script help - '3rd last field'
by Tom Brown 08 Jun '09

08 Jun '09

Hi I need some logic to work out a value for me - this value is _always_ the 3rd last field in a string seperated by '.' but the string could be 5 or 6 fields long, e.g foo.bar.VALUE.baz.lala foor.bar.gigi.VALUE.baz.lala I need to find VALUE - if this were python or something i could do it but this has to be in shell - Any clues? thanks

Dell Poweredge R300

Hi all, Just found out that the Poweredge R300 cant even load the CentOS 5.2 64bit installer. Had to revert to Ubuntu. Seems its a driver problem. Pity, but does this kind of case apply to many other servers? --- OSCC MAMPU MyMeeting Version 2.0 Release http://knowledge.oscc.org.my/solution-areas/application/mymeeting

OT: looking for a rsync equivalent for Windows platforms
by Rudi Ahlers 07 Jun '09

07 Jun '09

Hi all, Does anyone know of a good & free rsync type program for Windows platforms? Like most of us, I need to work on both Windows & Linux environments, and would like to sync some data (music, videos, photos, documents, thunderbird profiles, FF bookmarks, etc) between a USB HDD, my Linux (CentOS + KDE) PC, and Windows Laptop at the office. I found a program called Toucan (which also has a portable version) but it doesn't seem to work as well as rsync. When I tell it to "sync (copy)" or "sync (mirror)" file between the USB HDD, or even my Linux PC via the LAN, it copies every single file, every time. So it's not very efficient. Their forums doesn't have much help on this matter, and I just know from experience that help here is much better ;) -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

[OT] Simple Shell Script (while loop)
by James Bensley 06 Jun '09

06 Jun '09

Hey Guys, I can not find the corrent syntax for what I am trying to acheive with a while loop. Having said that I'm not exactly sure what you would call it so I have been googling with no success probably for that reason. I am just working with some sub directories except there is one I don't want to use so I have a while loop like the following; if we stubmle into the sub directory I wish to leave alone then there is an IF statement and I have used the break command which is wrong, I don't want to end this whole loop I just want to skip onto the next increment of the loop as it were skipping this sub directory. Break is the wrong command but what should it be? Sorry I can't be any clearer but I don't know exactly what you would call this (which is why I am having no success finding it for my self!) #!/bin/bash find ./ -maxdepth 1 -type d | while read FOLDER do if [ $FOLDER == "./not_this_folder_oh_no!" ]; then break fi <otherwise do some magic here> done Many thanks for your time and input. Regards, James ;) -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT/MU/U dpu s: a--> C++>$ U+> L++> B-> P+> E?> W+++>$ N K W++ O M++>$ V- PS+++ PE++ Y+ PGP t 5 X+ R- tv+ b+> DI D+++ G+ e(+++++) h--(++) r++ z++ ------END GEEK CODE BLOCK------

question on whiptail
by Jerry Geis 06 Jun '09

06 Jun '09

There is a script that uses whiptail command. Is there a way to wrap the script that calls whiptail 4 times and just send a carriage return to each character window that pops up? I want it to basically just accept the default option for each of the four prompted windows. without me hitting return 4 times. How do I do that? I tried unsuccessfully: script_calling_whiptail << EOF \n \n \n \n \n EOF ~ I dont want to change/edit the script as it may change again in the future. Thanks Jerry

Server Build Example
by gene.poole＠macys.com 06 Jun '09

06 Jun '09

I'm coming from the Fedora arena and I want to build, what I would call, a production server. I'm to the point where I don't want to upgrade every 6-months. I'm running Oracle DB 11g, a Tomcat/JBoss hybrid application server, and several other server type functions. Is there an example of building a server that boots into init3? Thanks, Gene Poole

CPU usage over estimated?

I have a quad core CPU running Centos5. When I use top, I see that running processes use 245% instead of 100%.

Swap priorities with swapon (Is my swap drive working?)
by James Bensley 05 Jun '09

05 Jun '09

Hey Listee's I have a CentOS server with 2GB of ram and a swap drive of 4GB; swapon -a shows my swap drive as 4GB with only about 350 bytes in use (which is fine as my server idles with about 350-400MB ram usage so no swap should be in use. However my one and only swap drive had a priority of -1. I had read that the swap drive priority doesn't matter too much because I only have one swap drive so the kernel hasn't got to make a choice but also that after a certain kernel version (which is think was like 1.3.x?) it didn't even use the priority value and my kernel is newer (I have 2.6.18-128.1.6.e15). Basically I have read difference things from difference source on the old interwebwrok and seek clarification. In the confusion I set my swap drive priority from -1 to 1 because I thought that if the drive priority were a negative value it might not actually use the swap drive. Ultimately I can't tell because there currently isn't enough memory usage demand on the server. On a side note: I'm a reformed Windows admin and have seen the light and am moving each server one at a time over to Linux so I am used to poor memory management and needing massive page files. Realistically the swap drive shouldn't been in use but I am just worried then when this server goes live it will hit 2GB of ram usage and the swap won't kick in. Is there anyway I can check? Thanks for reading.

But obviously it isn't sufficient for the BCM4312. eth0 works well (although DNS dies on a regular basis, for which there are a lot of heated discussions about NetworkManager and dns on the various linux sites). eth1 is not found and when I right-click on the NetworkManager icon on the top right corner of the screen, it shows a wireless in a grayed out text. When I go to System>Administration>Network, I cannot enable the wireless (eth1) device. It tries and then after trying to find an IP, it fails.

DRBD+GFS - Logical Volume problem

I'm working my way through the xine FAQ concerning performance to see if I can fix that on this laptop. The laptop is only about 18 mo old and not a dog. It is an Intel duo with 2GM of ram, and should have enough steam to play a dvd. It plays them well under MS Vista, but jerky under Centos 5.3 and xine, so it has to be a software issue.

Good md5sum snapshot tool?
by Sean Carolan 04 Jun '09

04 Jun '09

I have a server that is undergoing some patching soon and would like to make note of any files that have changed after the patching is complete. Can you recommend a tool that uses md5sum snapshots to do a quick before and after test, showing anything that's changed on a particular file system?

Dovecot under brute force attack - nice attacker
by henry ritzlmayr 04 Jun '09

04 Jun '09

Hi List, optimizing the configuration on one of our servers (which was hit by a brute force attack on dovecot) showed an odd behavior. The short story: On one of our servers an attacker did a brute force attack on dovecot (pop3). Since the attacker closed and reopened the connection after every user/password combination the logs showed many lines like this: dovecot: pop3-login: Aborted login: user=<test>,...... The problem: If the attacker wouldn't have closed and reopened the connection no log would have been generated and he/she would have endless tries. Not even an iptables/hashlimit or fail2ban would have kicked in. How to reproduce: telnet dovecot-server pop3 user test pass test1 user test pass test2 ... QUIT ->Only the last try gets logged. Question: Is there any way to close the connection after the first wrong user/pass combination. So an attacker would be forced to reopen it? Any other Ideas? Henry

I've recently read: Linux Find Out If PCI Hardware Supported or Not In The Current Running Kernel<http://www.cyberciti.biz/tips/linux-find-supported-pci-hardware-drivers.html> So, if I: grep 27d8 /lib/modules/$(uname -r)/modules.pcimap and see this: snd-hda-intel 0x00008086 0x000027d8 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 then it's sure that my PCI Hardware is supported? I Don't need anything to do? Is there a way for lsusb too? How could I know that my hardware (connected to my pc or not) is supported? - sorry for asking this: but is there a "devmgmt.msc" (windows..) "like" software, solution under Linux, where can I see that is my pc's hardwares recognized correctly? Thank you

The issue with the "file" package was a completely different one than the issue with the unsubscriptable object - although yum clean metadata has solved that one for most people as well.

"print notifier" icon
by Frank Cox 04 Jun '09

04 Jun '09

The Print Notifier icon appears in on my Gnome panel when I print something. After the job is completed, the icon grays out, but it's still present. With my Fedora setup, the icon appears when the job is active or pending, then it goes away completely until the next time I print something. How can I make Centos 5.3 do the same thing? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Instability with later 4.x kernels?
by Benjamin Smith 04 Jun '09

04 Jun '09

I have an Athlon with about 10 HDDs plugged in, primarily to do Disk2Disk backups. Some drives are PATA, some are SATA, some are USB. A strange concoction, but it's been relatively stable for some 4-5 years, despite numerous upgrades and so on. It's been running CentOS 4 for a long, long time. (years) Recently, I've started to have problems with its stability, and after 2 weeks of swapping hardware, found that using an earlier kernel restores its stability! It takes a few days to determine if anything "goes south", so debugging is very, very slow. But I get random read errors, either SCSI errors or (a few times) HDA read errors. Once the read errors begin, the system becomes very unresponsive, and often won't restart, even though I wait for hours, without my hitting the "kill switch". # uname -a Linux backuphost 2.6.9-67.0.22.EL #1 Wed Jul 23 17:17:45 EDT 2008 i686 athlon i386 GNU/Linux The failures occur on all /dev/sd* devices, even those that are USB. Once, /dev/hdc had a similar problem after /dev/sdb had failed. Don't know if the mapping below helps? /dev/hda - PATA, on motherboard, 20 GB. /dev/hdb - IDE CDROM /dev/hdc - on motherboard 500 GB IDE /dev/hdd - on motherboard 300 GB IDE /dev/hde - on PCI card, 500 GB IDE /dev/sda - SATA, on a PCI card, 1 TB /dev/sdb - SATA, on a PCI card 1 TB /dev/sdc - USB on a USB 2.0 PCI card, 750 GB /dev/sde - USB on a USB 2.0 PCI card, 750 GB /dev/sdf - USB on a USB 2.0 PCI card, 1 TB Here's what I see in the /var/log/messages: May 27 05:08:42 hume ntpd[4844]: kernel time sync enabled 0001 May 27 08:01:01 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 08:01:01 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 08:01:01 hume kernel: EXT3-fs error (device sda1): ext3_find_entry: reading directory #2 offset 0 May 27 08:01:01 hume kernel: May 27 08:14:27 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 08:14:27 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 08:14:27 hume kernel: EXT3-fs error (device sda1): ext3_find_entry: reading directory #2 offset 0 May 27 08:14:27 hume kernel: May 27 10:28:30 hume ntpd[4844]: synchronized to 63.240.161.99, stratum 2 May 27 11:48:07 hume sshd(pam_unix)[26873]: session opened for user root by (uid=0) May 27 11:48:10 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:10 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 11:48:10 hume kernel: EXT3-fs error (device sda1): ext3_find_entry: reading directory #2 offset 0 May 27 11:48:10 hume kernel: May 27 11:48:16 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:16 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 11:48:16 hume kernel: EXT3-fs error (device sda1): ext3_readdir: directory #2 contains a hole at offset 0 May 27 11:48:23 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:23 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 11:48:23 hume kernel: EXT3-fs error (device sda1): ext3_readdir: directory #2 contains a hole at offset 0 May 27 11:48:24 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:24 hume kernel: end_request: I/O error, dev sda, sector 12847 May 27 11:48:24 hume kernel: EXT3-fs error (device sda1): ext3_readdir: directory #2 contains a hole at offset 0 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 0 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 0 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 8 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 1 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 16 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 2 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 24 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 3 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 32 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 4 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 40 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 5 May 27 11:48:38 hume kernel: SCSI error : <0 0 0 0> return code = 0x40000 May 27 11:48:38 hume kernel: end_request: I/O error, dev sda, sector 48 May 27 11:48:38 hume kernel: Buffer I/O error on device sda, logical block 6 ..

XSS (was Re: Centos 5.3 -> Apache - Under Attack ? Oh hell....)

Mozilla is beginning to address this issue with Content Security Policy -=- http://people.mozilla.org/~bsterne/content-security-policy/ -=- CSP will require pro-active webmasters who use it and browsers that enforce the client side enforcement, but it's a step in the right direction. I wrote a php class that partially implements CSP server side as an output filter -=- http://www.clfsrpm.net/xss/ -=- It's DOMDocument based and thus requires the php xml stuff, I've only tested it under php 5.2.9 but it should work in 5.x. The class does have some limitations, namely the document must be fully constructed and sent through the class before any of it is sent to the browser so web apps that do a lot of echo() and print() have to be re-written to not send anything until the page is fully constructed, and I've also found it has performance issues on complex pages with a lot of nodes, so for those kinds of pages I just create the page with the dynamic content first, send it through the filter, then create the nodes for static content I know is clean and use DOMDocument facilities to add those nodes before outputing the page to the client. It's not possible to completely implement CSP server side, but the class will catch most violations of a CSP policy and thus give some protection to users who are not running a CSP aware web browser. Another gotcha with the class, it seems importHTML() is not mb safe so if using importHTML() to get the document into a DOMDocument object for filtering, and the document contains any multi-byte characters, it seems libxml2 will encode them and there seems to be no way to stop it from doing it (at least with the php wrapper to libxml2). However if the document to be filtered is xhtml, you can use importXML() on it libxml2 does the right thing in leaving the mb characters alone. Once filtered, you can use saveHTML() to produce html instead of xhtml for browser compatibility, it seems saveHTML() is mb safe.

NOOBE help
by Sam Drinkard 03 Jun '09

03 Jun '09

I know, I should not have to ask this question, but it appears that ALL my previous yum.repos.d entries have been trashed, with the only ones left is base, CentOS Media then the mirrors.rpmforge.reo, rhel-mondo.repo, rpmforge.repo, and webmin.repo. I've been bitten by the mixing of repositories before and want to avoid that scenario. Something is amok in the existing, and it throws all kinds of errors about something not found or such, so I'm asking some kind soul of they would share their working repo file structure for me? I *think* I have protect base, and priorities installed already, but will double check. This is yet another new clean install after a botched attempt to recover some data from a mondo-rescue DVD which apparently dis some ugly things to stuff including grub. Anyhow, my main items of interest would be stuff like clamav-milter, spamass-milter, and anything else dealing with handling spam, not to mention some other scientific software like udunits, perhaps Grads (if exists), etc.. all geared towards weather. My humble thanks and apologies for my dumbness for not keeping good backups of important stuff.. it WONT happen again ! head hanging low :( Sam

how to debug random server reboots

Hi all, One of our CentOS 5.3 randomly reboots, at different times of the day, and I can't see why it's doing it. I have looked through the logs, but don't see any thing in there that shows me why it has rebooted. How can I debug this? Here's a snipped from the log, around the time of the reboot: Jun 2 14:59:59 usaxen02 kernel: EXT3-fs: mounted filesystem with ordered data mode. Jun 2 15:00:06 usaxen02 kernel: kjournald starting.

Sometimes it will go for days without rebooting then today it has rebooted 6 times at random times. I have modified grub.conf to go back to 2.6.18-92.1.22.el5xen on my dom0 and my only domU so we will see what happens (or hopefully doesn't happen) the next few days. I have a 3.0 P4 CPU with HT that does not support 64-bit so it's running an i686 kernel. It does have a Broadcom NIC like an earlier post was suspicious of: 02:08.0 Ethernet controller: Intel Corporation 82562EZ 10/100 Ethernet Controller (rev 02) 02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02) I have upgraded about 8 other servers with no random reboot problems but they are all running on a newer processors with a 64-bit kernel. -- Dave Jones

Removing old kernels
by Frank M. Ramaekers 03 Jun '09

03 Jun '09

I have the following kernels on my /boot: 2.6.18-128.1.6 2.6.18-92.1.18 2.6.18-92.1.22 I'm low on /boot space and need to remove the oldest version. It appears that I cannot use yum to remove since all of the versions are the same (only the release is different). I believe that I can use rpm to remove the old version, but I also need to remove them from the grub.conf. Any other considerations and/or methods? Frank M.

This is what we all *believe* we know (e.g. "5"-current is now "5.3"+updates). However, TUV seems to have had a different opinion st some point in the past, or at least this is what Johnny understood. Read carefully this: http://bugs.centos.org/view.php?id=2481 Excerpts: ============================== we are trying something new to correspond to an upcoming 5.y.z release scheme from upstream. in the scheme, there will be a 5.1.z and 5.2.z tree ... those trees will be available for an extended period of time (5.1 and 5.2 ... each with different updates). ============================== we are not exactly sure how or even when upstream will do this z tree thing ============================== we do not have any intention of doing 5.1.1 or 5.1.2, just 5.1 ... and maintaining it while it is maintained upstream. ============================== Also, we do not plan to - as Johnny has already pointed out - do any 5.1.1 or 5.1.2 or 5.1.3 releases, since again that would be counter productive and leave users with a false sense of security thinking they have the latest patch levels for each machine - when they might not. ============================== So there *should* have existed: * 5.1-only updates issued post-5.2; * 5.1-only and 5.2-only updates issued post-5.3; etc. AFAIK, this never happened. Is the 5.x.z tree concept dead-before-birth?! Thanks, R-C __________________________________________________________________ Looking for the perfect gift?

As per the upstream vendors errata support policy, updates for CentOS-2 ended on May 31, 2009. It is recommended that any system still running CentOS 2 should be upgraded to a more recent version of CentOS to ensure continued security and bug fix support. Upgrade information can be found here http://wiki.centos.org/MigratingTwoToFive More details are available from the RedHat web site at https://rhn.redhat.com/errata/rh21as-errata.html Thank you to everyone who helped make this project possible. The CAOS and CentOS projects, the unnamed upstream vendor and of course, the users who gave it a reason to exist. After 5 years at the helm of CentOS-2, I look forward to working on some new projects both CentOS and elsewhere. This might be the last update announcement I post but it won't be the last time you see my name.

Harware vs Kernel RAID (was Re: External SATA enclosures: SiI3124 and CentOS 5?)

I've read a lot of different reports that suggest at this point in time, kernel software raid is in most cases better than controller raid. The basic argument seems to be that CPU's are fast enough now that the limitation on throughput is the drive itself, and that SATA resolved the bottleneck that PATA caused with kernel raid. The arguments then go on to give numerous examples where a failing hardware raid controller CAUSED data loss, where a raid card died and an identical raid card had to be scrounged from eBay to even read the data on the drives, etc. - problems that apparently don't happen with kernel software raid. The main exception I've seen to using software raid are high availability setups where a separate external unit ($$$) provides the same hard disk to multiple servers. Then the raid can't really be in the kernel but has to be in the hardware. I'd be very interested in hearing opinions on this subject.
