logrotate.d - reload vs restart
by Frank Cox 28 Dec '10

28 Dec '10

Looking at some of the stuff in /etc/logrotate.d, I see entries like this in some of the configuration files: postrotate /sbin/service privoxy reload 2> /dev/null || true >From the commandline, that doesn't work: # /sbin/service privoxy reload 2> /dev/null || true Usage: /etc/init.d/privoxy {start|stop|restart} Changing reload to restart does work: ]# /sbin/service privoxy restart 2> /dev/null || true Stopping Privoxy, OK. Starting Privoxy, OK. I find "reload" in the httpd logrotate file as well: postrotate /sbin/service httpd reload > /dev/null 2>/dev/null || true What am I failing to understand? -- MELVILLE THEATRE ~ Melville Sask ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER!

Kickstart Network Configuration Issues
by Daniel Theisen 28 Dec '10

28 Dec '10

Hello all, I've been struggling with an issue with my kickstart configuration for a while now. My kickstart files are stored within the initrd image. What I would like to do here, is when the kickstart first starts up, I want it to grab a DHCP address (it does at the moment) so it can grab all of the necessary installation data off the net. Then, at some point _IN_ the install process, I'd like to have it query for manually input network settings. Here is my current kickstart script: auth --useshadow --enablemd5 bootloader --location=mbr zerombr clearpart --all --initlabel text firewall --enabled --port=22:tcp firstboot --disable keyboard us lang en_US logging --level=info url --url=http://mirror.nexcess.net/CentOS/5.5/os/x86_64/ reboot --eject rootpw --iscrypted xx selinux --enforcing skipx timezone --isUtc America/Detroit install part /boot --bytes-per-inode=4096 --fstype="ext3" --size=512 --ondisk=sda part swap --bytes-per-inode=4096 --fstype="swap" --size=2048 --ondisk=sda part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sda part /backup --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sdb network --bootproto=dhcp --device=eth0 %packages --nobase @core system-config-network-tui %post echo "nameserver 4.2.2.1" > /etc/resolv.conf echo "nameserver 8.8.8.8" >> /etc/resolv.conf # write netconfig script cat << EOF > /bin/netconfig #!/bin/bash # check if user is root if [[ \$EUID -ne 0 ]]; then echo "This script must be run as root" 1>&2 exit 1 fi # run system-config-network-tui /usr/sbin/system-config-network-tui # set variables eth0f="/etc/sysconfig/network-scripts/ifcfg-eth0" eth1f="/etc/sysconfig/network-scripts/ifcfg-eth1" netcfg="/etc/sysconfig/network" # turn on eth1 if it has an address, remove gateway.. shouldn't be set here # anyways if [ -f "\$eth1f" ]; then if grep -q "IPADDR" \$eth1f; then sed -i 's/ONBOOT=no/ONBOOT=yes/' \$eth1f sed -i '/^GATEWAY/d' \$eth1f sed -i '/^HOTPLUG/d' \$eth1f fi fi # move gateway from ifcfg-eth0 to /etc/sysconfig/network if [ -f "\$eth0f" ]; then e0gw=\$(grep "GATEWAY" \$eth0f) sed -i '/^GATEWAY/d' \$eth0f # check to see if the gateway is already set. if it is, delete it first if ! grep -q "GATEWAY" /etc/sysconfig/network; then echo \$e0gw >> \$netcfg else sed -i '/^GATEWAY/d' \$netcfg echo \$e0gw >> \$netcfg fi fi EOF chmod +x /bin/netconfig At the moment, I have a not-so-elegant script written to the server to be run manually after install. I began using system-config-network-tui vanilla, but realized it had some differences from the network configuration tool in anaconda (net.c?) I tried my best to correct those differences with my netconfig script. I've already tried running system-config-network-tui in the %post section, but it doesn't seem to work. If anyone has had experience in dealing with a scenario such as this, any help would be greatly appreciated. Thanks, Daniel Theisen <dtheisen(a)nexcess.net>

Server unresponsive until reboot, memory exhausted
by james 28 Dec '10

28 Dec '10

I'm having an issue with an apache web server running the latest CentOS5 kernel (this issue is not new to the kernel). After a few days/weeks of running the server will become unresponsive and will require a physical reboot in order to come back online. The system is so unresponsive when the issue occurs that login at console is not even possible. I have atop installed and have looked back before the crash to see what happened process wise and I can see the http starts using a lot of memory and CPU usage. The vmcommit jumps from 1.8 GB to 4.8GB in a matter of a few minutes. The VSIZE of the httpd process jumps from 8.1GB to 36.9GB. So apache is doing something -- but how can I get historical data for this? I also see that paging is very active, probably why the server is unresponsive. I have looked through the apache logs and system logs and there is nothing obvious that is consuming all that memory. I know of the server-status module for apache but that is only useful if you can get to the server during the crash (I can't) and doesn't have any historical data. The issue occurs seemingly randomly, last time in the middle of the night with little or no user traffic. James

by Frank Even 27 Dec '10

27 Dec '10

We just upgraded Cent from 5.3 to 5.5 on a bunch of servers with little to no issues (kudos to you guys) except on a few servers where it appears we are having a problem w/ the Tomcat upgrade. Previously our application server was working fine under 5.3 with Tomcat/Java installed as such: java-1.4.2-gcj-compat-1.4.2.0-40jpp.115 java-1.6.0-openjdk-1.6.0.0-0.30.b09.el5 java-1.6.0-openjdk-devel-1.6.0.0-0.30.b09.el5 java-sun-jdbc-stdext-2.0.1-1mamba java-sun-jdbc-stdext-javadoc-2.0.1-1mamba tomcat5-5.5.23-0jpp.7.el5_2.1 tomcat5-common-lib-5.5.23-0jpp.7.el5_2.1 tomcat5-jasper-5.5.23-0jpp.7.el5_2.1 tomcat5-jsp-2.0-api-5.5.23-0jpp.7.el5_2.1 tomcat5-server-lib-5.5.23-0jpp.7.el5_2.1 tomcat5-servlet-2.4-api-5.5.23-0jpp.7.el5_2.1 Now that we've run the full update, we have this installed: java-1.4.2-gcj-compat-1.4.2.0-40jpp.115 java-1.6.0-openjdk-1.6.0.0-1.16.b17.el5 java-1.6.0-openjdk-devel-1.6.0.0-1.16.b17.el5 java-sun-jdbc-stdext-2.0.1-1mamba java-sun-jdbc-stdext-javadoc-2.0.1-1mamba tomcat5-5.5.23-0jpp.11.el5_5 tomcat5-common-lib-5.5.23-0jpp.11.el5_5 tomcat5-jasper-5.5.23-0jpp.11.el5_5 tomcat5-jsp-2.0-api-5.5.23-0jpp.11.el5_5 tomcat5-server-lib-5.5.23-0jpp.11.el5_5 tomcat5-servlet-2.4-api-5.5.23-0jpp.11.el5_5 tzdata-java-2010l-1.el5 I don't see any significant changes.

Moving from Fedora -- Advice??
by Beartooth 27 Dec '10

27 Dec '10

I'm running Fedora14 on all machines, including my wife's -- and I'm the nearest (distant) thing there is to tech support. She's far more likely to outlive me than I her; so I want to install something requiring a lot less maintenance on her machine, so that she'll have it and be used to it, years ahead of need. I'm thinking CentOS 6, whenever it's ready, is probably my best choice. Any thoughts?

hi all, I will be migrating my mail server from centos 4.8 to 6 when its released. Basically its just a number of users with their passwords. Their mail is downloaded to their clients and not stored on the server. What is the most sensible or correct way to migrate ALL the users to the new system? Way in the past is was just perhaps copy the /etc/passwd file but I know thats not the case anymore. how do I easily recreate their account names etc... on the new machine. Thanks, for any advice.

I/O size distribution?

Hello I have read that under Solaris one can use DTrace to get I/O request size distribution on a global scale (also on a per process/pid basis).

two cents or not two cents
by Sean 23 Dec '10

23 Dec '10

Hello Producers "Longevity of Support" is an attractive drawcard for CentOS if it means the exact opposite of Fedora's "short support cycle" that does not provide updating of infrastructural libraries for very long, libraries which newer versions of applications (like Firefox, Thunderbird, Opera etc) depend on and which wont install unless the libraries are also newer versions? But is that what it means -- ie that those infrastructural libraries (libpango, libcairo etc) are continuously updateable to fairly recent versions? If so, the problem is in reconciling that meaning with the reputation of CentOS to only support older versions of applications (eg Firefox-1.5, Thunderbird-1.0 etc). It does reconcile, of course, if the implications are merely that the CentOS user must compile and install the later versions of such applications from source, rather than having the luxury of pre-packaged binaries. It doesn't reconcile if there is some other critical reason why newer such applications just wont install. But which? I ask here because the profusion of vague mission statements and 'target-enduser-profile' claims that litter the internet re '*nix distros' seldom actually address those real issues. And hopefully someone can enlighten. My complex production & developement desktop takes months to fully port to a new OS (or OS-version), so OS updates to get library updates (ala Fedora philosophy) becomes increasingly untenable. Then there is a further question, I'm afraid. Since CentOS also does specifically target the profile of a so-called 'enterprise/server-user' what does that actually entail. Does it mean concrete security strictures which bolt down non-'root' users or does it merely mean the availability of SELinux (but which can be turned OFF)? For instance, (with SELinux OFF), can a user still: (a) su root via Kterm anytime? (b) Access services-admin anytime via Menu+Pam to control printers, modems, daemons etc? (c) compile (d) have 6 to 8 desktops running (e) call up 'konquerorsu.desktop' (root-konqueror with embedded root-Kterm) (f) have normal cron scheduling .......................................................... maybe more, but that's a start. Thanks for listening. Sean

changing background image
by Jerry Geis 23 Dec '10

23 Dec '10

I'm running centos 5.5 - 64 on Nvidia hardware. I am getting video from totem mixed in with my background image when I stop totem. If I change the background back to the default it does not seem to happen. However, as soon as I change the background to something else like ladybug.jpg and run totem fullscreen, then ask totem to quit with "totem --quit" the last video image is mixed in with my background. I did the standard (I think) way to change the background image: /usr/bin/gconftool-2 -t string --set /desktop/gnome/background/picture_filename "/usr/share/backgrounds/images/ladybug.jpg" su silentm -c "/usr/bin/gconftool-2 -t string --set /desktop/gnome/background/picture_filename '/usr/share/backgrounds/images/ladybug.jpg'" Is there something else I might be missing so the "still" of the video is not mixed in with my background? Thanks, Jerry

sendmail / logwatch relaying issue - driving me crazy
by Götz Reinicke - IT-Koordinator 23 Dec '10

23 Dec '10

Hallo, *<:-) may be I'm to tired to see the solution, maybe someone can give me a hint? I do have a couple of servers, sending the daily logwatch report to a central support email account. Some servers do have DNS A and CNAME records. On my mailserver relaying for the servers is allowed. Only one server drives me crazy, getting user unknown or releaying denied messages. Any idea, how to debug this issue? I'd be glad to fix this as a christmas gift. I could provide logmessages of course. Thanks and best regards Götz -- Götz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax +49 7141 969 55 420 E-Mail goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg GmbH Akademiehof 10 71638 Ludwigsburg www.filmakademie.de Eintragung Amtsgericht Stuttgart HRB 205016 Vorsitzende des Aufsichtsrats: Prof. Dr. Claudia Hübner Geschäftsführer: Prof. Thomas Schadt

Aravindh, Tell us a little bit about your current server hardware, are your NICs showing using ifconfig, what about your gateway sing route. It would be good to know a little bit about your current configuration, including if you are using IPv6. Please elaborate so we can help you further.

Text Proccessing script - advice?

Hello, I have a log file with the following input: X , ID , Date, Time, Y 01,01368,2010-12-02,09:07:00,Pass 01,01368,2010-12-02,10:54:00,Pass 01,01368,2010-12-02,13:07:04,Pass 01,01368,2010-12-02,18:54:01,Pass 01,01368,2010-12-03,09:02:00,Pass 01,01368,2010-12-03,13:53:00,Pass 01,01368,2010-12-03,16:07:00,Pass My goal is to get the number of times ID has a TIME that's after 09:00:00 each DATE. That would give me two output. one is the number of days ID has been late, and secondly, the day and time this ID has been late . I've started as such: sort -t ',' -k 3,3 -k 4,4 file.log # this will sort the file according to the DATE field as well as the Time fileld. I'm stuck for the last 30 min to find a way to get the first line of each day (logically it'll be the earliest as i've sorted by date/time previously) once i know how to do this, i'll be able to compare time and proceed.. Can any one help ? i looked into sort - u and uniq -f3 though i didnt get far with it..

Cloud demographics
by Christopher Chan 21 Dec '10

21 Dec '10

Please turn off troll detectors. Especially those with big automatic hammers. http://thecloudmarket.com/stats#/by_platform_definition Anybody 'extra' bandwidth from the 'Cloud'? Ubuntu installations currently trumps the combined numbers of Centos, Fedora and RHEL (not that using Centos/Fedora/RHEL guarantees secure installations) installations and I just wondered on that aspect. On another note, I wonder how big a change will take place in the demographics when Centos 6 'hits the streets'.

Routing issue between 2 LANs
by Jose Maria Terry Jimenez 20 Dec '10

20 Dec '10

Hello All First, sorry by my poor english, hope you understand me :-) I have a problem, i don't understand or don't know how to solve I need to interconnect 2 networks with different numbers. One is 192.168.236.0/24 the other 192.168.1.0/24. Mainly i need to access services in the 236. from the 1. one. I have a CentOS 5.5 machine with 2 nics each one configured to work in one of the nets. The CentOS also uses a router for Internet access that is 192.168.1.1. 192.168.1.0/24 >-----192.168.1.100--[CentOS Machine]--192.168.236.74 --------< 192.168.236.0/24 So, i enable forwarding in the CentOS box echo '1' > /proc/sys/net/ipv4/ip_forward And in one machine of the 1. network (this is Fedora14) I add the route: route add -net 192.168.236.0 netmask 255.255.255.0 gw 192.168.1.100 dev eth0 Since this moment i can ping or access (ssh/http) another CentOS machine in the 236 network ping 192.168.236.74 PING 192.168.236.74 (192.168.236.74) 56(84) bytes of data. 64 bytes from 192.168.236.74: icmp_req=1 ttl=64 time=0.281 ms But can't access or ping other machines (NOT Linux ones), ie, printers, Win servers, etc... Also tried adding: route add 192.168.1.100 eth0 before the route add -net, but no efect. This fails even if i flush IPTables. In the CentOS box that replies, i did nothing, it 'just' works. Can anyone tell what is happening / help me with this? Something to do missing in the CentOS router that joins the networks? Best,

httpd log weirdness
by Jason T. Slack-Moehrle 20 Dec '10

20 Dec '10

Hi All, I setup a new Centos 5.5 bod and it will be running a site for me. Apache is running and daily I get e-mailed a log from the box. The log today said: --------------------- httpd Begin ------------------------ Requests with error response codes 404 Not Found http://www.cablecarmuseum.org/Car42.jpg: 1 Time(s) ---------------------- httpd End ------------------------- But that is not my domain at all. How would this entry show up in my log? I ping'd the domain above and it does not resolve to the IP of the box or any of my IP's. Can anyone shed some light on this? Best, -Jason

How to strip out the title bar from xterm windows on CentOS 5 GNOME?
by Aleksey Tsalolikhin 20 Dec '10

20 Dec '10

Hi. Running CentOS 5 with the default GNOME desktop. Is it possible to configure xterm windows not to have title bars to get the most out of the available screenspace? I've tried to look this up but mostly find reference how to change the content of the title bar; I want to remove it completely. Found a reference to Compiz but the version available through CentOS seems old (0.0.13 compared to the current around 0.8 or 0.9) and having a double zero version number, I was afraid to use it. Best, -at

Building packages using RPMBUILD
by Keith Roberts 19 Dec '10

19 Dec '10

I have been following the MaximumRPM guide from here: http://www.rpm.org/max-rpm-snapshot/index.html and it seems a bit dated, but still very good (if fact the best all round documentation I have found so far) on using RPM package manager, and how to build rpm packages. The guide tells me to use the original paths, yet Centos wiki says otherwise. [rpmbuilder@karsites sox]$ rpm -iv ./sox-12.18.1-1.src.rpm error: cannot write to %sourcedir /usr/src/redhat/SOURCES Is there a package I need to install and run to set things up corectly? I have created a user called 'rpmbuilder' under my home dir, and created the rpmbuild dirs under that. So what build dir shall I go for? Kind Regards, Keith Roberts -- In theory, theory and practice are the same; in practice they are not. This email was sent from my laptop with Centos 5.5

how to install Linux on an IBM xserver 335 server without graphics card?
by Rudi Ahlers 19 Dec '10

19 Dec '10

Hi All, I recently got some IBM Xseries 335 servers 2nd hand, and noticed they don't have any graphics card. Some google searched indicate they only have an uplink port, which you could connect to another (other model) IBM server and use that as the head node. But, I don't have one available. It has 2x GB NIC's, and what looks like a management port, but I can't figure out how to use it. SSH & HTTP connections to it was futile. OR, it was assigned a dedicated IP, on a different subnet than ours but it's not written down anywhere so I don't know what IP to connect to. Does anyone know how to get Linux installed onto these devices? We have a PXE server in the office which I generally use for this setting up servers over the LAN, but they always have a VGA port. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Best way to set up for PHP websites
by Ruslan Sivak 19 Dec '10

19 Dec '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am looking to set up a CentOS server for hosting a high traffic PHP site (specifically Drupal 6). I am trying to figure out what's the best way of setting up PHP. The standard mod_php seems to not be a good solution, as it requires apache to be in the prefork configuration, due to PHP not being thread safe. Something like mod_fcgi seems to be the way to go, but I can't seem to find a good guide on setting it up. I installed Zend Server, but seems like they are only supporting FastCGI for Apache on Windows, and only mod_php on Linux. Their admin control panel is using lighttpd and mod_fcgi on Linux. I getting it to work with Apache, but am having issues with the missing mysqli libraries. Is it recommended to use mod_fcgi on CentOS? Is there a way to get it to work with Zend Server? If not, should I try to get things working with lighttpd? I'm not sure how easy it would be to set up a config to work with Drupal.
