CentOS 5.2 -- how do I choose a wireless network?
by Aleksey Tsalolikhin 06 Aug '08

06 Aug '08

Hi. We have a Windows laptop that has gotten too slow, it's borderline unusable, so I burned a CentOS 5.2 32-bit Live CD, just to try it out in the home. It boots up fine, but it does not connect to the Internet... Now we normally connect through a wireless network, there are several around here -- on the Windows box we choose the network to which to connect... but on CentOS there is no such menu? I went to Administration -> Network, and enabled the wireless interface, set to Auto and to DHCP, but it said, unable to assign IP address, and no connectivity... How do I connect to a wireless network, please? Thanks, Aleksey

DVI + VGA?
by MHR 06 Aug '08

06 Aug '08

I have an LCD monitor with both VGA and DVI connectors on it, and a video card to match (both connectors). If I want to switch from the VGA (currently in use) to the DVI, do I need to do anything special other than switch wires? I didn't see anything in google that was helpful (though I may not have used a smashing search...). Thanks. mhr

rsync question
by Mag Gam 05 Aug '08

05 Aug '08

Hi All, I am trying to understand the purpose of rsyncd. Why does it exist? Why not just use rsync ad-hoc or via script? Also, to a more serious note. I need to keep a filesystem on 1 server and another server synced by. What is the best way to do this? I want to have /source and /target to be exactly the same. I don't want any extra files in /target. I want the timestamps to be the exact same in /target. Does anyone have a good rsync arguments I can use? I have been using -avzl but I was wondering if there was anything better. TIA

64bit vs 32bit
by Matt 05 Aug '08

05 Aug '08

I am upgrading a server that mounts in a rack. Its going on the cheapest socket 775 CPU I can buy and in a 1u rack case. All its for is keeping some log files and doing some simple MYSQL/PHP database stuff. Not a work horse at all. Anyway, is it better to go 64bit or 32bit for the CentOS 5.x install? I do not see needing huge amounts of RAM or anything like that on this box. Would the 32bit version be more tried, proven and stable? Matt

Outbound connections not using primary eth0 IP
by Neil Aggarwal 05 Aug '08

05 Aug '08

Hello: I have a machine running CentOS 5.2 I added two IP addresses to eth0 by copying /etc/sysconfig/network-scripts/ifcfg-eth0 to /etc/sysconfig/network-scripts/ifcfg-eth0:0 /etc/sysconfig/network-scripts/ifcfg-eth0:1 and changing the relevant IP info. I am now seeing outbound connections failing at my firewall from services like NTP, etc. since they are now using a source address from one of the added IP addresses instead of the original eth0 IP which is allow through the firewall. I don't want to have to keep maintaining 3 copies of each firewall rule to accommodate the new IP addresses. Is there a way to tell the machine to use the eth0 IP address as the source address for connections? Here is the original ifcfg-eth0 file: # nVidia Corporation MCP55 Ethernet DEVICE=eth0 BOOTPROTO=none BROADCAST=206.123.70.63 HWADDR=00:30:48:7A:B4:FE IPADDR=206.123.70.50 NETMASK=255.255.255.240 NETWORK=206.123.70.48 ONBOOT=yes GATEWAY=206.123.70.49 TYPE=Ethernet Here is ifcfg-eth0:0 # nVidia Corporation MCP55 Ethernet DEVICE=eth0:0 BOOTPROTO=none BROADCAST=72.249.130.47 HWADDR=00:30:48:7A:B4:FE IPADDR=72.249.130.42 NETMASK=255.255.255.248 NETWORK=72.249.130.40 ONBOOT=yes GATEWAY=72.249.130.41 TYPE=Ethernet Here is ifcfg-eth0:1 # nVidia Corporation MCP55 Ethernet DEVICE=eth0:0 BOOTPROTO=none BROADCAST=72.249.130.47 HWADDR=00:30:48:7A:B4:FE IPADDR=72.249.130.43 NETMASK=255.255.255.248 NETWORK=72.249.130.40 ONBOOT=yes GATEWAY=72.249.130.41 TYPE=Ethernet Any ideas why this is happening?

Questions on cpu frequency scaling AMD vs. Intel
by Kai Schaetzl 05 Aug '08

05 Aug '08

I've been playing and comparing frequency scaling between AMD and Intel CPUs yesterday and there seem to be great differences between AMD and Intel and some gotchas. This is all on CentOS 5.2 with latest Xen kernels (which are supposed to be powersaving-enabled since 5.2). AMD: It seems once I get the AMD CPU to use the ondemand governor it works very well and very efficiently. But this is not set by default, one has to set ondemand explicitely in /etc/sysconfig/cpuspeed and run cpuspeed on bootup. Otherwise it just knows about userspace and performance and defaults to performance. Intel: On the other side ondemand is on for Intel CPUs automatically, but it doesn't seem to work. No matter if I run cpuspeed or not the current frequency is shown as 2000000. This is the scaling_min_freq for both CPUs I checked. The scaling_max_freq is 2.333/2.5. One is a Xeon Dual Core, one a Xeon Quad Core. With "not seem to work" for Intel I mean it doesn't act on demand as it should. I tested by gzipping and gunzipping a 4 GB image file. I used top to observe CPU utilization. With a dual core the idle percentage stays around 50% for a while and only goes below this threshold near the end of the operation. I deduce that means that gzip can make use of only one core and only when it comes to writing to disk or using other external tools it can utilize more CPU power because that task is taken over to the other core. Same observation with quad core (and 75%). There is no difference between AMD and Intel in this respect, but the task seems to run a bit more efficiently on an AMD CPU - e.g. it is able to max out idle at 0% at least for short periods while this is almost impossible to observe with the Intel CPUs. The timing also shows that the AMD is the fastest one. (The AMD, a very new low voltage X2, also runs at 2500 max.) My question: why don't the Intel CPUs don't scale up on demand? Could there be a bug in the driver that it measures overall utilization (which is at 50% most of the time) and not single core utilization, thus never reaching the threshold for scaling up? up_threshold is at 80 for both CPUs. (cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold) I have a somewhat related question. That very new AMD CPU mentioned above was not recognized by CentOS 5.2 and the current frequency was shown as 800000 (instead of 2500000), although it was running in full speed. The latest kernel corrected this. It's still unknown, but the frequency is now calculated correctly and thus frequency scaling works now (it didn't work when it was miscalculating at 800000). On the other hand, I have an older low-voltage AMD CPU (probably about 2 years on the market) that is recognized as X2 3800+ but frequency scaling fails because it miscalculates the current speed to 800 MHz as well. Is there anything I can do about that? Where could I check whether this CPU should be supported in full and frequency scaling working? (I'm not sure, but I think it may have actually worked when it was running in a different motherboard.)

File system goes read-only once in a while
by Mufit Eribol 05 Aug '08

05 Aug '08

Hi, My Centos 5.2 server (5.1 suffered the same problem as well) has a logical volume on a RAID 10 array (4 SATA harddisks on a Highpoint RR2310 controller). /etc/fstab has an entry for this array as below /dev/raid_vg0/raid_lv0 /mnt/raid ext3 defaults 0 0 Normally it works OK. But, file system of "this volume" once in a while goes "read only" mode. The RAID software reports no problem with the hard disks. After reboot, the system comes back in normal rw mode. What could be the reason?. I would appreciate any help/hint. Thank you, Mufit

GFS and Smaill Files
by Patricio A. Bruna 04 Aug '08

Hi, I had found on the list that i can improve the performance of GFS with small files if i adapt the size of the rsbtbl_size/lkbtbl_size values. But it also found that this has to be done after loading the dlm module, but before the lockspace is created. What means "before the lockspace is created", before the GFS partitions are mounted? How i do this? ------------------------------------ Patricio Bruna V.

Reloading /etc/hosts

I am doing some testing and am having to make many changes to /etc/hosts Is there a way to reload the /etc/hosts file without doing a service network restart? I hope that in a while I can run BIND with a bunch of faked-out zone files (did this once to crack a Vonage PAP2). But for right now, I cannot introduce BIND to the equation....

Using CentOS 5 as server; best way to setup NFSv4?
by Ryan Dunn 03 Aug '08

03 Aug '08

I've got a server running CentOS 5.2 and has a working NFSv4 server. I've been looking for some help on this on the net, but haven't come across anything that looks like it would pertain to my situation. Basically, I've got a mixed distro environment (CentOS, Fedora, openSuSE, Ubuntu, Puppy, and yikes possibly a Windows box) on various desktops and laptops that I want to connect to my server. Currently, I've got it setup so that it is only NFSv4 with a host mask. My first concern is that it authenticates to the machine, not the user. Second, that the user is identifed by the UID on the local machine, not the actual user name. Since Centos/Fedora start UID at 500 and Ubuntu/opensuse start at 1000, even though the names are the same, UID is not. I'd rather not have to reID on half my machines Third, I know I'll need samba for the windows box. So, if someone were to get on my local network and have the same uid as I have, then they could mount my shares as rw and have at it. The ideal situation is that a user would logon to a local box, then when he wants to access a share, it sends the credentials to the server, and mounts the share. This is all for my home setup; basically, I'd like to have my directories be mounted rw for myself, but if i have guests over, have them be able to mount read only (sharing pictures with family memebers that have laptops, etc). Thanks, Ryan

'initrd' image of CentOS (domU) on Ubuntu (dom0)
by Admin Admin 03 Aug '08

03 Aug '08

Hello, What is the best way to get the xen enabled CentOS 5.2 vmlinuz and initrd images for use as a guest domain (domU) on Ubuntu host domain (dom0). Is there a site where these are available? I am hoping that I could use the vmlinuz from the latest kernel rpm, if I go that route, how could I generate the initrd image given that my host is Ubuntu? These are for use with post install of domU, which is setup using xen-create-image. Thanks

Load Average ~0.40 when idle
by listmail 02 Aug '08

02 Aug '08

I am running CentOS 5 on a dual-dual-core Intel machine, and I am seeing a load average of between 0.35 and 0.50 while the machine is idle, i.e. no processes appear to be running. Both top and uptime report the same thing. Looking at top, I cannot see any processes that are using CPU time except for top and init, and they are not using enough cycles to push up the load average. According to top, there are occasional tiny (like 0.5%) bumps in the system usage occasionally, and almost no user space usage. Again, not enough to account for the load average I am seeing. I have tried a couple of kernel updates, and upgraded from CentOS 5.0 to 5.2, none of which make any difference. Has anyone else seen this? And can anyone recommend a way to figure out what is causing the load average to be this high when the machine is idle? Thanks, --Bill

OT: backup media options
by Monty Shinn 02 Aug '08

02 Aug '08

Greetings. Sorry for the OT, but I'm looking for some advice regarding archiving. I've always been a tape archive believer, but with SATA drives becoming more reliable and much larger, I'm wondering if it is time to change my opinion. What are the benefits/pitfalls to begin archiving to "enterprise" level SATA drives? Is it possible to use Amanda or Bacula to archive to a drive, and maintain a archive regimen? Archive to the drive, when the drive is full put it in an anti-static bag, and place it in storage. Possibly archive to a mirrored pair if one is really concerned. We are considering using LTO4 as an archive medium. With the tape densities these days, it appears the tapes are rather fragile, and that head gap seems awful small. Any thoughts are greatly appreciated. Again, I'm sorry for the OT, but I figured I'd get knowledgeable responses from this list instead of sales pitches... Thanks in advance for your time. Monty

My Firefox crashed and I lost sound, is there a way to release the lock Firefox had on sound when it crashed? I was streaming sirius radio at the time of the crash. Is there a daemon I can restart? I could just reboot but I'm not windows admin :) I logged out of the GUI then back in, would restarting X clear it up?

Having problems starting httpd & portmapper #service httpd start /usr/sbin/httpd: error while loading shared libraries: libm.so.6: cannot open shared object file: No such file or directory and I traced it to selinux, which I had just turned on for the first time: # sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Mode from config file: enforcing Policy version: 21 Policy from config file: targeted I can #setsebool -P httpd_disable_trans on and httpd starts - but there's zero enforcing now as I understand it. Further digging & I get to: # cat /var/log/audit/audit.log | audit2allow -m local module local 1.0; require { type portmap_t; type httpd_t; type file_t; class lnk_file read; class file { getattr read execute }; } #============= httpd_t ============== allow httpd_t file_t:file { read getattr execute }; allow httpd_t file_t:lnk_file read; #============= portmap_t ============== allow portmap_t file_t:file { read getattr execute }; allow portmap_t file_t:lnk_file read; Other stuff like postfix, postgrey, amavisd are working fine since turning selinux on. Before I make a mess of things with trying to make a new policy, shouldn't two basic services like portmap & httpd already be allowed to run out of the box by selinux? If not, am I going down the right path to get it working? Thanks -- Toby Bluhm Alltech Medical Systems America, Inc. 30825 Aurora Road Suite 100 Solon Ohio 44139 440-424-2240 ext203

Quation about CentOS 4 xenU kernel
by Kai Schaetzl 02 Aug '08

02 Aug '08

I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced rpm database doesn't include the xenU kernel anymore I installed the latest one again. I got this warning: WARNING: No module ata_piix found for kernel 2.6.9-67.0.22.ELxenU, continuing anyway Looking around I don't have this module for the old kernel (2.6.9-67) either. But it's referenced in modprobe.conf. Nevertheless, I could boot the VM. A locate shows this module in all non-xenU kernels under /lib/modules, sometimes in a scsi, sometimes in an ata subdirectory. I still have a backup of the old setup before the sync and this doesn't contain ata_piix in /lib/modules/2.6.9-67.ELxenU/kernel/drivers/scsi either. And no ata directory. So, I'm a bit puzzled now. Do I need that module to boot a Xen VM? If not, why is it modprobed? And why do I get this warning from the xenU kernel?

Remounting a USB flash drive
by MHR 01 Aug '08

01 Aug '08

I've noticed that once I right click on my flash drive icon and umount it, in order to remount it I have to unplug it and then plug it back in. Is there a command that will accomplish the same task without the unplug and plug back in physics? Thanks. mhr

PXE Booting floppy image
by Joseph L. Casale 01 Aug '08

01 Aug '08

Anyone know the correct syntax for specifying a floppy image in the /tftpboot/pxelinux.cfg/default file? I am trying to use: label Dos Bootdisk MENU LABEL Dos bootdisk FDIMAGE discimage.img But when I select it the menu, I get a message saying "Automatic boot in 30 seconds" and nothing happens. I would use: label Dos Bootdisk 2 MENU LABEL Dos bootdisk 2 kernel memdisk append initrd=discimage.img but this is a 2.88meg floppy and memdisk wont boot it? Thanks! jlc

BackupPC 3.1.0 on CentOS 5.2 triggers SE Linux denial

Hi. I've installed BackupPC 3.1.0 from Testing repository, to Cent OS 5.2 x86_64, and I am hitting an SE Linux denial - the httpd cannot talk to the BackupPC socket: type=AVC msg=audit(07/31/2008 17:18:53.623:410) : avc: denied { connectto } for pid=11767 comm=httpd path=/var/log/BackupPC/BackupPC.sock scontext=user_u:system_r:httpd_t:s0 tcontext=user_u:system_r:initrc_t:s0 tclass=unix_stream_socket type=AVC msg=audit(07/31/2008 17:18:53.623:410) : avc: denied { write } for pid=11767 comm=httpd name=BackupPC.sock dev=md0 ino=39813253 scontext=user_u:system_r:httpd_t:s0 tcontext=user_u:object_r:var_log_t:s0 tclass=sock_file Is there an easy way to fix this, like setting the BackupPC.sock file universally writeable?

gnome-session missing "--silent" switch
by Lorenzo Quatrini 01 Aug '08

01 Aug '08

Hi, following this documentation (http://tinyurl.com/66z6ly) I found that on the version currently shipped whith CentOS 5 (2.16.0) is missing the "--silent" switch for use with gnome-session-save Do you know a workaround to accomplish the same result of "gnome-session-save --kill --silent" wich save and close the current session without user intervention? Or can you point me on the right direction to rebuild the SRPM with the patch for this bug (http://bugzilla.gnome.org/show_bug.cgi?id=149447)? thanks, Lorenzo Quatrini

Login Feature
by Tom Browder 01 Aug '08

01 Aug '08

I asked one of my team mates to evaluate centos 5.2 as a more stable distro for our business use than Fedora which we have used for years. His main objection so far has been the lack of a neat feature of recent Fedoras (at least since 7) that allows a user to login as himself if the screen is locked by another user (a switch user feature). Is that feature available or is it planned? Thanks. -Tom Tom Browder Niceville, Florida USA

Restricting User Rights massively
by Dirk H. Schulz 01 Aug '08

Hi folks, is it possible to restrict the rights of a user to only do few, defined actions, e.g. only look up cpu and memory usage, but not walk around in the file system, not see any other hardware details, run any binaries/scripts? I know several different techniques to achieve parts of this (like chrooting him), but is there one technique to get it all? Dirk

how to install BackupPC on CentOS 5.2 -- use Testing repository
by Aleksey Tsalolikhin 01 Aug '08

01 Aug '08

Hi. I just installed CentOS for the first time, to make a BackupPC server. However, when I try to install BackupPC using yum, I get the error: No package backuppc available. I searched the Testing, Extras and CentOS Plus repositories, and found a BackupPC package only in Testing, at http://dev.centos.org/centos/5/testing/x86_64/RPMS/backuppc-3.1.0-1.el5.cen… which I downloaded directly. Just posting this in case somebody else has a similar issue. Best, Aleksey

Re: [CentOS] Will CentOS 6's upstream be based on Fedora 10?
by Ross S. W. Walker 01 Aug '08

I have always wanted a distro in-between long term support and cutting edge. Say one that uses the kernel/command line part of a long term distro and the gui and gui apps of a cutting edge distro (maybe 1 back from the cutting edge).

If you want something new, why do you think when CentOS 6 comes out it will be new ? And for how long ?

xfs on 5.2 (live cd + dvd)
by Michael Kress 01 Aug '08

01 Aug '08

Hello, I'm planning a server migration and being able to mount xfs file systems with the live cd would be a cruical feature. So before I download and try ... can anyone tell me whether the xfs is included in the 5.2 live cd? Later on I'm planning to install a new system with xen, 3ware 9550SX-4LP and xfs. The xen domains are of course located on xfs partitions. Do these features come with the standard dvd or do I have to build a custom kernel for that? Under centos-4.5 I chose xfs for performance reasons. With 5.2, is it still the fs of choice when it comes to performance or do you have better recommendations? (It will be a combined web and mail server with moderate traffic, i.e. not toooo much but not tooo little). Thanks in advance Regards Michael -- Michael Kress, kress(a)hal.saar.de http://www.michael-kress.de / http://kress.net P E N G U I N S A R E C O O L

I have restarted the operating system with CentOS's original kernel and done again my experiments. I found that bug has not occurred again. I don't know why. Maybe, the traditional libpcap has no provided enough capability like PF_RING. Or, perhapse something wrong is indeed in patched kernel or Dell hardware drivers. BTW, could you tell me what OS distribution you used in your testing PF_RING, RedHat AS4 or Others? And what kernel source codes are downloaded, from vendor's websites or www.kernel.org?

Static Linking, C++ Exceptions
by Darrin Thompson 31 Jul '08

31 Jul '08

I'm having a problem statically linking a big c++ application on Centos4. I can make it work on Centos5 and that's great. I just need to figure out a way to reproduce the problem on a small test case. The specific problem is that when I throw an exception, I get a segfault. It only happens on Centos4, and only on ia-32 machines. In an act of desparation I disassembled the bit of code that's segfaulting and got this: (gdb) disass Dump of assembler code for function _ZN14__gnu_internal10get_globalEv: 0x08579614 <...get_globalEv+0>: call 0x8577c3e <__i686.get_pc_thunk.cx> 0x08579619 <...get_globalEv+5>: add $0x3b31c7,%ecx 0x0857961f <...get_globalEv+11>: push %ebp 0x08579620 <...get_globalEv+12>: mov $0xfffffff8,%eax 0x08579626 <...get_globalEv+18>: mov %esp,%ebp 0x08579628 <...get_globalEv+20>: pop %ebp 0x08579629 <...get_globalEv+21>: add %gs:0x0,%eax <<<--- dies here! <<< 0x08579630 <...get_globalEv+28>: ret 0x08579631 <...get_globalEv+29>: nop End of assembler dump. When it dies, %gs is 0 which looks tls related. Only problem is that when I write tiny test programs to reproduce this, they work fine. %gs is nonzero and everybody is happy. But on my big hulking app, I can throw and catch an exception immediately on entry to main and it segfaults faithfully. Relevant compiler flags are these: g++ -c -o whatever.o -O0 -ggdb -Wno-deprecated -Werror -fPIC -Dmanything -Imanydirs whatever.cpp g++ -o whatever -static -static-libgcc many.o -Lmanydirs -lpthread -lanotherlib -lzlib -lesmtp -lnsl -lrpcsvc -lcrypt -lacl -ldl -lrt -landmanymore So I'm looking for some guidance on what things I could try to isolate this in a smaller app. -- Darrin
