[SOLVED] VLC and WebCam networking

Been searching and trying all kind of command line combinations and GUI settings so that a web cam connected to my laptop can stream video to my main desktop through router. No success.
I cannot get VLC to stream, always errors. VLC works fine if I just start it and open /dev/video0. How do I get the signal down the network ?? Can someone put me on the right track?

Try this
cvlc v4l:///dev/video:width=352:height=288:fps=12 --sout '#transcode{vcodec=wmv2,vb=800,scale=1}:duplicate{dst=std{access=http{user=guest,pwd=123456,mime=video/x-ms-wmv},mux=asf,dst=:8080/stream.wmv}}' --no-sout-audio &
Must make the width, height (not sure about fps) fit your webcam mode.
It's unfortunate that VLC is the only tool for webcam streaming that works well.

[SOLVED] KVM and Bridged Networking

I've got KVM working and a Windows 2008 server installed on a image now, but it's only getting a NAT ip address. I need to get this server onto my main network, on Windows I'd use Virtual Box and Bridged Networking, but I thought I'd give KVM a try out.
I've followed the setup at https://wiki.archlinux.org/index.php/KV … Networking
Using Netcfg
Bridged networking is used when you want your VM to be on the same network as your host machine. This will allow it to get a static or DHCP IP address on your network, and then you can access it using that IP address from anywhere on your LAN. The preferred method for setting up bridged networking for KVM is to use the netcfg package. You will also need to install bridge-utils.
Netcfg#Configuring_a_bridge_for_use_with_virtual_machines_.28VMs.29
And this page https://wiki.archlinux.org/index.php/Ne … _.28VMs.29
I've got a bridge working I believe (all my stuff is DHCP by the way)

I've got "bridge" added to my rc.conf as a MODULE which is loaded. (I saw reference to this somewhere else on the forum that this might be needed)
I'm starting my VM with the following command
qemu-kvm -vnc 192.168.1.52:0 -hda Nekomi -m 2048 -smp 2 -net nic
Yet I still can't get an IP outside of the 10.0.0.0 range on the VM.
The VNC line above is because the HOST has not VGA output at all, completely headless.
I'm trying to get this working and trying to learn at the same time. KVM is new to me, as is bridged networking on linux.
Any ideas? Thanks

Sorry for the delay, bit a PC rebuild occurred :-(
Anyway, I managed to get this working with steps #1-#7 from the linked section. Thanks for that. I did have a few minor issues in getting a DHCP on the host machine itself, turns out I'd missed a single ) from the daemons section of rc.conf. A human error, but difficult to fix as the machine was rendered off the network and without a VGA card... fun!
I diverge, I have this script to bring up a bridge when the qemu-kvm starts
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
But when the kvm shutdowns it complains it can't find qemu-ifdown script. So I'm thinking of making one but just want to check it over first.
#!/bin/sh
echo "Executing /etc/qemu-ifdown"
echo "Removing $1 from br0..."
sudo /usr/sbin/brctl delif br0 $1
echo "Taking down $1 from bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc down
sleep 2
I've reversed the logic here, is the above the correct way to bring down the guest interface?

[Solved] Arch and virtual networking, not working as planned.

Running pfSense trough virtualbox, running virtual machines behind it.
What setup do I need, to get wireless LAN solely to pfSense. Currently I use the bridged setup in virtualbox as the WAN side. LAN is a host only adapter vboxnet0, all other VM's connect through that virtual adapter.
I would like to use a second host only adapter on a different subnet, but, once I create the adapter vboxnet1 and add it as second LAN card OPT1 to pfSense, internet stops working on the first LAN, though I can still ping google from the pfSense box.
How do I get Arch to not use the wireless connection but only the second host only adapter.
At the moment I use NetworkManager for the network.
Current setup (working):
Router – 192.168.1.1
Arch bare hardware, main OS – 192.168.1.9 (wireless)
pfSense WAN - 192.168.1.12 ( through wireless)
pfSense LAN - 10.10.2.1
host only adapter vboxnet0 - 10.10.2.3
I would like to add (not working):
pfSense OPT1 - 10.10.10.1
host only adapter vboxnet1 - 10.10.10.3
But this fails for unknown reasons.
What do I miss, or should I do different, thanks in advance, Mark
Last edited by qinohe (2015-01-30 12:39:32)

All is working well. I extended to four virtual adapters, one for the Arch host, and a wireless AP connected to eth0, bridged to pfSense. All applications on the host are finding the pfSense squid proxy, I have libproxy installed. Set the default gateway on the host to be the proxy of pfSense.
Now I can use my laptop to connect to insecure networks while not belonging to it, and host for friends at the same time, very nice

Xfce4 and gnome-network-manager [solved]

quoted from a previous thread
I solved it by uncommenting my <locale><charset> in /etc/locale.gen.
First you have to enable the locales you want being supported by your system. To enable or disable them, the file /etc/locale.gen is used. It contains every locale you can enable, and you have just to uncomment lines you want to do so.
As we want to setup an english UTF-8 conform system, we want to enable en_US.UTF-8. But for compatibility to programs that don't support UTF-8 yet, it's recommended to support any other locale, prefixed with en_US as well. Having this in mind, we enable this set of locales:
en_US.UTF8 UTF-8
en_US ISO-8859-1
After you've enabled the necessary locales, you have to run locale-gen as root to update them:
# sudo locale-gen
Generating locales...
en_US.UTF-8... done
en_US.ISO-8859-1... done
Generation complete.

(Solved) Having trouble installing vlc and openoffice

I am having trouble installing both VLC and Openoffice.
VLC
I tried typing in:
yaourt -S vlc
At first, it finds the package, and the first time I did it, downloaded quite a bit of stuff, and then it failed after installing a rather large package and then says :
error: failed retreiving file 'vlc-0.9.9a-6-i686.pkg.tar.bz' from archlinux.unix.heads.org : Not Found
Any idea what may be causing this?
OpenOffice
I tried typing in:
yaourt -S openoffice
Then it said it could not find openoffice in my /etc/customizepkg.d and then asks me to change my PKGBUILD and I had no idea what to edit in it.
Then, it tried to install it, and it tells me svn is not found in AUR.
What does this mean and how can I get openoffice?
Last edited by iscalio (2009-07-09 08:26:02)

You need to use the -y flag to update your local repository list.
Ie pacman -Sy
You can conveniently combine all of your tasks..
pacman -Sy vlc openoffice-base
Error retrieving a file means either
A) The mirror you are using is updating itself and you were unlucky enough to sync right when it was doing so.. youll need to wait a little while and try -Sy again then..
B) Related to A.. your database could be either older or newer than the mirror you are using. If you switched mirrors recently, this happens sometimes. Most mirrors update ~daily, but some update ~weekly. -Sy to sync.. you could try -Syy to force a full sync so that even lists of supposedly up-to-date repositories (core,extra,so forth) are synced (doing so is only good/useful if you have problems)..
C) Your mirror is offline.. change it to another one in /etc/pacman.d/mirrorlist
D) Your internet is not running / your DNS is not working properly.. try to ping a site you know is online to be sure. Google is always a good choice. ping www.google.com. You can ctrl+c to end it if it responds as expected. Fix your internet (see the wiki) and domain name server (/etc/resolv.conf and your router) if you have problems.
You may or may not also wish to pacman -Scc in order to clean out your cache of saved packages in case there is a download problem.
Your post gives the impression you don't understand pacman vs yaourt.. apologies if i'm wrong, but just in case:
Pacman is used for official binary repository files. Yaourt can do pacman's job in addition to its own with the same syntax (imo it does a pretty slow and lousy job of such though), but it's real original function is primarily to install 3rd party / community packages that the Arch devs either can't or won't maintain (and most often, have not "ok"ed them as safe to install). You should look at yaourt in the wiki.. when it asks you to change the pkgbuild I imagine you mean when it says 'what do you want to edit it with?'.. which you dont need to edit it at all. The reason it asks you is because yaourt can install stuff from AUR, which like I said is 3rd party / community stuff that can contain something malicious (AUR is open to submissions, unlike the official repositories) and you are highly advised to look it over for something fishy before compiling and installing. FYI -- believe me, you don't want to compile openoffice without reaaally good reason on a really fast machine. It hurts. Your machine will be as usable as a doorstop for a very long time while it's doing it's business. Just save your time and patience, install the compiled binary via pacman instead.
Please use the wiki, forum search functions, and man pages. Most of the Arch community is friendly and knowledgeable, but people get (rightly) irked when their work maintaining the aforementioned to answer queries like this one are ignored.

[SOLVED] Do I need to install Codecs if I use VLC and Clementine?

I realize that this might be a stupid question but I just want to be sure.
Do I need to install the Codecs listed on the Arch Wiki if I'm using VLC (for video) and Clementine (for audio)? If not, then is there any situation you can think of where I might need those codecs installed even after I have the necessary media apps?

After installing VLC and ALSA, some videos played correctly while others opened with incorrect resolutions and a screeching and tearing sounds.

[SOLVED]MSI P31 Neo -mobo and strange network problems

I can't get network to work properly with this MSI-mobo's integrated lan chip.
When I boot from Arch install cd r8169-module is loaded and I can get ip via dhcp. Strange thing is that I can access http but not ftp. When I change transfermode to passive from links ftp works. But during Arch install setup I can't access the repos.
When I boot to Arch after install network doesn't work at all. Only thing I get is resolv-errors when I try to use wget or pacman. R8169 module is loaded at boot and Ifconfig shows that I have ip assigned to eth0.
I also tried with 3com's 3c509 network card that I had laying around and I have exactly same network problems with it as I have with r8169.
I am really going out of my mind with this. I have a laptop with via's network chip and I've never had any network problems with it and Arch. I haven't changed anything in my routers setup and I just tried and the networking on my laptop works just fine.
I also tried Ubuntu Hardy on this desktop machine and networking works ok. Ubuntu also loads the r8169 module as Arch does.

UPDATE:
I tried booting with 2 RAM Chips and it works great! This seemed to be the problem.
The ram IS double sided which would explain it.
If you are wanting some more system specs, just ask and I will try and get the most I can.
Del UK:
If I could run 4gb it would be great but I cannot seem to find the SPD in bios. My BIOS is American Megatrends Inc. v02.61 so it would be great if you could help me with that!
If all else fails I might either just settle with 2GB or buy some new RAM chips. Can anyone please tell me some Ram chips which would be able to give this mobo 4GB?
Thanks

No Sound in VLC and Virtualbox

I have a workstation with two sound outputs - my ESI Juli@ and the HDMI out on my FirePro V5800. I have an issue where some applications cannot produce sound. That said, alsamixer and the OS itself do see the card, and it works just fine for sound from Firefox.
Originally, my issue was ALSA defaulting to the HDMI out and not giving me any audio. I first solved this by blacklisting the module for snd-hda-intel (the HDMI out). This "hack" allowed the OS to automatically choose the Juli@ as the default sound card and got sound working in the OS itself and Firefox. But then, I realized VLC and Virtualbox weren't working with the card and figured I should find a more proper solution. I got the following message from VLC:
"VLC failed to initialize your sound output device (if any).
Please update alsa-lib to version 1.0.23-2-g8d80d5f or higher to try to fix this issue."
Looking at the ALSA page on the Arch wiki, I decided that manually reordering the modules was necessary. The documentation there was poor, though, and I couldn't figure it out. Eventually, I found a forum post about the above error message and someone put things in more simple language. As such, I've modified my modprobe.conf to look like this:
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)
options snd-ice1724 index=0
options snd-hda-intel index=1
I must've done something right, because the OS and Firefox get sound just fine with the Juli@ as the default sound card without me blacklisting the HDMI out's module. However, my issue in VLC and Virtualbox remains with the same errror message, so I figure I'm missing something.
Here is the output of aplay -l:

I'm thinking the system seeing the Juli@ as two devices means I need to add another line to modprobe.conf, but I'm not really sure at this point. It'd be awesome if someone a little more expert regarding ALSA and maybe this audio chipset could please give a guy some help.

BUMP for this one.
I've updated packages since then, as well as manually selecting ALSA as playback for these two programs with no luck. I've tried using the instructions here:
http://www.alsa-project.org/main/index. … le-ice1724
But it seems like most of it isn't relevant... My Arch install has soundcore.ko.gz, snd-cmipci.ko.gz, and snd-ice1724.ko.gz just by proxy. The part about /etc/conf.modules is deprecated in Arch as well.
I'm dying to have sound in VLC and my VMs on my desktop. Please help!

Powerbook OSX 10.4 in sleep mode - open and loose network!

This is getting really annoying - I have a last of the line PB G4 Ti 1ghz with 1GB RAm running OSX 10.4 tiger. Use Belkin PreN router in the house and run G5 D2.3Ghz with Airport card as well. The problem only occurs when you close lid of PB to put to sleep. It also happens in public WiFi zones like hotels etc. Comes up with not connected to internet and when you look for networks it's all blank - doesn't remember a thing! I run Safari, mail and Skype on a regualr basis.
Any ideas? Cheers

I am looking for information on losing the airport when I put my g4 to sleep. Did you get any responses or were able to solve the question? I have to restart my computer each time to get the airport icon and my network. This started happening after i updated to 10.4.4
Thank you

When the network appliance is plugged into switch port 2 I am unable to ping the device from the laptop. When I plug it into port 3 I get the same result. In fact I am unable to ping the network appliance on any of the switch ports EXCEPT for ports 7, 8, 15, and 16. As soon as I plug the network appliance into any one of those four ports, the pings are replied to.
My question is - why am I unable to communicate with the network appliance on any ports other then ports 7, 8, 15, and 16? What makes these four ports different then the others?
Other Notes:
I have a second Linksys SRW2016 and notice the exact same behavior.
I’ve also tried a Linksys SLM2008 8-Port switch and experience NO communication problems on any ports.
I’ve tried a hub and it works 100%
I notice that after trying to ping the network appliance on a non-working port, I can see the device properly listed in the ARP table on both the switch AND laptop. So I am unable to ping the device yet it somehow makes it into the ARP table.
Any help with this issue would be greatly appreciated.
Best regards,
Rob

Hi,
Thanks for explanation that not all ports are the same.
I've just had a similar issue with a Siemens C470IP ip phone. It worked fine with my Dlink 8-port DES3010F switch which I've just replaced with the SRW2016, and also when plugged into my Draytek 2820n ADSL router's LAN ports. I'm a bit disappointed that I happened to plug the device into port 3 and suddenly my monitoring showed that things were not working properly. I checked cables and then remembered that auto-negotiation sometimes can cause problems.
On the SRW2016 if I leave the port with auto-negotiate on I see:
                              Flow
Port   Enable   Link Spd/Dpx Ctrl
g3      ENABLE   UP    10H     Off
Yet inspite this pinging the device does not work properly. That is I get from ping:
64 bytes from 192.168.0.36: icmp_seq=431 ttl=128 time=7.357 ms
Request timeout for icmp_seq 432
64 bytes from 192.168.0.36: icmp_seq=433 ttl=128 time=8.956 ms

Request timeout for icmp_seq 442

Request timeout for icmp_seq 444
Request timeout for icmp_seq 445
Doing the explicit configuration of 10Mb Half duplex as suggested does not help either. In fact it's worse as I get no responses from a ping and it does not make any difference if I enable flow control or not.
So must be the Siemens device? Well plugging into port 16 as suggested makes all the difference:
Auto negotiation works and the link comes up and works fine:
That is:
                Auto          Flow
Port   Enable Neg. Spd/Dpx Ctrl
g13      ENABLE   On   Auto    Off
g14      ENABLE   On   Auto    Off
g15      ENABLE   On   Auto    Off
g16      ENABLE   On   Auto    Off
and
                                Flow
Port   Enable   Link Spd/Dpx Ctrl
g14     ENABLE   DOWN -----   ---
g15     ENABLE   DOWN -----   ---
g16     ENABLE   UP    10H     Off
and ping shows what I expect:
64 bytes from 192.168.0.36: icmp_seq=353 ttl=128 time=5.918 ms

So why is this broken? Is it a firmware issue or a hardware issue? The firmware I'm using is I believe the latest though it looks rather old:
Boot Version:          1.0.1 (Date: 11-Jun-2006, Time: 18:43:59)
Software Version:      1.2.2b (Date: 28-Feb-2008, Time: 16:47:37)
Hardware Version:      00.03.00
If this affects me it's likely to affect others and I really wanted to buy the switch to add to the number of "managed ports" I have. This current behaviour is rather disappointing and I would have hoped that perhaps a firmware upgrade would solve this, or the documentation would be clearer that some devices do not work properly (auto-negotiation seems to be rather a troublesome subject). Is such a fix available?

AirPort Extreme 802.11n as a wireless router and local network switch?

Good afternoon,
I'm curious if its possible to have the APE in wireless network mode and connect systems via hard line as well?
I have an AirPort Extreme 802.11n set to "Create a Wireless Network" mode that is attached directly to a cable modem for internet connectevity. My issue is that while all wireless devices (several iPods, two iPhones and three laptop computers) connect to the APE without issue (and have internet access), when I try to plug in a Windows 7 desktop computer via one of the ethernet jacks, Windows is unable to connect and shows the network as "unidentified," spitting back a private IP address as opposed to a local LAN (this behavior repeats for an Ubuntu Linux box as well).
Not sure if the APE is misconfigured, this is a Windows 7 issue or if its improper use on my part (though this also precludes me from connecting a gigabit switch to the APE).
Thank you,
Nathan

Properly configured, the AirPort should provide both wired and wireless network client with Internet access.
At this point, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

[Solved] DVDs and CDs only work the first time I put them in

First lets get this straight before it is asked later on down the line. I am a 6 year Linux user and 2 year Arch user. I am currently using xfce4 and thunar as my file manager with thunar-volman installed. This has been a problem for the past year or so. I use my laptop most of the time (also Arch 64 and working like a dream) so I only try fixing it every so often to no avail.
I can put in a CD or a DVD and play them with VLC. Here's the catch: after I eject the CD/DVD and put in another one I can't play it or find it. The first time I put one in I even get an icon on the desktop. I don't think it's reasonable to have to reboot everytime I want to play another DVD (time wasted by constant rebooting is one of the very long list of reasons I don't use Microshaft products). I'm stumped, I can't be the only one, but my forum searches yield no treasures.

Thanks for trying, however, I posted what I use for a reason. I am using VLC, and I am a minimalist so I don't want a bunch of programs for doing the exact same thing. VLC is the only player for Linux that plays MTS files out of the box, so I'm not interested in switching or adding another.
Anyways, it's irrelevant because as I said before, thunar mounts it correctly the first time I put in a DVD or CD and displays an icon on the desktop for the disk. Therefore the problem is most likely hal related, since this began about the time we switched to hotplugging, and besides this I love hotplugging so I am also not interested in disabling that (who know what problems I'll introduce for my MAC keyboard and webcam if I do that). Yes I've read the hal and dbus wikis.
I can even get a USB CD writer to work with xfburn, however it's a relic and I think that's a sorry work around when I have internal drives that, in theory, work just fine. I wonder if it has anything to do with the drives being IDE when I used the SATA install option on the install disk (I did a fresh install last week) since my hard drives are SATA.
