SNMP Log entries
by Enyo 30 Nov '07

30 Nov '07

Hi, Does anyone know how to prevent snmpd from writing the below into /var/log/messages/ Nov 29 19:35:02 serenity snmpd[2287]: Received SNMP packet(s) from UDP: [127.0.0.1]:34309 Nov 29 19:35:02 serenity snmpd[2287]: Connection from UDP: [127.0.0.1]:34309 Nov 29 19:35:02 serenity last message repeated 7 times Nov 29 19:40:02 serenity snmpd[2287]: Connection from UDP: [127.0.0.1]:34313 Nov 29 19:40:02 serenity snmpd[2287]: Received SNMP packet(s) from UDP: [127.0.0.1]:34313 Nov 29 19:40:02 serenity snmpd[2287]: Connection from UDP: [127.0.0.1]:34313 Nov 29 19:40:02 serenity last message repeated 7 times Nov 29 19:45:02 serenity snmpd[2287]: Connection from UDP: [127.0.0.1]:34319 Nov 29 19:45:02 serenity snmpd[2287]: Received SNMP packet(s) from UDP: [127.0.0.1]:34319 Nov 29 19:45:02 serenity snmpd[2287]: Connection from UDP: [127.0.0.1]:34319 We query the server to gain load stats etc every 5 mins and this is causing /var/log/messages to fill up pretty quickly/ I do not care about seeing normal connection info from snmpd, but retaining logging for other info such as malformed packets, bad community strings etc is of interest. Thanks

RAID, LVM, extra disks...
by Ugo Bellavance 30 Nov '07

30 Nov '07

Hi, This is my current config: /dev/md0 -> 200 MB -> sda1 + sdd1 -> /boot /dev/md1 -> 36 GB -> sda2 + sdd2 -> form VolGroup00 with md2 /dev/md2 -> 18 GB -> sdb1 + sde1 -> form VolGroup00 with md1 sda,sdd -> 36 GB 10k SCSI HDDs sdb,sde -> 18 GB 10k SCSI HDDs I have added 2 36 GB 10K SCSI drives in it, they are detected as sdc and sdf. What should I do if I want to optimize disk space? The simplest solution would be to create /dev/md3 out of sdc1 and sdf1, and add it to the VG, and increase the size of my /vz logical volume. However, if I could convert that to a RAID5 (it could be possible to re-install, but I would rather not), I could have 6 drives in RAID5, so I'd have 5x36 GB (180) of space available total, instead of 3*36 (108). Also, please note that this is a Dual PIII 1.2 Tualatin. I'm runing OpenVZ with virtual machines that are not really CPU expensive, but I would not like to see my processors spending most of their time computing XORs for the RAID5. Any suggestions/tips welcome. Regards, Ugo

I had it working for a while but it kept getting in the way when I was trying to get the bcm43xx module working. I went back to my old system of just having eth0 for the wired connection and eth1 for wireless and user controllable. Other than my home network, I don't have any other wireless networks that I connect to on a regular basis so this approach lets me manually control what happens when I'm trying to connect to some oddball network that I've never seen before and probably won't see again. One thing I remember about getting NetworkManager and the piece that handles keys (not gnome-keyring; don't remember the name right now and the laptop is off) was to tell that piece to use the generic wireless kernel API instead of the ndiswrapper control interface. Seems weird but it worked. If you need more information, I can fire up the laptop at some point. Cheers, Dave -- Politics, n.

reasons for using CentOS in business environments
by Rogelio 29 Nov '07

29 Nov '07

My apologies if this question has been previously answered, but could anyone here provide me with resources that I might use to help build a case for exclusively using CentOS in an enterprise environment? (Approximately 200 servers) Long story short, I've used a little of everything out there (Gentoo/Debian/*BSD/Slackware) and have a fairly good overall strategy of how they all work (all of them have lived on my laptop at one time or another over the last 10 years or so), but I'm now looking for solid business reasons that I can present to the CxO types of a company to show them that CentOS is probably where they'd like to look. Reasons thus far I've come up with include: --free *and* "fully" (at least, in my experience) compatible with RHEL --fairly stable (I don't have problems unless I start mixing repos) --yum packages (almost as cool as Debian! Ok, I'm biased...or maybe I don't know how to properly use yum?) Any other suggestions / tips I might add to my list would be greatly appreciated!

heartbeat segfaulting on CentOS 5 x86_64 (xen guest)
by Amos Shapira 29 Nov '07

29 Nov '07

Hello, I'm having trouble running two linux-ha heartbeat nodes and have them talk to each other (or actually one of the nodes just doesn't work even for local basic admin stuff, including a simple "service heartbeat stop") and apparently it all boils down to the following Bug in Linux-HA: http://developerbugs.linux-foundation.org//show_bug.cgi?id=1678 I'm persuing this with the linux-ha users mailing list but the bug doesn't seem to get much attention from the linux-ha developers and I was wondering whether anyone here has stumbled on it and have a work around. The strange thing is that the two noes are identical - both are CentOS 5 PV Xen guests on the same CentOS 5 Dom0 host and exactly the same packages and config files - but one of them seems to work perfectly while the other doesn't. Anyone? Thanks, --Amos

2 DHCP server in one subnet
by Fajar Priyanto 29 Nov '07

29 Nov '07

Hello all, In the network there is already a W2K server serving as DHCP server for the network. Then we want to implement LTSP, so we need to setup another DHCP server, right? Due to unexpected reason (little by little migration of w98 clients to LTSP), we need to keep the W2K server running in that network. Can we then have 2 DHCP server in the same subnet, only serving pre-determine clients using mac address? Any clue on how to setup the dhcpd.conf? Thank you very much. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 20:16:32 up 14 min, 2.6.22-14-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn.

Severe VMware slowdown
by Mark Hull-Richter 29 Nov '07

29 Nov '07

In the last few days, I have noticed a drastic slowdown in my VMware Windows guest OS.. I recently bit the bullet and upgraded it from XP SP1 to SP2, and that seemed to work fine for quite a few days. The two major changes I made to the system recently were: 1) The most recent update from CentOS (can't remember which one, but it was within the last two weekd for 5.0). 2) Adding another VM guest OS, this one a CentOS 5.0 guest. What happens is, usually when I click the mouse in the Windows window, the system hangs up completely for some period of time that usually exceeds four minutes. Thereafter, once the VM is "running," it will occasionally just stop when I am transitioning into the VM from elsewhere. I verified this using the CentOS system clock - last night it stopped at 23:01 and still read 23:01 when my cell phone, which is usually dead on in sync with the system clock, read 11:04pm. I cut back on the amount of memory allowed to the Windows VM (768MB, down from 1GB) and that seemed to help a little, but I have 2GB and I'm thinking that this should not be a problem. Any input would be helpful. Thanks. mhr P.S.: Now I'm thinking that my earlier remark about applications was a bit overstated....

Adobe products under Linux?
by Scott Ehrlich 29 Nov '07

29 Nov '07

Also sent to Codeweavers - [what is this list's insights?] I have a 32 GB, dual quad-core desktop machine and was considering 32-bit Windows XP w/SP2, but discovered it only supports up to 4 GB RAM, so that idea is shot. Next in line is 64-bit CentOS 5. The major need for Windows would be very active use of Adobe Acrobat 8, Photoshop CS3, and Illustrator CS3. There may also be the need to copy/transfer information among Matlab, Mathematica, and Microsoft-based applications, from Office 2003 to the above-mentioned ones. Do you support these, and how complete is your product line for 64-bit CentOS 5? Based on your answer, I'll know whether to go with a virtual machine-based solution, which means a Windows VM, or can remain Linux-only, with your solution. Thank you very much. Scott

Help with file descriptor
by Guy Boisvert 29 Nov '07

29 Nov '07

Hi all! I have a problem with CentOS 4.4 and Communigate Pro 5.0.9. As our user number grows, we are seeing "too many files open" error messages in Communigate logs. I spoke with Communigate tech support and they asked me to increase the number of file descriptors which i did. I put 128000 as a script i made to check Communigate open files reported as high as 99000. As i checked the Communigate log file, it reported that it "sees" 1024 "available" file descriptors. Reporting that to Communigate tech support, the guy answered: "CommuniGate gets this number via getdtablesize() system call. Probably in CentOS the table has a fixed size so you need to recompile the kernel to expand it. Try upgrading CentOS to 4.5 (or whatever later version is available) " I'm a little afraid of upgrading the server right away, i don't want to worsen the problem. Or maybe it's safe to do it. I dunno. Is there anybody on the list that can comment on what the Communigate tech support guy said about the "getdtablesize" thing ? Thanks in advance! Guy Boisvert

Mail Server Install
by Jun Salen 29 Nov '07

29 Nov '07

Hi Friends, I am planning to upgrade my mail server from CentOS4.5 to CentOS5. By this, I also planned to replace my postfix mail server with Scalix although the community edition limit me to just 25 premium user, I think it is suffice for us with the remaining user as standard user (with approx. <> 100 users total). Is there a catch on using Scalix based on your experience. I see that Horde is available from Dag's repository, do you think it is better for me to use that instead? Is there anyone using it that may share their gotchas and good points from their experience for me to prepare and be ready. Thank you in advance. junji aisalen.wordpress.com Linux Registered User #253162 Send instant messages to your online friends http://uk.messenger.yahoo.com

Some would say Fedora users are nuts. I think you perfectly described my experience with Fedora on my laptop (HP zv6015). I managed to coerce Fedora 4 onto it (even the install was wonky until I learned about nofb). I got tired of chasing the latest Fedora release and moved to CentOS 5 when it was released. I built a custom kernel for a while so the card reader would work until enough fixes got back ported that the stock kernel would read the SD card my camera uses. Now everything (sort of) "just works (TM)". I say "sort of" because I'm still running ndiswrapper since every time I've tried the bcm43xx kernel module it hasn't worked with my WAP. With CentOS 5 the laptop seems to be as stable as my desktop. About the only time I ever boot the Windows XP Home partition is if there's a BIOS update or something that HP doesn't release any other way. Can't imagine torturing myself with XP.

Also sent to Codeweavers - [what is this list's insights?] I have a 32 GB, dual quad-core desktop machine and was considering 32-bit Windows XP w/SP2, but discovered it only supports up to 4 GB RAM, so that idea is shot. Next in line is 64-bit CentOS 5. The major need for Windows would be very active use of Adobe Acrobat 8, Photoshop CS3, and Illustrator CS3. There may also be the need to copy/transfer information among Matlab, Mathematica, and Microsoft-based applications, from Office 2003 to the above-mentioned ones. Do you support these, and how complete is your product line for 64-bit CentOS 5? Based on your answer, I'll know whether to go with a virtual machine-based solution, which means a Windows VM, or can remain Linux-only, with your solution. Thank you very much.

I got this working perfectly at home - what should be exact same setups- - Fresh install of CentOS 5 32-bit from DVD - yum update & upgrade - Reboot - yum install mysql-server - Download phpmyadmin and bugzilla from their respective home pages - Move both to /var/www/html, naming the extracted phpmyadmin directory as phpmyadmin, the same with bugzilla - Copy my working httpd.conf file from home and replacing the work one, then restarting httpd - sudo /etc/init.d/httpd restart - Verify mysql is running - sudo /etc/init.d/mysqld restart Call up firefox via an ssh x session and visit http://localhost/phpmyadmin/index.php. Instead of showing a rendered page, it only shows the text of the index.php file. Same for http://localhost/bugzilla/index.cgi What did I miss? The same config file from home, in a setup that worked perfectly, is missing something here! /usr/sbin/httpd -v Server version: Apache/2.2.3 Thanks for any help. Scott

Kickstart install via network, nonexistant disk sda
by ethan＠757.org 27 Nov '07

27 Nov '07

Hello all, I have 3 Supermicro 1u servers, each with dual 250gb SATA drives. I have a server with CentOS 5 64bit setup for pxebooting and kickstart installs. I have a kickstart install file that doesn't specify the disks specifically. It works like a champ, and the operating system installs and completes. I have a kickstart install file that specifies the disk devices (sda, sdb) pulled and modified from another similiar system. My goal here is configuring software RAID. Whenever I try to use the file for software raid, she dies with an error: "Specified nonexistant disk sda in clearpart command" ... if I removed the --drives-sda,sdb from the clearpart, it will just fail on the part command for RAID. Now, I struggled with machine #1 for a long time, then realized that it is probably the onboard raid in the BIOS, which isn't a real RAID. Turned it off, and it appeared to be the solution. I thought I was well on my way. I did the same for machines #2 and #3 which had no installation attempts, and they would not work. I can take the disks from machine #1, which will run through a reinstall fine, and throw them in machine #2 and *it will install*. So it seems to be an issue with the partition information on the disk. I tried doing a dd if=/dev/zero of=/dev/sda (bs=1024 count=10000) to try to overwrite any RAID metadata and partition information and what not. During the install, when I have the error that sda is invalid, I can hit the vty2 (emergency shell) and easily run fdisk /dev/sda and print the partition table. So the device is there, and accessable. I've tried every incarnation of clearpart commands. My current kickstart info: # RAID kickstart # clearpart --linux --drives=sda,sdb # clearpart --all --linux --initlabel clearpart --drives=sda,sdb --all --initlabel # clearpart --all --initlabel --drives=sda,sdb part raid.9 --size=100 --ondrive=sda part raid.10 --size=100 --ondrive=sdb part raid.13 --size=2000 --ondrive=sdb part raid.12 --size=2000 --ondrive=sda part raid.16 --size=100 --grow --ondrive=sdb part raid.15 --size=100 --grow --ondrive=sda raid /boot --fstype ext3 --level=RAID1 --device=md0 raid.9 raid.10 raid swap --fstype swap --level=RAID1 --device=md1 raid.12 raid.13 raid / --fstype ext3 --level=RAID1 --device=md2 raid.15 raid.16 Any advice is appreciated!

Re: SOLVED: Re: [CentOS] Dual boot box: WinXP & CentOS 5: Impossible to restore WinXP?
by Lanny Marcus 26 Nov '07

26 Nov '07

Some thoughts, for anyone faced with this type of problem on a dual boot box in the future: My first thought was to try to Rescue the WinXP Spanish language installation that came on the Dell Dimension 2400, out of the Dell factory. Later, I decided to wipe the entire drive, since I now have a WinXP English language Restore CD and I wanted to redo CentOS5, so I would have room to experiment with VMware Server. With regard to restoration or rescue of WinXP on a dual boot box, I believe the method Ross explained last week, about doing it from CentOS5, would be the fastest and easiest. For those with boxes dedicated 100% to WinXP, I believe the Ultimate Boot CD for Windows, which Phil mentioned (based on the BartPE Live CD) is the way to go. I downloaded the 196.6 MB file from http://www.ubcd4win.com and I have copied the contents of the Dell WinXP Restore CD to my HD. I like the fact that they explain workarounds, for those using a Dell WinXP Restore CD to make the UBCD4WIN CD. One of the mistakes I made, was after I got the box in 2005. On other new systems, I've wiped the drive and done clean installs, with four (4) partitions for Windows. Had I done that in 2005, I would have known that the Drivers for the box are not on the Dell WinXP Restore CD or on the Dell Driver CD that came with the box. Fortunately, last week, after I mounted the NTFS partition read only, I not only copied my data onto CD's, I copied other files, which turned out to include the Driver for the NIC. I believe the audio and video Drivers are also on the CD I made last week. :-) I went ahead and wiped the drives on the boxes of my wife and daughter, since they were out of town. The installation on my wife's box (Compaq Evo D300v) was the easiest. All of the Drivers for the Compaq Evo were on the Dell Restore CD, with the exception of the Driver for an inexpensive store brand web cam we bought recently. I will need to buy OEM license's for that box and daughters box. More $ for Microsoft.... All of the Drivers for my daughters box (Dell Dimension 4300) were on the Dell WinXP Restore CD too. I've configured wife and daughter as Restricted Users in WinXP, as Ross suggested. Special thanks, to everyone who responded with ideas! Lanny

Linux driver for HP Laserjet 3500 printer - yum won't install
by Andrew Allen 26 Nov '07

26 Nov '07

I'm trying to install the linux driver for an HP Colour Laserjet 3500 in CentOS 5. I've installed the kde.repo (with appropriate priorities set up), but when I try yum install pxljr-1.1-1.i386.rpm, yum says 'nothing to do' - is this because the priority protection won't let it install from the kde repo? The alternative approach seems to be to use yum localinstall with the downloaded package, but then I get the message that 'the package is not signed'. So how do I resolve that please - the instructions regarding 'signing of packages' don't seem very clear to those of us who weren't 'born and bred' on linux! Thanks, Andy

Partioning Error: Dual Boot, WinXP & CentOS5, 27 GB Free space; my error is?
by Lanny Marcus 25 Nov '07

25 Nov '07

Hello: Starting Friday afternoon, I blew away the installations on the three (3) boxes we use as Desktops. On two (2) of them (my Dell Dimension 2400 and my wife's Compaq Evo D300v), I have MS Windows XP and CentOS5 running. :-) On my daughters box (Dell Dimension 4300) I am having problems with the partitioning. Probably this is due to some mistake I have made, with regard to "Active" or "Primary" partitions? The HD has four (4) NTFS partitions on dev/hda. hda1 > hda4. According to the partition table shown in the CentOS5 installation, there is 27925 MB of Free Space on the HD. If I try to create a /boot partition (100 MB) or an LVM, I get: "Error partitioning - Could not allocate requested partitions. Partitioning failed. Could not allocate partitions as primary partitions. Not enough space left to create partition for /boot More or less the same error: "Automatic partitioning errors - You have not defined a root (/) partition. This can happen if not enough space." What am I doing wrong on that box? TIA! - Lanny --------------------------------------------------------- Over 800 Magazine titles up to 85% off http://lowcostmagazines.com/

snapshots of server state with F/OSS software

I'm looking for something (ideally) in the CentOS repo that lets me easily take and restore snapshots of my system while powered on (similar to how later versions of Norton Ghost work). Is LVM my best bet to do this? (I hate to admit this, but up to this point when I've been in a pinch, I've just powered the box down on off hours and then imaged it via some sort of live cd)

stuck process continues under strace
by Jure Pečar 24 Nov '07

24 Nov '07

Hello, I have a few VPSes with centos5 on which I expirience a strange phenomen: Every now and then a random network communicating process (lynx, sendmail, httpd, ...) starts eating 100% of cpu while doing nothing. That slows down a VPS a lot. When examined with lsof, all of such processes have at least one tcp connection in close_wait state. Touching such process with strace -p makes it spring back to life and it goes on working normaly. Sendmail straces are specialy interesting, because I can see it wants to continue smtp dialogue somewhere from the middle. I suspect the cpu usage I see is the process trying to read from tcp socket to which the other end has nothing more to write. But as this is not happening in userspace (where I would see recv() in strace output), I expect the problem lies higher, in virtuozzo. I would like to be able to understand what is going on and maybe be able to reproduce the problem, but I don't have enough understanding of what exactly goes on. Specifically, what does strace do to a process that knocks it out of the cpu consuming loop? I'd be happy if you can give me some pointers. -- Jure Pečar http://jure.pecar.org/
