Go to System/Preferences/Sound

On the hardware tab set up your sound card.  Probably "Analog Stereo 
Duplex" would be appropriate.

On the input tab select the appropriate device radio button for where 
your microphone is connected.  You might have to select the appropriate 
Connector if you are using a microphone plugged into your sound card. 
Adjust the Input volume setting.  Be sure that the [X] Mute check box is 
not checked.

You should see the bar meter responding to your voice.  If there is no 
response you've found your problem.  If the mic doesn't work then Skype 
isn't going to have any luck with it either.

Yes, as far as I know in Xen/KVM the tap devices are connected behind
the scenes to the bridge you specify in the config.

For running Skype with audio and video, install dependencies using this 
command:

yum install libXScrnSaver.i?86 libX11.i?86 libv4l.i?86 
alsa-plugins-pulseaudio.i?86 qt-x11.i?86

Hello Tait,

I'm learning about ethernet bridges and how it is applied to virtual
networking.  It seems that, in the past,  after you created the virtual
bridge (br0, br1 etc) you had to create the taps with tunctl and THEN
you assigned those taps to your VMs.  And now it appears that
virt-manager doesn't need these taps and you can simply point the VM to
the proper bridge.  My question is:  are the taps being used behind the
scenes (is it something libvirt does for us) or are the tap interfaces
obsolete now?

Thanks,
Jorge

Does running alsamixer and adjusting the levels for the appropriate 
sound card help?

I would think that it is a little easier to setup a bridge but not
assign an IP address for it on the CentOS host.

eg.

/etc/sysconfig/network-scripts/ifcfg-br0

DEVICE="br0"
TYPE="Bridge"
BOOTPROTO="none"
ONBOOT="yes"
NM_CONTROLLED="no"

/etc/sysconfig/network-scripts/ifcfg-ethX (where X is the interface
number of one of your intel ports and the HWADDR is the MAC address)

DEVICE="ethX"
ONBOOT="yes"
BRIDGE="br0"
HWADDR="xx:xx:xx:xx:xx:xx"
NM_CONTROLLED="no"


Restart the network service, then run brctl show - the new bridges
should show up.

Create the 8 bridges that you need and go from there, you should be able
to assign them in Virtual Machine Manager to the VMs.

Then in your VM guests you should be able to assign the IPs that you
want.

You can't really say it doesn't work for video - just that it doesn't
have to support any specific formats.  As long as your content matches
what your player handles, or your server  recognizes the player and
can transcode accordingly, it works fine.  It is 'just' streaming,
though.  I don't think it has a concept that matches dvd menus or
chapters that may work with players that do file mapping and can see
iso or video_ts rips on the server.

DLNA is a big mess.   works OK for audio, stinks for video.   The better 
set top boxes can play video files off SMB/CIFS and that works much 
better., assuming your video files are encoded in a format that the box 
supports (and most such boxes support a wide range of common video

[CentOS] Connecting ethX devices directly to a KVM/QEMU guest OS (no bridging)

[Chuck Munro]

Hello CentOS gurus, and a belated Happy New Year (or an early Happy 
Chinese New Year).

I'm in the process of building a CentOS-6 KVM host machine whose only 
function will be to run four independent 'm0n0wall' firewall guest 
instances. I have a couple of quad-port Intel NICs to provide four 
WAN-side and four LAN-side ports, which will not be shared with any 
other guests. Remote access to the host CentOS is via a separate 
on-board NIC, so the Intel ports are free to assign.

I've Googled until I'm blue in the face, but haven't found a clear 
explanation of how I can assign each ethX device directly to the guest 
OS rather than going thru the usual bridge configuration. I need to 
allow the m0n0wall OS to assign the LAN and WAN IP addresses, if that's 
possible without using a bridge.

Using the Virtual Machine Manager GUI to create the VM guests (which 
boot up and run nicely), the drop-down list shows all of the ethX 
devices greyed out. Do I need to somehow start the NICs without 
assigning IP addresses, so that they show up in 'ifconfig'?

Can anyone provide a clear, easy-to-understand procedure for doing this? 
If necessary, I don't mind using the command-line to create the VMs but 
the docs aren’t totally clear (to me, at least) regarding NIC assignment.

Thanking you in advance for your suggestions,
Chuck

options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ;

Failing is OK.  There are all kinds of reasons an update might fail
and you have to be able to handle that.  Even if you had your own
mirror it might be down or unreachable.   What you shouldn't have to
handle is installing some unexpected thing when you are just repeating
a command.  Besides, if something has been removed from the mirrors,
it is a pretty good hint that there is a better use of your time today
than pushing that package into production.

Yes, that's what I mean.  It is too bad the distribution doesn't have
a reasonable management system when it shouldn't be hard at all to get
the same versions of the same packages on two different machines - and
that is something almost everyone using an 'enterprise' distribution
needs.

Re: [CentOS] No sound over HDMI using nvidia graphics card

[Lars Hecking]

 Apologies for hijacking this thread, but I have posted here before and
 received not a single response. This is on CentOS5.

  http://lists.centos.org/pipermail/centos/2011-November/119707.html

 Other than the OP, I don't want HDMI sound, but the builtin sound device is
 not working. In a nutshell, a machine with this sound configuration

# lspci |grep -i aud
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio 
Controller
02:00.1 Audio device: nVidia Corporation GF108 High Definition Audio Controller 
(rev a1)
# 

 does not play any sound, whereas this otherwise identical one works

00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio 
Controller

 In the non-working case, /etc/modprobe.conf has

alias snd-card-1 snd-hda-intel
options snd-card-1 index=1
options snd-hda-intel index=1
remove snd-hda-intel { /usr/sbin/alsactl store 1 >/dev/null 2>&1 || : ; }; /sbin
/modprobe -r --ignore-remove snd-hda-intel

 and on the working machine,

options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-hda-intel

 The non-working config has /dev/audio1, which plays horribly distorted sound
 (cat file >/dev/audio1). The working config has /dev/audio, which works fine.

 The BIOS only has an option to enable sound, when I disable it, the snd*
 modules don't get loaded and volume prefs etc. don't work (kinda logical).

 I presume the problem is that there is no driver for the nvidia sound
 device, yet it is configured as card 0 (default). Again, in the non-working
 case I have

# cat /proc/asound/cards 
 1 [Intel  ]: HDA-Intel - HDA Intel
  HDA Intel at 0xf7ffc000 irq 169
# 

 and in the working case, I have

# cat /proc/asound/cards 
 0 [Intel  ]: HDA-Intel - HDA Intel
  HDA Intel at 0xf7ffc000 irq 82
# 

 Any ideas how I can get sound working on this machine?

 (It works very well under CentOS6, btw., PA let's me choose either device
  and the speaker tests are successful.)

Your local mirror doesn't have to be a full copy.  Granted, it is
easier to manage if it is, and drive space is cheap.

Yum's design goal was/is to be a dep-solver, not a management system.

I've always thought yum should have its own 'reproducible updates'
concept so you could  update a test machine, then tell all the others
to update to exactly that state even if some new things had been added
to the repositories - without having to make complete snapshots of
repositories containing stuff you don't even have installed just to
hold the state.  That is, that should have been a design goal for yum
since that is the way people should manage multiple machines - and yum
does sort-of know how to do that if you specify every package version
number.   But it really should just need a timestamp of the latest
thing in the repo at the time of the test/master update and  ignore
anything newer when you want it repeated.

That's true for DLNA in general whether it is on TVs or other media
players because most functions and codecs are optional. The server has
to know the device capabilities and often transcode things to match.

This might be sound-hardware dependent, and architecture-dependent as
well.

Here, on a Dell Latitude E6500, Skype 2.2.0.35 32bit installed (with
tons of 32bit stuff including sound libs, I can't remember where I
grabbed the install tips from exactly) on an up-to-date CentOS6 64bit.

In Skype settings:
Sound Devices ->
Microphone: PulseAudio server (local) <- anyway there's no other possible choice
Speakers: PulseAudio server (local) <- ..
Ringing: PulseAudio server (local) <- ..
[x] Allow Skype to automatically adjust my mixer levels

[CentOS] I/) Settings for Skype

I've managed to get Skype set up and working.  I can hear the other 
person talking, but she can't hear me.  During a conversation, I tried 
what I thought to be all possible settings in both the "Volume Control" 
application and in Skype itself.  But no joy.

To make matters more puzzling, I had skype working on this same machine 
last year using CentOS 5.6... or maybe it was 5.7... I don't recall. 
And I've successfully recorded my own voice with this same microphone on 
Audacity.

So is there some secret to getting the Skype settings right?

Or are there some (other) tests I can run outside of Skype to determine 
what the I/O settings within Skype should be.


Any help is much appreciated.

You can still access wiki articles: the pages load normally, only there
is a script at the end that redirect them to 'dark page'. Reloading the
page then stopping the load (stop, esc) before running the script let me
read the article I was looking for.

appears to be the case (mobile functions, normal web doesn't).

By the way, a trip to the regular Wikipedia site is useful in that it
provides an easy path for those in the US to contact their elected

Thanks. I'll try that later.
I'm presently installing mediatomb on another machine,
as I've been having other problems (almost certainly unrelated) 
on my server.

Incidentally, one difficulty I find with "Smart" TVs is that 
even with Samsung different models seems to have different software -
apart from the obvious 3D or not 3D -
and it seems very difficult to find eg whether one can browse
on a particular TV.

We have around fifteen machines (including my CentOS test machine) on a 100

Depends on your requirements. If you just want some port
filtering/forwarding it can be done by low power Atom machines or
even some old hardware (Pentium 2 possibly even older). ARM, MIPS
are also fine but check if your software/OS runs on that very special
architecture. If it is a mission critical firewall I'd recommend buying
new hardware instead of reusing your ten year old Pentium 3. If
you need new memory it's often cheaper to buy 8 GB of RAM instead of 1,
2 or 4GB nowadays.

Don't skimp on network adapters! 10$ adapters are usually not built
for 24/7 usage.

If you want to do deep packet inspection, (i.e. antispam, antivirus,
etc.) you should invest in decent (!) hardware.

If you'd like to access your firewall remotely you should consider a
remote management card like ILO, DRAC.

UPS, diesel motor, failover cluster, how much money do you have? ;-)

I would say that to some extent it depends on what is being updated. If
there is an update to the 'date' command then that could be applied
automatically. But updates, for example, to postfix/sendmail/exim etc on
a mail server, would not be applied by using 'exclude' in the yum.conf
file. These can then be checked and applied manually.

Re: [CentOS] Virtual Machine Manager error

[Darrin Wilkinson]

Hi,

I am getting the exact same error on a CentOS 6.2 X86_64 machine that I have
just setup.

Removed and re-installed ALL the *virt* and *qemu* packages ( re-installed from
the distro CD ).

The machine is a DELL Optiplex 755 with an Intel x86_64 processor.


I found there was a similar bug on Fedora a while ago and it was fixed here:

https://bugzilla.redhat.com/show_bug.cgi?id=726167


Not sure if the two are related but it seems likely given the descriptions...

Regards,
D

I think it would, at least for us.

Thanks. Will be looking into local repos it seems.

We've expanded our local calculation farm to now include mid-teen numbers, and 
manual updates is becoming a PITA...

based on personal experience, I'd say that number was at the '9' mark.
Once you go double digit, and you have those many machines in one
location, a local repo is the way to go. Perhaps then with one of them (
either a machine or a VM instance ) doing auto nightly updates, and
running a test to make sure all is still well and sending out a small
email to the admin with a OK or 'Trouble found in updates'

That would change things too much and make everything into a moving
target : not the best situation to be in. Also, its worth noting that
while its easy to slip into a mindset where one imagines all machines
everywhere being in vulnerable positions like on the internet etc, thats
never the case. Lots and lots of machines will run well disconnected
from the 'net', even these days.

Would it make sense to have a middle ground where the option to turn
on/off all system updates, by default, from the base repo's is put up
install time for the user to decide howto handle things ?

It would need to be limited to whats coming from the base distro repo's
though. Since we cant assume all repos on every machine are always in a
state where they are usable and upgradeable all the time. And yes, this
does mean that if the base repo's are moving automatically, third party
packagers and app vendors can no longer ask for and expect any sort of
state. Otoh, it might be argued that the whole point of a stable distro
is to not need that level of endorsement, the reality is that plenty of
vendors do.

pfsense will generally run just fine without any swapping with 160Mb of
memory. I'd recommend no more than 256Mb.
