5.1 yum: distroverpkg=redhat-release ignored?
by Rainer Traut 04 Jan '08

04 Jan '08

Hi, is this the right behaviour of yum? yum.conf has: distroverpkg=redhat-release But yum obviously uses centos-release to find out the distro version. So is yum patched to do this? Thx Rainer

Random files in homedir gets deleted
by Christopher Thorjussen 04 Jan '08

04 Jan '08

On one of my systems I seem to loose a file or two from time to time. Last night, one of my files (/home/online/sh/NattjobbPrivat.sh) was deleted/removed/vanished. Another time it was /home/online/sh/daemon that was deleted. But I can't seem to find anything strange in the logs or in the history, nor would any of my scripts running in crontab mess with those files. Where can I look for clues? And how do I enable audit for file operations in my home folder? /Christopher Thorjussen

How to size an email server to handle 5 million emails per day
by Erick Perez 04 Jan '08

04 Jan '08

I have no idea as to how to size an email server. I was approached by a customer that wanted a single server with RAID 1 disks to handle about 5 million emails a day. In general terms, what parameters should I take into account to size the hardware specs when the average email is about 10kb, the smalles email is 2kb and the largest email is about 5meg (with attachment) thanks, -- ------------------------------------------------------------ Erick Perez

anyone care to point me in the right direction? LVS
by William Ottley 04 Jan '08

04 Jan '08

i'm trying to setup LVS, and tried both the lvs-dr and the lvs-nat, but can't get any to work. I'm hoping people here can answer a few questions that might help and shed light onto the situation? #1 with regards to the Real Servers, is there anything that needs to be configured other that the http service? I ask this, because I suspect yes, and it has to do with what type of LVS you have: 1a) lvs-dr: on the RIP of the web servers, create an lo:0 and assign the VIP to it 1b ) lvs-nat: on the RIP of the web servers, make sure the default gw points to the inside network card eth1 1b) lvs-nat: on the LVS, with 2 nics, eth1 (private where web servers are located): 192.168.0.100, and create a nat gateway of 192.168.0.254, where the real web servers gw is, and make it eth1:1 how do I go about getting diagnostic info from all this? pulse? i can't connect at all to any of the web servers.. If any has the time, i will glady send my configs.. Thanks! william -- --------------- Morpheus: After this, there is no turning back.

MyhtTV or Freevo or something else?
by Mindaugas 04 Jan '08

04 Jan '08

Hello, I have the idea brewing for some time in my mind - to build Linux based HTPC. It would be used for movies, cable (analog for now) recording, Stepmania, backup station, etc. And I would like to get some information before proceeding to estimate the cost. Which one of the Linux projects would you suggest and why? MythTV, Freevo or something else? Is CentOS good for such task or I should better use some more bleeding edge distribution like Fedora? Also what are hardware requirements? I believe HD 1080p h264 movie playback will set the bar. Which Intel or AMD CPU is enough (but not too expensive) for that? And which video card is more suitable for such task. HTPC would be connected to Panasonic LCD TV with VGA and HDMI inputs. Thanks, Mindaugas

[Semi-OT] Advice on large webmail setup
by Neil Thompson 03 Jan '08

03 Jan '08

Hi all, As the resident Linux guru, I've just been tasked with costing a webmail setup for about 600 000 users. They each have 10MiB (small, I know) mailboxes. The current setup has about 40 million web page accesses per month. Has anyone here any experience with this kind of thing? If so, any pointers as to software and hardware used, and any other advice would be appreciated. TIA -- Cheers! (Relax...have a homebrew) Neil THEOREM: VI is perfect. PROOF: VI in roman numerals is 6. The natural numbers < 6 which divide 6 are 1, 2, and 3. 1+2+3 = 6. So 6 is a perfect number. Therefore, VI is perfect. QED -- Arthur Tateishi

You can fail-over using iSCSI multi-pathing. Have the initiator log in to both targets and then setup dm-multipath to do fail-over.

The ticket clinic, What Is U.S. Copyright Law?
by Blogger Man 03 Jan '08

03 Jan '08

The ticket clinic, What Is U.S. Copyright Law? The US Copyright Law grants rights to individuals for the works they create. The US Copyright Act of 1790 has changed over the years. The current basis of US copyright law is based on the Copyright Act of 1976. US copyright law is relatively automatic. Once someone has an idea and produces it in tangible form, the creator is the copyright holder and has the authority to enforce his exclusivity to it. In other words, the person is the owner of the creation. It is not necessary that a person register their work. However, it is recommended and it can serve as evidence if someone ever violates a copyright. It is interesting to note that when an employer hires an employee to produce a work that the copyright is given to the employer. Violations of US Copyright Law are generally enforced in a civil court setting. However, there could also be criminal sanctions brought against someone who violates US copyright law. Someone in serious violation of US Copyright Law, such as counterfeiting, can find themselves on the inside of prison looking out. People need to understand the copyright symbol is not a requirement. Someone may have a copyright, yet their work may not have a copyright notice or symbol. US Copyright Law covers a wide range of things that are derived from artistic expression, intellectual or creative work. This includes things such as literary works, music, drawings, photographs, software, movies, choreographic works such as ballets and plays, poems, paintings and more. The law covers the form of expression, not the concept, facts or the actual idea of the work. This means that someone can use another person?s idea or concept and produce their own take on it. However, copying another person?s work is a violation. some things may not be copyrighted but they may be protected by a patent or trademark. Individuals who have a copyright on a particular piece of work can do with it what they will. They may choose to copy it and sell it. They may display their work or perform it in public and charge admission, or they can assign or sell the work to someone else. Individuals who have a copyright can also choose to do nothing with their work, if that is their desire. However, if someone comes along and takes the work and tries to use it in some way, that person is still in violation of the owner?s copyright. Copyrights cover published and unpublished work. Anyone who is in the creative arts arena should be very careful that they do not violate US Copyright Law. For that matter, anyone who is a fan of the creative arts should make sure they are not in violation of a copyright. Simple things like uploading, downloading and sharing music or movie files can result in serious charges and fines being brought against them. The popularity of the Internet and file sharing software has increased copyright violations. Copyright owners are starting to take a stand against copyright violators and are hunting down the perpetrators. Be careful you are not overstepping your boundaries and violating someone?s copyright law. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Xen, GFS, GNBD and DRBD?
by Tom Lanyon 03 Jan '08

03 Jan '08

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the system into our SAN, so the storage servers do not have a shared storage subsystem. Is it possible to run DRBD on the two storage servers and then export the block devices over the network to the xen hosts? Ideally the goal is to have the effect of shared storage on the xen hosts so that domains can be migrated between them in case one server needs to go offline. Do I run GFS on top of the DRBD mirrored device, exported via GNBD to the xen hosts; or the other way around, using GNBD to export the DRBD mirrored device and then GFS running on the xen hosts? Is this possible; is there an easier/simpler/better way to do it? Thanks, Tom

by Ross S. W. Walker 03 Jan '08

Take a look at iSCSI for the storage servers. iSCSI Enterprise Target is what I use here and it works well for us. You don't really need shared filesystems if you are doing direct block io to LVs or raw partitions as the Xen migration will handle the hand-off, but you will if you are using flat files, because of this I recommend using LVs or raw partitions as clustered filesystems will put a serious overhead on the Xen guest io. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Wed Jan 02 17:44:19 2008 Subject: [CentOS] Xen, GFS, GNBD and DRBD?

Firewall frustration
by Robert Moskowitz 02 Jan '08

Well FWbuilder is NOT easy. The documentation does not match the current GUI. Now the box is locked up. I will have to pull it again, hook it up to a kybd/VGA and reset iptables.... Maybe Shoreline with webmin.... Problem is I want a REAL router/firewall with little work. Both public and private nets have routable addresses. No NATing for me! I just help write the RFC ;) And all the templates for fwbuilder want you to be using NATing. Perhaps I should just set up another Astaro firewall. I have been using Astaro since v3, so I am comfortable with it....

ISO burning challenge -- pilgrims progress
by Robert Moskowitz 01 Jan '08

01 Jan '08

First the Storix drive works just fine under DSL 4.2.1 on my Libretto. So the drive is fine, the media is fine. And cdrecord on DSL reports the media to be Manuf. index: 27 Manufacturee: Prodisc Technology Inc. I have all of ONE system with Centos 4 on it. A Trixbox 2.2; I added cdrecord and found that I could burn the iso image ONLY by including the -force option to get around the "cdrecord: Cannot get disk type" error. So I moved back to the Centos 5 system. I had to add the speed=4 (when the unit supports speed=8) along with the -force to get it to burn a iso image (btw, timeout=100 does nothing. The failure is in a few seconds, adding to the timeout changes nothing). There are a number of timing errors on the Centos 5 system. Even the Centos 4 system had a SCSI error (0x7000). I did find ONE mention of "cdrecord: Cannot get disk type": http://crashrecovery.org/oss-dvd/Changelog.html but that is dated 2/2/06. One would think it is fixed in Centos 5..... I have NOT gotten the HP CDRW working yet, that is the one I want to leave on the server, as the Storix is my traveling drive. More work. Any pointers gladly taken! I REALLY want to move my CD processes to Centos. I want a GUI interface and want to rip and burn music CDs as well.....

Help with full and incremental dumps
by Scott Ehrlich 31 Dec '07

31 Dec '07

I have an Overland Arcvault 12 library with a full LTO3 magazine of 400/800 GB tapes. It is connected directly to the fileserver via a SCSI card/cable. The two main directories I want to back up are /var/log, which is on one filesystem, and /home, which is on another. There are _currently_ no databases to worry about, but there may be active users logged in and active jobs running. We'll just take our chances with what can be backed up. I've successfully run dump/restore to an external USB 1 TB hard drive as our backup device until the tape library arrived. Now, finding the appropriate dump and restore commands to throw into a script is the fun part. The first time will obviously produce a full backup of said directories to back up. Subsequent ones will be incremental. What should my dump lines look like for both full and subsequent incrementals? And, to test the backup and in case I need to retrieve a file, what should a respective restore line look like? Thanks much. Scott

Can't connect to torrent tracker
by William L. Maltby 30 Dec '07

30 Dec '07

Well, yesterday my 5.1 and 4.6 systems could connect to torrent.centos.org OK. Today neither system can connect. I can ping, but that's all. No changes were made to the firewall during this time. Any tips on debugging this? I successfully http downloaded all the ISO images from various mirrors this morning, so I think my net and firewall are OK. TIA -- Bill

Firewall builder - which rpm?
by Robert Moskowitz 30 Dec '07

30 Dec '07

I need a decent, easy, firewall on Centos. This is for test systems, so I do not need a lot. For 'a lot', I use and Astaro firewall. I had used Firestarter once, but found out that it cannot handle routing between a public and private network. Basically saying this is impossible. Of course, if your private network is addressed per RFC 1918 (that I co-authored), I can understand the difficulty, but otherwise.... Anyway, I found firehol, but this is rather confusing. ( how do I define a service like for port 5903? What about UDP for RTP? How do I run the thing?) There have been people here mentioning Firewall Builder, and that seems be well documented, except which rpm I should grab for Centos 5. I am looking over at http://www.fwbuilder.org/ and http://www.fwbuilder.org/nightly_builds/build-329/ for rpms, but which one? fedora-c5 ? thanks.

It appears that xen-libs-i386-3.0.3-41.el5.rpm is only compatible with xen 3.0.3. If I want to install 3.1, where do I find a compatible xen-libs rpm. What exactly is this for, there is no mention on the xen website of this requirement? Thanks! jlc

VIA C3 support for CentOS 5? (i586 kernel)
by Ray Van Dolson 30 Dec '07

30 Dec '07

Hi all. Decided to upgrade an old Slackware 10 box I had. The box is running a VIA C3 processor and apparently doesn't support the cmov extension that most i686 processors do. As a result I cannot install CentOS 5. I discovered a few posts from way back in April: http://lists.centos.org/pipermail/centos/2007-April/079352.html http://lists.centos.org/pipermail/centos/2007-April/079439.html Implying that an i586 version of the installer might be released. Was something along those lines ever done, or could it still be done? Or should I just stick with CentOS 4 for the time being? (I did try 'i586 text' on my netboot 5.1 CD) Thanks, Ray

VooDoo3 = no joy
by Michael A. Peters 30 Dec '07

30 Dec '07

I posted this in the support forum but I suspect I may have better luck here. Old home built PC that has a 3dfx VooDoo3. When I tried installing CentOS 5 on it - the graphical installer would freeze just after starting X - but cli install worked just fine. The failing power supply on the old CRT finally completely died, so I bought a new Dell flat panel (1908FP) and hooked it up. With a new monitor that works, I decided to try X and got no joy - same symptom as the graphical install, completely frozen X display very shortly after starting the X server. The box isn't frozen, I can still ssh in - but keyboard/mouse are frozen (IE impossible to ctrl-alt-FN to switch to a virtual console). The X log in /var/log/ did not have anything that looked like an error - so I ran startx > foo.log 2>&1 and I did get what looks like some error messages - attached as text file. Any suggestions would be appreciated. I may see if I can replace the video card, I suspect finding a video card for this old style of AGP isn't going to be easy, so I'd prefer to have a solution to the VooDoo 3 issue. VooDoo 3 did work with X11 in Fedora Core 6 - the OS I ran before installing CentOS 5. CentOS install is up to date, only CentOS packages that have replaced by non CentOS packages are sox and php (and yes, I'm certain of that).

The OpenMPI package that ships with CentOS 5.1 does not seem to be compiled with torque support. It does, however, seem to be compiled with gridengine and slurm support. Would it be possible to get this changed?

Xen Networking Issue with CentOS 5.1
by Joseph L. Casale 29 Dec '07

29 Dec '07

Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet HWaddr 00:0C:29:4A:69:63 inet addr:192.168.5.30 Bcast:192.168.5.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe4a:6963/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:25 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1763 (1.7 KiB) TX bytes:594 (594.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:336 (336.0 b) TX bytes:336 (336.0 b) peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:28 errors:0 dropped:0 overruns:0 frame:0 TX packets:21 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1943 (1.8 KiB) TX bytes:1314 (1.2 KiB) Interrupt:17 Base address:0x1400 vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:9 errors:0 dropped:0 overruns:0 frame:0 TX packets:25 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:594 (594.0 b) TX bytes:1763 (1.7 KiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:468 (468.0 b) xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1881 (1.8 KiB) TX bytes:0 (0.0 b) Thanks for any pointers! jlc

Hi all, I added the "workspace switcher" and I now have 4 virtual screens. When I do "vncviewer machine" works and shows me the current 1-4 display. however, I want to go directly to one of the 1-4 displays. when I do "vncviewer machine:1" it says "unable to connect to host" How do I get the displays 1-4 to accept the vnc connection? I have module vnc loaded in my xorg.conf file. Again vnc works into the machine but I want to go directly to one of the 4 available virtual screens. Thanks, Jerry

Help with dump/restore
by Scott Ehrlich 28 Dec '07

28 Dec '07

So I recently installed an Overland Arcvault 12 tape library on a server to back up /var/log/ and /home. The server is an out-of-box RHEL 5 install, with all packages selected, in an isolated lan, with no package updates. Also, this is a live server that cannot be brought down for backups, and some files may be actively in use during the dump - just gotta live with it. Since I know EL5 and C5 are the same, and the level of support I get from RH is actually less effective and slower than resources such as this list, I'm looking here, first. Up to this point I was backing up to a USB-mounted external 1 TB hard drive. I was using a script containing: /sbin/dump -0v -z2 -f /media/usb_drive/dump0 /home I played with restore on that, and it tested fine. For the tape, I thought it would be nice to add /var/log (should have done it before, but didn't think of it...) Trying to adapt the knowledge to a tape library... /sbin/dump -0 -v -z2 -f /dev/nst0 /var/log /sbin/dump -0u -v -z2 -f /dev/nst0 /home I have a cron job that dumps the results to /var/log/dump.log, and a review of the log file claims all went well. Now for the restore... I just tried playing with different options of restore, but could not successfully restore anything. I ensured I was in a scratch area so as to hopefully not overwrite current files. What is the proper procedure for dumping and restoring now? Should I be dumping to /dev/nst0/dump? What restore commands would I use to recall a file? I'd like to keep things as simple as possible - people have suggested legato and amanda, but for now, I would think/hope dump and restore would work. Thanks. Scott
