clients obtaining dhcp addys slowly
by aurfalien＠gmail.com 11 May '10

11 May '10

Hi all, This is unusual for me to observe. I've a dhcp server running on Centos 5.3 and it takes a while to answer clients asking for an address. This is playing some havoc with certain scripts at startup not fully working because of the address delay. I've even used a dhcp helper address type function in my Juniper router but nothing has changed. Any ideas?

mail server best practices question
by Coert 11 May '10

11 May '10

Hello all, About a year ago I set up a mail server on CentOS using this howto: http://wanderingbarque.com/howtos/mailserver/mailserver.html I managed to add amavisd-new with clamav and spamassassin. It runs very well, but it runs on CentOS 5.2, and if I try to upgrade, amavisd-new and clamav break. we are now also at the point where a backup mx will need to be implemented. If necessary I am willing to implement a new mail server and a new backup mx. What I would like to know is what solution you guys would recommend for the mail server and the backup MX? Any pointers would be greatly appreciated. Regards, Coert

How can I filter out the distinct records with number of occurances less than a pre-determined threshold?Can you please show my the power of CentOS in manipulating text files? Thank you

tracing the source of a sector error from smartd

I'm not used to using smartd, but have a new set of systems that don't have any sort of RAID on them, so I enabled smartd (18 systems 4 SATA drives each). Running CentOS 5.4 64-bit ..

which gcc package?
by Michael Klinosky 09 May '10

09 May '10

Hello. I tried to compile a program (plugger), but I don't have *any* sort of compiler installed. This is on Cent5.3. So, I used Package Manager, concentrating on gcc. But, it seems that I have a choice, thus: gcc-4.1.2-46.el5.i386 gcc-4.1.2-46.el5_4.1.i386 gcc-4.1.2-46.el5_4.2.i386 gcc-c++-4.1.2-46.el5.i386 gcc-c++-4.1.2-46.el5_4.1.i386 gcc-c++-4.1.2-46.el5_4.2.i386 ... along with some others (Fortran, Ada, Java, and Obj-C). I'm thinking that I need only 1 'flavor' (say, gcc-4.1.2-46.el5.i386 and gcc-c++-4.1.2-46.el5.i386) - correct? I tried a google.com/linux search - the only link that seemed helpful was http://gcc.gnu.org/ -- where I found only this: "The core distribution includes the C language front end as well as the shared components." I have no clue which package would be the FE, and what the shared components are. Perhaps 1 of those packages is the core?

Apache Tomcat/5.5.23
by testwreq wreq 07 May '10

07 May '10

I have a new instllation of tomcat on centos. My $CATALINA_HOME is /usr/share/tomcat5 and tomcat is running. http://localhost:8080 brings up the tomcat page & one of the option is "Administration". I would like to use this web interface and even give some of the test webapp users ability to restart tomcat. According to the home page, users are defined in $CATALINA_HOME/conf/tomcat-users.xml. Currently my file has the following content more tomcat-users.xml <?xml version='1.0' encoding='utf-8'?> <tomcat-users> <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="tomcat" roles="tomcat"/> <user username="both" password="tomcat" roles="tomcat,role1"/> <user username="role1" password="tomcat" roles="role1"/> </tomcat-users> I tried logging to the administration web interface with tomcat/tomcat but it did not work. Can anyone guide to configure this file? I am very new to tomcat. Thank you.

installing gtkmm
by Ming-ching Chiu 07 May '10

Hi, I've been building a gtkmm project on ubuntu and things run smoothly. Now i have to move the project to CentOS 5.4. I set up rpm forge and installed gtkmm. Turns out that the package on rpmforge is too old that my project doesn't compile. I wonder if there is other way to get newer version of gtkmm and all its dependencies instead of manually install them? -best, Ming-ching

Aide error "Caught SIGBUS/SEGV"
by Bowie Bailey 07 May '10

07 May '10

One of my servers has recently started giving an error every time I run "aide --check". I ran it manually twice today with the same results. The second time, I added the -V flag, but that didn't give me anything useful. The system is currently running CentOS 5.3. Nothing on the system has changed recently (that I am aware of). The Aide database hasn't been updated in a few months. This is the error I am seeing: Caught SIGBUS/SEGV while mmapping. File was truncated while aide was running? Caught SIGBUS/SEGV. Exiting I tried Googling for it, but didn't find anything helpful. Any ideas? -- Bowie

Resolving dependencies from the command-line
by Marco Shaw 06 May '10

06 May '10

CenOS 5.4 x64 I'm stuck at the command-line. I'm only familiar with the RPM command, but AFAIK, that cannot automatically resolve any dependencies when installing packages. Is there a command-line utility that I can force to automatically install all the dependencies for a particular package? I seem to remember a new UI was added recently that could, but I have to complete this from a prompt. Marco

Installing a CentOS based distro with Raid driver - Citrix XenServer
by Georghy 05 May '10

05 May '10

Hi everyone, I'm trying to install a XenServer on a server (ref:S5000PAL) http://www.intel.com/products/server/motherboards/s5000pal/s5000pal-overvie… The installation failed because of lack of Raid driver, I found this out because I tried to install XenServer without raid and it worked great. I tried so many drivers, I don't know what to do I tried also this trick : http://forums.citrix.com/thread.jspa?messageID=1456872&#1456872 with this : http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18570&lang=f… driver, but it didn't work (I use the SATA Raid controler not the SAS, so it seems that I have to find the good driver for ESB2 but I'm not sure and it uses megasr driver) Anyone as a clue ? PS : I posted on Citrix forum but nobody's answering, if someone here has a clue I'm greatful to him -- Cordialement, / Greetings, Georghy FUSCO

heartbeat package in extras trouble with 5.4
by Baird, Josh 05 May '10

05 May '10

I just recently upgraded a box from i386 5.3 -> 5.4. The box has heartbeat packages installed from "extras:" heartbeat-pils-2.1.3-3.el5.centos heartbeat-stonith-2.1.3-3.el5.centos heartbeat-devel-2.1.3-3.el5.centos heartbeat-2.1.3-3.el5.centos The heartbeat daemon no longer starts.. the init script reports a success, as well as the logs: May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Enabling logging daemon May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: logfile and debug file are those specified in logd config file (default /etc/logd.cf) May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Version 2 support: false May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: WARN: logd is enabled but logfile/debugfile is still configured in ha.cf May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: ************************** May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Configuration validated.

When I run the daemon interactively without the init script, the following error appears: heartbeat[8818]: 2010/05/04_22:23:37 ERROR: Cannot shmget for process status: Invalid argument This may suggest that some libs on the system may have been upgraded and heartbeat is trying to use the old ones? Does anyone have any suggestions on how to get heartbeat working again? Thanks, Josh

dhclient.conf being ignored!
by Todd Denniston 05 May '10

05 May '10

It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of ifup-eth other options don't seem to be able to be passed to dhclient. I tried placing supersede ntp-servers into dhclient-up-hooks, but that also seems to be ignored, and my google fu seems to be failing on how to build dhclient-enter-hooks for the purpose (if that would even help). anyone got better suggestions than: a) mod /etc/sysconfig/network-scripts/ifup-eth to build /etc/dhclient-$(DEVICE).conf combining the options I want. b) brute forcing things with `chattr +i /etc/ntp.conf` -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter

nfs4 help needed
by Anne Wilson 04 May '10

04 May '10

Fedora 13 is using nfs4, and there is a problem in opening files requiring OpenOffice if accessed over an nfs3 mount, so it's time to change. I found a couple of tutorials, and got it *almost* working correctly. This is where I need help. Logwatch tells me /nfs4exports/Data1 and /Data1 have same filehandle for *,192.168.0.0/24,192.168.0.0/255.255.255.0, using first The tutorial I was following suggested making a root connection as ro, then the data connections as rw, so I have /nfs4exports 192.168.0.0/24 (ro,sync,insecure,root_squash,no_subtree_check,fsid=0) /nfs4exports/Data1 192.168.0.0/24(rw,insecure,no_subtree_check,nohide) /nfs4exports/home 192.168.0.0/24(rw,insecure,no_subtree_check,nohide) However, when I ls nfs4exports I get Data1 home which ties in, I think, with the logwatch report. Can someone please explain what I've misunderstood, and what I should do to put it right? Thanks Anne

Mock Shell Arch Command
by Ryan Wagoner 04 May '10

04 May '10

I've successfully rebuilt Red Hat EL PHP 5.2.10 RPMs using mock on a CentOS 5.4 i386. I wanted to be able to build both x86_64 and i386 versions so I reinstalled my builder system with CentOS 5.4 x86_64. Now I can build the PHP RPM successful for x86_64, but i386 fails with the following during configure /usr/bin/net-snmp-config: line 43: net-snmp-config-x86_64: command not found For the commands I am using mock -r centos-5-x86_64 php-5.2.10-1.el5s2.src.rpm mock -r centos-5-i386 php-5.2.10-1.el5s2.src.rpm I went into the shell on the i386 build environment mock -r centos-5-i386 shell The contents of /usr/bin/net-snmp-config has arch=`arch` echo $arch | grep -q i.86 ...... if [ "$arch" = "x86_64" ] ; then net-snmp-config-x86_64 $* exit 0 fi When I run arch from the mock shell I get x86_64. Shouldn't it see the correct architecture inside of mock? I thought that was the point of mock so I could build both i386 and x86_64 versions on the same system. Thanks, Ryan

Software Protection on centos
by premrajm＠digilink.in 03 May '10

03 May '10

Hi, I would like to have a software protection for my hardisk. I have some query regarding that (1) In Centos, is it possible to do a hardisk protection. Ex : Even if the hardisk is taken from a PC and used on another PC, it should not be executable. (2) Also if the entire binary of the source is mounted on a partition say /tmp, is it possible to make that mount point as protected, visible only after entering a password or similar to that.

TCP Tuning/Apache question (possibly OT)
by Kwan Lowe 03 May '10

03 May '10

Hello All: I've been requested to add some TCP tuning parameters to some CentOS 5.4 systems. These tunings are for the TCP receive buffer windows: net.core.rmem_max net.core.wmem_max Information on this tuning is broadly available: http://fasterdata.es.net/TCP-tuning/linux.html http://www.speedguide.net/read_articles.php?id=121 Potential downsides are available: http://www.29west.com/docs/THPM/udp-buffer-sizing.html >From the above, the rmem size is a function of the number of listening processes times the size of the receive buffer. Apache can initially create a bunch of server processes (StartServers directive, for example). In our environment we may spawn off 50 or more httpd listeners. Does each listener allocate its own buffer or is the parent process the only one? The tunable seems innocuous but I am concerned about the impact to memory given that there will be many listener processes. We are running fairly tight already and because these are virtual environments in a cluster, adding a meg or so per listener can equate to multiple gigs across all the machines in the virtual host cluster.

is it possible to resive /var online?
by Rudi Ahlers 03 May '10

03 May '10

Hi all, Is it possible, safely, to resize /var while a server is running? I urgently need to resize a full 2GB /var on a running server which is located at a remote location where no one can get to it for 2 days? The system runs on lvm. I already moved /var/logs to it's own LVM partition but it didn't help at all so I think it's better to rather just resize it. Google searches suggest taking the server offline, or boot into single mode. But this won't be possible for another 2 or so days and I urgently need to install more software on the server. tia :) -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
