looking for good web based DNS script to check nameservers
by Rudi Ahlers 12 Oct '08

12 Oct '08

Hi all, I'm looking for a good web based script / website that can do a full ananlysis on DNS & namservers. Can someone please recommend something good to use? And if possible, if it could show any errors, or even make suggestions (like "TTL is too high", or " you don't have an MX, please ad one", etc) -- Kind Regards Rudi Ahlers

Any problems in the CentOS Samba?
by Spike Turner 11 Oct '08

Upstream bugzilla says :- Rebasing to Samba 3.0.32 would fix various current RHEL4 bugs. https://bugzilla.redhat.com/show_bug.cgi?id=460904 I have looked at the bugs.centos.org but did not find user reported bugs. Is anyone experiencing problems using the CentOS 4 samba? Spike.

Atheros AR5212/AR5213 wifi not working
by Marko Vojinovic 11 Oct '08

11 Oct '08

Hello everyone, I'm new to the CentOS list, so forgive me if this has been answered before (someone please point me to an efficient way of searching through the list archives). I have a wifi card from the subject line, and have the driver installed. Using NetworkManager under Gnome everything works perfectly. However, I prefer to use network service instead of NetworkManager since a) I use KDE and NetworkManager fails to work properly there b) this is a desktop machine, online 24/7 and I want wireless active even when I am not logged in. But when I use the network service, wifi0 fails after a delay, and /var/log/messages says there are no dhcp offers available. However, I am sure that there are several wireless networks available, with a strong signal. How to solve this? I would even accept using NM if it works as a daemon, ie even if I'm not logged in, and under KDE (which it doesn't atm). I believe the problem is essentially in the (in)ability to choose the appropriate network automatically --- in KDE NM doesn't have the taskbar applet which would let me choose the network, and the network service has no way of automatically making such a choice either... Please help! Btw, this is somewhat urgent, I am supposed to make it work by monday, Oct. 13. Oh, I almost forgot, CentOS 5.2, fully updated. Best, :-) Marko

Something like: TFIL=/usr/tmp/dummy$$.txt grep -Ilr "$STR" * > $TFIL for fil in $( cat $TFIL); do sed -i "s/$STR/$NEW/g" $fil done Man grep says: "-I Process a binary file as if it did not contain matching data". Also -l gives you the filename and relative path. If $STR contains "/"s then you could use # instead. sed -i "s#$STR#$NEW#g" $fil I dont know how much the searched for string would change, but you could test if it contained "/" and then use sed with "#" instead. Also you might want to use "sed -ibak ..." instead since this will backup the unchanged file to filename.bak, should your substitution go awry. The letters after "i" specify the extension you want to use. Eric Sisolak

Fwd: P5GC SATA mode problem
by Eduardo Grosclaude 10 Oct '08

10 Oct '08

Hello, I'm top-posting my own thread with some homework I've done, can somebody help? In short, the problem is that kernel 2.6.18-53 (as per 5.1 installation) works OK while any kernel update makes booting impossible in Enhanced SATA mode. For newer kernels, only Compatible mode works, but at a very heavy cost in performance. The motherboard is ASUS P5GC-MX and the disk is ATA WDC WD3200AAJS-6. More detail in my own former message at the end. 1. I have tried pci=nommconf, noacpi, acpi=off. Any other hints? 2. I've opened up both initrd files (initrd-2.6.18-53.el5.img, which works in "SATA/enhanced" mode, and the newer initrd-2.6.18-92.1.13.el5.img, which only works in "compatible") and found practically no differences (USB modules are loaded in a different order and that's about it). 3. In the hope that I could build up a working kernel (albeit sacrificing ease of update) I tried to figure out some useful config. I've scanned both config-XXX files but I am unable to identify any reasonable suspects either, diff provided below. Should SCSI-SAS-ATA be different? 4. Just to play a while, attempted to make mrproper and got the following. Same for make clean. [root@localhost 2.6.18-92.1.13.el5-i686]# make mrproper scripts/Makefile.clean:17: /usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile: No such file or directory make[3]: *** No rule to make target `/usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile'. Stop. make[2]: *** [drivers/infiniband/hw/amso1100] Error 2 make[1]: *** [drivers/infiniband] Error 2 make: *** [_clean_drivers] Error 2 So it seems 5.2's kernel really doesn't like me. Now, my questions: 1. What is going on? What can I read to understand a bit more? 2. As for the disk drive behaviour, should I file a bug? I haven't found any related known bugs. Does it depend on whether ASUS P5GC-MX is or not on the HW CL? 3. Is it on the HW CL anyway? I assume it is, from what I read at http://www.linux-tested.com/results/asus_p5gc-mx.html 4. As for the kernel compile error, what is going on again? Any hints deeply appreciated!

My 5.2 DVD refused to see the hard disk. As the CD happened to have a bad MD5 sum, I assumed this was due to a bad burnt image. Backed off to 5.1. Installation of 5.1 to /dev/sda went OK, then I upgraded by yum to 5.2. But, at the next boot, the new kernel can't see the disk. Only when BIOS IDE Setup is "compatible" I can boot the new kernel. However, the disk shows up as /dev/hdc and performance is noticeably slow. If I choose any other mode, nash complains that any LVM groups can't be found and panics away. I/O in general is terrible. Copying a CDROM to a file with dd renders the machine nearly unusable. The kernel provided in 5.1 can work in the BIOS IDE Setup "enhanced/SATA" and performance is really good. Hdparm when under the current kernel says 3.51 MB/s buffered speed, whereas for the older kernel it claims some 111+ MB/s. I have updated the BIOS ROM to no avail. What am I missing? Is there anything I can do except keep trying kernel updates?

Xboard rpm for CentOS 4

Has anyone built an rpm for xboard for CentOS 4? I looked in the EPEL repo, KBS repo and rpmforge but none exist. The KBS repo has gnuchess in testing but what good is gnuchess without xboard? As usual the fedora SRPM for Fedora 6 and Fedora 9 cannot build on CentOS 4- they might build on CentOS 6 but i have no time machine :).

Installing a new VM on a xen box.
by James B. Byrne 10 Oct '08

10 Oct '08

HW = HPQ DC7700 DuoCore 1.8GHz, 4 x 2GB RAM, 1 x 1TB SATA (AHCI) OS = CentOS-5.2 ix_64 (xen) I am experimenting with Xen and with virtual machines in general for the first time. In consequence I have many questions. However, the one that I wish answered at the moment is simple: Given a DVD containing the CentOS-5.2_Final (i386) distribution mounted at /media/CentOS_5.2_Final on Dom0, what argument do I pass to the "Install Media URL" argument of the "Create a new virtual system" wizard" to install the 32 bit version of CentOS-5.2 onto a vm called test-1? I have tried things like: /media/CentOS_5.2_Final /media/CentOS_5.2_Final/images /media/CentOS_5.2_Final/images/diskboot.img etc. All attempts produce the same negative result. What URL is used to load the 32 bit OS from the dvd? I am a digest subscriber so the favour of a direct copy of any reply to the list is appreciated.

Video driver questions
by Robert Moskowitz 10 Oct '08

10 Oct '08

My OQO has a VIA chipset. From the hwconf: class: VIDEO bus: PCI detached: 0 desc: "VIA Technologies, Inc. CX700M2 UniChrome PRO II Graphics" vendorId: 1106 deviceId: 3157 subVendorId: 1106 subDeviceId: 3157 pciType: 1 pcidom: 0 pcibus: 1 pcidev: 0 pcifn: 0 When I install Centos, I default to the vesa driver, and it operates at the monitor's native 800x480. Of course I want more and to physically scroll the screen to see all of the content (the OQO has slide bars on it that do cause the current active window to scroll). When I change the monitor settings to Generic LCD 1024x768, I get that and 800x600 as an option. If I change the screen resolution to either 800x600 or 1024x768, and log out of X and log back in, my resolution is unchanged at 800x480. So I tried using the VIA driver that comes with Centos. It does not list the CX700, but, you know, give it a try. At first I get errors from X when logging in, finally I get changes to occur, but I am still at 800x480. Selecting 800x600 or 1024x768 mkaes no difference. Below is my /etc/X11/xorg.conf. Any ideas on what to try? # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" ModelName "LCD Panel 1024x768" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 31.5 - 48.0 VertRefresh 56.0 - 65.0 Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "vesa" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

More Samba Questions
by Joseph L. Casale 10 Oct '08

10 Oct '08

I have never setup a Samba server, and the recent thread here prompted to get on this I need to migrate two XP machines from using iSCSI to Samba. I thought the "+" preceding a username in the smb.conf file for a share definition told Samba to use the unix username? Unless I actually use swat to create and enable the user and take off the + it doesn't work. Any ideas what swat does when you create a user through that interface? Is there any way to simply force Samba to use locally created users in the share definition? Thanks! jlc

Firefox3 for CentOS4 -- dependency on evolution28 packages?
by Bart Schaefer 10 Oct '08

10 Oct '08

I'd been putting off installing the FX3 packages because of some extensions I use that don't have upgrades. [*] However, when FX1.5 crashed on me today I decided to finally go ahead. Fired up yum and I'm told I have to install a slew of evolution28 library packages in order to install the firefox package. Why? I removed evolution from my system for a reason, and I'd just as soon it stays gone. [*] Additional off-topic rant: Why was the API access to form history removed from Firefox? Why must I throw away my entire history to get rid of a few typographical errors to reduce the number of bogus field completion choices I'm offered?

Thunderbird does not follow url links in Firefox
by Theo Band 10 Oct '08

10 Oct '08

Since the recent update from firefox2 to firefox3 the links in my mails do no longer work. No window pops up. After some debug I found the problem. Let's share it with others that experience the same problem: I'm using Thunderbird 2.0.0.17 (manually downloaded, that might have caused the problem, I have not tried with 1.5) I'm using Firefox 3.0.2 (yum installed CentOS 4.7) To solve I created a small wrapper script that unsets LD_LIBRARY_PATH: cat <path>/firefox_wrap #!/bin/bash unset LD_LIBRARY_PATH firefox $@ To start add : user_pref("network.protocol-handler.app.http", "<path>/firefox_wrap"); to ~/.thunderbird/<salt>/prefs.js (or use the advanced config editor) The error message (for those Googling around): /usr/lib/firefox-3.0.2/firefox-bin: /opt/thunderbird-2.0.0.17/libnss3.so: version `NSS_3.12' not found (requiredby /usr/lib/firefox-3.0.2/libxul.so) Cheers, Theo

Samba 3.0.28/3.0.32
by Spike Turner 10 Oct '08

10 Oct '08

I've looked at the CentOS docs-list as well as the Wiki as I was interested in Samba. On one CentOS box I've got 3.0.32 (the latest bug-fixed version from Samba.org) and on another I've got 3.0.28 (the latest from upstream). The docs look almost the same and the docs refer to security = share. However 3.0.32 comes with a blank smb.conf making it harder to get a secure server up and running. Is there a plan for a quick and dirty guide on the Wiki for setting up Samba with secure settings as well as TDB rather than deprecated settings? In tips and tricks there is http://wiki.centos.org/TipsAndTricks/WindowsShares Without writing a book as someone suggested, a few one-liners could be put together in the wiki. Spike

rpmforge has just released a new perl-DBD-mysql for el4 that has an obsoletes against perl-DBD-MySQL and the protectbase yum plugin doesn't grok obsoletes. the priorities plugin does. so if you are having issues with this, install the yum-plugin-priorities first, make sure that the CentOS-Base repo is priority 1 and the rpmforge repo is priority 2 or higher (99 is the default). also, i'd like to suggest that the priorities plugin be made added to the base install and that the centos-base repos be configured with priority 1. it looks like c4 has the priority setting, but c5 doesn't and neither have the plugin installed. it seems like this would create a little more stable setup for people when they start adding other repos.

Apache Charset vs html file charset
by Spike Turner 09 Oct '08

09 Oct '08

The apache httpd.conf has AddDefaultCharset UTF-8 while the page I'm viewing on my CentOS server is charset=ISO-8859-1 The page appears funny on the browser showing �� Given that apache has the default charset shouldn't it honor it? Why the �� characters? Spike.

find cont'd 3
by tony.chamberlain＠lemko.com 09 Oct '08

09 Oct '08

Another question about find. I looked at the gnome tool and tried to simulate what it is doing. I can't use it directly because it won't do sed. Basically I want to find all files with a string (except binary) and change it. let STR be the string I am looking for. NEW is new string. I am doing TFIL=/usr/tmp/dummy$$.txt find . -type f | while read fil do grep "$STR" $fil > $TFIL [ $? -eq 0 ] || continue ## does not match if [ "$(cat $TFIL)" = "Binary file $fil matches" ] then continue # Don't operate on binary files fi sed -i "s/$STR/$NEW/g" $fil done (I will have to do something with sed in case there is "/" in the string) Problem is, the grep redefines my stdin so it no longer comes from the list of files that "find" found, and it then terminates after finding the first file. Anyway to "push" stdin on the stack or something before the grep, and "pop" it again afterwards, so it goes back to the list of files found?

Request for additional patch in CentOS Plus kernel
by Filipe Brandenburger 09 Oct '08

09 Oct '08

Hi, I have an Adaptec eSATA card, model 1225SA: http://www.adaptec.com/en-US/products/Controllers/Hardware/sata/entry/AAR-1… Although the chipset is sata_sil24, it is not recognized by default by the kernel because its PCI ID is different than the ones recognized by this driver on the CentOS kernel. The driver recognizes PCI IDs such as 0x3132, 0x0242, 0x3131, but not 0x0244, which is the one this card has. I found out that it works with the latest kernel, and that the patch to make it work only adds the 0x0244 PCI ID to the list of IDs recognized by the sata_sil24 driver. Here is the patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdi… Following the instructions on the Wiki, I built a custom kernel based on the CentOS Plus kernel, but adding this patch. The adapter worked as expected with that kernel. So I ask: Would it be possible to incorporate this patch to the default set of patches applied on the CentOS Plus kernel? I would really appreciate it since that would make it easier for me to keep updated without worrying about the card. Thanks a lot! Filipe

Question on Wireless Setup
by Ashish Vijaywargiya 08 Oct '08

08 Oct '08

Hello Akemi & Others, Today I reformated my laptop Dell Precision M90 and installed the Fresh version of CentOs 5.2 and then took all the available update. In that update I got Kernel version update and now I am on Kernel-2.6.18-92.1.10.el5.centos.plus. I kept a file iwlwifi-3945-1.ucode into the /lib/firmware/ Now after restarting the computer my computer it is giving the following message on the startup. Bringing up interface wmaster : Determining IP information for wmaster .... SIOCSIFLAGS : Operation not supported. In the network manager it is showing my device i.e Intel Pro 3945 adapter but in the Inactive state. Please give me some suggestion so that I can figure out this problem. Thanks in advance. -- Ashish Vijaywargiya Indore (M.P), India http://en.wikipedia.org/wiki/Indore

Slightly OT: Dell Poweredge 2850 with 4GB RAM
by Sorin＠Gmail 08 Oct '08

08 Oct '08

Hi all, I got the previously mentioned Dell Poweredge 2850 with 4GB RAM and Perc4e raid controller. Installation went well and the raid is pretty fast even with level 5. However I have another problem now... CentOS 5.2 only sees 256MB RAM. Googling a bit, got me to install kernel-PAE, this went well, but CentOS still sees only 256MB. Googling some more, I found a bios update was suggested and might do the trick. Checking what bios version the server had, revealed it was A02. Upon checking the Dell support site I saw they had a version A07, which I downloaded. The file was in bin format and executable via the CLI. Installation of the A07-version went well too with no errors, and it told me to reboot the machine to activate/start the update. Upon reboot, at post, it said the update failed. Now what?? I'm at a loss here. This is my first Dell Poweredge-server and I lack knowledge in the tricks-department with this one. What do I do now? Knowing the Dell-support, I turn to this list in hope of some useful hints in this matter. Thx for any insights. -- Best Wishes Sorin --------------------------------------------- http://home-skynet.servehttp.com/ Proud member of TEAM OS/2.

Samba 3.0.28/3.0.32
by Spike Turner 08 Oct '08

08 Oct '08

I've looked at the CentOS docs-list as well as the Wiki as I was interested in Samba. On one CentOS box I've got 3.0.32 (the latest bug-fixed version from Samba.org) and on another I've got 3.0.28 (the latest from upstream). The docs look almost the same and the docs refer to security = share. However 3.0.32 comes with a blank smb.conf making it harder to get a secure server up and running. Is there a plan for a quick and dirty guide on the Wiki for setting up Samba with secure settings as well as TDB rather than deprecated settings? In tips and tricks there is http://wiki.centos.org/TipsAndTricks/WindowsShares Without writing a book as someone suggested, a few one-liners could be put together in the wiki. Spike

The difficulty with this is that it requires yet another host, a reconfiguration of the existing wiring plan, and dealing with a number of other issues which directly arise from the first two requirements. We already use IPtables, and we already have some of our older hosts secured behind sshd linux boxes so that network traffic to them is only carried en clair across direct x-wired patch cables. > If your not well versed in routing I wouldn't recommend > going around making a bunch of changes to a system that > I assume has been more or less working for more than > a decade. Which is why I asked the question if by making a single change to the network parameter of the Cisco Router could I avoid: 1. Physically segmenting my LAN 2. Having to commission an additional host or reconfigure an existing host to multi-homed. Routing is something I do not go at very often and I do not trust my memory for such things in consequence. The manuals and books that I have give sketchy coverage of this aspect and use examples much more narrow in scope than I contemplate. It would be a gross over-statement to say that I am unfamiliar with the concepts of routing. But I am asking for specific guidance on specific software (CISCO ISO 12.x) and hardware (CISCO 26xx series) from someone with experience in these matters. I recognize that this is not the precise forum to ask, thus the OT. On the other hand, I trust that my situation cannot be very dissimilar to those faced previously by many system administrators who also happen to run CentOS.

OT: RIP settings for private netblocks
by James B. Byrne 07 Oct '08

07 Oct '08

I am contemplating converting some of our internal networks from routable to private IPv4 address space. I have a question about RIP as implemented under Cisco IOS 12.x. Presently the setting for rip is: router rip version 2 passive-interface [[FastEthernet]]0/0 network aaa.bbb.ccc.0 no auto-summary What I would like to know is how one routes the entire 192.168/16 address space using rip. My perusal of the various Cisco manuals, technical documents and various O'Rielly books is not giving me any clear answer and I am rather reluctant to experiment on our live Internet connection. Will this do what I imagine it might, treat any address 192.168.x.y or 10.x.y.z as an internal network? router rip version 2 passive-interface [[FastEthernet]]0/0 network aaa.bbb.ccc.0 network 192.168.0.0 network 10.0.0.0 no auto-summary Regards, -- *** E-Mail is NOT a SECURE channel *** James B.

ejabberd 2.0.2 vs SELinux vs CentOS 5
by Damian S 06 Oct '08

06 Oct '08

Lordy, I've been having problems with this darn thing, so I hope someone can help me. :s My troubles started when I downloaded the latest erlang and ejabberd packages. I crashed and burned very quickly, trying two or three different versions of erlang along with several of ejabberd 2.0.x. Finally, after a week of pain, I admitted defeat, wiped the whole lot and installed the binary on the process-one website. Initially, the binary worked well, but mysteriously stopped working whenever I changed the config file and restarted the file. Anyway, to cut a long story short, I have discovered that SELinux is preventing erlang from accessing its crypto libs. This message appears in the SELinux audit logs: type=AVC msg=audit(1223133076.770:102): avc: denied { execmod } for pid=3878 comm="beam.smp" path="/opt/ejabberd-2.0.2_2/lib/crypto-1.5.2/priv/linux-x86/lib/crypto_drv.so" dev=dm-0 ino=26738869 scontext=user_u:system_r:unconfined_t:s0 tcontext=user_u:object_r:usr_t:s0 tclass=file What do I need to do, for selinux to allow this? (Or should I take this question to an SELinux list?) FWIW, ejabberd seems to run fine while selinux is enabled. Its just when starting up, that it needs selinux to stay out of the way.

find - text
by tony.chamberlain＠lemko.com 06 Oct '08

06 Oct '08

A while ago I sent mail about wanting to find all files that had a certain text string in it and changing it to something else. People mentioned that there is a system tool to do it (gnome has it too). I ran this, for example to find all files WITH "prog" in the name, and then I did a ps and I saw simply find . -iname '*prog*' then I did something similar, all file names but with "prog" in it, and found basically two lines (one was child process of the other, so I assume it was a pipe or something): find . -type f grep -i -c prog this does a grep for case insensitivity for "prog", so basically the tool uses find and grep. I could do something like find . -type f | while read fil do sed -i 's/prog/name/g' $f # change "prog" to "name" done A couple problems here. If what I am changing is the same length then it may be ok. But consider this quick (example) C program state.c int main( int argc, char **argv ) { printf( "Ohio\n" ); } if I compile it to "state" and then print it prints Ohio. If I do (on the compiled file state) sed -i 's/Ohio/Utah/' state then it will print Utah. However, if I change the length sed -i 's/Ohio/Michigan/' state it will of course SIGSEGV because it changed some of the object code. (Actually even doing the same length can be dangerous). What I want to do is either provide another option to the find (which I can'e seem to find), or pipe the files it finds to something like "file" to get only ASCII files (non-object code). However, I am not sure how to do this. On most files, the "file" command will return something with "text" in it, but not all files. For instance, sometimes it returns "application" or "shell script" but it is still OK to do the sed on these. Is there some easy way to take a file name and determine whether sed -i can safely be done on it (i.e., it is ASCII and not some sort of binary file)? Tony

Boot disk order: h/w vs. grub
by MHR 06 Oct '08

06 Oct '08

I'm still having conceptual trouble with this one. I have two PATA and two SATA disks in my home system. When the system comes up, these are, espectively, /dev/hda, /dev/hdb, /dev/sda and /dev/sdb. I have the boot order of the drives in the boot PROM set to boot from /dev/sda (hard drive 2), then /dev/hda (hd 0), and usually that works fine. /dev/sda is properly set up with the MBR and /boot lives there as well. However, when the system has to be shut down, usually for some length of time more than just a few seconds, when it comes back up, it can't find the boot image. I forgot how I got around this the first time. The second time, when it wasn't booting past the "GRUB" part of the grub announcement, I used the installation disk, booted into linux resuce mode, chroot'd to the actual system disk and re-did grub-install. Still, a few days later (last Tuesday) when my video card went south, I just edited the grub boot line to use root(hd2, 0) and it came up, followed by several reboots with unmodified grub config lines. I guess I'm wondering if there's some more permanent way around this issue. Do I need to overwrite the MBR on hd0? Should I reconfigure the system so the PATA drives are not connected to the m/b at all (i.e., usb enclosures)? Is this a bug in grub? All this is assuming that I do not get rid of the PATA drives and/or get a new m/b that has <something else>.... It seems strange that this should be such a pain, even though in a rather oddball way it makes sense. Thoughts? Thanks mhr

mysqld breaks yum, help?
by Dac Chartrand 06 Oct '08

06 Oct '08

Greetings. After doing: $ yum install mysql-server $ /etc/init.d/mysqld start Yum is broken. Example: $ yum list php Loading "fastestmirror" plugin Loading "priorities" plugin Loading mirror speeds from cached hostfile * utterramblings: www.jasonlitka.com * base: mirror.nuvio.com Traceback (most recent call last): File "/usr/bin/yum", line 29, in ? yummain.main(sys.argv[1:]) [..snip..] File "/usr/lib/python2.4/threading.py", line 416, in start _start_new_thread(self.__bootstrap, ()) thread.error: can't start new thread I have the priorities plug-in setup. I did `yum update` before messing around with 3rd party repositories. The only modules I installed from the 3rd party sties are PHP related. More importantly, if I do `/etc/init.d/mysqld stop`, yum works fine. So it's only failing when mysqld is turned on. Can someone offer some insight here? Thank you for your time. $ cat /etc/redhat-release CentOS release 5.2 (Final) --- http://www.sux0r.org/
