RE: Cross-platform virtual meetings

[Bryan O'Neal]

I have loved this thread so far!  What I can tell you we did was
Skype: Voice/Chat/Video
Yugma: Presentation/Desktop Sharing/PSTN Voice Conferencing

The down side to Skype is that only two people can video conference and for
voice only I have found my clients are more comfortable with the old
fashioned dial in voice conference call provided with Yugma.

Yugma on the other had was great for presenting and collaboration.  With the
ability to pass control around or even switch presenters mid session so any
one who wants can show their screen and present their ideas and invite
others to take control for tweaking I have never found a better solution for
online meetings.  Plus the price can not be beet. Free for the basic edition
and something like $15 a month for the pro version.

Check it out at www.yugma.com you get the pro version free for 30 days.
After that your on the basic plan until you pay so there is no risk.

Subject: Cross-platform virtual meetings

My company is in the process of trying to set up virtual meetings, including
things like screencasting/sharing, voice, video, whiteboard, etc. The office
is all Mac, our clients are mostly Windows, and I'm on Linux. We've been
trying to find something that will work for everyone and is easy to use, but
so far haven't come up with much. Webex seems to work, but I can't get
screen or document sharing to work from Linux, and it also lacks voice. Most
of the others either didn't run at all or don't have any Linux client.

Recently I set up a VNC server on my machine and used our VPN to broadcast
back to the office and Skype to handle the audio. It worked, but not well,
and it's definitely not something that we can use with our clients.

So, fellow Linux users, got any other suggestions for what I should be
using? I'd settle for something that didn't have voice if everything else
worked really well, but of course, I'd like to have everything in one
package.

This is describing installing PCLinuxOS as a virtual machine inside a
working Ubuntu-VirtualBox setup ... which doesn't seem to have
anything to do with trying to get my installed PCLinuxOS system X
recovered.

The article says: "Guest Additions installs from a CD iso file.

I don't have any CD iso for this.

The article then says: "So, we need to load the iso as a CD in our
virtual machine.
For this, the virtual machine must be shut down (powered off)."

There is no way I can do this when my basic machine is not working.

Virtualbox does a kernel recompile thing.

RE: How to recover X display?

[Lisa Kachold]

Sorry, I should have extracted the solution and made it big and bold (I forgot 
your system just got downgraded at an Installfest, and you are PTSD stuck!)

This will fix her:
Reinstall Virtualbox Guest Additions from the terminal:

http://www.informit.com/articles/article.aspx?p=1271263&seqNum=3


Install VirtualBox as described Part 1 and Part 2
of "Sun VirtualBox (xVM): A Virtualization Environment for Linux"
article.
Of course, if you had Xterm you could just do:
 

Next: Virtualbox Console > Devices > Install Guest Additions
There is a script somewhere hereabouts:
cd /media/VBOXADDITIONS_2.0.6_39755 [directory name will vary with the version]

sudo sh ./VBoxLinuxAdditions-x86.run [or -x64 if running a 64-bit guest]

Other stuff probably not related:
http://www.virtualbox.org/wiki/User_FAQ

Just FYI, the problem is that you upgraded to a new kernel, so you had to 
recompile or reinstall your graphic drivers .

Updates between versions are sometimes a lottery! 

Let's look at how we must package a problem for the PLUG:  We follow these 
steps (dumping into email):

1) What is it (versions, etc)?  
2) What is she whining about (Linux like any good partner will tell you very 
clearly what is the issue)?

[Ignore my installation references for Ubuntu's Virtualbox (they are just 
info); but possibly an update to the ABI module or v41 module were done during 
the installation?]

Check the file creation date for your Grub at /here/boot/grub/menu.lst
Check to verify what she is currently booting there - look for backup files and 
diff.

Discussion:  
http://www.pclinuxos.com/index.php?option=com_smf&Itemid=26&topic=54523.0

We might logically research the exact Xorg errors for these, spoze?

3) Research our error for known solutions:

module ABI major version (1) doesn't match server's version (2)
failed to load module "v41" (module requirement mismatch,0)

4) The Zen of Troubleshooting, "The error is the problem"

Looks like you have a kernel module mismatch grasshopper.

No!!!

You failed to see the recommendation (for repairing these exact errors) at the 
bottom of the on the last LINK.

These linked URL's are all part of the solution process, we don't just drop

Cross-platform virtual meetings

I pitched something like this for the CentOS GSoC application 
-- see:  http://wiki.centos.org/GSOC/Projects at
Reference VVW Squawk Box
as I am pretty sure that FOSS space does not have a nice 
bundel doing all this (although the pieces and parts seem to 
be all pretty well done).  As the CentOS project was not 
selected in last week's round of projects, we'll not have an 
intern working this issue

BUT,  nothing says doing the further task decomposition and 
implementation has to be a GSoC project, though

Re: Cross-platform virtual meetings

[Joe]

Adobe's Connect Pro is CRAZY expensive, so we're not likely to use it.

Using icecast is an interesting idea. I wasn't aware that icecast
handled video, it's been a while since I've played with it. I'm not sure
how easy it would be for our marketing dept. to set up though.

Coccinella looks pretty cool, but we need something that does more than
a whiteboard. The idea was to use this both for internal conferences
(they're in Chicago, so I need an easy way to demo things with them) and
for external sales efforts (seminars and presentations to clients around
the world). Openmeetings looks like it has both voice and screencast
modules. The only downfall being that the client has to install the
application, but it may not be that big of a deal.

Thanks for the feedback. Openmeetings looks really cool, assuming it
works well.

I've used Coccinella before, it's really nice. Written in TCL/Tk, and it
can work with pretty much any jabber server (except Google Talk for some
reason, when you try to use VoIP). It worked fine on Linux and Mac OS X
for me.  Whiteboard is shockingly instant in all of my trials. I'm
currently trying to get my school to switch to that from Elluminate.

Oh, Elluminate. It's quite possibly the WORST software I have ever used,
next to some of the things Adobe has put forth. But, the client does run
on Windows, Mac, and Linux, although I've never got sound to work
reliably on Linux. The tech support won't help you much either. They say
that they will only support Red Hat and SuSE. I guess that's not a
problem if you are familiar enough with Red Hat or SuSE and can
translate their instructions into $YOURDISTRO lingo. I'll include their
link just to be fair. (If you're interested, I wrote an AppleScript that
can go to any room it pleases ;)

http://coccinella.im/ <-- Try that!
http://elluminate.com/ <-- Shun!

Some things that I have tried that work cross platform, mostly because 
they run in a browser:


ustream - http://www.ustream.tv - works well for one-to-many broadcasting
mebeam - http://www.mebeam.com - multipoint conferencing
stickam - http://www.stickam.com - multipoint conferencing

Joe -
If you get more than a few folks into a meeting you want broadcast not
conference ware - icecast will broadcast audio & video, good for a
group that doesnt need to interact in channel. Pair icecast with an
Asterisk VoIP conference for audio feeedback and you should be able to
handle a good size group.

using? I'd settle for something that didn't have voice if everything
else worked really well, but of course, I'd like to have everything in
one package.

Mount it manually, then.  Plug drive in, dmesg | tail to see which
device node it got assigned to, mkdir /mnt/usb , mount /dev/sd?1
/mnt/usb .  (It's not that you can't copy files to the disk, it's
that you don't know how to do it.)

No scare quotes around X are necessary.  It's an abbreviation for 
the X11 Window System, which drives graphics cards and input
devices on Linux/*BSD systems.  You probably have an executable
called /usr/bin/X on your system.

> Tried editing out the line referring to "v4l" and rebooted, but
> that did not bring back "X"

No reboot was necessary.  Just restarting X should've showed you
if it had worked.  Did /var/log/Xorg.0.log change?  It
would be a good idea to post that file too, since there are
probably some things in there that would be useful to see.  The
whole file, not excerpts, even though 90% of the X log is usually
useless

> VGA compatible controller: ATI Technologies Inc Radeon Mobility

Right, so the xorg.conf grep should've showed either radeon or fglrx.
Those are the Free and proprietary X modules that drive those cards.

This is all very strange to me, since installing virtualbox shouldn't
have changed *anything* with the X config.

Joe -
If you get more than a few folks into a meeting you want broadcast not
conference ware - icecast will broadcast audio & video, good for a
group that doesnt need to interact in channel. Pair icecast with an
Asterisk VoIP conference for audio feeedback and you should be able to
handle a good size group.

Re: Cross-platform virtual meetings

[Joe]

Thanks for that, I had no idea Adobe had anything like this. The only
downfall is it's limited to 15 participants at a time. Their Connect Pro
solution might work though, I don't see anything about a participant
limit. They don't have pricing for that online though, which leads me to
believe it's pretty expensive. Still, thanks, we'll check that out!

Cross-platform virtual meetings

[Joe]

My company is in the process of trying to set up virtual meetings,
including things like screencasting/sharing, voice, video, whiteboard,
etc. The office is all Mac, our clients are mostly Windows, and I'm on
Linux. We've been trying to find something that will work for everyone
and is easy to use, but so far haven't come up with much. Webex seems to
work, but I can't get screen or document sharing to work from Linux, and
it also lacks voice. Most of the others either didn't run at all or
don't have any Linux client.

Recently I set up a VNC server on my machine and used our VPN to
broadcast back to the office and Skype to handle the audio. It worked,
but not well, and it's definitely not something that we can use with our
clients.

So, fellow Linux users, got any other suggestions for what I should be
using? I'd settle for something that didn't have voice if everything
else worked really well, but of course, I'd like to have everything in
one package.

As far as I can tell, "X" did not get upgraded or changed.

I would do that, but I have to copy that file off of the broken system
as I can't use a USB flash stick .

Re: Anyone Played with OpenQRM?

[Mike Schwartz]

OK, I edited that wikipedia page, to add a link saying

where that hyper link points to the URL
<< http://www.openqrm.com/ >>

By the way, one of the previous replies in this PLUG-discuss thread, seemed
to (accidentally?) change C to Q:

> http://opencrm.org OpenCRM [...]

instead of

> http://openqrm.org OpenQRM [...]

Was that just a TYPO?  ...because, I don't think we are [intentionally]
changing topics in the middle of this thread... (right?)

Re: One of those (few) days that GRUB sucks...

[Joe]

I usually boot a rescue disk and do the following commands.
chroot /mnt/sysimage/root_parition (Fedora mounts the drive under 
sysimage, and you need to mount the root partition)
( After the chroot, you may also need to mount the /boot partition)
mount /proc
mount /sys
grub-install /dev/drive ( where drive is the boot disk)
umount /proc /sys
exit
reboot

This is an X problem IIRC.  The module being referred to is the X
module, not a kernel module.  Did X get upgraded at some point?
The thing that's messed up is /usr/lib/xorg/modules/drivers/v4l_drv.*
AFAICT.  If you have any reference to v4l in your xorg.conf , then
edit that file and comment that line out.  Your webcam and/or TV
tuner will stop being able to use XV, but you'll get X back.  Also,

grep Driver /etc/X11/xorg.conf
lspci | grep VGA

...will tell you which X module you're using and which graphics
card you have.  In fact, you should take your xorg.conf and put
it on your website somewhere, then follow up with a URL here.

XFdrake... something Mandrake-specific?  Gah, most of these tools are
rather poorly debugged.

> Should I try to remove all files on the system pertaining to virtualbox?

This shouldn't have any effect on anything, but sure, try your distro's
equivalent of "yum remove virtualbox".  FWIW, I installed virtualbox
on my Thinkpad T42p a while back, and never had any problems with it
horking up suspend-to-RAM or doing anything weird to X.  Then again,
I'm using Gentoo, and YDistroMV.  HTH anyway,

SABnzbd+ is pretty good, it uses a web interface and checks your newzbin
account for bookmarks automatically so there's no need to manually d/l
the nzb files, it's got a pretty cool firefox plugin too.

Re: How to recover X display?

[Josef Lowder]

Thanks for all your suggestions.  I've tried to follow-up on every one,
but still haven't been able to solve the problem.  Perhaps I'll just have
to reinstall and risk losing my data as I don't know a way to get it copied off.

As previously reported, the Linux kernel booting is: kernel.h-2.6.18.6
dated Feb 23, 2007 and /boot/vmlinuz is dated Apr 6, 2007
None of this changed as a result of installing virtualbox.

As previously reported, there has been no change in the grub menu.lst.
It also is dated Apr 6, 2007.  There are no backup or previous version
files for this, so nothing from which to 'diff' compare.

> We might logically research the exact Xorg errors for these, spoze?

As previously mentioned, I did this and found only two reported errors
as listed below.

I have searched the 'net for any info about how to resolve these two
reported errors, including the two links you provided, and have seen
a few corresponding references, but still haven't found any way to
correct these two errors.  ("v41" above should have been "v4l" --
lower case letter "L" not the number one "1")

You are no doubt correct, but how might one correct this problem?

Linux boots up fine, but without any "X" graphical access, just a
blank screen.  I can switch to terminals 1 thru 6 and they all work,
but when I type 'startx' the response is: "Cannot access the X server."

The problem seems to pertain mainly if not exclusively to the X server.
I tried running '/usr/sbin/XFdrake' and it seems to show that everything
is set correctly.

Should I try to remove all files on the system pertaining to virtualbox?

Re: Usenet readers/binary downloaders for linux

[Joe]

I was using hellanzb for a while when I was doing binary downloads via
nzb files. It's not a GUI though, but it was easy to configure and
worked incredibly well! I was using a GUI reader to grab the nzb files,
but I don't remember which one it was. Looked like xpn but I don't know
if that was it. Thunderbird would probably work just as well though.

Well, I burned an LFS CD, GRUB(ed) the drive AND the partition and still the 
same problem...   :(
Does anybody have a gun?

One of those (few) days that GRUB sucks...

[kitepi...@kitepilot.com]

History:
I have a running machine,
I booted it up with KNOPPIX,
grabbed another hardware-wise fairly current "empty" machine,
booted it up with the same KNOPPIX,
rsync(ed) [-aH --super] one HD to the other,
ran GRUB,
root (hd0,0)
setup (hd0)
and I got a perfect clone running.
So far so good... 

I did this as I have done it 7368269 and-a-half times before for the last 
few years... 

S...
Then I spawned another machine the same way and configured them to act as 
server and a client.  They have worked fine and they work. 

Then I need to duplicate this 2 machines.
Well, easy, I've done it millions of times, haven't I?. 

Not this time...
One machine hangs on:
GRUB Loading stage1.5(GARBAGE-GARBAGE-GARBAGE)
The other one just scrolls the screen endlessly...   :( 

I have tried every trick I know, I checked the partitions boot flag, I 
md5sum(ed) the files and they are not corrupted, GRUB doesn't give me 
otherwise any errors, and I am at the end of my rope... 

FWIW, I saw something like this before and I fixed it with a newer copy of 
GRUB, but being this an old RedHat in really OLD hardware, I'm getting me 
this time and OLDER copy of GRUB. 

Ideas?
Thanks!
Enrique
