How do I clear an OFW flag?

2009-01-02 Thread Martin Langhoff
Trying to test the fix for #8976 , I am stumped at what I thought
would be a trivial step - clearing the AK flag. My laptop has ak and
dk flags set, and I have both leases handy in case something goes
wrong. The NAND has a good signed image.

The only hint I was able to find was in a script in
http://wiki.laptop.org/go/OLPC_Ethiopia/XO_reflash_process - but I'm
not sure how to safely/sanely remove the flag without bricking this
nice XO.

So far the plan seems to be...

  unfreeze
  ???
  profit!

any hints?

cheers,

Re: UDP broadcast from an XO

2009-01-02 Thread shivaprasad javali
Hi,
   Is there any way I can ask the OLPC to broadcast the UDP packets. I am
broadcasting the UDP packets by writing to the UDP port and setting the
destination address to 255.255.255.255 . I am using ports 61556 and 61557
for communication. So if the antenna of the OLPC ( and hence its wireless
connectivity) is functional wont it broadcast the UDP packets it receives
for broadcast?

Thanks

 Can you show me one of these UDP packets?


 remember that broadcast packets don't generally go through routers (they go
 through bridges, but not routers)

 so if the two XO's are on different subnets, broadcasts won't be seen by
 the other one.

Re: Problems with Adobe Flash player on the XO.

2009-01-02 Thread Carlos Nazareno
Hi Stan!

 I'm having problems:  Adobe FlashPlayer doesn't detect the XO's built-in
 webcam so it can't transmit video out to the Internet on Flash-enabled
 web sites,

I've documented this problem as well at
http://wiki.laptop.org/go/Adobe_Flash - The XO's webcam is not
interfacing properly with Adobe Flash 9  10. Adobe's done a lot of
work towards getting cameras in various Linux distros working with
webcam enabled-Flash apps, and they finally got V4L2 running last
year, but apparently the XO is using some kind of not-as-common
chipset/software combo (in 8.2.0 I think the OS is using a weird
mishmash of old  new software/drivers because of problems with the
cam in the webcam activity on newer drivers?).

I got in touch with some Adobe guys last year before Flash Player 10
final launched about Flash's webcam interfacing problems on the XO,
filed the bug report, followed their instructions and submitted the
hardware info gathered from the data-gathering tool at Penguin.swf's
(Adobe's official Linux Flash dude) blog:
http://blogs.adobe.com/penguin.swf/2008/07/paparazzi_v2_1.html

Anyway, I haven't heard a word from the Adobe folks yet as I guess
that was a very busy time for them with Flash 10 final release going
out the door at the time, the report probly got lost in all the
hubbub. Anyway, I'll try following up with them as I'd like to play
with writing some Flash webcam toys that would work on the XO myself.

I can't get Flash to activate the
 XO's camera... ...This was while running on the XO's Browse activity.

The camera works with the Browse Activity, just not properly (the
camera turns on and it displays red  green static that reacts to
objects waved in front of the camera)

  I thought
 that maybe Opera for the XO would do better.  No luck.

Yup, Same as with the Browse Activity. XO's weird camera
chipset/software combo interface still hasn't been fixed with the
linux Adobe Flash 10 plugin.

 Opera as installed from the wiki.laptop.org/opera instructions does not even 
 play
 the Flash on the Adobe web site nor any other Flash embedded in a web page.   
 All that Opera shows is a
 gray rectangle where the Flash should be, no text saying to click to
 play the Flash.

As documented in the Adobe Flash wiki:
http://wiki.laptop.org/go/Adobe_Flash and Adobe Flash
The official Opera Activity is based on Opera 9.12 and it isn't
compatible with Flash 10. The newest Adobe Flash plugin compatible
with it is an older version of Flash Player 9.

Newer non-Sugarized Linux desktop versions of Opera like 9.63  latest
work fine and dandy with latest Flash Player 10 final. Again, you're
going to have to use the Terminal (type opera at the prompt) to
launch Opera.

 I submitted a comment to the Opera programmer who maintains the Opera
 blog about the OLPC version, but that blog has had very little activity
 in the past year so I'm not hopeful of any results from the Opera
 people.

Ditto. I've tried Sugarizing newer versions of Opera myself, but we're
out of luck because of the Rainbow Security implemented in newer XO OS
builds don't allow writing of files by Activities to certain
directories that Opera installs to. The Opera dudes will have to
create a special OLPC Opera Activity for us like with 9.12 since Opera
is not open sourced and we won't be able to do the proper
modifications for Rainbow Security compatibility ourselves.

 Has anyone here tried to run a recent release of Opera on the
 XO, not the very old version that was customized for the XO according to
 our wiki?

Runs fine and dandy, you just have to launch it via terminal :) -
Launch Terminal Activity, type opera at the prompt (assuming of
course that you'd already installed Opera). That instance of terminal
will then be inaccessible until you exit Opera. Once you exit Opera,
you regain control of the terminal prompt.

(Yeah Skier, the Opera wiki entries are next on my hit list for
editing: they're due for massive updates :P)

 Even without the 2-way video streaming, www.vyew.com is a nice
 application for collaboration over the Internet.  Try it.

Thanks for the link Stan! I was looking to build a Flash app just like
that, only less ambitious (crud, someone beat me to the punch! ;P)

Cheers!

the normal address to use for broadcasts is nto 255.255.255.255, but the 
broadcast address of the particular network you are on.

for example: if you are on 192.168.1.0 with a netmask of 255.255.255.0 the

2009-01-02 Thread Carlos Nazareno
 Could you be more specific about what writes are failing?

Hi Michael!

Basically the problem is this one from the Opera Wiki page:
There is at present an incompatibility between the Opera activity and
the OLPC Rainbow security system on some builds. If when you launch
the Opera activity, the screen goes blank and stays blank, you have
likely encountered that incompatibility.

 In the past, we've been able to achieve both isolation and a working
 activity (e.g. Scratch) with some easy filesystem tricks...

 Also, have you filed a bug? I've tried searching dev.laptop.org for
 opera rainbow but I didn't find any likely tickets...

My memory's kinda fuzzy, but I think I went straight to the guys at
Sugar Labs then asked over there (web form?)... basically the answer I
got was that we really can't do much about it because the standard
linux desktop version of the latest Opera rpms installs its files to
/etc/ and other system directories, and the new Rainbow Security
system requires that Activities only install and run from /home/
(olpc/ ?) or something like that, and the only way to fix it was to
modify Opera to install/run only from Rainbow-permitted directories
and that's not possible outside of Opera's organization because Opera
is closed-source.

Re: Flash Opera on the XO + Firefox

2009-01-02 Thread Carlos Nazareno
Since Opera's newer releases still won't see the XO's webcam, I won't be 
installing Opera updates until
someone (OLPC people or Adobe) gets the driver situation fixed.  I don't think 
either organization has much
motivation to fix it, though.

Yeah, a shame IMO. The IT world has gone full-circle and if you think
about it, users are now actually shifting back to thin clients kinda
like dumb terminals back before everyone had a personal computer. A
lot of services/applications are shifting to the web and and a lot of
traditional desktop apps can now be run from browsers (thin clients)
especially now because of leaps in dynamic interactivity because of
AJAX and Flash - Rich Internet Applications (RIAs). Microsoft's
windows and office productivity software is now under a big threat
because of this and that's why they jumped onto the cloud computing
bandwagon ;P

Anyway, as such, I'm hoping to contribute more to OLPC as volunteer by
attacking the problems we're trying to solve from a cross-platform
web-based approach rather than being tied down to hardware/software
configurations (which evolve so rapidly that stable locked-down
versions are moving targets that are practically impossible to hit
because of new stuff breaking old stuff all the time), and the camera
is a particularly useful and interesting extension.

Since Flash is now the de-facto installed everywhere interface for
tightly-integrated interactive multimedia (vector graphics, sound,
video, etc - it completely ate Java's originally envisioned browser
niche!), I was hoping we could do more work in browser-contained
sandbox environments (Webcam - Flash).

Anyway, I think Adobe isn't that unreachable regarding Flash + XO cam.
I mean with Adobe's strong support and coordination Flash-wise (Flash
Lite) of less-well known devices (that hold similar geek appeal as the
XO) like the Chumby (http://www.chumby.com/) and iRiver Clix
(http://www.iriver.com/), I think we've got a decent shot at getting a
Flash 10 webcam fix for the lean mean green machine ;)

 However, Opera didn't play nicely with the icons at the top of the
 frame.   There were two circles on the frame when I ran Opera, one of which
 would not go away when I closed Opera.

Oh, I guess I didn't encounter this because after my 2 failed attempts
at trying to modify newer versions of Opera to run sugarized, I did
complete wipes and clean reinstalls of the XO with me. Is your current
Opera installation an upgrade with the latest 9.63 desktop version
installed over the 9.12 OLPC edition? If so that could be causing
it... the un-updated section on upgrading Opera at its wiki page is
now wrong: you will no longer be able to launch Opera with the Sugar
icon on newer XO Builds (8.2.0/767) because of Rainbow Security.

 I couldn't get that icon to go away
 without rebooting (it didn't respond with a menu when I dwelled the mouse
 pointer on it).

I experienced this too when I installed Opera 9.12 OLPC Sugar Activity
edition. Didn't happen to me anymore when I fresh-wiped and installed
the vanilla Opera standard Fedora desktop rpm version.

Off-topic, I'm also experiencing a lot of circle icons that refuse to
die until reboot with C Scott's Sugarized Activity version (0.6) of
Firefox 3.01. Am going to try out latest Firefox non-Sugarized on the
XO and see how it goes.

 Since I don't plan to use Opera until Flash plays in it on the
 XO, I'll just ignore that icon bug.

Oh, Flash plays pretty well enough with Opera, better than with Browse
IMHO ;) It's the webcam that's wonky, and I just recently discovered,
the flash and stuff now refuses to click buttons properly in the Flash
privacy configuration screen (I hadn't played much with my alloted XO
since the Flash 10 beta/XO OS 767 beta days because of work and the
privacy configuration screen was working pretty okay during Flash 10
beta).

 Opera is nice, but I have to use a
 microscope to read some of the text menus because it's not set up for the
 high-resolution on the XO's small screen.

Oh, sorry about that!

*insert developer It's not a bug, it's a feature! joke* ;)

Seriously tho, tiny resolution is more a feature for me: because
everything's being rendered at native resolution with Opera
(everything is so tiny because the XO's real resolution is a
mind-blowing 1200x900), everything is so much faster compared to the
Browse Activity and Sugarized Firefox 3.01 where pages are zoomed in
to make them more readable. (I could be wrong about Firefox -- is it
displaying just larger fonts, Scott, or is everything zoomed in?)

Scaling up/zooming in graphical stuff taxes the processor so much more
because it's actually resampling and upscaling content and has to work
even harder because it's now rasterizing more pixels.

Anyway, you can change the default Opera zoom to remedy the
microscopicity problem:

Therefore the fact that current Opera versions for example want to

 Anyway, why does this wiki page tell you to enter

 Some future zen compilation of sudo may support infinite nesting of
 levels of protectedness, so that you have to really REALLY mean it to
 say sudo sudo sudo 'make me a sandwich'

I had Zen Buddhist priest training, and I have publicly taken a vow
never to write anything entitled Zen and the Art of Computer
Programming. Stan Kelly-Bootle thought that vow worth recording in The
Computer Contradictionary.

So don't start any Zen threads here unless you know enough to mean it. ^_^

Re: [Server-devel] XS 0.5.1-dev03 with ejabberd goodness, kernel bling, Access Point workingness... looking for xmas testers

2009-01-02 Thread Martin Langhoff
2008/12/30 David Leeming leem...@pipolfastaem.gov.sb:
 -  Installed 0.5 Nov 19th download on Toshiba notebook computer with
 black box prototype AA (USB)
...

 -  yum --enablerepo=olpcxs-testing update
 -  restart

Just to make double, triple-sure... can you tell us what the ouput of ...?

   rpm -qa ejabberd-xs

 -  One one of 4 XOs, log onto ejabberd web admin and set up shared
 roster Online

 -  restart

 -  start all four XOs and register, then restart

the restart here is just of the XOs, right?

 At this stage I cannot see any other XO...

Damn, this is so strange. Something else must be getting in the way here.

 Log attached

Thanks! I've reviewed the logs. They look very normal to me.

I'm a bit lost here. Something is subtly wrong somewhere. Either in
the procedure you're following or in the software. We need to find out
what it is...

cheers,

[Server-devel] File Sharing on XS - (was:XS 0.5.1-dev03 with...)

2009-01-02 Thread Martin Langhoff

 I want to do a new install but can you let me know if I can install Samba
 and how to set up access to a shared folder on a Windows PC on the LAN as I
 have a large content collection and it takes ages to copy it all again by
 flash drive. Or maybe there is a better way to do it.

 I was curious about that, too, so I looked into other alternatives as Samba
 can sometimes be a pain to configure.  It's also yet another service to run
 on the XS.

 I found an sshfs utility for Windows called Dokan.  And it's free for
 non-commercial purposes!  This might make more sense than fooling with
 Samba, especially if you only have one Windows machine to deal with.

Good tip about sshfs - I didn't know there was a workable Windows
implementation. Another route could be the Fuse-for-windows
implementation I frequently hear about.

But we have another path we an follow :-)

There are some patches for Moodle 1.9, written by me (and included in
2.0) that add support for WebDAV.

So this is a separate thread on this matter (easy file sharing for
XS?). So far

 - Samba
   - fastest, most mature
   - hard to configure clients (authentication issues, etc)
   - assumes reliable connectivity - clients lock up briefly if
connection vanishes
   - does not integrate well with moodle
   - not NAT-friendly

 - ssshfs
   - slow
   - well supprted on linux,  Dokan (?) for Win
   - authentication issues
   - does not integrate well with moodle
   - NAT friendly

 - WebDAV
   - a bit slow
   - well integrated with Moodle (including authentication)
   - we still have to do some minor auth work as we don't use
username/pass scheme which WebDAV implementations assume
  - NAT friendly
  - patches for moodle already exist, well tested and written by... me!

cheers,
