[CentOS-virt] RHEL 5.5 Xen fixes

2010-03-31 Thread Pasi Kärkkäinen

Hello,

RHEL 5.5 has been released, and it contains many Xen related fixes.

Here's the most important of the them.. fixing a dom0 caching bug which 
could cause domU disk corruption when the domU disk was accessed from dom0 
after the domU was shutdown. Most people noticed this bug when pygrub
used wrong (cached) information.

pygrub uses cached and eventually outdated grub.conf, kernel and initrd:
https://bugzilla.redhat.com/show_bug.cgi?id=466681


And some more:

Xen hypervisor doesn't mask xsave feature from the guest; Fedora 11 PV domU 
kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=524719

[RHEL-5 Xen]: F-11 Xen 64-bit domU cannot be started with  2047MB of memory:
https://bugzilla.redhat.com/show_bug.cgi?id=502826

 Boot hang when installing HVM DomU:
https://bugzilla.redhat.com/show_bug.cgi?id=524052

[RHEL5 Xen]: PV guest crash on poweroff:
https://bugzilla.redhat.com/show_bug.cgi?id=540811

[RHEL5 Xen]: Cpu frequency scaling is broken on Intel:
https://bugzilla.redhat.com/show_bug.cgi?id=553324



RHEL 5.5 kernel changelog:
http://rhn.redhat.com/errata/RHSA-2010-0178.html


Work-in-progress (Not yet in 5.5):

Grub2 guest support for RHEL5 Xen pygrub:

Are these changes in the kernel or changes to the installed Xen? I'm
wondering if this effects anyone using Xen 3.4 or newer.

Some people, when confronted with a problem, think I know, I'll use
Windows.
Now they have two problems.

I think they're mixed.. you need to go through the bugzillas to figure out.
(and possibly compare to the kernel changelog above).

This may be a dumb/FA question but how do you run Xen 3.4+ with the latest
Centos kernel?

Are there centos/redhat kernels rebuilt with newer Xen or do you have
to do this yourself?

I see source for kernel 2.6.18 with Xen 3.4 here:

http://www.xen.org/products/xen_source.html

but that kernel does not have all the fixes that have gone into the
RH/Centos 2.6.18 kernel.

What's the difference between xen.org's 3.4.x series and Citrix

2010-03-31 Thread compdoc

My 2 cents:

When Red Hat picks a release of kernel, xen, kvm, etc., they
tweak, change, and test it until its 'enterprise' ready. If
they say you can run a business class server with it, I
believe them. Based solely on how well centos works.

Even though RHEL 5.4 doesn't have the newest of anything, it
does what it does well. Even if I have to put up with fewer
features or fixes than the current version, I'm leaving it
alone. 

I'm sure there are guys that can install newer releases of
everything needed to run the latest xen, and it might be
stable, it might not.

In my experience (several hundred RHEL xen boxes, and maybe 40
xen.org xen boxes over five years.)  until  recently, the xen.org 
xen kernel was quite a bit more stable than the RHEL xen kernel.   
(I mean, it didn't crash, but you'd have weird hangups with things
like xenconsoled dying, or a guest's network suddenly no longer
passing packets.)

The RHEL xen kernel has been getting markedly better over time, 
though, and the RHEL xen kernel has /much/ better driver support
than the xen.org 2.6.18 kernel.  My next server at prgmr.com
will likely have either the the CentOS xen kernel or the opensolaris
xvm xen kernel rather than the xen.org xen kernel for that reason 
(assuming I can get PVGRUB working and that paravirt ops linux guests 
work, which I believe they do.)

[CentOS-es] Operacion no soportada al borrar archivos ftp

2010-03-31 Thread Maykel Franco Hernández

Hola muy buenas, estoy intentando borrar un directorio de un ftp externo
que tenemos alojado en un hosting y todos los archivos hasta ahora me los
ha borrado bien hasta que me topado con el siguiente problema. Una carpeta
llamada ckfinder, quiero borrarla. Entonces lo que he hecho es montar el
sistema de ficheros via curlftpfs como si de un sistema de ficheros se
tratase ese ftp y le dado permisos de rw y para que puedan acceder todos
los usuarios así:

curlftpfs ftp://usuario:contase...@dominio /directorio/amontar -o rw -o
allow_other

Se monta bien y demas y los permisos los tiene igual que todas las
carpetas, pero hay unos archivos dentro que no me deja borrarlos, me dice
operacion no soportada:

r...@server1:/home/tecnico/Escritorio/comnet# rm -Rf ckfinder/
rm: no se puede borrar Â«ckfinder/userfiles/_thumbs/Images/carteles.gifÂ»:
OperaciÃ³n no permitida
rm: no se puede borrar Â«ckfinder/userfiles/images/carteles.gifÂ»:
OperaciÃ³n no permitida
r...@server1:/home/tecnico/Escritorio/comnet#


El problema son estos archivos que se encuentran en su interior:

r...@server1:/home/tecnico/Escritorio/comnet/ckfinder/userfiles# rm -R *
rm: no se puede borrar Â«images/carteles.gifÂ»: OperaciÃ³n no permitida
rm: no se puede borrar Â«_thumbs/Images/carteles.gifÂ»: OperaciÃ³n no
permitida

Y los permisos que tienen son estos:


r...@server1:/home/tecnico/Escritorio/comnet/ckfinder/userfiles# ls -lR
.:
total 8
drwxr-xr-x 2 root root 4096 2010-03-31 10:16 images

Alguien sabe por qué?? He googleado un poco pero no encuentro nada. Cabe
destacar que esos archivos los generó un programa que actúo en ese
directorio. Qué podría hacer para borrarlo(no tengo control de ssh bajo
ese server). Un saludo.

es muy común con servidores de alojamiento que no manejan correctamente

squirrelmail como webmail y demas y va como un tiro, me quedado asombrado

plugins como por ejemplo para cambiar la contraseña via web. Pero oí
hablar muy bien de roundcubemail, lo implemente metiendo un usuario en la

empresa creo que está mejor. Pero mi pregunta es, conocéis algún webmail,

a mi me gusta bastante, la suite de Horde IMP (webmail) Turba (contacs)
y demas apps. la suite basica viene en RPMs en CentOS-Extras creo

eGroupware [2]

Igual q Horde es mas q un webmail, es una app de colaboracion q
ironicamente he visto siendo usada y explotada muy bien por algunos de
mis clientes muy rapidamente ya q es facil de aprender y manejar, en

Sounds like you have your solution... Install sudo and configure it so
that particular users can use sudo to temporarily gain root
privileges.  You may even be able to copy your /etc/sudoers from
Ubuntu directly to CentOS.

Re: [CentOS] Keyboard problems on Centos 5.4

2010-03-31 Thread Kwan Lowe

 Simply plugging in my older Microsoft MultiMedia Keyboad 1.0A and some
 crappy old mouse, both of which are wired with PS/2 connectors, resulted
 in the problem going away. This kind of sucks because I like using my
 keyboard and mouse and I dont intend to leave these old things connected
 to my pc.

 I gather this means that the bug, that seems to have floated around for
 what 6 yrs, still hasn't been resolved?

Umm... It doesn't appear to be a CentOS issue ..
Have you tried re-synching the keyboard to the receiver?  Also, low
batteries can cause similar errors in wireless keyboards.

Re: [CentOS] mounting gfs partition hangs; Solution

2010-03-31 Thread sandra-llistes

It seems that all the problem was caused by selinux.
I booted all the nodes with the kernel option selinux=0 and now I can
mount GFS partitions without problems.
Thanks,

[CentOS] Define HTTP proxy system-wide (Squid and Squidguard) ?

2010-03-31 Thread Niki Kovacs

Hi,

I'm currently configuring Squid and Squidguard for filtering web access 
in a public computer room. So far, everything works fine.

I know how to configure Firefox to use a proxy, but there's no way to 
protect that configuration, e. g. a more knowledgeable user might 
circumvent this configuration. Is there some way to configure an HTTP 
proxy system-wide?

Cheers from the sunny South of France,

My email client wrapped the rightmost field of some of the output above,
but it's still discernible that epel wants to update to a newer version
of gmime, but (as you said) has no corresponding version of gmime-sharp.
 Conceivably, this could be the problem.  The versions I have of gmime
and gmime-sharp seem to be from a different repo:

# rpm -qi gmime gmime-sharp|grep URL
URL : http://spruce.sourceforge.net/gmime/
URL : http://spruce.sourceforge.net/gmime/

and so this might be a contributing issue.  So I deleted these two
packages (rpm -e ...) and then did yum install on them... which took
them from the extras repo, which seems to have gotten them from
sourceforge:

# rpm -qi gmime gmime-sharp|grep URL
URL : http://spruce.sourceforge.net/gmime/
URL : http://spruce.sourceforge.net/gmime/

(So this wouldn't seem to be a case of conflicting repos.)

Now, doing yum update again brought me back to the original problem.
:(  But at least we have more clarity to it: the extras repo doesn't
have a version update to gmime-sharp, a dependency for the update of
gmime.

So.. what's the next thing to do?  Just wait for an upgrade for
gmime-sharp?  Why does the extras repo not have it if it's a dependency?
 Perhaps it's still coming (?).  Or... has anyone else (somehow) been
able to upgrade to gmime v. 2.2.25-1.el5 ??  (How?)


Thanks, people.  I appreciate your efforts.

 Ahhh I've had a similar problem before.  Turns out I had multiple

 Perhaps you have both the i386 and x86_64 versions installed at the same
 time.  You may have to do something like
 
 rpm -e gmime-sharp-2.2.10-5.el5.centos.i386
 
 (or what ever package is conflicting)
 
 to get yum back to a sane state.

Kal, thanks for the tip on duplicates.  It's not the source of the

The BBC Microcomputer (2Mhz 6502) from the early 80s came with
32Kb RAM, 32Kb ROM (16Kb OS ROM, 16Kb paged ROM, for language etc).
RAM 0-0x7fff, Paged ROM (aka Sideways ROM - SWR) 0x8000-0xbfff,
OS ROM 0xc000-0x.

The language ROM idea was quite clever; it came with BASIC but you
could install 3 other ROMS (or with an expansion board, 15 other ROMS)
in there and so could have Pascal or a wordprocessor or an interactive
assember/debugger or...

So then some clever person thought what if I put RAM in there.
The first use was to be able to load ROM images into it, so effectively
letting you change the language ROMs you wanted to use.  But with some
bank switching it was possible to create a RAMdisk (the BBC was well
designed for this sort of expansion).  128Kbyte RAMdisks used 8 of the
SWR banks, typically on a expansion daughter board.  Since floppy disks
at the time ran from 100Kbyte (40track single sided single density)
to 720Kbyte (80track double sided double density), a 128Kbyte RAMdisk
was nothing to be sneezed at.

Next step was shadow memory.  The BBCs designed shared the program
memory with the screen memory.  The highest resolution was 20Kb in size
(which ran from top of RAM down).  Add in OS overheads (3.75Kb) and you
didn't have much space for programming!  So another form of paging was
used to help here; the OS write-character routines were intercepted and
banks were switched so the pixels were drawn and then the banks switched
back.  From a well-written programs perspective this was transparent.  A
little slow, but it worked :-)

That was a fun machine to use!

On the router level, you could block all the traffic and allow only the
threads initiated by proxy. Thus you make sure that no 'clever' user can
generate outbound traffic.

I don't understand your question or exactly what you are trying to do, but I 
suspect your problem has to do with the situation you described in other 
postings where you have random addresses bridged on the same network. 
Addressing is supposed to work like this: 
http://en.wikipedia.org/wiki/Subnetwork
and if the destination address isn't in the same subnet as the source it will 
be 
sent to the default gateway router unless you have configured a more specific 
route for it.

[CentOS] selinux on xen virtual machines

 I rebuilt my xen host with the 64-bit OS and am in the process of recreating

 virt-install, and so far none of the installation attempts has completed.

 Anaconda indicates installation should take about 2-3 minutes, but when it
 comes to installation of selinux policies, it just sits there, and I have
 no idea what it's doing. No progress 15 minutes later, and it doesn't make
 a difference whether I disable or not selinux in the kickstart configuration.
 What's the best thing to do in this situation?

 to disable some LUNS attached to a device... am I wrong? Can this be used to
 disable specific LUN?
 
I can be sure it has been a few years ago but you probly right in that
respect.

The only other idea I know of is to run the Real Time Kernel on those
Blades.  Then you need the kernel tools installed.  Pin down the
specific intterupt that the LUN resides on and blacklist it for that
specific scsi interface.  I dont that that either will get you a per lun
but they run on interrupts so they can be made to persistanly be
disabled.  cat /proc/interrupts will show it should but I must say i
have never disable a LUN through it only NIC devices and moving them
around to other CPUs.

You can use Nates idea also. It will work.  Put you a script in rc.d to
make it persistant.  I have a feeling you will need it in boot order
fashion though.

[CentOS] CUPS and virtual interfaces

2010-03-31 Thread m . roth

I've got a server with multiple virtual interfaces. Now, I only want CUPS
to advertise on *one* - eth0, not eth0:1 or eth0:gad

Looking at the CUPS manual, and cuppsd.conf man page, I see BrowseAllow,
but the entries are not clear enough for me to understand what they mean.
(Yeah, I know the docs are better than they were - read ESR's rant about
it from a few years ago.)

Specifically, I *think* I'd like to use BrowseAllow @IF, but I can't
figure out if that should be
BrowseAllow @IF(eth0)
or
BrowseAllow @IF(hostname)

Also, if it's interface name, and there are multiple virtual interfaces on
eth0, and I use the first of the two lines, above, will that *not* also
apply to the VIs on eth0?

 When I add selinux-policy and selinux-policy-targeted, the installer hangs

I found the solution, if anyone is interested.
First, this is not an ibm touch monitor, it was conwerted in a local shop. I
found that later, when i did some digging. It uses an MicroTouch matrix.
Microtouch is now used by 3m so you can get the drivers from 3m touch
systems. The trick is, that this kind of devices don't work with the new
driwers that are marked as Linux kernel 2.6. You have to use the old
drivers marked as Linuy Kernel 2.4. Dont worry, when you read the readme
file, you see that the drivers also work on 2.6 kernels. When downloaded you
get an source rpm. To sucessfully build the rpm on CentOS 5.4 you have to
unpack the rpm and modify the sources according to the attached document
(Touchware for Linux Kernel Module Issues.txt (google for the file name, i
don't know what the policy for attaching files is on this list)). After
modifying is just a matter of rpmbuld and installing rpm.

TouchWare for Linux Kernel Module Issues
Date Originated: 3 August 2006
Created by: Damir Suljic
Date Revised: 21 May 2007
Revised by: Damir Suljic

Overview
The TouchWare for Linux Software, part of the MicroTouch™ Software Suite, uses
a kernel module for the Linux kernel 2.4 and 2.6 operating system. This module
is responsible for communicating with the touch screen controllers in a touch
system.
This document details known issues with kernel module not jet resolved or
incorporated into released product. It gives basic steps to resolve the
problems on users’ site, and describes suggested changes required on source
RPMs.
The document first covers a build process of the kernel module and structure of
source RPM. It explains how to customize the Source RPM and deploy it on target
systems with new changes. The list of known issues will follow including
problem description and details about system affected.
Source RPM Build and Structure
TouchWare package is in form of Source RPM and main reason for this is Kernel
module included in this package. In one Linux system the kernel module needs to
be built and linked against current kernel version, and since Linux has vast
number of kernel versions available we decided to allow users to build our
package against their version. Now with every new version it is possible to hit
a situation where kernel module will not build or will not load on target
system.
After initial installation of source RPM into build directory (usually
“/usr/src/rpm directory”) the building binary RPM (all this is described in
Readme file included in package) will have either failure while building or
while installing binary RPM. In both cases you will have to investigate in more
details what and where in process the errors were happening. In case of build
error the command line output will give more information what file did fail to
build. If binary RPM build successfully but after installing it kernel module
did not load, you can check this by issuing “lsmod” in command line and look
for TWDrv, check “/var/log/messages” file for errors related to TWDrv (“invalid
module format”, “unresolved sysmbols”, etc).
Customization of Source RPM
To make changes on source RPM you will have to extract TWDrvSoureces.tgz file
(usually found in “/usr/src/rpm directory/SOURCES” directory) in temporary
directory “/usr/tmp/mytemp”. After extracting sources change directory to
“/usr/src/mytemp” and you will see directories and files from our package. One
of the directories is TwDrvKit where the kernel module files are located. Make
needed changes on TWDriver.c file. Test build it by issuing make command, and
insert module with “insmod TWDrv.ko”.
If the changes were acceptable, change directory to “/usr/tmp/mytemp” and issue
“tar –czf TWDrvSources.tgz *” (it is * for all files in current

Well, did that... and no joy, from another box, I can still telnet to the

Yes, it's needed by tomboy, an applet I use.

It appears that EPEL uses Fedora Project.

Interesting.  I tested a Base CentOS package and it has
builder10.centos.org.  Perhaps the extras are build using a
different method.  The gmime package from epel has
x86-07.phx2.fedoraproject.org.

 and there is no Packager
 field.  I tried using the --queryformat option a few different way to
 output the packager, but no luck.  That would be a big help in figuring

It must be an optional field:
$ rpm -qi cacti | grep Packager
Packager: Dag Wieers d...@wieers.com


 

 That is interesting.  Did your yum install command specify to install
 gmime-sharp?

 Yes, it's needed by tomboy, an applet I use.

OK.  That makes sense.  Yum will make the transaction consistent by
using the older versions to meet the dependency since no version was
installed.

 

 So.. what's the next thing to do?

 Either exclude gmime from the epel repo

 Would that be simply exclude=gmime* in epel.repo ?

IIRC that will work.

[CentOS] Release 6?

Since 5.5 is now out from Red Hat and most likely our amazing CentOS
team has already jumped on that, is there any word on Release 6?  IIRC
it's already a year out of date (base was supposed to be Fedora 10),
so I have to wonder.

I didn't see anything jump out at me on the Red Hat site, so - anyone?
