč

Any long-time CentOS users on list using Ubuntu as well?
by chrism＠imntv.com 28 Nov '06

28 Nov '06

I've gotten roped into helping a local charity with some computing/infrastructure snafus. It seems their last good Samaritan installed Ubuntu all over the place and is "unavailable" now to clean up the mess. CentOS has made me somewhat lazy because everything just works out of the box for the most part and you've got the occasional "yum update". :) These are all desktop systems, if that makes any difference. With any luck, I'll be able to pave over the installs with CentOS 4.4 and call it a day. :D Any suggestions on known piles of doodie to step over would be very much appreciated. <g> Best regards,

Confirming Multi-Processor
by Jack Murgia 28 Nov '06

28 Nov '06

I have a test bed server that's pretty old- PIII Dual 550. I've done yum update kernel-smp and when I run cat/proc/cpuinfo it lists both processors- is there anything I need to to to confirm that it's fully utilizing both processors? I ask this because under the old OS (Fedora Core 2) I always saw an error message at boot that said something about operating in single-processor mode because the firmware was pre-2001. I don't see this error in CentOS. The last firmware available for this logic board (N440BX) is dated 1999.

Hi all, [Resent here, because it is off-topic on centos-devel] According to [1] the project has arranged a stand at FOSDEM. Are things 'definite' enough to start booking a hotel/hostel?

Get error msg if try to use kernel makefile / build kernel
by MikeW 28 Nov '06

28 Nov '06

Using the new method for building a standalone kernel module (although seems to happen with the traditional way as well) I get "mach_mpspec.h: No such file or directory" Same result if I try to do a kernel 'make'. Subsequently I get MAX_MP_BUSSES and MAX_IRQ_SOURCES undeclared. This should surely work 'out of the box' with Centos ? Any ideas about what's missing ? Thanks, MikeW

Centos-4.3: Filelocking problems under high [network related] load with kernel 2.6.9-42.0.3.ELsmp
by Martin Knoblauch 28 Nov '06

28 Nov '06

Hi, first of all, please CC me on any reply, as I am only subscribed to the digest. OK. Here is the problem. Said kernel (from 4.4) seems to have problems with file-locking when the system is under high, likely network related, load. The symptoms are things using file locking (rpm, the user-space automounter amd) fail to obtain locks, usually stating timeout problems. The sytem in question is a HP/DL380G4 with dual-single-core EM64T CPUs and 8GB of Memory. The network interfaces are "tg3". It happens with both CentOs and RHEL4. The high load can be triggered by copying three 3 GB files in parallel from an NFS server (Solaris10, NFS, TCP, 1GBit) to another NFS server (RHEL4, NFS, TCP, 100 MBit). The measured network performance is OK. During this operation the systems goes to Loads around/above 10. Overall responsiveness feels good, but software doing file-locking or stuff like opening a new ssh connection take extremely long. So, if anyone has an idea or hint, it will be highly appreciated.

Turn an ext2 filesystem into a component of a mirrored RAID?
by Bart Schaefer 28 Nov '06

28 Nov '06

We have a CentOS 3 server with about 300GB of data on an ext2 filesystem that we need to mirror onto a new drive, which we're then going to pull out and put into a second server. A straight disk-to-disk copy (with rsync, tar, or "cp -a" doesn't much matter) manages about 75MB per minute, which would take almost three days, and the system gets very sluggish while such a copy is going on, so we can't afford to just let it run. Is it possible, without loss of data, to convert the existing ext2 filesystem into a mirrored software RAID, then add the new drive as a second device and let rebuilding the RAID take care of making the copy? Even if this took more time, we've had good overall system performance with software RAIDs rebuilding in the background before, so it could run as long as necessary. We'd then need to be able to remove the second device from the RAID and either convert it back into a plain ext2 or put it into a similar software RAID in the destination machine. Is this possible? Is there another plan that would make more sense? Thanks in advance for suggestions.

startx reboots my computer
by Ted Miller 28 Nov '06

28 Nov '06

Well, sometimes startx reboots my computer. Other times is does nothing except slow it to a halt for a while. Sometimes is locks up. I am using init level 3. At the command line, everything looks fine, and I can do whatever commands I want. When I type startx, then things go down the tubes. What doesn't happen: X never starts No error messages get posted to dmesg no log is generated in /var/log/xorg.0.log What DOES happen: on a good run, I get the error message: /usr.../startx: fork: resource temporarily unavailable on a bad run the computer either locks up or reboots, or I get a parade of notices that the comp is "out of memory, shutting down process xxxxxx". running top -u tmiller -b>/tmp/top.log in another console generates a huge file. After deleting the process entry lines (all end in startx, except the bash line), I get results like this: top - 22:27:23 up 3 min, 2 users, load average: 0.03, 0.07, 0.03 Tasks: 66 total, 1 running, 65 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 100.0% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 1024380k total, 178112k used, 846268k free, 14720k buffers Swap: 8385848k total, 0k used, 8385848k free, 97316k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4517 tmiller 21 0 53976 1604 1188 S 0.0 0.2 0:00.00 bash top - 22:27:26 up 3 min, 2 users, load average: 0.03, 0.07, 0.03 Tasks: 367 total, 5 running, 362 sleeping, 0 stopped, 0 zombie Cpu(s): 3.3% us, 7.3% sy, 0.0% ni, 88.7% id, 0.7% wa, 0.0% hi, 0.0% si Mem: 1024380k total, 251008k used, 773372k free, 14736k buffers Swap: 8385848k total, 0k used, 8385848k free, 97320k cached top - 22:27:29 up 3 min, 2 users, load average: 0.51, 0.17, 0.06 Tasks: 3389 total, 3 running, 3386 sleeping, 0 stopped, 0 zombie Cpu(s): 35.8% us, 64.2% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 1024380k total, 985600k used, 38780k free, 14740k buffers Swap: 8385848k total, 0k used, 8385848k free, 97368k cached ************************************************************************ eventually peaking out at: top - 22:28:15 up 4 min, 3 users, load average: 2.54, 0.74, 0.26 Tasks: 7696 total, 2 running, 7693 sleeping, 0 stopped, 0 zombie Cpu(s): 10.5% us, 45.2% sy, 0.0% ni, 0.0% id, 43.8% wa, 0.0% hi, 0.6% si Mem: 1024380k total, 896720k used, 127660k free, 264k buffers Swap: 8385848k total, 1035964k used, 7349884k free, 10372k cached *************************************************************************** with the PID numbers peaking at 12551, tasks at 7696, swap at 1-1.4GB used.

using remote vnc on centos 4.4
by Jerry Geis 28 Nov '06

28 Nov '06

Is there a method so on a remote vnc connection the screen is not being shown to those where the monitor is located. If I am remoting in I dont even want the screen that is blank due to screen saver, to even show anything. remote does not need the screen at all in my case. Is there a way to do that? Jerry

Graphics aid needed for the CentOS-5 efforts
by Karanbir Singh 28 Nov '06

28 Nov '06

We need a bit of help with the design and graphics in CentOS-5, people interested in helping out should get in touch with me or any of the CentOS developers, either here on the List, or email or via the irc channels. If you are a graphic designer or can do a bit of decent artwork stuff, now is the time to get involved with the project, and help make it a bit better :) - KB -- Karanbir Singh CentOS Project { http://www.centos.org/ } irc: z00dax, #centos(a)irc.freenode.net

Strange system hangs
by Alfred von Campe 27 Nov '06

27 Nov '06

I've had a couple of complete system hangs on two different systems in the last couple of weeks. The first time it happened I shrugged it off, but now that it has happened a second time on a different system I need to investigate this a bit. further All the systems are identical: IBM (Lenovo) ThinkCentre M52 with 3GB of memory, running CentOS 4.4 with all the recent updates. The systems are currently running the 2.6.9-42.0.3.EL kernel (IIRC, the first hang happened with the 2.6.9-42.0.2.EL kernel). When it occurs, the system is completely hung. Whatever was on the screen at the time continues to be displayed, but the machine doesn't respond to pings (so you can't ssh into it), the mouse is frozen, you can't get to the alternate consoles (Ctrl-Alt-F1), etc. In other words, the only recourse is a reboot. There is absolutely nothing in /var/ log/messages or any other log files that I could find after the reboot. In both cases, the users report that they were editing a file when it happened (they weren't even trying to write out changes to disk). Anybody else seen anything similar to this? Any recommendations on how to capture all relevant information should this occur again? How would you debug a problem like this? Alfred

Port multiplier support in megaraid* module for LSI LOGIC LSI00042 PCI-X SATA II Controller?
by Mike Fedyk 27 Nov '06

27 Nov '06

I have tried many permutations of search terms in google and I haven't been able to find any confirmation that the megaraid* modules in centos4 supports port multipliers/multiplexers. Here is a link to the controller I have in mind at newegg: http://www.newegg.com/product/product.asp?item=N82E16816118032 In case anyone is interested, here is what my research has turned up when looking for external JBOD SATA enclosures: I'm just looking for a hot swap JBOD enclosure, so anything over $1000 USD is out of the question. Luckily, I found a few meeting that criteria. The DS-1220 is rackmountable, holds 12 drives and uses two port multipliers. The only drawbacks I can see is that it looks like they could've fit 15 drives with three multipliers, and two drives need direct connections to the controller. That's 4 esata ports used ( 2 x 5 port multiplier + 2 direct to hard drive ). http://www.norcotek.com/item_detail.php?categoryid=8&modelno=DS-1220 The SC-SATA12RM is rackmountable, uses 4 multi-lane SAS connectors and holds 12 drives. Having full bandwidth to each drive can have its advantages for streaming reads and writes, but the seeky workload I expect won't benefit much from the extra theoretical bandwidth. In order to save on sata controller port usage, I'd probably have to get a few port multipliers. http://www.pc-pitstop.com/sata_enclosures/scsata12rm.asp The SC-SAT10PM holds 10 drives, uses two port multipliers, connects to the SATA HBA with 2 esata connections (and may be rack mountable with some customizations -- I need to check further). Because of the area the server and storage will be in, the enclosure doesn't strictly need to be rack mountable. http://www.pc-pitstop.com/sata_enclosures/ Here are some links to esata to sata, sata multilane/sas to four internal sata ports, etc. port converters: http://www.satacables.com/html/sata-pci-brackets.html http://www.cooldrives.com/intoexes4pop.html http://www.lycom.com.tw/ST130.htm

Which greylisting milter?

Howdy. Over at http://greylisting.org/implementations/sendmail.shtml they list 5 different implementations - 1 perl and 4 C based. Does any one know if one is better than the other? Does it make a difference? Is it just a matter of preference? Thanks. Zyxian _________________________________ I learn more when something goes wrong...

ISCSI SAN suggestion
by Radu Radutiu 27 Nov '06

27 Nov '06

Sorry for the off-topic question but I need advice on a buying a ISCSI SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN is to store email accounts (that will be accessed by imap - dovecot) and other documents. Minimal redundancy is required (e.g. dual power supplies, battery backed write cache or mirrored controllers) and price for a 2 TB configuration should be under $ 10000. Right now the short list includes Promise VTrack M300i and Dell/EMC AX150i. Do you have any experience with any of these models or can recommend a similar SAN that will meet the above requirements? Regards, Radu

Looking for assistance
by System Admin 27 Nov '06

27 Nov '06

We have about 5 servers spread out throughout the country: 2 Centos 4.4, 1 Red Hat and 2 windows machines- looking for some good ideas for a back-up solution. Our servers hold a lot of data, but only a small portion of it is crucial on any given day. That crucial portion is always changing (for example, this week the crucial files all relate to November- current and previous projects, and the next project in early December). What we need to have is a backup solution that would allow us to roll back to any given day (about four weeks of daily history). Bare-metal backups are a must. Our ideal solution would be to find someone who could design and implement a system for us. All ideas and suggestions are welcome.

cluster service
by John R Pierce 25 Nov '06

25 Nov '06

I've setup the CentOS version of the RH Cluster Service on a pair of centos 4.4 i386 test boxes... wanting to do high availabilty stuff. its working, I've added a virtual IP and a fiberchannel hosted e3fs file system thhat either can mount, if I manually crash or reboot one, this IP and FS mount on the other, awesome. the servers are connected to the storage via a QLogic SANbox 5600 fiberswitch, and I've added a SANbox2 'fence device' to the cluster, with its IP and login/password... but I don't understand how to configure the SANbox or the fencing agent so that it knows how to map these two servers to the zones or zonesets on the SANbox. right now everything on the SANbox is in the same zone (these two plus a few other servers plus the shared storage controller which also has some LUNs that are only accessible by a couple Sun servers running Solaris). what am I missing? I did see the man page on fabric_sanbox2, but dont see how that applies via system-config-cluster ...

"undefined symbol: _pam_make_env"
by ness 25 Nov '06

25 Nov '06

Hello, A while ago I downloaded and compiled PAM 0.99.x and installed it over the default CentOS PAM installation. Of course, this premature decision led to root and FTP access being fully locked down and inaccessible. When I `su -`, it prints "su: incorrect password" before it gives me the chance to type a password. When I `sudo su -`, it prints "sudo: pam_authenticate: Module is unknown". The most elaborate error from that point on is in /var/log/secure, which prints the following when I supply valid FTP log in credentials: Nov 24 19:57:07 ded sudo: PAM unable to dlopen(/lib/security/pam_stack.so) Nov 24 19:57:07 ded sudo: PAM [error: /lib/security/pam_stack.so: undefined symbol: _pam_make_env] Nov 24 19:57:07 ded sudo: PAM adding faulty module: /lib/security/pam_stack.so I've tried reinstalling PAM via yum, it's dependencies, and it's furthest dependencies with no apparent success. Does anyone know how this can be fixed without formatting the entire system? Thanks, --ness

Need SAN suggestion
by Mindaugas 25 Nov '06

25 Nov '06

Hello, It is not total off-topic since almost all connected servers will be RHEL and CentOS. :) We are considering to purchase new storage system. The most probably we will be choosing between HP (EVA6000), EMC (CX3-20C) and Hitachi (similar model). iSCSI connection is also required. What are your experienced with listed systems? What to avoid? What ot expect? Now I just know that sequential read/write preformance on EVA is poor. :) Thanks, Mindaugas
