Where is perl-spamassassin for Centos 5?
by Robert Moskowitz 15 Aug '07

15 Aug '07

I am looking for it..... I need it (according to the docs) for Scalix 11. And their docs say it is included in SuSE, but it does not seem to be in Centos 5. And I think I had it for a Centos 4 system.

Cent OS 5 server setup walkthrough
by Rohit Rai 15 Aug '07

15 Aug '07

I have just finished setting up and configuring a server running CentOS 5 with 2 Xen VMs. This article describes my journey through this, including the problems I faced and there solutions. It documents the installation of CentOS 5, from a single CD, adding software, configuring squid, NFS, Xen, etc and sharing yum cache and lot more! I request everyone to check this out and tell me what should I do to make this setup properly secured and robust. Comments requested!!! It will definitely help you if you are a newbie and want to set up a CentOS server. mytechrantings: Setting up a Cent OS 5 server<http://mytechrantings.blogspot.com/2007/08/centos-5-selinux-xen-squid-yum-c…> -- I am careful not to confuse excellence with perfection.

chown and chgrp on 4.5 vs 5.0
by Jerry Geis 15 Aug '07

15 Aug '07

I just noticed that on centso 4.5 I have an executable with the +s (chmod +s myexe) doing a chmod root myexe and chown root myexe does NOT affect the +s setting. However, on centos 5 this is not the case. chmod +s myexe chown root myexe or chgrp root myexe will DROP the +s status. How can I get around this? I want to keep the owner, group, world settings. Thanks, Jerry

SFTP error (perhaps due not to using passive mode?)
by Rogelio Bastardo 15 Aug '07

15 Aug '07

I'm getting a weird error when I try to sFTP on a CentOS box (which I don't have root access). when I run: sftp -oPort=990 user(a)host.domain.com I get the following error, which I suspect is a result of not being in "passive mode" (which works when I use Filezilla on Windows) Connecting to host.domain.com ssh_exchange_identification: Connection closed by remote host Couldn't read packet: Connection reset by peer Any suggestions?

ssh key with redundant targets?
by Les Mikesell 15 Aug '07

15 Aug '07

Is there a way to tell ssh that it is OK that the target of a command may be one of several machines, not necessarily the one it stuck in ~/.ssh/known_hosts last time around? This might be due to DNS round-robin or an HA failover. Setting StrictHostKeyChecking to no in /etc/ssh/ssh_config allows commands to complete but it still prints the warning which confuses people. -- Les Mikesell lesmikesell(a)gmail.com

Re: [CentOS] Forcing ifcfg-eth0 to use the same nic in multi nic machine

I believe that as long as the interfaces are connected to different networks, there is no problem having the same MAC address. Connecting two NICs with the same mac address to the same network would be a Bad Thing (tm), as network switches would be confused about where to send packets destined for the MAC address in question. Years ago, Sun workstations with multiple NICs would always have the same MAC address for all the NICs. That being said, it does seem less than helpful on a modern motherboard. I just wanted to point out that it _may_ be an intentional design issue (though I agree a bad one). Cheers, Dave Thompson UW-Madison

Re: [CentOS] Forcing ifcfg-eth0 to use the same nic in multi nic machine
by Les Bell 15 Aug '07

15 Aug '07

Sorry - I missed the original post - but I can think of one scenario where two NICs have the same MAC address. However, it's extremely unusua.l. The IEEE has managed the allocation of addresses for Ethernet, but IBM has done the same for Token Ring. The two didn't talk, and so their allocated address ranges overlap. Consequently there are a number of pairs of Token Ring and Ethernet cards out there that have the same MAC address. Token Ring/Ethernet bridges have to do some bit-fiddling to map TR MAC's to Ethernet because of it. That's probably not what the OP was enquiring about - unless he's extremely unfortunate and still has to deal with TR.

NFS / DNS problem
by Simone 15 Aug '07

15 Aug '07

Hi all, Today we have had a strange problem that has taken down our website, we understand what happened but not why so I am hoping someone has seen this before. We have our web servers (web1 web2 web3 ..... web10) mounting an NFS share (/export/data) from server nfs1. On the web server side we use autofs in the format nfs-dedicated:/export/data where nfs-dedicated is an alias in our internal DNS servers pointing to server nfs1. We run a primary and a secondary DNS (bind) server ns0, ns1 authoritative for our zones and our webservers have them configured in /etc/resolv.conf Today we had to run some upgrade on the dns servers (bios firmwares etc) so we took down ns0 and with it our website went down. All the nfs shares disappeared from the web servers (the logs show requests to mount/unmount timing out), but at the same time on nfs1 the logs show requests (mount and unmount) coming from the web servers and no errors. As soon as ns0 is back up, all gets back to normal. Minutes later we take down ns1 for maintenance and it doesn't have any impact on the website. dig @ns0 nfs-web gives exactly the same results on ns0/1 Back to the office we try to reproduce the same scenario configuring iptables on web3 to block traffic to ns0 but the server (web3) keeps working fine reverting to ns1 for name resolution (as you would expect). Has anybody seen this happening before? Any comment/suggestion much appreciated. Thanks Simone

text installer used in Linux?
by Rogelio Bastardo 15 Aug '07

15 Aug '07

Can someone tell me the name of the text installer used in distros like Debian / Ubuntu? I'd like to create one upon first time boot for a CentOS-based virtual application I'm making. So, after someone boots up, I'd like to have a little GUI thing ask them questions and then put those variables in a file (or maybe use something like sed to edit other network config files).

Forcing ifcfg-eth0 to use the same nic in multi nic machine
by Doug Coats 14 Aug '07

14 Aug '07

I am new to CentOS (coming from Fedora) and I really like it! I am having difficulty getting one of my machines to boot and assign the same designation of eth0 and eth1 to the same nics consistantly. I have an MSI motherboard with 2 nics on the board. Strangely enough both nics report the same MAC address. This is not an issue since I use the computer to route between two different subnets so they don't see each other on the network. The problem comes when I reboot and they race against each other to see which one will get to be eth0. If they switch my routing dies and I loose access with out rebooting and hoping they switch back or switching the actual cables. I have googled and searched my networking resources but all of the fixes that I have found focus on using the MAC address to solve the problem but in my case they are the same. The only difference is that they use different drivers. One is a Realtek and other is a Marvell. I have turned off Kudzu or they reconfigured every time a booted the machine. It only happens every once in a while but I need it to be consistent. Any suggestions or pushes in the right direction would be most appreciated. Doug Coats

Using a program
by Ioannis Vranos 14 Aug '07

14 Aug '07

OS: CentOS 5 x86. There is a program I am using which requires a start up service running. The service runs in Runlevels 3,4,5. When I am using the program as a root it works fine. When I am using it as a user it produces an error. If I do as a root, /etc/init.d/program start, then I can use it as a simple user. I have emailed the company that makes it and had no response. Any idea on how to fix this?

hw raid 10 with 4 disc, recomended partitiontable
by kai 14 Aug '07

14 Aug '07

I am familiar with centos and this forum, and have some rhel / centos questions. Therefore I'm asking the question here I am about to install rhel4.5 on a hp dl380 with 4 disc's. The standard rhel installation installers all in one partition? Will there be any advantage of splitting the file system up? What would be a good recommended partition table for a server running scripts handling big amount of transactions? Normally i would do something like this, but i need to ask the question since I haven't installed on a production machine before /boot /opt /usr /var /tmp /home An other thing, I haven't installed rhel before, only centos and notice a difference in that yum is not a part of rhel, and later figuring out that no updates are possible since I installed without the graphics's. Are there other significant differences between CentOS and RHEL?

Possibly someone who knows a *lot* more about DNS management than I do can look at his DNS management? I have the ttl (IN) for "A" and "PTR" at 3600s for my web site. Faster, if one changes IP address. He has those ttl at 100000s. Possibly he could use the IP address more, in DNS management?

Matlab 2007a and C5 out-of-box broken
by Scott Ehrlich 14 Aug '07

14 Aug '07

I had to reinstall C5 64-bit out-of-box on two machines. Before the reinstall, Matlab 2007a 64-bit worked fine. Now, I get "failed to start the desktop; failure loading desktop class". matlab -nojvm works fine. The reinstall was not an upgrade. I tested on two identical systems - one before I installed the NVIDIA drivers, and one after. No difference. I installed jre and jdk 1_5.0.11 on one system, and redirected /usr/bin/java to the newer one. No luck. I tried installing Matlab as root and sudo, running it as root and plain user. No difference. Web sites aren't helping me much. I performed a complete install (selecting ALL items from EVERY catagory of the C5 64-bit DVD). The machines are not on any network and never will be (both isolated systems) Anyone else with ideas? Thanks. Scott

I just had occasion to do a fresh install of CentOS 5 on my IBM/Lenovo T42p laptop today (had been upgraded from C4 to C5beta to C5 for testing/QA purposes and was a bit of a mess), so I just went through configuring the IPW2200 from scratch. There is no /usr/share/system-config-network/netconfpkg/gui/network.xpm on my system, but I do not see any errors starting system-config-network from the command line.

Also, it seems to have configured eth1 as an ethernet > device whereas I want it to be a wireless device. So I'm absolutely baffled > and don't know where to go from here - I may just have to stick with > Windows XP for my wireless connection. I simply loaded ipw2200-firmware-3.0-3.nodist.rf from RPMforge, added "alias eth1 ipw2200" to /etc/modprobe.conf, rebooted, and the device showed up as eth1/Wireless in system-config-network (both the Devices and Hardware tabs). Listed as "Intel Corporation PRO/Wireless 2915ABG Network Connection" on the Hardware tab. (Comments about needing dkms in an earlier reply were off-base. That was apparently cobwebs from C4 days.) If the IPW2200 is showing up as Ethernet rather than Wireless it is incorrect. You may have leftovers from earlier attempts to install from tarballs. Given that and the other system-level problems noted above, I'd try a fresh install before going to the Redmond OS. Only took about 2 hours here from booting for a network install through a fully-updated and configured Workstation/Development install with additional 3rd-party packages (including Octave from EPEL, octave-forge, Acrobat Reader, Sun Java, Adobe Flash, VMware, and WiFi - cheating a bit - I had other working systems to draw configs from and pre-built local packages for acroread, octave-forge, and Java). Thanks Phil, I might just do a complete re-install of CentOS 5 when I return home from holiday in Spain tomorrow! This attempt to get wifi working has kept me occupied for the last 2 weeks or so (among other things). The problem is, I have to remember exactly what are the correct steps along the way so that I don't end up with the same problem(s)! Andy Sorry you're having such problems.

decTOP - Centos install fails but DSL frugal install worked
by Robert Moskowitz 13 Aug '07

13 Aug '07

I got 4 of those decTOPs (http://www.dataevolution.com/dectop%20info%202.htm) and upgraded the memory to 512Mb. I cannot get Centos 5.0 to install. I have the keyboard mouse attached to an ATEN USB-PS/2 adapter (probably should try without this). I have a USB DVD/CDRW drive. The install CD boots just fine. But then the install says, "No CD" and takes me to Askmethods. So I use FTP, as I typically do anyway. They have a generic USB ethernet dongle, but the last device listed on the ethernet devices seems to work just fine. I get all the way through configuring and when it gets to Resolving Dependencies, it crashes. Something about not finding the kernel? And how do I remotely write the debug information? FTP does not seem to be the protocol used. So I partitioned a drive on another system. In partition 4 I copied the 6 ISO CD images. I boot from CD, and then switch to Local Harddrive from /dev/hda4 and /. . Then install follows the same behaviour as the FTP install, so at least I know it is not the USB ethernet. And there is no option to write the dump to /dev/hda4 Openfiler 2.0 hangs at "Resolving Dependenies". Just sits there. Oh, Openfiler 'figured out' to load up a USB driver to get to the CD. I haven't found my FreeNAS CD to see what it does. But the latest D*#nSmallLinux (DSL) had no trouble booting and running of CD. Now I have successfully done the Frugal install to the hard drive and am booted without the CD at all. Now I REALLY want to run Centos on a couple of these units. What should I look for that is causing Centos to fail to instal? How do I capture that debug trace? Since I DO have DSL up and running, if there is some test to perform, let me know. I haved NO experience with DSL or Knoppix. Next is an ASTLinux install on one of the boxes. I really want Trixbox instead.....

Before I added that line to the /etc/fstab file in my daughters box, I did a "yum update autofs". No joy. Then, I added that line to the /etc/fstab file. No joy. Possibly, if I do some more research, I can figure out what to change your suggested line to. However, in my box, there is nothing like that in the /etc/fstab file and automount works perfectly. I would like to know what is putting this line into the /etc/mtab file in my box, when I have the CentOS DVD in the drive: /dev/hdc /media/CentOS_5.0_Final iso9660 ro,noexec,nosuid,nodev,uid=503 0 0 Whatever is causing that line to be added to /etc/mtab apparently makes the automount work properly.

PHP 4 on Centos 5
by Juan Nin 13 Aug '07

13 Aug '07

Hi! I want to install PHP 4 via RPM on a CentOS 5 server. I downloaded the CentOS 4.5 , installed all needed dependency packages, but I'm having troubles while building the RPM: I was having compile errors with the Apache APR module, I had to make a symlink form apr-config to apr-1-config, since the package expected to find apr-config which didn't exist, and had to pass via CFLAGS the result of "apr-config --cppflags --includes --cflags" Now I reach a stage, where some test are made, I to check fo some PHP bugs and it fails there... I removed the first bug giving probelsm to see what happened, and failed with another one, which it's really strange, bugs like the #23951 which was solved in June 2003... I don;t understand why is this happening.. :( Has anyone been able to compile a PHP 4 RPM on CentOS 5 or are there any available SRPMs out there already prepared for this? I've compiled PHP 4.4.7 from source downloaded form php.net with no problems, but I would like to install it via RPM, preferably by using the CentOS PHP 4 RPM. If there isn't, I will compile directly form source and not use RPM, but would prefer to do it via RPM if possible Thanks in advance, Juan PS: please, don't reply telling me to use PHP 5, I NEED to use PHP 4 on this case, will migrate to PHP 5 ASAP, but still can not do it yet :)

Rick, The reason i used top was because I noticed that mailscanner and smtpd were always on the list UNLESS the issue was occurring. I will try ps + grep next time as well.

Cannot Boot XServer

I am currently using Virtual PC 2007 to install/configure CentOS 4.5. I've got the O/S installed ok. However since running a yum update, I can no longer successfully complete an init 5 boot. Virtual PC gives an internal error 13 message. If I boot to init 3, I can reconfigure the /etc/X11/xorg.conf file and run 'startx' manually without any problems. If I then shutdown the Virtual PC and restart, it will not boot to init 5. Anyone seen this before and can offer any assistance?

Automount configuration problem
by Lanny Marcus 13 Aug '07

13 Aug '07

I have a simple automount configuration problem. I've done two similar, clean, Custom installations of CentOS 5.0, on two similar, but not identical boxes. On my box, automount is working perfectly. On my daughter's box, it's not working. If I put the FC6 DVD into the drive in my box, I can see the contents of the DVD, without any problem. If I cat /etc/mtab in my box, I see this line: /dev/hdc /media/FC_6\040i386\040DVD iso9660 ro,noexec,nosuid,nodev,uid=503 0 0 In System > Preferences > Removable Drives and Media, in both boxes, for Storage tab, the 3 top boxes have check marks. Mounted on /media. On my daughters box, nothing in /media. It's /dev/hdc. Question: What configuration file do I need to change, in her box? TIA! Lanny

Re: [CentOS] Can't get ipw2200 to work in CentOS 5 on Dell laptop
by andy.allen＠virgin.net 13 Aug '07

13 Aug '07

Thanks again Phil for all your help, It's now on the hardware tab OK and says ipw2200 eth1 ethernet configured! However, what I just don't understand (and sorry if I'm being dumb!) is why the "new" adapter just doesn't show up in the list of adapters on the devices tab as Intel Coporation PRO/Wireless 2200BG or some such. So the problem is when I try to set up eth1 with all the necessary wireless info (WEP key etc), I can't do it because I can't select the right adapter! I'm sure I'm nearly there, but this last "small step for man" is proving to be a bit of "a giant leap...."!

Sorry if I'm stating the obvious, but you do need to reboot after adding the line to /etc/modprobe.conf. Memory is hazy as I have not done this for quite a while, but I believe you also need to add the adapter in system-config-network with "New" on the "Devices" tab. It does have to show up on the "Hardware" tab for this to work. Assuming you get that far, it is good to create separate profiles to use when you move from wired to wireless. These can be selected at boot time by adding "netprofile="MyProfileName" (in my case MyProfileName can be "Wired", "WiFi", or a few other location-dependent values) to the kernel line in /boot/grub/grub.conf - otherwise defaults to the last used profile. Can either manually edit at boot time (requires you to remember the legal profile names) or maintain separate grub stanzas for different profiles.

yum install libstdc++-devel
by Tony Schreiner 10 Aug '07

10 Aug '07

On CentOS 4.5 (x86_64); happening on several different machines with libstdc++ and libstdc++-devel v. 3.4.6-8 only one of the i386 or x86_64 versions of libstc++-devel is installed if I yum install libstdc++-devel it will install the x86_64 version and remove the i386 version, but not warn me. Similarly if the i386 version is installed it will install the x86_64 and remove the i386, without warning. But if i remove libstc++-devel (and necessarily gcc-c++), then reinstall with yum install gcc-g++ libstdc++-devel both versions of libstdc++-devel will be installed.

inexpensive / reasonably priced workstation / server development box
by Robert - elists 10 Aug '07

10 Aug '07

We are testing some simple low bandwidth video and audio broadcasting using real server and client softwares. So, for quick check and simplicity, we were plunking along TESTING on an 3.2GHz XP box and I noticed frames were getting dropped on the broadcast just for resizing a window on the screen during the session. Talk about totally lame... I know this can be a big deal and start conflicting opinions yet I need some experienced perspective please? Can anyone chime in on what they use or what they would buy if they were going to have a workstation box for development that could double as test server and have good high speed storage and excellent video and audio etc etc Im thinking of a box that does audio and video development, can easily handle virtualization, and of course do general work apps plus setting up various server processes for testing whether intranet or internet etc etc It can be premade like specific dell or hp (please list component choices for clarity) OR A hand built box with specific list of components that Now, I know this has been done in magazines with great expense, and even with lower expense, yet I trust the list more than a magazine that wants to sell me advertising etc Thanks in advance - rh

Postfix smtp freezing
by Jason Ross 10 Aug '07

10 Aug '07

Hey all, For the last 8 months I have been running a postfix / mail scanner setup based on Johnny Hughes' excellent tutorial. For the firs 7 months I have had no issues. This past month I have been having instances where the user gets an smtp error while trying to send email. Restarting the postfix service is all it takes to resolve this issue. The problem is that it has begun to occur more and more often. It is now up to once every day. I have found nothing unusual in the mail or messages logs. As I am an ultra newbie I am unsure of the next step to take to resolve this. I have search through the past messages on this list and can find nothing. Anyone have any ideas? Thanks, Jason Ross

new CentOS 5 as DNS server
by Ray Leventhal 10 Aug '07

10 Aug '07

Hi folks, As a breather from the "thread-now-wider-than-my-headers-window-in-thunderbird" conversation re: mixing repos, I have a question regarding a machine I'm about to put online. :) I run a web hosting company and my secondary (primary to the world) DNS box died from a massive rootkit/hack last night. It was running an old Slackware 9.1 installation and I will be completely cleaning those drives sector-by-sector. After which I'll be installing CentOS 5 on that hardware. As it will be a production server and this is my first foray into CentOS/SELinux in a production environment I was hoping to get a recommended list of what to include and, more specifically, what *not* to include from the distro CDs I will be doing a text based install, hoping to avoid the installation of X. Other than BIND and vsftpd, I don't think I need much. This machine will be pulling zone files from my primary web server and storing some archive files and backups for me. I'm dilligently R`ingTFMs, and will continue to.... I'd sure be appreciative of any jumpstart help and/or any pitfalls of which to be cognizant. TIA, ~Ray

limits.conf for file size on vsftpd
by Eric Solomon 10 Aug '07

10 Aug '07

I've read conflicting reports on whether this works or not ... I have a chrooted instance of vsftpd (using chroot_local_user=YES), with nopriv_user=vsftpd. I set the following in my limits.conf file: vsftpd hard fsize 50000 Now, I know this works in a shell. However, I want it to work for users uploading files, but they can upload away without issue. Has anyone actually got the limits.conf setting to take effect? I tried adding session required pam_limits.so to pam.d/vsftpd, but that doesn't seem to have any effect either.

mysql.users deleting
by Jordi Espasa Clofent 09 Aug '07

09 Aug '07

Hello, Today I was working with MySQL in a test box (CentOS 5.0 x86_64) using phpMyAdmin interface. Accidentaly I've removed user table in mysql database (so, mysql.users)... :S I've two interesting questions: 1) Despite of it, ddbb server seems to work perfectly. I use 3/4 diferent databases with their mysql users... and it works yet! I don't understand, because mysql.users is the reference that MySQL server uses to admin their users and permissions access. ¿?¿?¿?¿?¿ Maybe a kind of memory caché is active... but I think this have not any sense... I've suposed the mysql.user was totally _required_. 2) ¿How I can reisert mysql.user table without reinstall entire package? I've got only a few mysql users only and I can recreate their permissions access in short time. -- Thanks, Jordi Espasa Clofent

Will this work? server+centOS5+100users?
by Ken Sedlacek 09 Aug '07

09 Aug '07

I am an experienced MS administrator of W2003 servers & Exchange systems. I have 5+ years UNIX mid-level experience but not in centOS. Grounded in SCO UNIX (the real SCO UNIX). We want to use CentOS on a recently grave yarded Dell poweredge 400SC server. This is a P4 3.0 Ghz, w/4GB memory, 2 SATA 250 GB disks. We want to use this server w/CentOS5, to provide file and print resources to 100 users. Each Department wants control over common folders of info for only their group. Each user wants control over their folders. Pretty much standard permissions for departments. Is this do-able with the server and centOS5 and 100 users? Thank you in advance. Ken

Centos 5 install failed. Could it be the USB ethernet?
by Robert Moskowitz 09 Aug '07

09 Aug '07

I am installing Centos on a decTOP via ftp, that comes with a generic USB ethernet. I chose the last listed driver some USB ethernet, and the install took off. Got all the way to selecting packages and then it failed. I don't have any SCP stuff to copy the debug too, but it LOOKS like the ftp is failing now. As if the installer lost track of the driver I selected? Well I will try a total CD install next. But any insight on this could be helpful!

CentOS 5.0 and php-yaz

Hi, I have a CentOS 5.0 LAMP server, and I need to install the php-yaz module to implement the Z39.50 protocol (which handles data exchange for public libraries). I've already done this with Debian (a one-liner: apt-get install php-yaz) and also on Slackware (more complicated: compile Yaz, rebuild PHP). Has anyone here ever done this on CentOS? What would be the most orthodox method to do this? Here's the Yaz page: http://www.indexdata.dk Cheers, Niki

Clone physical into virtual

Is there a formal, or preferred, method for importing a physical CentOS machine into a VMware instance? I know they make software to move Windows machines, but I couldn't find one to handle our CentOS servers. I have done something via scp/sftp in the past, which *seemed* to work, but if there's a better way I'm more than interested in hearing the process. Thanks! Scott

Opposite of cp -u
by Robert Moskowitz 08 Aug '07

08 Aug '07

I had at one point copied a large number of files between drives and did not use the -p and thus the timestamps were all set to the date of the copy. I did not catch this, and deleted the source. So I 'lived' with it and have since changed many files. Well, yesterday I found a good backup of many of those files and I want to restore them to their proper dates. cp -p -u is exactly the opposite of what I want. I want to copy only if the source files have an earlier date than the destination files. The source files are just an old copy on another drive that I found when cleaning up things...

Thanks Phil, I think I'll use RPMforge - the only thing is, I'm a bit confused about how I should install the rpm. Do I use yum - I think I have to modify something to get yum to access the right repository don't I? Or do I just download the appropriate rpm from RPMforge and install using rpm on the command line?

I have successfully used both the RPMforge and ATrpms packages for IPW2200 on my laptop. If you are using packages from either repo already, sticking with that one is probably the best bet. If using both or neither, depends on whether you want to go with Axel's (ATrpms) kmdl approach (may have to wait for him to build new packages after a new kernel arrives) or with Dag's (RPMforge) dkms approach (rebuilds kernel modules on-the-fly - requires development environment to be present). Either is likely to be less complicated than trying to use the tarball, and both have the advantage of having the package manager handle updates to new firmware or drivers.

RHEL5 and CentOS 5 root logins
by Scott Ehrlich 08 Aug '07

08 Aug '07

I found, under a 64-bit CentOS 5 workstation install, it is possible to modify /etc/inittab and add a couple of lines to prevent root from logging into the console. I found, under a 64-bit RHEL 5 server install, adding the same two lines completely breaks the OS, to the point that a reboot after the lines are added, the OS brings you to a fsck-like prompt, and other things break, too. I didn't have time to look at the logs for specifics, if any were recorded. Does anyone know if a CentOS 5 server install option permits locking out root from console login? Does anyone know of a way, in RHEL 5 Server edition, to prevent root from a console login? Thanks. Scott

Allocating 64 kbits/s out of 256 kbits/s for one LAN behind firewall
by Indunil Jayasooriya 08 Aug '07

08 Aug '07

Hi, I have a CENTOS BOX as a firewall . both iptabes and iproute 2 are running on it. pls see bleow for installed RPMs. [root@firebox ~]# rpm -qa |grep iptables iptables-1.2.11-3.1.RHEL4 [root@firebox ~]# rpm -qa |grep iproute iproute-2.6.9-3.EL4.7 It has 3 ethernet cards. pls see below. eth0 - internet ip (pls asume. 1.2.3.4/29 ). it connects to ISP router. eth1 - 192.168.100.254 eth2 - 192.168.101.254 There are 2 LANs behind this firewall. both LANs have access to internet due to SNAT rules in the firewall. I have given many SNAT rules per ip basic. some users have full access, some have only web and smtp. I have added many forward rules to suit those SNAT rules. All work fine. one LAN is 192.168.100.0/24, while the other LAN is 192.168.101.0/24 Now, I want LAN with 192.168.101.0/24 to allocate 64 kbit out of 256 kbit. the rest for others. I added rules to the firewall. But I still can not allocate 64 kbit for LAN with 192.168.101.0/24 I think I need a PREROUTING chain for LAN with 192.168.101.0/24 Script is given below. INTERFAZ_INT=eth0 FULLBANDWIDTH=256 BANDWIDTH4LAN=64 iptables -t mangle -A PREROUTING -s 192.168.101.0/24<http://192.168.102.0/24>-j MARK --set-mark 0x5 tc qdisc add dev $INTERFAZ_INT root handle 1 htb r2q 4 tc class add dev $INTERFAZ_INT parent 1: classid 1:2 htb rate "$FULLBANDWIDTH"Kbit tc class add dev $INTERFAZ_INT parent 1: classid 1:5 htb rate "$BANDWIDTH4LAN"Kbit tc qdisc add dev $INTERFAZ_INT parent 1:5 handle 5 sfq perturb 10 tc filter add dev $INTERFAZ_INT protocol ip parent 1: pref 1 handle 5 fw classid 1:5 Still no luck. after applying the obove rules, I downloaded an centos ISO image. But , I still can download @ the usual rate. ( i.e 30-33 kbytes per seconds). If these rules work, I will be able to download @ about 8 kbyes per second. (i.e - 8*8 kbit= 64 kbit) That is what I expect ? Where have I gone wrong? -- Thank you Indunil Jayasooriya

CentOS5 pam_mkhomedir
by Peter Huber 08 Aug '07

08 Aug '07

I have a problem creating homedirs on the fly. Since RHEL5 / CentOS5 you have to use pam_oddjob_mkhomedir instead of pam_mkhomedir. Everything is working (the homedir is created) but two things. First on every logon I get the following error message, and I don't know how to fix it: org.freedesktop.DBus.Error.ServiceUnknown: The name com.redhat.oddjob was not provided by any .service files Second: The permissions of the new created homedir is wrong. It should be 700 but it is 755. Can anybody tell me, how to fix these two problems? Thanks Peter

Virtualisation of Netware?
by Nigel Kendrick 08 Aug '07

08 Aug '07

Hi, I am hoping someone can kick me up the learning curve (!) on Virtualization: We have an old piece of data logging software that was written in Turbo Pascal 6 using a file I/O module tuned to Netware and so it expects its data files to be on a Netware server and will not access them locally or via an MS/Samba share - essentially, it uses direct NCP calls for parts of its data access. The logging software was replaced two years ago, but we need occasional access to the data for a minimum of 6 years and so I wondered whether I could virtualize a Netware 3.x/4.x/5.x or 6./x server under Linux (or Win..er..you know..). I have found some articles on Netware 6.5 virtualization but would really appreciate input from anyone actually doing this already - otherwise I'll just have to keep the existing Netware server in the computer room to be fired up about 3-4 times a year 'on demand'. For info, I'm running a Netware 6.5 1-user 'demo' licence - the original install was on Netware 3.12 until the server died and no-one could find the original Netware floppies! Thanks Nigel Kendrick

startup config scripts for CentOS
by Rogelio Bastardo 08 Aug '07

08 Aug '07

On CentOS-based VM appliance I'm building, I would like to create a script that runs upon login that asks the user a series of questions that does (among other things) ask them to input their networking information (IP, mask, gate, DNS, etc). I'm hoping you guys might point me in the right direction. Here are some of the specific things I'm looking to accomplish with such a script. (1) Where might I look to for creating these types of scripts (e.g. I'm assuming Bash is the way to go here?) (2) Are there any templates out there that I might use as a starting place? (3) Once I write something, where/how do I call it in /etc/rc.d/ (4) And once it starts, what is the best way to make sure that it doesn't run again upon the second (and subsequent) reboots? Ideally, someone could show me a model of something like this that's already done, and I could just mod that. Otherwise, I'll grind through something manually, if I so have to....

"near native" performance with xen?
by Johnn Tan 07 Aug '07

07 Aug '07

Just wondering if there was a howto or other URL that explains what is needed to achieve "near native" performance on a xen domU -- for this purpose, I am thinking about a single domU running on a physical server, in comparison to that same physical server running the same kernel but non-xenified. For instance, using a physical partition for VBD v. using a file-backed one is one of the more obvious ones. Assigning all the VCPUs. And as much RAM as you can get away with (maybe leaving the dom0 with 512MB). But are there others? Since I'm doing paravirtualization, I assume I don't need to turn on VT in the BIOS? What about 32-bit v. 64-bit OS, for the dom0 and for the domU? (I'll be using CentOS-5.) Anything else? johnn

Yum install preferred arch only
by Ross S. W. Walker 07 Aug '07

07 Aug '07

I have a couple 64-bit CentOS 5 installations here and was wondering if there was a yum option to have it install only x86_64 arch by default if no arch is specified. I tired of having to append .x86_64 on all package names I only want the x86_64 versions of, if I want the i386 versions too I would add the .i386 package to the list... Thanks All, Ross S. W.

I did the same (changed the speed in the BIOS settings) and it's working. I tried it at 80 but I think I'm going to bump it to 160 and see if it works. I still wish I could figure out why the adaptec kernel driver won't install though. Maybe I'll try downloading the source and manually compiling the kernel module.

CENTOS 4 and mono
by Jaime Ventura 07 Aug '07

07 Aug '07

Hello, Im trying to configure my centos machine to run webservices. Im using the mono repo from www.*mono*-project.com, for rhel-4. After configuring every thing, it all seemed to work fine with a simple webservice for testing purposes. For that, a friendo of mine created a vb webservice on a windows machine and I copied the all resulting files(asmx, dll, etc). When I access the webservice via GET, every thing works just fine. But when I do a POST, the mod-mono-server2.exe goes away :( Does anyone can help me to debug the problem? The apache logs doesnt help much. Thanks
