Weird update problem
by Anne Wilson 05 Jan '10

05 Jan '10

For some time now updates on my CentOS box had skipped exiv2. Yesterday I decided to do something about it, so I removed it - together with gwenview, digikam and, IIRC, libexiv2. That sounded reasonable, so I accepted the removal, then re-installed gwenview and digikam, which, of course, pulled in the two exiv2 packages. The version number of exiv2 sounded familiar, but I assumed that it would bring in the best-match version, and continued. This morning, seeing that more updates were announced, I ran update again. To my surprise, exiv2 was skipped, as before. I'm curious as to what could be happening here. Anne -- KDE Community Working Group New to KDE Software? - get help from http://userbase.kde.org

Installing over network
by Slack-Moehrle 05 Jan '10

05 Jan '10

Hi All, I see that sparc.centos.org does not contain any ISO's so that I can install from CD. How does one install over the internet? I have never done it before. I assume use the boot.iso and make sure that I have DHCP turned on so that I get an IP automatically from my router? Any advice? -Jason

Hello all, Can anyone please help out with configuring PAM? I've checked a couple of tutorials online.. though most of them are related to Login though I want to set PAM up for SSH logins...

OT: piped greps with regex
by Mr. X 04 Jan '10

04 Jan '10

List, Happy NY. >From the bash command below, I'm trying to parse out the startsector value: $ sudo file mini_vusb.img mini_vusb.img: x86 boot sector, Microsoft Windows XP MBR, Serial 0x25d84; partition 1: ID=0xe, active, starthead 1, startsector 32, 390496 sectors First try was with grep/egrep but I wanted to capture 'startsector 32' as a group (). Nothing came close to working. Fail 1 Next attempt was with Perl file mini_vusb | perl -lane '$i=0 ;for (@F) {print substr($F[$i+1],0,-1) if ($_ eq "startsector"); $i++}' the above works, but it's too much fire power for the job :) Actually I came up with it in a minute or two once I remembered the special var @F. Success 1 Last effort led to this $ sudo file mini_vusb.img | grep -Po 'startsector\s+\d+'| grep -Po '\d+' 32 I like this best. Is there a way to shorten it up? -- Mark

Tiny webserver to run as root
by RedShift 03 Jan '10

03 Jan '10

Hi all Does anyone have a suggestion for some software, a tiny webserver that is able to run as root and execute CGI scripts? It should be smaller than apache and preferably even smaller than lighttpd. It doesn't need a whole lot of features, it only needs to be able to execute CGI scripts. I have tried a few: nanoweb (which is written in php as well) but has some problems with CGI scripts and when it runs in multi process mode it brings the system load up to exactly 1.00. Nullhttpd, but it's old and unmaintained. Tinyhttpd isn't up for the job as well (kept crashing at times). Thanks, Best regards, Glenn

Setting CDROM parms
by Robert 03 Jan '10

03 Jan '10

My apologies in advance for asking such an elementary question. I called myself searching the Installation Guide and Deployment Guide, with no success. The situation is that I bought a Lite-On ATAPI iHAP122 that will not burn DVDs unless I use hdparm to turn dma off. I bought that drive because it was a rare beige drive. Until I can find a decent DVD burner and/or get a Windows machine put together strictly for doing BIOS updates, running with dma disabled seems to be the best solution. (hdparm -d0 /dev/hdb ) So, my question is, where should I script the command without having to become root each time I wat to burn a DVD? 2.6.18-164.9.1.el5PAE #1 SMP Tue Dec 15 21:41:47 EST 2009 i686 athlon i386 GNU/Linux This is how it always fails: [rj@madeleine ~]$ growisofs -dvd-compat -Z /dev/hdb=/home/rj/KNOPPIX_V6.2DVD-2009-11-18-EN.iso Executing 'builtin_dd if=/home/rj/KNOPPIX_V6.2DVD-2009-11-18-EN.iso of=/dev/hdb obs=32k seek= 0' /dev/hdb: "Current Write Speed" is 16.4x1352KBps. :-[ WRITE@LBA=30h failed with SK=4h/ASC=08h/ACQ=03h]: Input/output error :-( write failed: Input/output error /dev/hdb: flushing cache /dev/hdb: updating RMA /dev/hdb: closing disc [rj@madeleine ~]$

reading -- and editing -- ebooks
by ken 03 Jan '10

03 Jan '10

Last week I bought a couple books, not ebooks. I considered buying the ebook, but don't want to need a special device/appliance to read it. I'd much prefer to read ebooks on the Linux (CentOS) machine I'm already using. Also, I'd like to be able to programmatically convert the ebook into a format I can edit myself, e.g., HTML. I have no experience owning or purchasing ebooks. Could people who have clue me in on how they work and if the above is possible. Thanks much. -- Without music, life would be a mistake. --Friedrich Nietzsche

kickstart and logins.def question
by Kwan Lowe 03 Jan '10

03 Jan '10

Hello all: Happy New Year to everyone and thank you for all the knowledge this past year. I have a hopefully simple question about kickstart. In the authconfig section I can enable ldap, credential caching, etc.. Using the GUI tool there's an option to create the user home directories on first login. The docs don't show a similar option for authconfig in kickstart. For now I'm using a sed script in the %post section of the kickstart to replace the entry in /etc/login.defs, but was curious if there is a standard method via a system utility to change this option.

Sparc?
by Slack-Moehrle 02 Jan '10

02 Jan '10

My 12 year old wants to learn more about servers and has memorized a lot of commands like ls, chmod, du, etc. He wants to have his own domain and server on the web and I have enough Static IP's, so why not foster this interest. I have an old ultra sparc 5. Are there any CentOS versions that support Sparc? Or recommendations? I know OpenBSD does, but I am more versed in Solaris and versions like Slackware or CentOS or Ubuntu. He also says that ZFS rules all and is pissed Apple did not adopt it. Kids will be kids! -Jason

chroot problem.
by Frank M. Ramaekers 02 Jan '10

02 Jan '10

First, I'm trying to following along on a document on "SecurityFocus" on "Securing MySQL: step-by-step". I'm on step 3.8 "Test the configuration". I have my CHROOT directory structure setup and the chrootuid is failing (haven't figured that one out, yet). So, I simply tried a 'chroot /chroot/mysql' and got: chroot: cannot run command `/bin/bash': No such file or directory I realized that the documentation didn't cover this so I simply: cp -a /bin/bash /chroot/mysql/bin I'm still getting the same error message when I try 'chroot /chroot/mysql': # chroot /chroot/mysql chroot: cannot run command `/bin/bash': No such file or directory It's there, I'm not sure what the problem is: # ls -l /bin/bash -rwxr-xr-x 1 root root 859120 Oct 24 2008 /bin/bash # ls -l /chroot/mysql/bin/bash -rwxr-xr-x 1 root root 859120 Oct 24 2008 /chroot/mysql/bin/bash (I'm performing this as root, since the mysql userid cannot login.)

need to free space on a root partition.
by Yan Yu 02 Jan '10

02 Jan '10

Hello, there, Happy new year everyone! I am puzzled here. Could some expert help me shed some light on this? this may not be a centos specific Q.. i have a linux machine. and the root partition (/) is full.. so I moved a dir from /data to /var (/var is on a different partition), and created a link from /data/fa to /var/xyz, the files under /var/xyz is about 8G, du /var/fa 8701248 /var/fa so I thought this should free some space for me, but when I used df, it gave me similar results before and after the move.. and my rpm installation would fail due to the lack of space.. Filesystem 1K-blocks Used Available Use% Mounted on /dev/cciss/c0d0p6 15235040 15232452 0 100% / /dev/cciss/c0d0p8 other partitions have free space.... I was confused on why moving a 8G file to another partition did not free some space for me? and I did see that the disk usage for the destination partition/disk increases after the move.. any pointer is appreciated! yan

which program/command (perl, vi, or sed) is better

Hi I have apache log file around 7.6G and record half year Which program/command (perl, vi, or sed) is better to extract the data by date? and finally I can remove that big file and still keep the record.

Lost mdadm.conf

Hi, I lost my mdadm.conf (and /proc/mdadm shows nothing useful) and I'd like to mount the filesystem again. So I've booted using rescue but I was wondering if I can do a command like this safely (i.e without losing the data previously stored). mdadm -C /dev/md0 --level=raid0 --raid-devices=2 /dev/sda1 /dev/sdb1 Where of course the raid devices and the /dev/x are the correct ones

Hey all, I am getting a number of incoming emails flagged as spam this morning. Here's why: X-Spam-Level: ***** X-Spam-Status: Yes, score=5.2 required=5.0 tests=FH_DATE_PAST_20XX, SUBJ_ALL_CAPS autolearn=no version=3.2.5 X-Spam-Report: * 3.4 FH_DATE_PAST_20XX The date is grossly in the future. The date of 2010 in the emails is correct. I have typed "sa-update" and restarted, to no avail.

one server handled sendmail added two more servers messes things up
by Jerry Geis 01 Jan '10

01 Jan '10

Hi all, I had one server running centos 4.7 i686 everything was fine with incoming mail. I now added two more servers centos 5.4 x86_64 and gave them machine names all part of the same domain as machine 1. I noticed that incoming emails are being round robined to all three machines. At this time I really just want the one original machine to handle my incoming email... The other two new machines are for other purposes. How do I tell the two new machines that all incoming email send to machine 1. Is there an easy way to do that? At this point I just turned off the two new machines and all mail is coming into the original machine just like before. Thanks, Jerry

missing module dir?
by Michael Klinosky 01 Jan '10

01 Jan '10

I'm teaching myself about ethernet cards, and found a TLDP page. I have CentOS 5.3. In this section: http://tldp.org/HOWTO/Ethernet-HOWTO-2.html#ss2.4 in the 'Driver as module' subsection, regarding PCI cards, it states that there should be a directory "/lib/modules/`uname -r`/net" [mykolas@sr1220 ~]$ uname -r 2.6.18-128.1.16.el5 [mykolas@sr1220 2.6.18-128.1.16.el5]$ pwd /lib/modules/2.6.18-128.1.16.el5 [mykolas@sr1220 2.6.18-128.1.16.el5]$ ls build modules.alias modules.ieee1394map modules.ofmap modules.symbols updates extra modules.ccwmap modules.inputmap modules.pcimap modules.usbmap weak-updates kernel modules.dep modules.isapnpmap modules.seriomap source There's no 'net' directory. I am guessing that the NIC drivers are modules (and not compiled into the kernel) - am I wrong? Or, where are the modules?

[OT] CAT5 IP-capable rackmount KVM units?
by Thomas Harold 31 Dec '09

31 Dec '09

Rather off-topic, but I'm looking for IP-based KVMs (~16 ports) that can handle both PS/2 and USB hookups on the server side. All of the answers over at Slashdot are a few years out of date and it looks like prices on KVM head units have dropped a bit over the years. Some of the older units only worked with Windows, Internet Explorer and ActiveX. Others like the ATEN KH1516i supposedly use Java and are far better from a cross-platform point of view. I'm on the fence about the CAT5 cables over the more traditional style, it seems like the CAT5 cable system would give a lot more flexibility in dealing with USB vs PS/2 servers (or even serial only?). The bigger advantage with the CAT5 stuff seems to be fewer length limitations and less space used in the rack for the head unit. I'm guessing that the CAT5 adapters are going to be proprietary?

Find reason for heavy load
by Noob Centos Admin 31 Dec '09

31 Dec '09

My Centos 5 server has seen the average load jumped through the roof recently despite having no major additional clients placed on it. Previously, I was looking at an average of less than 0.6 load, I had a monitoring script that sends an email warning me if the current load stayed above 0.6 for more than 2 minutes. This script used to trigger perhaps once an hour during peak periods. Even so, I seldom see numbers higher than 1.x On 4th Dec, somebody from an Indian IP range started hammering my SMTP service, attempting to use it as an open relay. Naturally that didn't work and only end up budging my typical 400KB daily log report into 2MB~4MB affairs. After observing a few days to determine the IP range, I started blocking the Indian subnet with apf. Initially I had problems with getting apf to wok properly but after a couple of days managed to get the block working and my daily log went back down to expected size when all those connection attempts disappear from exim's log. Now this is when my server load started to shoot through the roof with figures like 8.64 5.90 3.62 being reported by my monitoring script, triggering so often. I had to raise my threshold to 1.6 to keep my own script from spamming myself. I've tried changing several things on the server, since initially it seems like the high load may be due to I/O wait. So I turning off non-essential services like OpenNMS to see if that had any effect. I also turned off apf and inserted rules manually into iptables to reduce the number of iptable rules the system has to process. All that doesn't seem to help much, I'm still getting consistent server loads in the 2.x to 3.x range almost all the time. The problem is using top, none of my processes are showing abnormal CPU%, most are well under 5%, manually adding them up doesn't equate the 200% to 300% the load figures of 2.x and 3.x are indicating. Even top's own summary says CPU % is in the 20~30% range, what's worrying is the System% is also in the same range. I have no idea what is "system" doing since it appears that anything running inside the kernel is lumped under "system". Or why even totalling both % up, I would expect 50~60% to translate to the expected load of 0.5~0.6 yet system load stats is 5x what's expected. I've installed utilities like dstat to try to see if I can figure out which process is making the system calls that is clogging up the server but either I don't understand it or it's not the right tool. So I'll appreciate some advice on how/what should I do next to identify the cause. Thanks in advance!

Aide questions
by Steve Campbell 31 Dec '09

31 Dec '09

I've got aide aide-0.13.1-4.el5 running on a server, and aide aide-0.13.1-2.0.4.el5 running on a similar server. There appears to have been a change in the way base directories are being monitored in the two versions. Both servers are running logical volumes, but it seems to not matter as I'm running aide on a server without logical volumes and the problem still shows up. Now the problem.... On the server with the newer aide, it reports MTime and CTime changes in some of the base directories such as: Directory: /root Mtime : 2009-12-18 09:14:02 , 2009-12-24 12:20:53 Ctime : 2009-12-18 09:14:02 , 2009-12-24 12:20:53 Directory: /usr/bin Mtime : 2009-12-18 00:04:20 , 2009-12-31 00:05:08 Ctime : 2009-12-18 00:04:20 , 2009-12-31 00:05:08 The older version of aide doesn't do this. Both aide.conf files are identical. I've tried entries in the conf file like the following to avoid this, but it seems I shouldn't have to do this: /usr/bin$ DIR where I've redefined DIR to not include "m" and "c". I still get reports of files below /usr/bin, but this avoids the changes to the directory itself everyday. Does anyone have a clue how to avoid this any other way, and maybe if aide is doing this differently now (and why)? It's not a big deal, but I'm kinda believing I'm not doing it the right way. Thanks steve campbell

VirtualBox and CentOS
by Lars Hecking 31 Dec '09

31 Dec '09

I recently doownloaded and installed the latest RHEL5 rpm from the VirtualBox web site. While it generally works very well, I have been unable to get USB access to work on the guest. This seems to be a very common problem. Many references to it turn up in a web search, but I have not found a solution that works on CentOS 5. I got no response on the vbox-users mailing list either. Can anyone here help? Among the things I tried were various /sys and /proc/bus/usb related fstab and rc.sysinit changes. Drew a total blank on this one ...

autofs problems
by Mag Gam 30 Dec '09

30 Dec '09

We have about 800 CentOS 5.2 servers and our university. We use NFS being served from over 10 NetApp frames. We use autofs for to mount up our partitions. There have been times where we can't cd into the directory. It says the directory does not exist. On some servers it works but on others it does not. Typically we restart amd and autofs to resolve this issue. But sometimes it does not even work. A reboot fixes the problem. I am wondering if anyone knows any tricks to check if autofs is working properly on the system and also what I should do in a situation like this. TIA

OT: What are the 2 openssl commands I need to use?
by Lanny Marcus 30 Dec '09

30 Dec '09

I looked on the openssl man page but am too dense with commands to understand what I need to do..... Ran into problems generating a key and CSR for SSL, because the web site is on a server with an old Ensim Control Panel. Please someone knowledgeable, give me the openssl commands I need to use, after I ssh into the web site, to generate a 2048 bit key and csr. TIA and Happy New Year! "I believe the issue you are having is due to the size of the encryption key. The ensim control panel generates a 1024 bit key, where the certificate you got was 2048 bits. What you need to do is generate a 2048 bit key and csr on your domain. You would need to login in to your domain through ssh and generate the files from the command line."

You would Thank you, to everyone who responded! In the end, it wasn't necessary for me to use the openssl command, as the man in OLM Tech Support had suggested to me earlier today. Eddy at StartCom (StartSSL) gave me the commands, to check the Modulus of the ssl.key and ssl.crt files, which I'd made this morning, after running into the problem and confusion, with the 1024 bit CSR from the old Ensim Control Panel and the 2048 bit files Start SSL created, and the Modulus were identical. I was able to Import them, successfully, with the Ensim Control Panel. So, after OLM restarts Apache, the encryption should work. This was a learning experience for me and I will reread this thread and try to learn more from it. Happy New Year and again, thank you, to everyone in this list who shares their time and expertise. Deeply appreciated!

I'm looking for how I can integrate it into the system so that the system will shut down either after the UPS power is low enough or a timed event after the power is out will automatically shutdown. Would also like it to be smart enough to stop the shut down process if power is restored before the shutdown starts. Anyone have any recommendation for this setup?
