Latest BackupPC release in CentOS testing repo
by Max Hetrick 11 Aug '10

11 Aug '10

BackupPC released 3.2.0 as a stable version a few weeks ago. The most current release is 3.1.0 in the testing repository. Are there any plans that this will be updated to 3.2.0 in the repo some time down the road? Also, will the BackupPC package be moved out of testing and into extras ever? Or are there reasons behind this that are more complicated, making it not "stable" to be in extras? I've been running the 3.1.0 RPM for a long time with no issues. Just curious. Thanks! Max

sshd bug?
by Matt Keating 11 Aug '10

11 Aug '10

Hi, I've found a bug/problem with my centos 5.5 server. Any users who have a password of 9 characters or more, only the first 9 characters are used by the OS... eg. i set my password to "123456789" and i try logon via ssh with password "123456789ofgjdfuh" - it lets me in. and if i set my password to "qwertasdfGHJB" and i enter "qwertasdfSDWQWSDS" - it lets me in... The 'passwd' command only recognises the first 9 characters too... Has anyone seen this before, or know how to fix it? I feel its a major security risk and would like it fixed ASAP. Thanks, Matt

Re: [CentOS] Iptables questions
by Bob Hoffman 11 Aug '10

11 Aug '10

Forgive me if this does not go with the right topic, I am on digest and responding to a topic sometimes makes it start a new one. My reason for the iptables questions is to not follow the practice of putting up a wall and ignoring hackers. I want to be more proactive. If I have set my ssh port to 55994 and am not using port 22, but hackers are pounding on my port 22 looking for Ssh, then I want to not only know about it, I want to log them and prevent them access to my server and web applications. At least temporarily. I see now that many of the programs are log users and not real time. And many like fail2ban actually add chains to iptables that I Could do myself. It looks like getting some books on netfilter may be the way to go. I would rather stop stuff at the firewall then trust apache, php, sendmail, vsftp, etc. I would rather use them as back up failsafes while I work on hack proofing the single point of entry. I have a server sitting right on the net and the constant barrage of 100s of Ips trying thousands of times at port 22 is insane. I examine my logs and see so much in the way of dns posion attacks, ssh-mail-ftp, etc attacks that I do not want to just sit back and Think I am fine because I have a firewall and centos will send me bug fixes. That firewall seems like the 100% way of going at stopping and preventing issues. If an IP is doing something it should not be doing, most likely you do not want it probing anything else either. That's why I ask.

Iptables questions
by Bob Hoffman 11 Aug '10

11 Aug '10

Hello, I have read and seen many options for additions to Iptables as a firewall and security system. All seem to react to logs and not to incoming packets (as far as I have seen) I am interested in doing a number of security ideas to the firewall, iptables, on my webserver. If you have a program you would suggest or believe iptables is the proper solution, please feel free to post that. Here are some of the things I would like to do 1) I have switched my SSH to a different port. I would like to still check for anyone trying to hit the old port 22 and log them. At the same time add them to a reject/ban for a certain period of time, lets say 1 day. 2) there are certain apache hacks (like things that include ../) that I would prefer to stop at the firewall. I would also like to log these attempts and begin a reject/ban for a certain period of time. Or just log until I figure out the best way to safely ban. 3) There are common script kiddie hacks that look for certain files 1 million times a day. I would like to either look for them in the incoming packets, log, and ban. Or I would like to be able to use my own php program to route them out and then add to a ban list that iptables can use. These are just some of the things I am looking at doing. I also want to start a ban list for mail packets too, why bog down sendmail when I know what they are? I realize some things might be done via programs like fail2ban (like my php program making a list) but others would be better at the firewall as active reaction security measures. Any input kindly accepted. Thank you for any help or ideas. Bob

CentOS 5, gnome-screensaver and password amnesia?
by Scott Ehrlich 11 Aug '10

11 Aug '10

I've built some CentOS 5.5 64-bit systems straight off the DVD, full installs, and the Gnome screen lock (manually invoked or automatically via the gnome-screensaver) does not allow the user to unlock the screen. The only fix appears to be ctrl-alt-F<1 - 5> then have the user log into the tty session, type pkill -f gnome-screensaver, log out, then ctrl-alt-f7 to return to X. These systems are standalone, so there is no option to remote in, and the display is never unplugged from the system as some of the RedHat bugzilla reports show. I did try a yum update but the problem persists, so I suspect the issue has not been fixed, or if it has, has not been released via the yum default locations. The screensaver and manual screenlock options must be enabled, so disabling them is not an option. I've also developed a cron job to restart gnome-screensaver every few minutes. I've got other systems, built back when CentOS 5.0 was out, that do not experience this problem. I've built newer systems with CentOS 5.4 and 5.5, yum updates, and I don't think they have experienced the problem either. I _think_ the issue, thus far, appears to be a full install of all packages from the DVD, which is how I build various standalones. Does anyone have an update on when this will officially be fixed? Thanks for any insights. Scott

KTorrent on CentOS 5.5 does not exist
by MGW-Discussions 11 Aug '10

11 Aug '10

Greetings guys. What repo do I need to install to be able to install ktorrent? I have CentOS 5.5 however, when attempting to download a distro for use on a virtual machine, which only seems to provide a torrent, I am unable to locate any torrent clients, and yum installation fails for ktorrent. I thought that ktorrent was associated with kde so why isn't it installed by default? Thanks. -- Respectfully, Martes G Wigglesworth M. G. Wigglesworth Holdings, LLC www.mgwigglesworth.com

Automounter problem in C5.5?
by Mark 10 Aug '10

10 Aug '10

Last night I was having some bizarre problems with my USB ports. I couldn't access one of my scanners, and when I started moving plugs around, it seemed as though I lost more peripherals. For some reason, I did NOT lose the laser printer, but my one scanner and my scan/fax/printer disappeared and wouldn't come back. I figured it might be the automounter, so I tried plugging in a USB flash drive, and it did not get mounted either. I rebooted and the problem disappeared (duh). Questions: 1) I'm suspected this was an automounter failure - is that the most likely culprit? 2) How do I restart the automounter when it dies, or can I? I've hit this issue before once or twice and only rebooting seems to make it right again. Thanks. Mark

Stuttering sound
by Eduardo Grosclaude 10 Aug '10

10 Aug '10

Dear List, After some googling around without any results, I'm quite puzzled. Since some past update I can't precise, kernel 2.6.164 works fine, however 2.6.194 has some sound problem in my somewhat old and beaten Toshiba laptop. -Audacious plays OK but other applications have problems. -For instance, mplayer acts quirky: when I pause a playing video, sound keeps stuttering endlessly. The same happens sometimes when I close mplayer window. -system-config-soundcard detects the card and starts to play sample but stuttering all the way, repeating every 4th of a second or so some 16 times, at about a 1/2 second rate. -Youtube has no sound! -Software volume control has been lost long ago, unrelated to this problem but interested in recovery anyway System is fully up to date. Any hints will be appreciated! Some relevant lines in my /etc/modprobe.conf as is now, with some scars left after unfruitful battles: alias snd-card-0 snd-hda-intel #options snd-card-0 index=0 #options snd-hda-intel index=0 remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel options snd-hda-intel model=auto options snd-hda-intel probe_mask=1 options snd cards_limit=8 getinfo.sh output: == BEGIN uname -rmi == 2.6.18-194.8.1.el5 i686 i386 == END uname -rmi == == BEGIN rpm -q centos-release == centos-release-5-5.el5.centos == END rpm -q centos-release == == BEGIN getenforce == Disabled == END getenforce == == BEGIN rpm -qa kernel\* | sort == kernel-2.6.18-164.15.1.el5 kernel-2.6.18-194.3.1.el5 kernel-2.6.18-194.8.1.el5 kernel-devel-2.6.18-164.15.1.el5 kernel-devel-2.6.18-194.3.1.el5 kernel-devel-2.6.18-194.8.1.el5 kernel-headers-2.6.18-194.8.1.el5 == END rpm -qa kernel\* | sort == == BEGIN lspci == 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Proces sor to DRAM Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root P ort (rev 03) 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Ex press Port 1 (rev 04) 00:1c.1 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Ex press Port 2 (rev 04) 00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #1 (rev 04) 00:1d.1 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #2 (rev 04) 00:1d.2 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #3 (rev 04) 00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #4 (rev 04) 00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B2 EHCI Controller (rev 04) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d4) 00:1f.0 ISA bridge: Intel Corporation 82801FBM (ICH6M) LPC Interface Bridge (rev 04) 00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 0 4) 01:00.0 VGA compatible controller: ATI Technologies Inc M24 [Radeon Mobility X60 0] 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8036 PCI-E Fast Et hernet Controller (rev 10) 06:04.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Ne twork Connection (rev 05) 06:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 06:06.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394 Host Controller 06:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD) 06:06.3 SD Host controller: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller == END lspci == == BEGIN lspci -n == 00:00.0 0600: 8086:2590 (rev 03) 00:01.0 0604: 8086:2591 (rev 03) 00:1b.0 0403: 8086:2668 (rev 04) 00:1c.0 0604: 8086:2660 (rev 04) 00:1c.1 0604: 8086:2662 (rev 04) 00:1d.0 0c03: 8086:2658 (rev 04) 00:1d.1 0c03: 8086:2659 (rev 04) 00:1d.2 0c03: 8086:265a (rev 04) 00:1d.3 0c03: 8086:265b (rev 04) 00:1d.7 0c03: 8086:265c (rev 04) 00:1e.0 0604: 8086:2448 (rev d4) 00:1f.0 0601: 8086:2641 (rev 04) 00:1f.2 0101: 8086:2653 (rev 04) 01:00.0 0300: 1002:5462 02:00.0 0200: 11ab:4351 (rev 10) 06:04.0 0280: 8086:4220 (rev 05) 06:06.0 0607: 104c:8039 06:06.1 0c00: 104c:803a 06:06.2 0180: 104c:803b 06:06.3 0805: 104c:803c == END lspci -n == -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

Xen machines fail to reboot
by Gabriel Ogunleye 10 Aug '10

10 Aug '10

Whenever I ask a xen machine on my centos boxes to reboot, they always just shutdown. I control the machines via virtual machine manager, and connect to them using an ssh tunnel, for example, ssh -X user@host and then run virt-manager . This surprises me, because it's only on my centos boxes this happens. How can I find out of this is already a known issue?

finding out the time of the second-to-last reboot

Hello all, I've got a CentOS box that became non-responsive today for some obscure reason and had to be rebooted.

Thanks for any and all tips. Boris.

Moving users from Debian-based distro to CentOS
by Dotan Cohen 09 Aug '10

09 Aug '10

I have a Debian machine with four users that I plan on migrating to CentOS. As per Debian habits the UIDs start with 1000. Is it enough to reuse the Debian /etc/shadow and /etc/passwd files over? Or will I need to configure some other things? I had considered just creating four new users starting from UID 500 then chown -R -ing the user's home directories, but I find that invasive and possibly error prone (maybe there are files that are not owned by them). All advice appreciated. Thanks. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com

Hello all, I have been tasked with "fixing" one of our CentOS boxes by somehow downgrading the libgcc and gcc packages to a specific version (Required by the Oracle Grid Control client).

Is there an elegant way to downgrade the currently installed libgcc & gcc packages? Thanks, Dan

fail2ban behavior
by Joseph L. Casale 09 Aug '10

09 Aug '10

I created a filter and verified it with fail2ban-regex against actual lines in my log and it works. During restarts of fail2ban, only some previous ip's get banned immediately whereas some need a reoccurrence despite the jail's config specification of maxretry and findtime suggesting the entries mandate blocking. I'd assume the behavior after a restart is noe way if it weren't for the seemingly random immediate notification of blocks being different? Anyone with experience using fail2ban know anything about this? Thanks, jlc

what people really mean when they say they're running "5.3"?
by Robert P. J. Day 09 Aug '10

09 Aug '10

more a terminology usage question than anything else, but in a couple of weeks, i'll be teaching the first of a few sessions on RHEL admin and, unsurprisingly, i'll be using centos (as i've done in the past). when i asked the organizer to identify the specific version of RHEL that was being used at the client site, i was told 5.3 so i can easily install 5.3 on the classroom machines, but i'm curious about something and i'll have my contact look into it: if people *initially* install 5.3, is it standard behaviour to still regularly upgrade as new releases come out? obviously, i have to ask my contact to verify what the client has been doing all this time but, in general, what's the normal behaviour for people running centos/rhel? and is there a way to examine an install to see how updated it's been since that original installation? i just don't want to teach off of 5.3, only to find out later that they've been keeping up to date and 5.5 would have been a more appropriate choice. thanks for any tips. rday -- ======================================================================== Robert P.

Or is there a way I can tell my CentOS box "these are here, > look you fool, use them!"? Well that's sort of what I do. If you have space to create a separate boot partition for GRUB, about 20MB should be plenty. You can create it as an ext3 logical partition, inside an extended partition. That should solve the GRUB Centos issue. You then need to reinstall GRUB to that separate boot partition, otherwise GRUB will still be looking to boot from the MBR of the first drive - if that's where it is now. You can install GRUB to separate boot partition by: Create the separate boot partition, and label it something like GrubBoot, using e2label /dev/sd?? GrubBoot. create the mountpoint; /mnt/GrubBoot ================================================================== ** AutoLinuxInstaller Fedora Installation I have created a seperate Grub boot logical partition, in the extended partition, called GrubBoot /dev/sda13. This enables me to do fresh Linux installations into /dev/sda1 and /dev/sda2, without destroying the GrubBoot partition. Here's a URL to my partition layout: http://i34.tinypic.com/r9nccz.jpg from grub-install man page: `--root-directory=DIR' Install GRUB images under the directory DIR instead of the root directory. This option is useful when you want to install GRUB into a separate partition or a removable disk. Here is an example in which you have a separate "boot" partition which is mounted on `/boot' (I use /mnt/GrubBoot): The installation of grub to the seperate partition was done by: First mount the GrubBoot partition with: mount -v -t ext3 -L GrubBoot /mnt/GrubBoot then grub-install --root-directory=/mnt/GrubBoot hd0 This was done with F12 as the active OS. Centos 5.5 and F12 will boot now from the GrubBoot partition. I noticed that re-installing GRUB from Centos 5.5 did not allow Fedora 12 to boot. But for some strange reason, when I re-installed GRUB from Fedora 12, this also allowed Centos 5.5 root partition to boot. Here is what my /mnt/GrubBoot/boot/grub/grub.conf file looks like. Note I've added some dummy entries at the end to distinguish where GRUB is booting from: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition.

CentOS 5.5 : Installing Sources where they are visible to system(VBOX driver install)
by MGW-Discussions 09 Aug '10

09 Aug '10

I have installed the source rpms on CentOS 5.5 due to virtualbox upgrade not functioning. (the old one that comes with centos works fine, however, I wanted to newer one.) Whenever I run the driver installation script it fails with an indication that it could not find the sources. How do I correct the issue with the system not seeing the installed source rpms? -- Respectfully, Martes G Wigglesworth M. G. Wigglesworth Holdings, LLC www.mgwigglesworth.com

When should LVM be used?
by Ron Blizzard 09 Aug '10

09 Aug '10

In my old computer I have a much bigger hard drive then in this one -- and I plan to hand that old computer down to one of my sons -- keeping his current drive from an even older computer. Currently the hard drive on my old computer has SuSE Linux, but that will go. I'll rebuild CentOS 5.5 on it, but I want to leave some free space for whatever comes up and also dual-boot Vector Linux. Which, at last, brings me to the question... Is there any reason to use LVM on a personal desktop install of CentOS? It seems to me, for my purposes, that LVM is just a pain in the neck -- although I've always just let CentOS set it up during the install in the past. I would like to be able to use parted to resize partitions when I want to, and also I'd like Vector Linux to be able to read and write data to the CentOS partition. Would I be missing something by not installing LVM, or is this mostly for server purposes anyhow? Thanks for any pointers. -- RonB -- Using CentOS 5.5

ext4?
by James Bensley 09 Aug '10

09 Aug '10

Listee's... I have a 5.5 box and I have formatted a partition as ext4 however I can't mount it, the mount command is telling me its an unknown file system type. fsck tells me the partition is a clean ext4 partition but I can't mount it. Some reasearch has lead me to believe the problem is that ext4 isn't enabled in the kernel by default in 5.5 (this was originally a 5.2 box that has been upgraded over time, its now on 2.6.18). I'm struggling to find some idiots steps to either get the kernel rebuilt or use the CentOSPlus repo's to get the ext4 module for the kernel etc....Can anyone point me at an idiots guide to make this work? -- Regards, James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

Encrypted remote backup?
by Michael A. Peters 08 Aug '10

08 Aug '10

Can anyone recommend a commercial off site remote backup service with a client (preferably FOSS) for CentOS 5, preferably that allows encryption of the data being backed up? Small scale, I'm primarily looking to just back up my mail folder on my server. I've been backing it up to local hd via rsync but that drive just died, I'd prefer to have it backed up to somewhere more stable than a home box and automated via cron (cli tools a must), but encryption is important, people are snoopy and I'm paranoid about that sort of stuff.

Remote nautilus, X display forwarding problem

yum-fastestmirror inconsistent exclude behavior
by Matt Arnilo S. Baluyos (Mailing Lists) 06 Aug '10

06 Aug '10

Hi guys, I'm trying to figure out something wherein excluded repositories for the yum-fastestmirror plugin are still being used by the system. To illustrate: [root@sales ~]# cat /etc/yum/pluginconf.d/fastestmirror.conf [main] enabled=1 verbose=0 socket_timeout=3 hostfilepath=/var/cache/yum/timedhosts.txt maxhostfileage=10 maxthreads=15 #exclude=.gov, facebook exclude=maulvi, .gov.ph, .vn (Note the name of mirrors that I am trying to exclude) However, when I run yum, this is what I get: [root@sales ~]# yum update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Excluding mirror: mirror.pscigrid.gov.ph Excluding mirror: mirror.viethosting.vn * addons: centos.maulvi.net Excluding mirror: mirror.pscigrid.gov.ph Excluding mirror: mirror.viethosting.vn * base: centos.maulvi.net Excluding mirror: mirror.pscigrid.gov.ph Excluding mirror: mirror.viethosting.vn * extras: centos.maulvi.net * rpmforge: fr2.rpmfind.net Excluding mirror: centos.maulvi.net * updates: mirror.viethosting.vn Setting up Update Process No Packages marked for Update [root@sales ~]# If you notice, centos.maulvi.net is still being used despite me putting it on the exclude list of the fastestmirror config. Also, the behavior does not seem to be consistent as on another repo (updates), the previously excluded mirror.viethosting.vn is used. Any pointers on what I could be doing wrong? or is this a bug? Thanks! Regards, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

access to file system through web browser
by Jobst Schmalenbach 06 Aug '10

06 Aug '10

Hi. I am trying to find "something" (php prefered) that I can stick onto a Centos apache server that would allow me to browse a selected file system by employees through a web-browser "explorer like" interface. I know I can do this through WinSCP (and have done so), but my problem is I have Linux, Windows and MAC clients and my knowledge of MAC's is rather limited. I can limit access to the (php) files to (ranges of) IP addresses, so security is reasonable ok and doing this through a web interface saves me time, too, as I only have to do this once, and security fixes is easy, too. Is there anything that would imitate a tree view like interface to browse a file system? Jobst -- "She said she loved my mind, though by most accounts I had already lost it."

who uses Lustre in production with virtual machines?
by Rudi Ahlers 05 Aug '10

05 Aug '10

I'm considering setting up a Lustre cluster system for our XEN virtual machines as shared storage, mainly for high availability on our XEN VPS servers. Does anyone use Lustre in a production environment? What is your opinions / experiences with it? One of the main reasons I'm looking at using Lustre is that we have a few older machines, of different specs that I want to use for storage purposes. i.e. I don't want to use proprietary, or matching hardware if I don't want to. Many of these machines are still in good standing and of good spec (3.2Ghz PIV + HT & 4GB RAM, Core2Duo + 4GB RAM, single XEON + 4GB RAM, dual core Atoms, etc) Will this work? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Manually mounting partitions in "linux rescue" mode
by Edward Diener 05 Aug '10

05 Aug '10

I boot from the installation DVD, with an already existing CentOS 5.5 system on my hard disks. I have separate boot, root, and home partitions. I have moved the boot partition and now I need to re-initialize grub from rescue mode. Attempting to use 'rescue mode" to automatically mount my system under /mnt/sysimage eventally fails with an error message, which essentially says 'mount error' and nothing else. I am then put at a command prompt as root. So now I decide to manually mount my partitions at /mnt/sysimage and then do a chroot to /mnt/sysimage. This succeeds and when I look at my files they are there. I now try 'grub' and the 'grub' shell comes up. I now attempt the 'grub' command: root (hd0,9) only to be met with: Error 21: Selected disk does not exist. I do not know what this means and how I can correct it. Does anybody know what is going on ? One thing I am concerned about is that when I booted from the DVD and was eventually put at the command prompt, I saw there were devices in the /dev subdirectory but after I did the chroot, there were no devices in the new root's /dev subdirectory although when I had previosuly booted into CentOS 5.5 on my hard disk off course they were there. The other thing I noticed is that after the 'chroot' the 'mount' command showed only my root partition mounted on /dev/sdb8 where it actually exists ( along with sysfs and proc which I mounted from the old root ). But despite this there are no subdirectories under the new root's /dev. I am just trying to re-initialize 'grub' so I can boot my CentOS 5.5 system again. There must be a way to successfully do this from the installation DVD. If somebody can give me the steps to manually mount my partitions and succeed it would be very much appreciated.

CentOS to RedHat and vice versa
by Kwan Lowe 05 Aug '10

05 Aug '10

Has anyone ever tried to mass replace installed RedHat RPMS with their equivalent CentOS versions or vice versa? I was thinking of generating a list of all packages and then running RPM or yum with a 'replace' option. The reason for doing this: Years ago I was tasked with building a RHEL4 system. Budgeting, time constraints, the lunar cycle, etc.., prevented the purchase of an equivalent development environment. So CentOS was used for the development/test system. It sufficed for several years. Now I need to make them as close to identical as possible which means registering the development system in RHN and making it "standard". I've seen posts that RHEL -> CentOS is at least possible. That is, take a RHEL system and get it to update via YUM and CentOS repositories. I have not seen the reverse, however.

Introduction and request for help with virtualization
by Kevin Chang 04 Aug '10

04 Aug '10

Good morning everyone. This is my first post to this list. I am very new to Linux so please bear with me. Also, English is not my first language so please excuse me if I am unclear. I am trying to install CentOS Linux operating system in a virtualization setup. I have already built four host machines with CentOS 5.5 and KVM virtualization. I can install fine if I do a manual installation. I am now trying to automate the process. To this goal, I have create multiple LVMs inside my new volume group. The name of the volume group is vmstorage_vg. The problem occurs when I try to run the installation. I found a script via google: #!/bin/sh virt-install \ -n calcnode01 \ -r 1024 \ -f /dev/vmstorage_vg/calcnode01 \ --cdrom=/software/iso/CentOS-5.5_x86_64-boot.iso \ --accelerate \ --vnc \ -x "ks=ftp://192.168.0.101/pub/ks/calcnode01.ks ip=192.168.0.101 netmask=255.255.255.0 dns=192.168.0.20 gateway=192.168.0.1 text console=ttyS0" When I start this script from the SSH terminal it starts but I cannot see anything being installed. I entered the virsh console and see the calcnode01 entry if I do a list. If I try to connect using virsh I do not see anything. The kickstart was created from the anaconda file created from the manual installation. I enabled the options to create the filesystems. I think the installation is waiting on some input but I cannot see any console. I have tried with and without the "console=ttyS0" option. Thank you everyone for your time.

Kerberized NFS4 w/AD 2008 R2
by James A. Peltier 04 Aug '10

04 Aug '10

Is anyone currently using CentOS 5.5 with 2008 R2 AD authentication and a fully Kerberized NFSv4? If so would you mind sharing your configuration with me? I have been able to successfully get it working with Windows 2003 as discussed earlier on the list http://lists.centos.org/pipermail/centos/2010-July/096374.html With the exception that I had to use dynamic UIDs on the machine since we don't have Services for UNIX installed. Instead of going with a long drawn out certification of Windows 2003 R2 w/SFU, we plan to target our deployment in line with our Windows 2008 R2 campus deployment. I have followed everything that I did with Windows 2003 to get it working but NFSv4 w/Kerberos doesn't seem to work with 2008 R2 at all. No matter what I try I consistently get WARNING: Client not found in Kerberos database while getting initial ticket for principle NFS/hostname@DOMAIN using keytab or ERROR: No credentials found for connection to server any help would be appreciated. I've been banging my head against a wall for a while now and may have damaged to many brain cells to see what's going wrong. -- James A.

force b/w printing
by Janez Kosmrlj 04 Aug '10

04 Aug '10

Has anyone an idea, how to force users to print b/w on a color printer. We are in the process to deploy color printers to some of our offices where they use centos 5.5 as their OS. They need the printers to print some advertisement material. But for everything else, they don't need it. And because of the costs of the color printing we would like to force them to use B/W where not explicitly necessary. Is there a way to force a printer driver to be just B/W even if it is a color printer. So i could install a second color printer which would only be available to a special print user.
