From news at siddall.name Sat Nov 5 16:23:01 2011 From: news at siddall.name (Jeff Siddall) Date: Sat, 05 Nov 2011 12:23:01 -0400 Subject: [K12OSN] Run a localapp with realtime scheduling? Message-ID: <4EB562E5.6040205@siddall.name> I am continuing my quest to get pulseaudio-equalizer to work on thin clients and am almost there. I set sound=false on the clients then fire up pulseaudio as a localapp which autostarts when the user logs in with this command: ltsp-localapps /usr/bin/pulseaudio -n \ --exit-idle-time=-1 \ --high-priority \ --log-target=syslog \ -L "module-esound-protocol-tcp auth-anonymous=1" \ -L "module-native-protocol-tcp auth-anonymous=1" Then I can run pulseaudio-equalizer-gtk as a localapp and adjust the equalizer. Excellent! The only issue I still have is that pulseaudio on the client when started with ltsp-localapps is not given realtime priority so the audio can get choppy. I can see the pulseaudio daemon requesting RT but getting permission denied. Back in Fedora there used to be a pulse-rt group that you had to add the user to to make this happen but that no longer exists in SL6. One ugly option I suspect may work is to setuid on the chroot pulseaudio binary but is there a cleaner way?

At least these two meeting apps are doable. Unfortunately the GoToMeeting plug-in HAS to work,,as this is contingent on the vendor 'invite'. It isn't the clients choice. Most of ,,especially high-end vendors ,,for whatever reason,,have chosen GoToMeeting as there online fix-it shop:) Hope this makes the post a little more sense? Sidenote: I/We have actually been using BigBlueButton which works great for our school environment. If anyone on list wants a nice scalable 'show me how' interface, to teachers for example this is very much a realistic approach. It is relativly easy setup for Centos 5 now and very easy if you are running Ubuntu Most teachers don't want to learn anything new,,so this collects a lot of dust,bottom line:) Take Care, Barry From monteslu at cox.net Sun Nov 6 19:08:11 2011 From: monteslu at cox.net (Luis Montes) Date: Sun, 06 Nov 2011 12:08:11 -0700 Subject: [K12OSN] GoToMeeting client In-Reply-To: References: <1320586395.16573.41.camel@localhost.localdomain> Message-ID: <4EB6DB1B.3050900@cox.net> This also won't help with GoToMeeting, but I've been using Google+ in Linux to do Hangouts with audio and video.

I was going to try the Google Chrome suggestion, Downloaded the available rpm,,from the GC distro center,,but unfortunately,,there is not a working version for CentOS 5.x?. I did find a link were someone had tried to manually compile GC on a centOS 5.x build and linked it up,,as an binary. tried this and GC will in fact open from this tar.gz binary but,,it is badly broken in regards to adding the necessary plugins/extensions,etc. So,scratch that idea for CentOS 5.x. It is suppose to install fine via the rpm,,in EL6 from several postings. It appears the glibc stuff is way too outdated in CentOS 5.x to support GC? I have also noticed on most of the sites that really hangs the TC,,is xulrunner,,always throws 'unresponsive script ' errors. This also happened within the firebug plugin for Firefox,,which I did uninstall,just to see if the Firebug parsing the webpage(s) was in fact part of the root cause.

All machines involved are Linux, a little walk in the building at least solved the gateway problem, now all machines see the bridged network as gateway, 172.***.***.***. As a consequence now none of the laptops or pc's can access the outside world, they can only ping the internel NIC, aka the bridged network interface. The Thinclients boot fine and they work ok, but yesterday I crashed the whole network when wanting to assign fixed ip adresses to printers and restarting dhcpd.....

Ultimately PXE booting doesn't seem to be working for me. I loaded two VMs with RHEL6.1 and pulled down the latest updates, then I followed the Install Guide [1] without issues. The ltsp-server-tweaks didn't function for me, but in reading through the mailing list it looks like this can be over looked (at least temporarily). Per the instructions I configured ltspbr0 and tried to PXE boot the VM which is acting as the thin client... no luck. My config is just two VMs for testing purposes. I receive the following error: PXE-E51: No DHCP or proxyDHCP offers were received. On the server I have two NICs, one giving internet access and the other for TCs.

I went ahead and rebooted my server, then tried to PXE again. No dice.

In my case, I'm not using the LTSP server as the DHCP or network router/nat; my clients are on my internal network just like any other host, receiving dhcp addresses from my network's existing DHCP server.

This new bridge that you must create must not have any IP address. It exists only for VM's to connect to each other. * Then the PXE client VM must connect to that new bridge. If you set this up properly, then server VM's ltspbr0 connects to the virt host bridge, and the PXE client VM can also connected to that same bridge should be able to DHCP and PXE boot.

After the initramfs inside the chroot is regenerated, run ltsp-update-kernels ON THE HOST which copy from your chroot's /boot to your tftp directories. If you get this working, could you write a short guide on how you did it? This would be great for others in the community to learn how to customize their own boot images.

Jeff ---------- Create a new plymouth theme. You can do this by making simple variations on the stock theme by taking a copy of the default theme using the procedure below. You can replace "newtheme" in the commands below with whatever name you want to give the new theme. This procedure assumes the chroot is in the /opt/ltsp/i386 directory. Start by copying the folder with this command: cp -a /opt/ltsp/i386/usr/share/plymouth/themes/solar /opt/ltsp/i386/usr/share/plymouth/themes/newtheme Now modify "newtheme" as appropriate. First go into the new theme directory by typing: cd /opt/ltsp/i386/usr/share/plymouth/themes/newtheme Then rename the .plymouth file by running: mv rings.plymouth newtheme.plymouth Edit the .plymouth file and change: Name=Rings to: Name=Newtheme and change: ImageDir=/usr/share/plymouth/themes/rings to ImageDir=/usr/share/plymouth/themes/newtheme You may also want to change the background colors. BackgroundStartColor is the color at the top of the screen and BackgroundEndColor is the color at the bottom of the screen. Plymouth will make a gradient of these colors across the screen. For example to make the background change from white to black change the lines: BackgroundStartColor=0x080808 BackgroundEndColor=0x080808 to: BackgroundStartColor=0xffffff BackgroundEndColor=0x000000 When finished making changes save the file. Next replace the image file named header-image.png with the desired replacement. Do not change the name of this file! The exact size does not seem to matter as the plymouth will center it in the screen above the animated "rings". You can also get fancy and replace all the other progress images also. Chroot to the client directory by running: chroot /opt/ltsp/i386 Activate the new theme with this command: plymouth-set-default-theme newtheme Note: you may get an error from sed (ex: sed: warning: failed to set default file creation context to unconfined_u:object_r:usr_t:s0: No such file or directory). This does not seem to cause problems. Build a new initramfs file with the new theme: ltsp-rewrap-latest-kernel Exit the chroot by typing: exit and update the tftp directory with the new initramfs by typing: ltsp-update-kernels If you use NBD you will also need to run: ltsp-update-image Now fire up a client and enjoy the new theme!

The "fat mode" clients I loaded an OS and statically assigned it an IP address within the 172.31.100.x range.

Any response is welcome, especially those which validate that some of the testing I've done already were the right paths to head down. > On 11/24/11 5:45 PM, Warren Togami Jr. wrote: >> Hi Shawn, >> >> Your attempt is complicated substantially by running the LTSP server >> within a VM. >> >> * The interface that you attach to ltspbr0 in the server VM needs to be >> a secondary virtual eth device, not the primary that the VM uses to >> reach the Internet. Correct. On my setup eth0 leads to the public internet, whereas eth1 is private. >> * Then on the VM host, that secondary virtual eth device needs to attach >> to an entirely separate bridge that probably doesn't already exist on >> your system. This new bridge that you must create must not have any IP >> address. It exists only for VM's to connect to each other. I created a new virtual bridge (virbr1) which just allows communication between guests attached to it. So far so good. When the LTSP-Server and another VM are attached to this they're able to ping each other, so it looks like the comms aspect is OK. >> * Then the PXE client VM must connect to that new bridge. For this I assigned the secondary interface of the server (for me, eth1) to virbr1. >> If you set this up properly, then server VM's ltspbr0 connects to the >> virt host bridge, and the PXE client VM can also connected to that same >> bridge should be able to DHCP and PXE boot. Still no luck on my side, even after reloading the LTSP Server and starting anew. I'll have access to physical hardware later this week to test things out on. Also, it seems like many more people have had this deployed on RHEL5 whereas I'm on RHEL6. Any chance this could be causing issues? Thanks! Shawn
