Michail,
Thanks. Wad pointed me to "J3" which was the white (b) choice in my last
query. It took a while,
but managed to snap on the pig tail to the 8388 board.
Next, and this is perhaps a question for Bryan or Wad,
What mode do I want this antenna in when it is attached to the XS server?
I looked at the link
Michail pointed to below, and it seems there are two options "fixing" it
and "upgrading" it, and
the two procedures are quite different.
Currently, when I boot the XS with the AA plugged in, it is not detected.
When XS is up and running,
and I unplug-and-replug the AA in the USB port, I get a one line message:
# audit(1203037547.511:3): dev=msh0 prom=256 old_prom=0 auid=4294967295
The prompt doesn't come back until I hit ENTER.
Can you tell me specifically which portions or methods of the
"reprogramming" I need to do
for our OLE-Nepal XSX test?
Thanks

Re: [Server-devel] Spreadsheet, Active Antenna, and this weekend
Tony.
What you got, is the 8388 development board (which is functionaly
equivalent to the active antenna).
It comes with an external antenna and a pigtail. It should be fairly
obvious how to connect the antenna to the pigtail and the pigtail to the
board.
After that, all you have to do, is to plug the module into a USB port of
the "schoolserver" machine.
Please note that the firmware on the module, self boots into mesh repeater
mode (hence the term "active antenna") when the module gets powered and
the host doesn't try to download firmware to it.
In practical terms that means that during reboots of the server the module
will not be properly enumerated and will have to be removed and be plugged
in again with the server fully running.
The wiki page http://wiki.laptop.org/go/Active_Antenna_Reprogramming has
instructions on how to change the modules boot2 code so that it doesn't
autoboot when attached to a server.

[Server-devel] Spreadsheet, Active Antenna, and this weekend
Team,
I have gotten my active antenna from OLPC. As soon as Julia or Michail
provide me instructions
on how to put it together, I can begin mesh testing.
My current test configuration is:
(internet)---(cable modem)---(Hub with WiFi)---(XS) ---Active Antenna--XO
If necessary, I can try to get a second box to act as proxy, and some
additional NIC cards and
cross over cables. Let me know if that is required, or if the tests are
valid with the configuration above.
Another option is that I can use my one box in two configurations.
(internet)---(cable modem)---(Hub with WiFi)---(Squid) ---Active
Antenna--XO
This would mean testing the Squid box by itself, and the XS by itself,
for those testcases focused on one or the other. I will pull one of my
other
PCs out of the closet, and perhaps get that one to be my second box.
SJ> You mentioned OLPC are doing mostly in Python. While all of the XO
client code is in Python, the
XS server code, driven by Moodle, is in PHP. And I have received some
sample PERL scripts for
the install from mis amigos en Uruguay. I am agnostic to languages, but
would like to think we standardize
to Python for client, and PHP for server side code for now.
Greg>
As for backing up the /home directory from the XO to the XS, I was
envisioning a PHP page on the
server that the student could navigate to, and this would perform the file
upload. It would require the
students to take action to cause this to happen. It sounds like an
automated solution would be better,
but how did you want this to be kicked off, once per day?
Brian>
I am looking at the spreadsheet you sent. On "Software" I think you
should add Fedora level, especially
if Wad upgrades from Fedora 7 to Fedora 8, and also Linux kernel level. On
"Content" can you provide URLs
for all of these besides "Wikipedia.org" I know, but the others? Do we
have "OLPC Library Content" to
test with? What were you looking for under "Space Used"? Did you mean
memory RAM used, or
disk MB used? Please clarify.
My thoughts on the Test Cases:
"Apply image to XO from USB" -- I have my developer key, but was under the
assumption that most XO
do not have a developer key? Do you want me to test this process with and
without developer key?
I need instructions on how to do "Apply Image from USB" as I have never
done this before, and which
images (I am running 653 now) you want me to test.
"Chat with Other XO" -- Ok, to test chat before, I used my Thinkpad T60
running QEMU using
the website "xochat.org" to connect with my XO laptop. If we have
ejabberd running on the XS, would
I connect my laptop and XO to "ejabberd" and have the XO over the mesh,
and the Thinkpad over
the Wi-Fi? If not, I will need to borrow my friend's XO for a pure
mesh-to-mesh test.
"Can launch Squeak Activity from Moodle" -- is this the same as eToys, or
did you mean the
developers version of Squeak on the OLPC website?
"Fill up the XOs hard drive" -- I love this one. In general, I think we
should also develop some
tools that generate activity, this would help identify memory leaks and
what logs needs to be
tailed over time.
"Remove activities manually" -- what does this mean. I have been able to
add activities to my
XO by downloading the XO files to my Journal and installing them, but the
only way I have been
able to remove them was dropping down into "Terminal" activity and hacking
away at the file
trees with "rm" commands. Is there a better way to test this?
"Type in Nepali, Save text in Nepali" -- as I mentioned before, Nepali
text does not appear
properly on my XO. I had set up this test page (
http://www.990tony.com/olpc/index.php)
which shows correctly on my Windows XP with both English and Nepali
script, but on my XO
the Nepali script shows up as little black-and-white rectengles. Is there
an image I need to
install on my XO to be able to read both English and Nepali script?
Thanks
