perl one-liner issue
by Joseph L. Casale 17 Mar '11

17 Mar '11

I am trying to deduce the one liner for an rpm I am packaging to edit a php configuration file from within my spec. The line I am editing looks like: $conf['nagios_base'] = "/nagios/cgi-bin"; What are the escape requirements Perl needs from within the shell to search for this? As I have seen, the syntax is a mess, any pointers would be appreciated! thanks, jlc

CentOS 5.5 does not recognise SAS drives with LSI 1068E Controller
by Peter Peltonen 17 Mar '11

17 Mar '11

I need to do a new CentOS net install on a new server having the Supermicro X7DVL-3 motherboard: http://www.supermicro.com/products/motherboard/xeon1333/5000V/X7DVL-3.cfm Based on that info I assume the board having a "8x SAS Ports via LSI 1068E Controller". We received the server with 3 drives + 1 spare as hw RAID-5 preinstalled. During bootup I see that the drives are initialised and everything seems ok. The issue I am facing is that when trying to install CentOS no hard drives are recognised. I am a bit confused as others have reported CentOS 5.3 and 5.4 working "out of the box" with the same controller: http://www.linux-archive.org/centos/287219-installing-centos-5-4-64bit-serv… So I assumed that the megaraid_sas driver shipped with CentOS should support the controller? What confuses me also is the output of lspci: MegaRAID SAS 3208 ELP Does this mean its not the 1068E controller inside but something else? Or CentOS misidentifies it? So I assume the controller is not supported and I need a binary driver for it. For 1068e it should be: http://www.lsi.com/storage_home/products_home/standard_product_ics/sas_ics/… and the driver I need is inside the file mptlinux-4.26.00.00-1-rhel5.5.x86_64.dd.gz But how do I go applying this driver during installation as the server has no floppy drive? And what happens if I get the driver installed and then the server's kernel is updated? Do I need reinstall the driver somehow? Best regards, Peter

skype?
by m.roth＠5-cent.us 17 Mar '11

17 Mar '11

Well, at the urging of a friend who wants to talk face-to-face, I tried to install skype to my system at home (current CentOS 5.5). Got the fedora rpm; yum installed a library, then localinstalled skype, which is the current 2.1 beta. ldd shows an entry to linux-gate, which I don't have installed (or at least rpm tells me I don't). I try to run skype, and it complains about the version of glibc, even though I do have libstdc++.so.6. So, does anyone have any suggestions on a) how to get 2.1 beta working, or b) where I can find the *non* beta previous version...? Thanks in advance. mark "clues for the poor!"

I don't see this behaviour in the mandriva rpm files that i cut out and used. Next stop is getting SELinux to play nicely with it. It is also just another bit of software that i have to track manually though would be much happier to have it in the RPM database as my "check for updates" bookmarked tab group is getting longer and more painful to use. mike

problems creating read-only, 'consumer' dirsrv replica
by Jon Detert 16 Mar '11

16 Mar '11

Hello, I am trying to deploy an additional read-only replica (aka. 'consumer') in a single-master dirsrv environment. The master, and the other pre-existing consumer servers, are all 'fedora-ds' running on Fedora 7. I'm trying to add a consumer running on Centos 5.5. Ultimately, I intend to replace the Fedora ds servers with Centos dirsrv servers. I'm trying to deploy the Centos dirsrv consumer without running the dirsrv-admin. I've been following the directions at http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Adminis… , specifically in chapter 8. When I get to "8.7.2. Configuring Consumers from the Command Line" ( http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Adminis… ), I run into problems: 1) ldapmodify complains that I'm missing the required attribute 'nsds5replicaId'. So I add it, and guess at the replicaID number (cuz the guide says nothing about the ID). 2) even after resolving issue 1) above, I get an error: "ldap_add: No such object" The return value of the ldapmodify command is 32. The changetype of the operation is 'add', so ldapmodify knows it's trying to add an object. The input I pass to ldapmodify is just like shown in the guide, but w. the addition of the nsds5replicaId attribute mentioned in issue 1) above: dn: cn=replica,cn="dc=infinityhealthcare,dc=com",cn=mapping tree,cn=config changetype: add objectclass: top objectclass: nsds5replica objectclass: extensibleObject cn: replica nsds5replicaroot: dc=infinityhealthcare,dc=com nsds5replicatype: 2 nsDS5ReplicaId: 65535 nsds5ReplicaBindDN: uid=RManager,cn=config nsds5flags: 0 Any idea what's wrong? Do I have to first create dn: cn="dc=infinityhealthcare,dc=com",cn=mapping tree,cn=config ? If so, how? The guide doesn't seem to have a step for that, except for when adding a 'hub' dirsrv. However, I mean to add a 'consumer', not a 'hub'. Thanks, Jon

install specific version using yum

There is a great write up in the section "tips and tricks" on the mumble website for installing it on CentOS google knows about it it involves using the static build from sourceforge and extracting the conf and init files from the mandriva rpm then adding the necessary group and user works a treat and "free-er" than teamspeak 3 mike

Swap space for kvm virtual host
by Nataraj 15 Mar '11

15 Mar '11

I have a kvm virtual host running on what will become CentOS 6 with 12GB of memory and a Quad Xeon X5560 2.8Ghz . The store for virtual machines will be a software raid 6 array of 6 disks with an LVM layered on top. I'm not initially planning any major overcommitment of resources, though there could be a need for some overcommitment with a light workload on the guests. In recent years people seem to configure a wide range of different swap allocations. I was thinking initially to spread swap across seperate non-raid partitions on 4 of these disks, but the downside of that is if I put 2gb on each disk, then I can only swap processes that will fit in 2gb swap space. Also, if one of the disks fails, I have to reboot if anything was swapped to that drive. My questions are as follows: 1. What experience are others having with putting swap space on raid partitions? I was thinking about maybe swapping on a raid10 device, otherwise an LVM spanning multiple drives. 2. In practice, what kinds of swap allocation are people finding useful for a kvm virtual host of this size? I definitely don't want a system that is so overcommited that performance is impacted, but if some overcommitment is reasonable for VM's that have light workload, then I consider that. I can increase system resources when that becomes necessary. Nataraj

Web server becoming unresponsive : high load
by robert mena 15 Mar '11

15 Mar '11

Hi, I have a web server which is randomly becoming unresponsive. I've checked for hardware problems with no luck : - no ethernet errors - no disk errors - no memory errors So far I've managed to point the trouble at the web server since if I restart httpd (apache) it comes back to normal. This is not a shared server so I control (or at least like to think of) what is hosted so I have two suspects: a) my own code is behaving strangely. For example, a php script that in a given situation/parameters increases the usage. b) some sort of attack. Either in conjunction to a or other vulnerability. I am looking for advices in how can I pin point since looking at every line of code would be infeasible. Centos 5.5 / apache / php 5.2.10
