Re: [CentOS] IPSec VPN Setup?

2010-03-10 Thread Jobst Schmalenbach




Hi

I can second that, Openswan is the way to go (sorry the ONLY way to go).
Centos has the latest, but I would highly recommend to have Centos on
both ends.
Centos is one of the distros that uses NSS by default and standard out
of the box, so this makes is easier.

There's also a PDF booklet (get that from amazon, its written by Paul
Wouters, one of the Openswan developers), link on the website.

The toughest part is getting the keys and connections right, personally
I would not do it without subscribing to "us...@openswan.org" first,
they are helpfull and you will find Paul on the list, too.

Been using Openswan (well it used to be freeS/WAN, hence the animal
used) for many years and once you set it up and have the key exchange
working you never have to change a thing again other then (in my case)
"yum update openswan".

If you have trouble connecting to the remote side, ike-scan can help in
getting your key exchange settings right.  That is usually the hard part, in
my experience.

Subject: [CentOS] IPSec VPN Setup?

Hello Everyone,

I have been tasked at work with setting up a VPN connection from our
server to a client's network. The only problem is that I have never
done anything like this before, so I am not sure where to start.

We are running CentOS 5.4 on our server. I do not yet know what the
client is running for their VPN, the only thing I know of from the
client, is we need to use IPSec for our VPN connection to them. I have
been googling, and have found quite a bit of information, but it is a
little overwhelming, as I am new to setting up a VPN. Is the a
"standard" method for doing this sort of setup that I am missing so
far?

If anyone has any quick pointers to get me started, that would be
greatly appreciated.

Thanks, I googled it and found it (Jan 14 by Kevin Kempter). I'll give

[CentOS] FreeNX : forward audio from server to client ?

2010-03-10 Thread Niki Kovacs
Hi,

I setup a FreeNX server with a GNOME desktop, and I can access it from a 
client with the NoMachine client. Everything is running fine, and now I 
only have two problems left : audio and printing forwarding. I'll follow 
the "only-slay-one-dragon-at-a-time" rule and take care of audio first.

Did anyone manage to forward sound with FreeNX ? Here, server and client 
are using CentOS. And yes, I did check the little "enable multimedia" 
checkbox on the client, but to no avail. Whenever I play a sound in the 
client session, it comes out on the server speakers.

Any suggestions ?

2010-03-10 Thread Scot P. Floess

I've had bad luck myself with sound - but using NoMachine...  And, for me 
it only seems to work where sound is played for a Windows client machine 
to a NoMachine CentOS server.  The only sound I can get is using XMMS... 
If I start a web browser (like Firefox), I do not hear anything if I go to 
Youtube or the like...

I'd love to know how to get sound working as well :)

I just managed to get it working. In GNOME, you have to select ESD 
instead of ALSA, then it works. And on the client sound, select the 
Enable Multimedia checkbox.

So, I was trying all this in KDE...  From KMix, it shows that there are no 
sound cards at all...  I think I tried system-config-soundcard - but that 
didn't work.  Also, if I remember correctly I get an error in KDE about no 
sound card present...

Interesting. I've installed wicd but it seems to be saving the password 
wrong. I can connect and it does save something in the password field. 
However when I restart (or even simply logout and login again) it fails 
to connect until I manually update the password.

I think you are going to have a difficult time and I think you will have
to compile ruby from source because CentOS 4 has a very ancient version.
It can be done though.

ignoring that CentOS 4.8 is also a current release then I suppose what

Go to

   http://rubyonrails.org

and download the source for the recommend version of ruby to use with rails.

It's trivial to build - it builds on both CentOS 3 and CentOS 4.

I don't know anything about rails but to install it you simply type

   gem install rails

It's a gnome-keyring bug, only even recently fixed in fedora,

In particular,
https://bugzilla.redhat.com/show_bug.cgi?id=453880#c38

 Unless you already understood:

Thanks for the reply. I was originally going to look into using

It would be impossible to have ruby 2.3.5.8 on any computer since the
'current' (stable) version is 1.8.7 and the 'development' (unstable) is
1.9.1

CentOS 4 has something like version 1.8.1-7 which really isn't rails
suitable (you need AT LEAST 1.8.4 and you can passably use 1.8.5 like on
CentOS 5).

I think your questions are in the realm of CentOS thus far but questions
that are specific to RoR applications are probably not and probably
better handled on RoR list.

You must update Ruby first.  You can obtain ruby-1.8.5 for CentOS-4
from the centos-testing repo.  Once you have that then you can
install the latest Gem manager from rubygems.org.  Once Gem is
up-to-date installing Rails should be simple.

However, be advised that some gems do require at least Ruby 1.8.6. 
Rails does not but be aware that other things that you may wish to
use with Rails might choke on 1.8.5

I may have made a typo.  I have

Rails: 2.3.5.8
Ruby: 1.8.5
Gems: 1.3.4
SQLite: 3.3.6
MySQL: 4.1.22

So, theoretically, I should be OK.

[CentOS] An odd IPMI problem

2010-03-10 Thread m . roth
Well, we're figure the board's got problems, but I installed OpenIPMI a
couple weeks ago, and fired it up as a service, then added a cron job.
That all ran well until last evening; we came in to find 5 zillion emails
complaining
Unable to open SDR for reading

I worked my way through logs, and googling, and then trying to run
ipmitool by hand, and it complains there's no such device as
/dev/ipmi[three versions].

More googling, and down to modprobe, then insmod, of ipmi_si. Then trying
to give it parameters, and it continually comes back (after 5 min of
trying) with "No such device".

One thing I note: after I found the docs for IPMI, I found the list of
parms , and gave
it, among other things, the slave_attrs. Then I look at dmesg and
/var/log/messages... and it seems to be utterly ignoring that parm. That
is, I say (and get)
$ insmod
/lib/modules/2.6.18-164.11.1.el5/kernel/drivers/char/ipmi/ipmi_si.ko
ports=0xca2 slave_addrs=0x10
insmod: error inserting
'/lib/modules/2.6.18-164.11.1.el5/kernel/drivers/char/ipmi/ipmi_si.ko': -1
No such device

and in the log
Mar 10 11:24:36 south kernel: IPMI System Interface driver.
Mar 10 11:24:36 south kernel: ipmi_si: Trying hardcoded-specified kcs
state machine at i/o address 0xca2, slave address 0x0, irq 0

location
Mar 10 11:30:12 south kernel: ipmi_si: Unable to find any System Interface(s)

Notice that it's looking at slave_addrs of 0x0 and 0x20, *not* 0x10.

Any clues?

Re: [CentOS] Dependency problems with Yum update

Peter -

I forgot to mention that I did install with yum a test version of Ruby 
on Rails.  Would that have installed files that are out of sync with 
other CentOS 4 files?

[CentOS] Kernel Panic with wl.ko (Broadcom wireless driver) [CentOS 5.4]

2010-03-10 Thread Martin Jungowski
Been experimenting with CentOS 5.4 some more. In order to get my wireless 
card to work (Broadcom BCM4311) I need Broadcom's wl.ko driver (http://
www.broadcom.com/support/802.11/linux_sta.php). It compiles fine after 
the necessary modification in typedef.h, loads and wireless works. 
However, as soon as I put some load on that interface (scp something from 
another machine, download something with Firefox, etc.) the machine 
kernel panics. I've tried the stock 2.6.18 kernel, the latest 
2.6.18-164-11, and the latest patched 2.6.18-164-11-bug4139.4192.4196 
(necessary to get my ALPS touchpad to work). I've tried two different 
versions of Broadcom's driver: 5.10.79.10 and 5.60.48.36. It doesn't 
kernel panic when I unload the wl kernel module, plug in a network cable 
and copy those files over ethernet.

I downloaded the 2.6.27 kernel source and compiled my own kernel and it 
seems to work with that. However, for some weird reason, with any given 
self-compiled kernel (tried 2.6.18-8, 2.6.25 and 2.6.27) klaptop won't 
allow me to configure any standby/hibernation options because it doesn't 
recognize any of them. They do work perfectly fine though, I can pm-
suspend the laptop from command-line.

Any idea what else I could do? Either getting wl.ko to work with 2.6.18 
(does somebody have a version older than 5.10.79.10 that they could email 
me?) or getting klaptop to realize that the laptop does indeed know how 
th suspend and hibernate with a non-CentOS-kernel would be fine.

Thanks,
Martin

No, I don't have. What I want to have is: None-root users shall be
allowed to run some commands as root whithout password. And, on logging
on, the users shall see, what commands they are able to run.

Re: [CentOS] FreeNX : forward audio from server to client ?

2010-03-10 Thread Scot P. Floess


So, this machine does have a sound card (not sure that matters).  I used a 
different machine (no sound card) and was able to use XMMS and KDE - but 
not anything emitted from a Web browser.


Again, the CentOS machine does have a sound card - so sound works 
locally - but not over NoMachine.

[CentOS] unable to get domain status from libvirt & KVM

2010-03-10 Thread Tom Georgoulias
I have a python script that monitors the VMs on physical host servers 
running Xen, but the script doesn't work properly on a server I just 
built with KVM.  The script runs as a non-root user and simply gathers 
some details on the status and names of the domains running on the host.

Both Xen and KVM servers are running the same version of libvirt 
(libvirt-0.6.3-20.1.el5_4) and have the same, default 
/etc/libvirt/libvirtd.conf config file.

To troubleshoot, I've been running python interactively.  Here's how my 
Xen servers behave:

$ python
Python 2.4.3 (#1, Sep  3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import libvirt
 >>> conn = libvirt.openReadOnly(None)
 >>> domains = conn.listDomainsID()
 >>> print domains
[0, 3, 15, 16, 21, 24, 26, 30, 32, 36, 38, 41, 43, 45, 47, 49, 51, 55, 
63, 67]
 >>>

When I try the same thing on the KVM server:

$ python
Python 2.4.3 (#1, Sep  3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import libvirt

14:33:07.368: error : No vport operation path found for host2
 >>> domains = conn.listDomainsID()
 >>> print domains
[]
 >>>

(The vport stuff is weird, but I found this posting that suggests its 
harmless 
(http://www.mail-archive.com/libvir-l...@redhat.com/msg17477.html) so 
I'm ignoring it.)

However, when logged in as root on the KVM server, it works just like my 
Xen servers:

# python
Python 2.4.3 (#1, Sep  3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import libvirt
 >>> conn = libvirt.openReadOnly(None)
 >>> domains = conn.listDomainsID()
 >>> print domains
[1]

Again, on the KVM server, plain old "virsh list" with the debug level 
set to "2"

$ export LIBVIRT_DEBUG=2
$ virsh list

[CentOS] About addition of hardware and kernel

We have acquired 1 CPU and 2 GB of RAM additional to improve the functioning of

Should work flawlessl after installing the additional CPU and memory; maybe 
you want to check the server vendor's support pages for BIOS upgrades, 
there may be newer versions. As you have to take the machine out of service 
anyways, this is a good time to check this, too.

(OTOH: Never touch an running system, so if it finds all the memory and CPU 
installed additionally and there's nothing noted in the BIOS changelog, you 
can ignore it.)

HTH,

If you are running a SMP kernel then it should be able to run either 2 or
4 CPUs without any reconfiguration.
Run the command uname -a to see what type and version you are currently
running.

Re: [CentOS] FreeNX : forward audio from server to client ?

2010-03-10 Thread Scot P. Floess


I should say that the KDE machine - was running Fedora 12 with no sound 
card whatsoever.  Again, XMMS worked from the Fedora box back to a Windoze 
NoMachine client.  It didn't work to a Linux client (Fedora nor CentOS) 
that did have a sound card.


In both cases, the client machine didn't work when a web browser was 
involved - for example watching Youtube videos.

There is a "CentOS" kernel 2.6.24. If you wish to give it a try, you
can download from my site at:

http://centos.toracat.org/kernel/centos5/realtime/

It is a direct rebuild of the Red Hat MRG realtime kernel[1]. Please
note that I offer them for testing purposes, not for production use.

And with the increase of RAM to 4GB? would not have problems with this kernel?

sounds like it wants to replace libmysqlclient14 package which a lot of
packages seem to require.

Just out of curiosity, why would you need compatibility with ancient
openldap libraries anyway?

what mysql do you have installed on this machine ?

also, running yum with -d8 will tell you exactly what is going on, and 
why the packages cant be found. try that, if its still confusing - put 
that on a pastebin and post the url to that here ( make sure you put the

These are the two commands I ran:

  966  gvim /etc/yum.repos.d/CentOS-Testing.repo
  967  yum --enablerepo=testing install ruby ruby-devel ruby-rdoc

Could that have created the problems I am having now with a yum update?

You don't need a soundcard on the server if setup with a dummy ALSA  
device.

You do need ESD or pulseaudio setup properly on the server/client as  
well I believe for NX to work.

Why Flash doesn't come over by default is because it uses OSS instead  
of ALSA, so in order to get that working you need the ALSA OSS  
emulator installed on the server.

Don't ask me how to do it, I am trying to forget even having tried it  
and when it was working quality was terrible and control was touchy.

Your definitely better using Fedora for the server here as sound  
support in CentOS stinks, but then again I don't use it for sound and  
video support.

Google Flash and ALSA and prepare to go down a rat hole on this.

Well, I am learning / testing kvm myself, so what I write might not be
precise. But because no one seems to be responding ... :)

Look into /etc/libvirt/libvirtd.conf and check out the section "UNIX
socket access controls" and make appropriate adjustment.  [ I created
group 'libvirt' , added myself to the group, and uncommented the line
"unix_sock_group = "libvirt"".]  Then adjust also the permission bits
of the directories and files in /var/run/libvirt to allow access to
the group libvirt.

With some luck, you should be able to run the virsh command (for example):

virsh -c qemu:///system list --all

I'm sure there are more authentic way of achieving this. :)

Also, if you create a guest with the -c qemu:///session option, that
would allow non-root user to connect it.  For more details, please see
http://libvirt.org/uri.html .

Another hint: you will have a better chance of getting replies by
posting to the centos-virt mailing list.

Intel does not have a NUMA architecture solution for quad socket boards 
yet and so bus contention kills scaling on quad socket Intel solutions. 
Right now, AMD owns the quad socket market when it comes to performance.

Anandtech did some testing last quarter where they compared what appears 
to be the best quad socket Intel solution against the best dual socket 
Intel solution and the dual socket solution ran circles around the quad 
in some tests and pretty much matches it in other tests.

http://it.anandtech.com/IT/showdoc.aspx?i=3653&p=1

According to the article, Intel will be coming out with something that 
will scale at the quad socket level some time this year so things are 
probably going to change on this front.

[CentOS] RAID 5 on Install?

2010-03-10 Thread Slack-Moehrle

Hi All,

I cannot seem to find a resource that will allow me to RAID5 3 x 1tb drives on 
system install. Can this be done?

Re: [CentOS] RAID 5 on Install?

2010-03-10 Thread Gé Weijers

This can be done. You cannot boot from a software RAID5 device, however.

I'd do something like this:

on each drive, create a 'small' (256MB or so) primary partition 
(/dev/sda1, /dev/sdb1, and /dev/sdc1), and set the type to

"Software RAID".

Also create a second partition on each drive that takes up the rest of
the space, and also set it to "Software RAID".

Now create two RAID devices:

Combine /dev/sda1, /dev/sdb1 and /dev/sbc1 into a >>RAID1<< device, and 
format it as a ext3 partition mounted as /boot. (Grub can boot from a 
RAID1 device, but not from any other software RAID)


Combine /dev/sda2, /dev/sdb2, and /dev/sdc2 into a >>RAID5<< device, and 
set it up as an LVM PV.


Now create an LVM logical volume, and add your swap, root and any other 
file systems you want to it.


That should do it.

Re: [CentOS] Dependency problems with Yum update

What is the syntax for that?  This is what I initially ran:

  966  gvim /etc/yum.repos.d/CentOS-Testing.repo
  967  yum --enablerepo=testing install ruby ruby-devel ruby-rdoc

sounds like it wants to replace libmysqlclient14 package which a lot of
packages seem to require.

Just out of curiosity, why would you need compatibility with ancient
openldap libraries anyway?

thats largely because the current generation quad socket processors are 
still using last generation CPU cores, the current dual socket are the 
new I7/nehalem cores, which are inherently a lot faster.

ignore that - you don't need to run createrepo

what did you change when you edited CentOS-Testing.repo ?

btw... I tend to install more ruby bits (example from EL5)
ruby-ri-1.8.5-5.el5_3.7
ruby-rdoc-1.8.5-5.el5_3.7
ruby-devel-1.8.5-5.el5_3.7
ruby-libs-1.8.5-5.el5_3.7
ruby-mode-1.8.5-5.el5_3.7
ruby-1.8.5-5.el5_3.7
ruby-irb-1.8.5-5.el5_3.7

but I suspect that ruby-libs is automatically pulled in with your above
yum command.

Re: [CentOS] Dependency problems with Yum update

Craig -

I ran 966 and 967 below.  Then

   968  wget http://rubyforge.org/frs/download.php/57643/rubygems-1.3.4.tgz
   969  tar xvzf rubygems
   970  find / -name rubygems*
   971  tar xvzf /root/rubygems-1.3.4.tgz
   972  ruby rubygems-1.3.4/setup.rb
   973  gem install rails

Next I used gem to install sqlite3 on the suggestion that I needed to 
have the gem version only to find out that I needed sqlite3-ruby, so I 
uninstalled sqlite3 and tried to install via gem sqlite3-ruby, but it 
cannot be installed without ruby 1.8.6.

Seems to me that the IPMI driver can't find the IPMI hardware. What kind of 
server are you trying this on? Is it known to work with the IPMI-driver in 
vanilla CentOS-5.4?
