is an exellent report. The questions I can answer I have answered below; I'll
let others chime in to answer the rest. This is also great feedback on the
installation process and what information you needed to get through it.
We'll work on making it simpler this week!</FONT></SPAN></DIV>

<P><FONT face=Arial size=2>Had the problem mentioned earlier today where I
could not switch rooms in TVS and attributed it to something I did (nothing
ever works the first time - right?). It was getting late so I decided to
troubleshoot later. Hopefully the rebooting of TVS cleared my
problems.</FONT></P>
<P><FONT face=Arial size=2>Anyway here are some comments/questions that maybe
someone can shed some light on and/or might be helpful to others...</FONT>
</P>
<P><FONT face=Arial size=2>0). I believe I saw somewhere that RH7.3 was
supported/tested, etc for v2.0RC1. However I had problems trying to install
the prerequisite version of the Python2 RPM linked to from the AG2.0 website.
This version indicated it was for RH8.0 and when trying to install it
indicated a dependancy on libc.so.6 (glibc3.2) and libdb.4.0 (Berkley DB
support?). Since I verified that I already had a version of Python2 loaded,
and libc.so.6 was linked somewhere, I skipped installing this version with the
thinking that updating gcc, glibc at this time was not a good idea. Is the
version of Python2 important?</FONT></P>
<P><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>This is something we need to clarify. On RH7.3 Python 2.2.
is already installed, so you need not install a new
python. </FONT></SPAN></FONT></FONT></P>
<P><FONT><FONT face=Arial><FONT size=2><SPAN
class=754120811-23052003> </SPAN>1). Had a problem with the order of
installation of the AG rpms on the Audio & Video machines. Received an
error installing AccessGrid-2.0RC-1.i386.rpm (something about processing the
$pre commands/section - not exactly sure since I do not have my notes),
however trying to install the respective services (Audio/rat or
VideoProducer/vic) did not work since there appeared to be a dependency on the
AccessGrid-2.0RC-1 rpm. Putting all packages on the same rpm install command
line allowed the respective services (Audio/rat or VideoProducer/vic) to
install, however the AccessGrid-2.0RC-1 section still produced that $pre error
mentioned earlier, however I could now issue the command to install just the
AccessGrid-2.0RC-1 rpm.</FONT></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>I'll let Tom Uram or Ti Leggett answer these questions;
they are more familiar with the details of the Linux install
process. </FONT></SPAN></FONT></FONT></P>
<P><FONT><FONT face=Arial><FONT size=2><SPAN
class=754120811-23052003> </SPAN>2). I generated the globus key/cert
request on just one machine. When I received my cert back I then copied this
(and the corresponding key) to the appropriate directories on all nodes. Not
sure if this is good form, but it seemed to work. (Grid proxy init did not
give any errors).<SPAN class=754120811-23052003><FONT
color=#0000ff> </FONT></SPAN></FONT></FONT></FONT></P>
<P><FONT><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>The process of requesting certs should get only easier (it's
hard to go down from the bottom), we're working on software that should make
this significantly more clear. Until that comes this little bit might
help:</FONT></SPAN></FONT></FONT></FONT></P>
<P><FONT><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>In AG2.0, the certificates we focus on</FONT> <FONT
color=#0000ff>are identity certificates. These are designed to identify an
individual. Therefore, you should be able to get your identity certificate
anywhere and as long as you keep your usercert.pem safe you should be
able to use that on all the machines. You have to copy it to all the machines
you want to use that certificate on if you don't have a shared home file
system, which is a bit tedious.</FONT></SPAN></FONT></FONT></FONT></P>
<P><FONT><FONT face=Arial><FONT color=#0000ff size=2><SPAN
class=754120811-23052003>Later we'll talk about other certificate types,
service and host, and how they can alleviate some of these
issues.</SPAN></FONT></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2>3). I do not have all my notes in front of
me, but if I recall correctly, the response I received from the proxy init
indicated that it was valid for only a short period of time. Is this normal?
How often must the proxy be updated<SPAN class=754120811-23052003><FONT
color=#0000ff> </FONT></SPAN><SPAN

<P><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>The default is 8 hours. On Linux this can be changed
with the -h (hours) argument, wgpi.exe has an entry for changing the
number of hours in the UI. I believe we are now building and
shipping grid-proxy-init.exe for windows and trying to move away from the
wgpi.exe tool. In fact, in the latest code if your proxy isn't valid a
dialog pops up that shows your DN, asks for your passphrase, and lets you
input the number of hours you want your proxy valid
for.</FONT> </SPAN></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2>4). A message is generated on the Audio &
Display machines when running AGServiceManager about looking for/needing to
run SetupVideo.py. I did not install the VideoProducer on these nodes,
so I don't think this file is present. Do I need to be concerned? Can I
configure the ServiceManager to not look for SetupVideo.py on the Audio &
Display machines?<SPAN class=754120811-23052003><FONT

this question.</FONT> </SPAN></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2>5). My (and other) video streams did show up
in the TVS lobby after starting the VenueClient : ) and each of my
video streams showed the configured label of Audience, Main, Presenter, etc.;
however they all appeared to be coming from ag@xxx.xxx.xxx.xxx (video capture
machine IP address). How do I configure the different streams to show my
institution name instead of the IP address?<SPAN

<P><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>Again, Tom Uram :-).</FONT> </SPAN></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2>6). Finally, something that's been bugging me
in v1.x & now 2.0. How can I scroll through all received streams in a
venue on the display machine? I know to use the number key to change the
number of streams horizontally, but how do I scroll/display them in the
vertical direction?<SPAN class=754120811-23052003><FONT
color=#0000ff> </FONT></SPAN></FONT></FONT></P>
<P><FONT face=Arial><FONT size=2><SPAN class=754120811-23052003><FONT
color=#0000ff>This is a characteristic of the tool we're using. It doesn't
have this feature. We'll be working on building some </FONT> <FONT
color=#0000ff>alternative tools (and working with others to have them build
some) to allow a wider range of solutions, but specifically if we use
OpenMash's vic tool it does a couple of things nicely, first it has a 's'
command key that turns on scroll bars in the thumbnail view (yay), and it also
has automatic detection of blue/black video streams and the option of not
displaying them. Further, it has the ability to have the autoplacement of
video streams be programmatically modified (using tcl --ick). However, the
biggest drawback is that it doesn't have autoplacement working the way our vic
does yet.</FONT></SPAN></FONT></FONT></P>
