Computer power; was Re (3): Logjam vulnerability and epiphany.

[peter]

My biggest Internet usage is still email. 

For the majority of my Web interests, Dillo is preferable to Epiphany.
Opens almost any Wikipedia page in a few ms (blink).  

JavaScript is the biggest block to Dillo doing electronic banking. Is 
execution of code from a remote server on your machine, with access to 
your accounts, really a good idea?

The camera is dispensible.  Decent UVC cameras are available from salvage 
shops for 10 dollars or less.  

Minimal, at least, operation of DCON and power management are necessary.
Elaboration is helpful; not essential.

Even the XO-1 has ample go power for ETH Oberon and A2.  Hypothetically 
of course but not far from reality.

Endless hardware upgrading keeps Google, Microsoft, etc. and etc. in 
business.  Necessity to human needs is arguable.  Too many people I 
know would have trouble explaining what the Web is and have forgotten 
that email worked as well on a 486 in 1995 as it does now on an 
expensive contemporary machine.  I doubt that shiney new computers 
will help these people understand more.

The world already has far more than enough e-waste.

Re: Logjam vulnerability and epiphany.

[James Cameron]

Thanks for the question.

We have no plans to declare end-of-life or end-of-support for the older XO's.

As far as I can tell, in making such a declaration there would be no
net benefit, and some additional cost.

There are very few of the older XO's in use.

Re: Logjam vulnerability and epiphany.

[Samuel Greenfeld]

While it is possible to partially fix the LogJam vulnerability, are there
plans to declare end-of-life or end-of-support for the older XO's?

A few years ago, we talked about ending support in 2020 when other Linux
distributions would stop distributing x86 processor builds.

And OLPC is not like the OpenWRT project, where developers have kept things
up-to-date even for legacy hardware.

Incidentally, Dillo can retrieve and render pages from Wikimedia

Dillo doesn't support JavaScript.  Nevertheless Dillo presents text

Glitzy multimedia doesn't work automatically.  Nevertheless a 
multimedia file is easily retrieved; then played by software such as 
the Movie Player (formerly known as Totem).

Re: Logjam vulnerability and epiphany.

[James Cameron]

Yes, wikimedia servers will be unreachable.  That is their decision.

Many other servers already do not permit connection, and this varies by 
geography of IP address, based on local laws or a server owner's assessment of 
market value.

We have no plans to upgrade for XO-1.5.

Is not a problem on NL3 or ED20 models with OLPC OS 20.04.

Years ago, changed the internal SDHC to 8 GB.  About a year ago, 
replaced the battery pack with a new one sent from Australia by Terry 
Gillett; thx Terry.  Otherwise all original.  Good reliable little machine; 
on a par with the VW Beetle.

The test was done in the evening, temperature 20-25 C.  Will try 
again and check the thermometer.

Will do.  I'm contemplating to find a 1.75 on eBay.  

Possibly a new infinity.  Not clear whether the proposed modularity of the 
Infinity was implemented in production.  Also not clear whether the case 
is elastic polymer or hard polymer.

Re: Hardware test in 1.5 reports temperature rise of 9 or 10 C.

[James Cameron]

Thanks, that's interesting.  This serial number was produced in late
January 2011, about 9.5 years ago.  I would have expected it to fail
much sooner.  It has lasted well.

The temperature rise test was only characterised for manufacturing and
some accelerated aging tests.  The test has no statistical meaning now.
The test should be done at an ambient temperature of 21°C to avoid
false positives.

In my experience the most likely causes of the test failure are;

- high ambient temperature due to season,

- high internal temperature due to repeated testing,

- missing or loose screws holding down the heat spreader,

- dents in heat spreader due to impact,

- age hardening of the silicone plastic thermal pad between the heat
  spreader and the CPU.

I suggest ignoring the problem for now, as servicing may cause damage
beyond economic repair.  In particular for the CPU interposer board
solder balls, which are under significant stress.

Re: XO1.75

[James Cameron]

Based on memory, 00 means fault in RAM.  Replace RAM.  Could also be 
electrostatic damage to CPU or RAM.  Could also be age degradation of silicon 
chips.

To find the real meaning of 00 takes reading the C code of the CForth startup 
payload, which is loaded from SPI Flash.

There is no involvement of eMMC or SD card slots.

Thank you Peter,
But there is no way to get to the Forth PROM or get hardware diagnostics or 
anything on the screen other that the 2 big zeros mentioned above.
Looks like there is no firmware in this machine! 
As if the eMMC is wiped clean or missing.

This XO has a serial port connection attached
Any diagnostics through this?

Thanks

Re: Announcing OLPC OS 13.2.11

[Carrol Riddle]

The release of 13.2.11 is particularly apropos at this time, as 
Internet-in-a-Box (IIAB) content has just become accessible to XO laptops here. 
 Thanks James.

The OER2GO (RACHEL) content packages on IIAB become available to the XO laptop 
by slightly modifying a "copy" of the index.html(f) of each package.  XO 
Browse, web browser, can call this copy with 
http://box.lan/modules/en-ck12/index_xo.html   (e.g., ck12 package), which is 
compatible with Browse.

This is a long path for routine use, but it is needed only the first time since 
the XO creates an entry in its Journal.  Clicking on the entry (renamed to 
package name) would start Browse with the path. The "box" feature of the 
Journal allows grouping of these entries into menus of applications, each of 
which can be started with a click. An example menu might consist of: 
kindergarten, elementary, high school.  A list of index_xo.html(f)'s for 
various packages is being collected.

This does not work for ZIM files, but there may be a path forward for this.  A 
similarly modified index (extracted from zim file) would be used.

The package xy utilites for zim files has functions similar to tar archiving 
(wikipedia), which allows extracting a single file.   IF an xy tool allowed 
extraction of file within a "href line" in an index.html file, then the indexed 
contents of the index file might be display for the XO, as with the OER2GO 
example.

Can anyone provide an example of such ?

Re: XO as wireless remote terminal for Internet-in-a-box on Raspberry Pi Zero W

[James Cameron]

Best ask Internet-in-a-Box project about minimum browser requirements;
as far as I know they don't participate here on devel@ or maintain
IIAB for use with XOs.

Re: XO as wireless remote terminal for Internet-in-a-box on Raspberry Pi Zero W

[Carrol Riddle]

sudo apt install dillo   works. (did first removed files from download of 
tarball method)
Website http://wiki.laptop.org rendering is usable. 
Internet-in-a-Box home page is largely not usable.  Presumably, this is due to 
use of Javascript pages.
Will try other lite browsers which claim to handle javascript.

James,
Thanks for intro to field of "lite" browsers -- different from tried links2.
Not successful with Dillo yet. Make for fltk, a prerequisite, fails with errors 
(configure errors ?).
Will also look at others.

Re: XO as wireless remote terminal for Internet-in-a-box on Raspberry Pi Zero W

Most web content demands large browser like Chromium or Firefox.

But where the web content is your own, or under your control, then a
simplified web browser like Dillo may be helpful.

Re: XO's cannot use mirror repo's in YUM update or install

[Carrol Riddle]

Correction: baseurl must begin with "download" instead of "dl" for this case.
Rpmfusion must be installed before exfat.

Re: XO's cannot use mirror repo's in YUM update or install

[James Cameron]

Thanks for the problem report and workaround.

The cause is an SSLv3 Handshake Failure, apparently a result of
tightened security configuration at fedoraproject.org which is no
longer compatible with Fedora 18.

Unfortunately yum does not report the actual problem.

Here's how to catch proof;

1.  use tcpdump to capture network packets and then wireshark to
analyse,

2.  look for the "Alert (Level: Fatal, Description: Handshake
Failure)",

3.  look for the immediately preceeding SSLv3 Client Hello message,

4.  note the Cipher Suites list contains some that are no longer
acceptable.

Your workaround is fine.  It is similar to the one I used for XO-1.75
and XO-4 in 13.2.8;
https://github.com/quozl/olpc-os-builder/commit/f2cb3908aff0cc7bc3ba7937a93b0337140dd81e

Another workaround is to change from https to http in the mirrorlist
entries.

sudo sed -i 's/mirrorlist=https/mirrorlist=http/g' /etc/yum.repos.d/*.repo

However, while this is faster, it also lowers the overall security
because it makes a man in the middle attack easier.

Best way to image a set of laptops with rpmfusion packages is to build
an image using olpc-os-builder.  I've got notes on how to do that.

Re: XO's cannot use mirror repo's in YUM update or install

[Carrol Riddle]

Have been able to Yum install exfat files on my XO-1, but everywhere had to 
block mirrorline and use baseurl. 

Still do not know why mirrors do not work.

The baseurl for fedora.repo is 
http://dl.fedoraproject.org/pub/archive/fedora/linux/$releasever/Everything/$basearch/os/

The baseurl for rpmfusion is 
http://archive.rpmfusion.org/free-archive/fedora/releases/$releasever/Everything/$basearch/os/

dl, download and archive all seem to work as first term in fedora path.

Modified the *-update.repo files similarly (but not same).

I had been using http://wiki.laptop.org/go/Gstreamer  method of installing 
rpmfusion,
but simpler and newer is:
wget -c download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm
and rpm  -i rpmfusion-free-release-18.noarch.rpm

Removed extraneous rpmfusion  repos from /etc/yum.repos.d/

This effort was to allow installing Internet-in-a-Box on a larger SD for 
Raspberry Pi Zero W using only XO and the Zero.
Two external ports are needed and had previously used Pi 4 to prepare SD.
The single USB port on Zero is used for the connection to an XO using 
X11Forwarding for display, keyboard and shared WiFi (secondary to Zero W 
on-board WiFi or as primary for simple Zero).

Still looking for cause of YUM Mirrors failure.

Re: XO's cannot use mirror repo's in YUM update or install

[Chris Marshall]

I had the same problem last week.  I did determine that the Fedora packages
had been archived but I could not figure out how to get yum to work.  Maybe
it is a different type of repository?  At any rate, I was unable to get yum
to work.

I'm guessing you might need to update for content that has been
archived, I thought the mirror manager dealt with redirects
automatically there but I don't know exactly.

Thanks to people like Jerry Vonau & George Hunt who've made an intensive QA
effort happen in recent weeks, so that IIAB 7.0's Release Candidate will be
available very shortly in coming days!

A self-hosted, all-in-one radio station platform called AzuraCast[*] is
even now available as part of Internet-in-a-Box — to schedule podcasts,
music, and even do live streaming of audio content:

https://github.com/iiab/iiab/wiki/IIAB-7.0-Release-Notes


[*] fyi AzuraCast requires Ubuntu 18.04 or Debian 10 for now.  It might run
on Raspberry Pi later this year!

Hmmm, but it also turns on the DT flattening which is mutually
exclusive with ATAGs (because r2 points to either of them). I think the
legacy kernel wouldn't even be able to get any kernel command line
arguments (including root=) or memory size. I though the machine ID is
also different for BSP-based kernel than for the FDT-based.

That said, I haven't actually tested whether that is the case. If it
somehow works, but I can't see how (kernel using built-in arguments and
ignoring machine id? no idea).

Sounds about right. In general I think it's the *-arm-linux-gnu cross-
toolchain packages + the RPM's BuildRequires.

This second image removes the ablity to boot the legacy OLPC OS kernel,

By the way there's this patch we could use if we needed stable device
names:

https://lore.kernel.org/lkml/20190416133930.1819-1-lkund...@v3.sk/

But as the OLPC OS' initrd already relies on incorrect numbering
(different from what OFW and presumably marvell uses) and the dtcompat
translates it to something yet more incorrect, this wouldn't really be
useful for compatibility. So if nobody picks up the patch, there's
probably not much point in pushing it forward.

Thanks, that's fantastic.  I've mostly reproduced your work, and have

Oops, I should have read all this way before acting.  I got caught up
in code review.  Sorry.  I'll do another test using your binaries.

By the way, there's an interesting symptom on WiFi, a variable latency
on inbound ssh, also shows up as a latency staircase effect in
outbound "ping -n -i 0.200".

Also, power is not turned off on system halt.  I remember fixing that
once, so no biggie.

Bit 12 is a clock select,

bits 7:6 are clock source multiplexor,

when bit 12 is 0, bits 6:7 have meaning; 0x0 selects PLL1 divided by
two, 0x1 is PLL1 divided by three, 0x2 is PLL2, 0x3 is PLL2 divided by
three.

when bit 12 is 1, bits 6:7 have meaning; 0x0 selects PLL2 divided by
four, 0x1 USB PLL, remainder reserved.

Other bits in the register let me put a story to this;

1.  the module is powered up (3<<9), and the peripheral (1<<3) and AXI
bus clocks (1<<2) are turned on, then there is a udelay(150),

2.  isolation is disabled (1<<8), and then there is a udelay(1),

3.  reset is released on the AXI2MC interface (1<<15), reset is
released on the GC controller (1<<0), and then there is a udelay(100),

4   reset is released on the GPU AXI (1<<1), and then there is a
udelay(100).

Don't know why the delays are needed, sorry.

So, over the last week or so, I spent some effort making this work with
the OLPC RPM build tooling. Here's what I came up with:

http://v3.sk/~lkundrak/olpc/green_ears.jpeg

The kernel:

  git pull https://github.com/hackerspace/olpc-xo175-linux/ olpc-5.0

Based on vanilla v5.0.8, a few parts taken from olpc-4.8, olpc-3.0-arm, 
along with my defconfig and a couple of changes to support cross-build
on Fedora 30. I've not tested native builds, I didn't dare to run it on
the XO.

Firmware:

  git pull https://github.com/lkundrak/openfirmware/ lr/olpc-xo175-3

A couple more small fixups here and there since lr/olpc-xo175-2. The
most notable fix is for a regression that caused the RTC to be cleared
on each boot.

  git pull https://github.com/lkundrak/dracut-modules-olpc/ master

There's a fix for assumptions about the mmc controller numbering. Also,
to boot a FDT-based kernel the initramfs needs to avoid triggering the
compat boot path (that lies about bootpath and disables the DT
flattening).

  git pull https://github.com/lkundrak/olpc-utils/ v5.0
  git pull https://github.com/lkundrak/olpc-utils/ master

Fixes the X11 video.

The patched packages are here: http://v3.sk/~lkundrak/olpc/
The dracut-modules-olpc package needs to be installed prior to the
kernel.

Or $35 RPi4 in 2020 which might even raise your hard-disk transfer rate
well above the current USB2 theoretical max of 60 MBytes/sec -- just don't
count on SATA or NMVe or M.2 (:

My point earlier was simply that well-meaning people who are unfamiliar
with the developing world (quite the opposite of Tony Anderson) should
avoid wasting their money buying $68 400GB
 and $130 512GB
 microSD cards for Raspberry Pi...the
reasons are not always obvious in the rich world:

   1. Tiny $~100 items (a microSD card is smaller than a penny) can
   "silently disappear" in classrooms/countries where that represents a
   month's salary.  Recriminations across the school become very serious in
   cases of theft, sometimes resulting in cancellation of their computer
   program.  Yep "thoughtless generosity" can frequently backfire.
   2. Even the temptation of theft can create dangerous social disruption
   in impoverished schools/countries especially -- whereas a wealthy volunteer
   typically won't give a thought to $100, not realizing this is equivalent to
   leaving $10,000 in cash completely unprotected in a classroom in a rich
   part of the world -- e.g. in places like NY City where teachers salaries of
   $100,000 to $120,000/year exist (and are no longer uncommon).
   3. A USB hard disk can be a much better use of funds than a microSD card
   among groups that want a "full library experience" (as you point out).
   Particularly if they have people who are experienced/intelligent enough
   (like yourself) to fill those TB disks with high-quality and
   locally-relevant local-language materials.  Conversely I've met many
   well-meaning NGO's and govts who do not have a clue how to fill even a
   fraction of their 1TB disks with pedagogically relevant/useful/legal OER's
   (open educational resources) *so our road remains long :)*

Re: [Server-devel] Booting from a big USB stick

[Tony Anderson]

Hi, Adam

As you know this is an area where we agree to disagree. Currently the 
schoolserver's valid, useful content exceeds 500GB. I really do not want 
to get into the game of deciding what is worthwhile and what is not. It 
is clear that the planned expansion of OSM will require increased 
capacity. If local content is seriously supported, the amount will 
increase even further. At one time OLPC estimated storage of the Journal 
would take 2GB per XO. A typical Rwanda school has 200 XOs potentially 
requiring 400GB of additional space.


My dream is an RPi3 based schoolserver with a 1TB (or 2TB) external 
hard-drive at under $150 (about 1/3 of NUC-based server).

Re: [Server-devel] Booting from a big USB stick

[Adam Holt]

Thanks Tony.

Another option is to buy a $19.99 128MB 100 MByte/sec microSD @
https://amazon.com/dp/B06XWZWYVP

Or a $39.99 256GB 100 MByte/sec microSD @ https://amazon.com/dp/B072HRDM55

The 400GB, 512GB and 1GB cards are completely excessive & irrelevant for

important cause in which case do let us know...we will happily put your

Re: [Server-devel] Booting from a big USB stick

[Tony Anderson]

Hi, Gerhard

The trick is to separate the server software from the content. Install 
the basic IIAB on a smaller SD card (e.g. 16GB). Then mount the 128GB 
usb drive (mount /dev/sdb1 /media/usb0 for example). IIAB expects the 
content to be in /library. This should be possible by a symbolic link 
such as /media/usb0/XC /library. XC is a folder containing the content 
whereas usb0 is a partition. The original installed content in /library 
on the sd card needs to be copied to the XC folder on the USB stick 
before the symbolic link is made. In principle, Ansible should recognize 
the /library (XC folder) and operate as expected.


Tim Moody has an img of the basic installation which should be perfect 
to set up the SD card (simple dd). I am looking forward to trying that. 
I am hoping that the img sets the 'box' (hotspot). This should mean 
everything can be done headless via ssh.


As always, it will be an adventure.

Tony

ok
then i wanted to let work this magic sentence

That seems to be German for:

Can not find a valid file system superblock.


What exact OS are you running?

Internet-in-a-Box strongly recommends Raspbian -- any one of the 3 from
this page:
https://www.raspberrypi.org/downloads/raspbian/


PS click "installation guide" near the very top of that page if you're not
used to burning/flashing images using Etcher, Win32 Disk Images or "dd".

The equivalent 2 commands (can be run as part of Internet-in-a-Box/IIAB 7.0
master branch pre-releases) are:

   /usr/bin/iiab-hotspot-off
   /usr/bin/iiab-hotspot-on

Sometimes a reboot is also necessary, after running either of the above.

They've been improved over the last month, so please do _not_ rely on these
as part of older IIAB 6.7 installations.

These are simple bash scripts, whose internals can be seen here:

https://github.com/iiab/iiab/blob/master/roles/network/templates/network/iiab-hotspot-off
https://github.com/iiab/iiab/blob/master/roles/network/templates/network/iiab-hotspot-on

Finally, here's a command that helps you monitor whether running these was
successful:

   brctl show

Re: [Server-devel] [UKids] Where I download KA Lite zip file in Spanish

[Adam Holt]

Steve,

There's extensive documentation on KA Lite tips & tricks for
Internet-in-a-Box at http://FAQ.IIAB.IO #32

("KA Lite Administration: What tips & tricks exist?")

Read those 30-or-so lines from top to bottom, as so many others have fallen
in these kinds of KA Lite content installation & configuration traps over
the years, that you can save yourself a *Lot* of hassle by avoiding their
mistakes (:

Sorry.  Configuring and building kernels is for me a rare thing to do,
and whenever I try I'm usually interrupted by something more urgent,
as I've quite a few other things I've got to do.  I'm still a newbie
at it because I can't dedicate the time.

http://dev.laptop.org/git/olpc-kernel/commit/?h=olpc-4.8=4731695ff517ccb145e60d68acd2f7f15eb4ab6b
is an example patch which, in addition to a few irrelevant changes,
adds our OLPC RPM build process;

- our defconfig,

- a spec file for rpmbuild,

- a build script,

- an openfirmware boot script.

Some of this may have bit-rotted.

Figured out what's wrong. There's actually three drivers competing for
mrvl,pxa-uart, one of them deprecated the two other broken. This should
eventually be somehow disambiguated, but for now I just sent in the

Makes sense. I think the self-test still works and none of the existing
funcitionality was broken deliberately.

[...]

I've given the thing some more testing and fixed up some of the
commits. I've also added an ext2fs fix that would be corrupting the
file systems with incompatible flags (the stock Fedora image), despite
being able to read it okay:

  git pull https://github.com/lkundrak/openfirmware lr/olpc-xo175-2

(diff it against lr/olpc-xo175-1 to see what changed)

Ah, okay. It might then just be that you don't have the olpc_apsp
module in the initrd. That might be the case especially with an older
dracut version and when running a kernel that has the APSP driver
built-in.

Some other drivers might be missing too. Here's one that's known to
have the necessary modules (generated on my f29 running a Fedora
kernel):

https://fedorapeople.org/~lkundrak/initramfs-5.0.0-0.rc7.git2.1.fc31.armv7hl.img

If things still don't work afterwards, please share the dmesg.

Yes, it looks reasonable.  Given that the firmware would not need to
run in factory and would only be used with a new kernel, the rest of
the firmware functions won't need to be considered.  I'm not worried
if it breaks the self-test features, for example.

I intend to look into the key mapping at some point, because I've
noticed the keyboard sometimes sends scancodes the kernel doesn't
recognize.

By the way, my unit has has the "olpcm" non-membrane keyboard. I'm
wondering if the scan codes it sends are the same as the membrane one?
Will the key mapping in hwdb need to distinguish between the two? (I
also have a membrane keyboard, so I could actually just check that
myself...)

Yeah, the device names are not stable for some reason. I don't know how
are they determined, I'll need to take a look. Perhaps it's just a
matter of adding the right aliases to the device tree.

Somewhat wierdly, my stripped down monolithic kernel calls the UART2
ttyS2, while the Fedora kernel ends up with ttyS0.

Similar issue with the MMC; the SD card ends up mmcblk1 with one
kernel, mmcblk0 with another.

The actual boot parameters I am testing with are in the lower half of
my boot script (it's somewhat messy, copied it directly from my /boot
without an attempt to tidy it up):

Which exact kernel are you using? Keyboard is not expected to work
before rc6.

Also, which config? Mine is basically this:

Ah, cool. Good to know there's a reasonable recovery option. Hope my
chip is 3.3V, because I dropped the programmer that could do 1.8V on
the floor and it seems it needs repairs :) 3.3V one could be programmed
with a Rasbperry Pi, and I even have some spare 3.3V chips if I fuck up
majorly.

But for now I just stay off overwriting cforth because I don't even

Re: OpenFirmware and Linux v5.0 on XO-1.75

[James Cameron]

Thanks, very good progress.  Here's what I've done;

- reviewed the aggregate change from master branch, and each commit,

- built the firmware on my xo-4 build server, flashed an xo-1.75 c2
  sku200x2; it boots fine the old kernel from arm-3.0-wip branch, with
  some unimportant problems like keymapping,

- on the fedora 18 root filesystem, installed the 5.0.0
  kernel{-core,-modules,} with --nodeps and --force,

- adjusted boot/ so that olpc.fth runs the 5.0.0 kernel,

- booted it a few times trying to fix the missing root filesystem;
  more work needed, the device name may have changed and i've not
  found a way to find what it is, or it isn't being detected; serial

My mind has bitrotted.

On your interest in building on x86_64, suggestions;

- there are six 0.1" pitch pads on the back of the PCB which expose
  the SPI Flash chip pins, so you can hook a programmer to them, but
  check the voltage levels; some units used 1.8V chips, most used
  3.3V.

- build a composite image by hand using the cforth you know already
  works, and the openfirmware built on x86_64,

- use binary comparison of the .rom file to make sure the cforth
  section hasn't changed much; if it hasn't, probably good to go, but
  if it has, no idea.

Re: [UKids] [Announcement] Sugarizer v1.1 is available for your device

[Lionel Laské]

Hi Simon,

Thanks for your interest on Sugarizer.
If you're running Sugarizer Server into Docker, the file to update is
env/docker.ini (not env/sugarizer.ini).
You could see (and eventually change) this settings here:
https://github.com/llaske/sugarizer-server/blob/master/docker/Dockerfile-server.tpl#L3

Best regards.

  Lionel.

On an XO-4 running OLPC OS 13.2.10, the latest version of Python,
which is 3.7.2, does build like this;

yum install -y gcc make zlib-devel
./configure
make
make install

Here's the interactive interpreter running;

Python 3.7.2 (default, Jan  3 2019, 08:52:48) 
[GCC 4.7.2 20121109 (Red Hat 4.7.2-8)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

However, there are other optional dependencies that should be
installed first, so that the build has all the features possible.  The
Fedora 18 source package for python3 has a good starting point for
dependencies.

Had a look, saw nothing obviously wrong.  Am a bit worried about the
amount of dictionary space remaining; you could reduce that worry by
removing those constants and adding the names as comments later.

Also you might check for data or control stack excursions; check
balance of the stacks across the fload.

Yes, figuring out is non-trivial.  We rarely made significant device
tree changes at this stage, we try to bring them into the source.
There is simultaneous activity going on (keyboard, USB), and it's not
as multi-tasking as other environments.  Use ftrace after the "Data
Abort" to see if the saved exception stack can tell you anything
interesting?

CLARIF: Internet-in-a-Box 6.7/master is a rolling release, rather than a
fixed/finalized version.

It's heavily QA'd on a daily basis thanks to a number of *quite incredible
volunteer contributors*, and as a result is already in use in a few
production environments.

FYI it is a step up from Internet-in-a-Box 6.6 released on Sept 12:

Just to clarify, the idea is to make available suitable quantities of the

whole lot to one destination.

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[Carrol Riddle]

All,

The solution is trivial and deceptively so.

With the Pi Zero DISCONNECTED, use Gnome Desktop to edit / add connection to 
create a connection method with type Ethernet. Leave the mac address fields 
blank. Pull down tab IPv4 and select "share with other computers " and save / 
power off. Connect Zero and power on XO.  The Pi Zero connection is 
automatically  establish and persists through subsequent boots.  Note that the 
mac fields remain blank.

No special configuration for XO is needed. The Raspberry Pi Zero setup is as in 
the first post. Basic setup -- 'host_addr' and 'dev_addr' are not needed in 
cmdline.txt .

Area's that I might monitor are other connection methods marked to "try to 
connect on boot" and any changes to mac addresses and "no auto default" in 
/etc/NetworkManager.conf  .

Prior practice was to power on XO with Zero connected and the connection method 
was automatically created with a random mac. If the mac field was changed, a 
"connection error" would occur.

With an Activity to run a script, simple access to the Raspian Desktop should 
be possible from Sugar. 

A shout-out to Tony Anderson who may have such an Activity.

This should close my request for help with resources.

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[James Cameron]

That's great.  I've a Raspberry Pi Zero and XO-1 that I can put
together.  Might even be room inside or etch some of the back
plastic.

All:

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[Carrol Riddle]

James,

Thank you for answering request for identifying resources and beyond for the
specific testing.
I had been using udevadm, but not monitor. Your point about possible racing is
supported by observations noted in previous post. The pattern of lengthening 
"no-auto-default" line in NetworkManager.conf may also show varying boot paths.

A topic of interest is web discussions of failures of 
NetworkManager-wait-online.service as typified by:

purschel.eu/linux/centos-7-networkmanager-wait-online-service-failed/

MetworkManager-wait-online.service functions on activation of interface and 
does not wait for interface to obtain IP address and then come online.

NetworkManager-wait-online.service is enabled on XO (systemctl is-name). The 
parts in the above example fix (nohup,nm-online) are on the XO.  Do not know 
ExecStart part. systemd-networkd-wait-online.service used by other examples is 
not on XO  .  Application machanger has been used in other examples.

My more immediate concern is bringing up the small starter network with 
provided Village Telco routers for these XO's in a dense inner city 
neighborhood.

Will have to come back to this topic later. Appreciate the kick-starter.

N. C. Riddle

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[James Cameron]

In my tests just now on OLPC OS 13.2.9 and an XO-4, my USB ethernet
adapters always come back after reconnection or reboot with the same
MAC address.  With or without Network Manager running.  So that
suggests that for adapters with a physical address ROM or
preprogrammed flash, they will appear predictable.

My tests above were not with Raspberry Pi Zero.  So I now turn to
testing with one;

1.  the MAC addresses change on each boot of the Zero, and are
unpredictable,

2.  the MAC address shown on each end is different; comparing usb0 on
the XO vs usb0 on the Zero,

3.  turning off Network Manager has no effect; therefore this is not a
Network Manager behaviour as you surmised,

I've also tested with kernel v4.15 on an OLPC NL3, and the same
unpredictable MAC address behaviour occurs.

Perhaps it is udev?  Using udevadm --monitor --property, shows
several events from the kernel, and the first one to mention the
MAC address eventually used is this one;

UDEV  [861.284453] add

So the MAC address originates from the kernel or systemd, not Network
Manager.

As there is a udev event, it should be possible to write a udev rule
to change the MAC address when this or one of the later events
arrives.

However, perhaps we can see if this MAC address comes from the kernel
or systemd; the event above references
/lib/systemd/network/99-default.link which says'

[Link]
NamePolicy=kernel database onboard slot path
MACAddressPolicy=persistent

Now, setting MACAddressPolicy to none has no effect, which
suggests the random address is coming from the kernel.

My guess is that the reason why your udev rpi script fails is that it
is triggered on more than one udev event, or races with other things
for access to the device.  Add more logging and debugging to it.

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[Carrol Riddle]

The difficulty is that a new connection is started on each boot and starts as 
"automatic" IPv4 instead of the desired "share with other computers" This 
results from a randomized MAC address, which appears to be controlled by 
Network Manager. If the MAC address persists on next boot,
then the connection file will persist.

The MAC address in the cmdline.txt on Zero is vestige of efforts. It was left 
since I suspect it will be part of the solution. Retested without and it makes 
no difference when no other changes are made (i.e., only with essentials in 
cmdline.txt). I have tried static IP on Zero via adding ip=192.168.1.2 to 
cmdline.txt or in dhcpcd.config and udev rule on XO for ip=198.168.1.1  .  
Uncertain if udev rule needs additional specification (parent ATTRS ?).

Reasoned that host_addr was telling Zero where to find existing MAC on XO and 
udev rule then tried with hw to assure it was there.  Have tried adding 
mac-cloned-address to NetworkManager.conf 

NetworkManager randomization of MAC addresses is widely discussed in search 
results and variety of solutions proposed.  I have had periods where MAC was 
persistent, but only have it fail a few hours later (just powered off). One 
case of oddity was the persistence on every other boot, if the intervening boot 
was without Zero attached.  However, my work with wired links to routers 
(TP-Link MR3020 and Village Telco MP20) shows persistence in boot of router.  

A competent programmer might just modify the started connection file (using 
awk, grep, sed ?) and restart NetworkManager.   :)  .  I tried replacing (cp) 
with model files, but that has problems (date stamp).   
/etc/NetworkManger/connections 

What I see points me to NetworkManager,

Re: Disable (?) NM random mac for shared XO wifi - USB0 / Chrome/ Pi Zero

[James Cameron]

Interesting.

But why do you need to give a MAC address on cmdline.txt on the RPi
and in the XO udev script?  g_ether should assign an address, and
cdc_ether should receive it from USB descriptors.

Re: [Server-devel] Internet-in-a-Box 6.5 Released!

[Adam Holt]

FYI an emergency hotfix was added to IIAB 6.5 (and to our master branch) in
the last hour, thereby upgrading kiwix-tools from 0.5.0 to 2018-05-24, to
remediate Full-Text Searching within ZIM files that contain an internal
index.

If you'd already installed IIAB 6.5, it is strongly suggested that you
apply the patch (PR #818 ) as
follows:

   cd /opt/iiab/iiab
   git pull
   mv /opt/iiab/kiwix/kiwix-serve /tmp
   ./runrole kiwix ...or "./iiab-install --reinstall"

Thanks All!

LTS...and is now part of Internet-in-a-Box 6.5!

Thanks all for kicking the tires, before our own big IIAB 6.5 release

This confirms an Internet/hosting/mirroring failure of some kind, as I just
reconfirmed the exact same command "*apt-key adv
--keyserver keyserver.ubuntu.com  --recv-keys
93C4A3FD7BB9C367*" works for me in Raspbian Lite.

*Clarif: I deleted my prior key to be 100% sure, using "apt-key del

Consider another ISP using your phone's data plan or a friend's home if
possible?

(Or install Ansible 2.5.2 in some other way if you choose!)

Re: [Server-devel] Error When installing IIAB 6.5 on RPI

[Adam Holt]

General Aside: you will always make your life easier by removing prior
versions of Ansible, if a prior version of Ansible exists on the computer
where you will be installing IIAB.

As documented in the long-term installation instructions, under Item 5.
here:

https://github.com/iiab/iiab/wiki/IIAB-Installation#do-everything-from-scratch


*In short: verify you have Ansible 2.5.2+ installed (use "ansible
--version") before you begin the meat of the installation...that is if the
1-line install scripts at http://download.iiab.io/6.5
 don't take care of everything!*

This error is arising as /opt/iiab/iiab/scripts/ansible tries to install
Ansible 2.5.2

What exact script are you running from http://download.iiab.io/6.5 ?

What exact hardware and Internet uplink (Ethernet? WiFi?) are you using?

Please paste in the results of running these 3 commands:


apt update; apt -a list ansible dirmngr

cat /etc/apt/sources.list.d/iiab-ansible.list

Re: [Server-devel] Server-devel Digest, Vol 129, Issue 9

[Tony Anderson]

What is the impact of this approach on internet dependence? The main 
problem I have is to create an offline
service with content. This has led to the creation of 'bernie', a copy 
of the schoolserver on an external 1TB drive.
There are, of course, many problems with dependencies. I view resolving 
these as the task in making bernie. I am
not sure what is meant about cross contamination. There are many 
duploicates in the current bernie - for example, Rachel
includes a sizable number of items from the Gutenberg project as does 
OLE Nepal's Pustakalaya. There is enough hard drive

space so this duplication is no problem.

Tony

Greetings!
I haven't written to this list in a while.

I am working with some other OLPC-SF members to package and make
available Pathagar using the snaps (http://snapcraft.io platform). We
are currently doing this as part of a two-day hackathon
(http://hackathon.sfsu.edu/challenges/snap-ify-pathagar).

Of course, the work continues past this hackathon, but let's see how
far we can get today. Right now, we are using the NextCloud snap
(https://github.com/nextcloud/nextcloud-snap) as a base example and
adding/removing to it to see if we can put together a snap.

If you haven't used snaps before, try it out the NextCloud snap. On
Ubuntu/Debian, try "sudo snap install nextcloud" Give it a few
minutes, and when installed go to http:// and it should
be there.

Our proposal and approach is to first do this with Pathagar, and then
see if we can do this with all the other services on the school
server. This will give deploymentw a menu approach to adding services
without worrying about dependencies and cross-contamination and such.
It's a little bit more work to architect services that do talk to each
other, but we think that in the end it's a much cleaner solution.

Ideas? Comments?

Please let us know. Andi Gros, Aaron Borden and myself are working on
this currently.

cheers,
Sameer

Which things are truly important depend on the circumstances, and only
the teacher will know.  For instance, without deleting the identity
key the activity collaboration feature will fail in strange ways.

Re: [Server-devel] [UKids] easiest way to automate install of a collection 12+ PDF's onto Sugar on XOs?

[James Cameron]

OLPC OS on the XO is configured for ownership style "one laptop per
child".

If you always want to delete the child's Sugar name, you might either
change login scripts to delete it before starting, or assume a
default.  It simplifies getting started into a class.

e.g. in the OLPC OS 16.04 live build on the NL3, we have this in
/usr/bin/sugar;

gsettings set org.sugarlabs.user nick 'You'
gsettings set org.sugarlabs.user gender ''
gsettings set org.sugarlabs.user birth-timestamp 689659403
gsettings set org.sugarlabs.user group-label 'Adult'
gsettings set org.sugarlabs.user color '#808080,#c0c0c0'
gconftool-2 --set /desktop/sugar/user/color --type string '#808080,#c0c0c0'
gconftool-2 --set /desktop/sugar/user/nick --type string 'You'

Re: sugar-install-bundle fails to behave like Browse when installing .xol bundle

[James Cameron]

Your bundle does not meet the requirements.

I've downloaded it, and sugar-install-bundle says what is wrong;

sugar3.bundle.bundle.MalformedBundleException: All files in the bundle
must be inside a single directory whose name ends with '.activity'

Sure enough, "unzip -l" shows the directory name does not end with
'.activity'.

Re: how to change Sugar's timezone+language after XO deployment

[James Cameron]

Supported method for configuring timezone is the "timezone" option in
the "[base]" section of the OS Builder configuration file.

Traceback you show is not fatal, is irrelevant, but is a bug that
should be fixed.

https://github.com/sugarlabs/sugar/issues/793

You should not use sudo for this command.  Sugar timezone is not a
system-wide configuration setting; it is local to the user.

There are many similar suggestions here:

   http://wiki.laptop.org/go/Imaging/Side_effects

Which of the above are truly important for a teacher to type in at the
beginning of the semester, to clean out Sugar on an XO.

Teachers much prefer something very short like "rm -rf /home/olpc/.sugar"
(unless there's a better way?)


PS Naturally Gnome is not as easy to clean out, if students have left MP3's

'rm -rf /home/olpc/sugar/datastore' is not sufficient to accomplish the
required task (deleting the child's Sugar name).
