Re: [Server-devel] [XSCE] 1TB microSD

[Sameer Verma]

Pricing will come down, like all other cards in the past. I agree that
shipping content will be a big plus.

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] [XSCE] "Raspbian reserves 4% of all disk space"

[Samuel Greenfeld]

The default threshold probably was 5%, and intentional.

This buffer is meant to allow the root user to use & recover the system if
it is nearly full.  So if this file system has any system purpose and is
not purely for the digital library, you probably want the 5% there.

It also allows the filesystem to have some breathing room for
defragmentation as well as not fragmenting files in the first place.

Hm. Way sooner than I expected.

But does it work?

Could mean coovachili works, if the packages are there.


More Detail in the blog post (
https://www.raspberrypi.org/blog/raspbian-stretch/)

Example:

"BETTER HANDLING OF OTHER USERNAMES

The default user account in Raspbian has always been called ‘pi’, and a lot
of the desktop applications assume that this is the current user. This has
been changed for Stretch, so now applications like Raspberry Pi
Configuration no longer assume this to be the case. This means, for
example, that the option to automatically log in as the ‘pi’ user will now
automatically log in with the name of the current user instead.

One other change is how sudo is handled. By default, the ‘pi’ user is set
up with passwordless sudo access. We are no longer assuming this to be the
case, so now desktop applications which require sudo access will prompt for
the password rather than simply failing to work if a user without
passwordless sudo uses them."

Tim does this help Captive Portal implementation?

In any case, this is a major change from the underlying Debian 8.x to
Debian 9.x.

Raspbian "Pixel" appears to have been renamed "WITH DESKTOP" to avoid
confusion.

Raspbian "LITE" retains that name (no X Windows desktop).

Release notes:

2017-08-16:
  * Based on Raspbian Stretch (Debian version 9)
  * Version 60 of Chromium browser included
  * Version 3.0.1 of Sonic Pi included
  * Version 6.1.1 of RealVNC included
  * Version 0.17.4 of NodeRED included
  * Bluetooth audio routed via ALSA rather than Pulseaudio
  * SenseHAT extension added to Scratch 2
  * Various desktop applications modified to prompt for sudo password if needed
  * lxinput control options for mouse speed simplified
  * lxpanel plugins moved into separate packages
  * Wireless firmware for Pi 3 and Pi 0W modified to address Broadpwn exploit
  * Latest kernel and firmware
  * Various small tweaks, bug fixes and theme modifications

 Hi, Adam

 George Hunt's image installs Moodle 1.9.5+ (build 20090910). There was
 a major change in Moodle between 1.9 and 2+. So far as I know, XS has
 always used Moodle 1.9.

 I'll time-stamp it (and scramble your password) so that it's understood

Anish,

5060 for SIP is UDP and TCP, or UDP only?

Re: [Server-devel] [XSCE] Linking (WiFi) SIP telephony and GSM networks

[Anish Mangal]

Another update. Thanks to awesome work by Terry Gillett, I have the same
thing working now just on a tiny AR150 wireless router. This means, among
other things:
1. You can have a WiFi+GSM telephone network just with mesh nodes - no
schoolserver needed.
2. If you have a schoolserver, you can benefit from the additional features
like voice mailbox. However, you need not have the dongle plugged into the
schoolserver anymore. the dongle can be plugged into a mesh node which can
be far away from the schoolserver, and there will be an asterisk trunk
(over WiFi) between that mesh node and the schoolserver. This is useful
since in a village community that doesnt have mobile connectivity, you
would typically place the schoolserver centrally in the village, while the
mesh nodes which are physically, and power-footprint wise tiny, and much
more durable (in terms of temperatures they can handle) can be far away (in
an area where there is GSM connectivity).

We are still doing multiple tests around this to figure out quality of
service, etc., but the PoC works.

Tony,

In answer to your earlier question, George has confirmed XSCE/IIAB 6.2
installs on CentOS 7.3, but does not want to promote this widely until
testing gets substantially more serious.  Testing has progressed further on
Debian 8.6 / 8.7.1 and Raspbian Pixel / Lite to date.  Hopefully you, Anish
and Satellit can pushon CentOS harder this month or soon?

Josh,

Profound thanks for updating/overhauling the above doc (
https://github.com/XSCE/xsce/wiki/XSCE-Platforms) until all OS's are
covered.  Even if our support for the Apple Watch OS has been delayed until
April 1, which I guarantee is used by celebrities who visit refugee camps,
so must not be neglected...but you'll let us know the final verdict as
owner of this document ;-)

Re: [Server-devel] [XSCE] Can I name my server something other than http://BOX.LAN ?

[Tim Moody]

I think the question and answer don't quite line up.  What I name the
server and the alias I give for the browser to find it are not the same
thing.

The host name should be set with either in the admin console or via local
vars as the FAQ says, but the rest deals with aliases.

Are we now at the point of changing the default hostname to box?

I guess I could look at upstream asterisk on the iiab if that'd be of any
use. Its going to be a bit of work, since I had to compile it on my end,
and I had done it on centos7 from which we are moving away from.

Re: [Server-devel] [XSCE] overhauling our FAQ for Internet-in-a-Box/XSCE 6.2 !

[Anish Mangal]

Can someone also confirm whether this release will have the
auto-networking-setup magic sauce? Based on what George said, it wont be
there.

So, for me, this is (a major regression and) mostly a testing release.
Hopefully it gets re-implemented in future releases.

Also, is intel NUC/x86_64 supported "officially" in this release? Is i686
also officially supported (older intel/amd computers)?

Re: [Server-devel] [XSCE] Intel NUC v/s Gigabyte BRIX

[Anish Mangal]

Adam, Tony,

Thanks. The reason for asking this question was pure economics. The BRIX is
$20 cheaper than the NUC from where we can buy it. So if there are no
problems short or long term with the BRIX, would like to purchase that.

The NUC is a nice device, but if we can get similar performance at lower
price, I am all for that.

In terms of battery, if anyone is interested in experimenting dead laptop
battery packs to make battery packs for NUC, please ping me. I have been
experimenting with the same :)

If you want internal WiFi to scale beyond 12 simultaneous connections /
users, this is not possible with Intel NUC (as a result of its soldered-in
WiFi module in recent years, hard-capped at 12 max).

Talk to George Hunt about which WiFi modules he has tested inside the
Gigabyte BRIX to circumvent this limitation...

Re: [Server-devel] [XSCE] xsce on rpi georgehunt's base-6.2

[Tim Moody]

sorry, I may have seemed to imply that ansible needs to be 2.2. I think just 
2.2 or greater. stick with 2.3


see below

Subject: Re: [XSCE] xsce on rpi georgehunt's base-6.2

Is Ansible 2.2 the magical version? I have some notes on my unsuccessful 
attempts to install XSCE. So far, I have not succeeded at installing XSCE on a 
RPI2. (Do note though that imaging my SD card does work on the RPI2.) The 
various Ansible versions are mostly pulled from Github Except where noted.


All of these are RASPBIAN JESSIE LITE and George's Base-6.2 branch (except 
where noted).


  *   Ansible 1.8 Does not work. Roles use new keywords, ansible recognizes 
this and exits.

  *   Ansible 1.9 had a series of problems to what I later think is due to 
newer commands. Also, duplicate keys cause it to halt. (couldnt find duplicate 
keys, but that's what Ansible said). Wasn't taking such detailed notes at that 
time :\.
  *   Ansible 2.3.0 (Installed from Tim's Script.)
 *   fatal: Unable to mark file vars/local_vars.yml
 *   I think this is an attempt to untrack local_vars to permit changes.  
It will only cause a problem if you make changes and later try to git pull
 *   Error occurs and simply continues

  TASK [Gathering Facts] 

  ok: [127.0.0.1]
   [WARNING]: While constructing a mapping from 
/opt/schoolserver/xsce/vars/Debian.yml, line 1,
  column 1, found a duplicate dict key (apache_log_dir). Using last defined 
value only.

 *2.3.0 doesn't care about duplicate keys and gracefully handles by 
using last duplicate key it sees. Previous versions error & stops.

TASK [xsce-admin : Enable ssl]

this would be a new bug as it is the area currently getting worked on

 *   /etc/apache2/sites-enabled/010-xsce.conf line 158 has a type:
*   A bracket breaks the config.
*   Upon fixing and rerunning, the typo resurfaces.
*
*   fixing the target never helps because the next ansible run replaces 
your fix.  need to fix in ansible. hopefully George will do so.

Re: [Server-devel] [XSCE] xsce on centos/rpi3

[James Cameron]

Yes, the Rpi3, clones, and similar devices are encouraging.

We have everything needed for Sugar 0.110 on the Rpi3 within Raspbian
as a desktop option or as applications within the desktop.

I've done tests in my lab as part of testing Sugar for the OLPC
laptops.  My collection of Rpi3 have helped with my recent work on
OLPC OS 16.04.2 on Ubuntu 16.04 and OLPC OS 13.2.8 on Fedora 18.

But my focus is still on OLPC laptops, and so I'm not really in a
position to fully support Rpi3 yet.  The OLPC laptops have the best
Sugar experience, in my biased opinion.

Developers who wish to be involved on a Sugar on Raspbian push should
be talking on sugar-devel@ and taking the lead from Jonas Smedegaard
and Sebastian Silva.  Their work is packaging and integrating, using
resources such as the Debian git repositories, package tracker, bug
tracker, package archive, and mailing lists.  Tip of the iceberg
occasionally shows on sugar-devel@ or Sugar git repositories;
especially noisy last couple of days.

Just FYI a new development is that a growing number of kickass deployments
are asking me for the full Raspian ("Pixel" takes up 3GB more disk "Lite"
version, likewise its zip/download is 1.1GB larger) as it provides an
increasingly well-rounded learning suite for remote teachers/techs/kids to
learn Linux & much more:

   http://downloads.raspberrypi.org/raspbian/release_notes.txt

Aside: currently lacking Sugar regrettably, and not quite as well packaged
for educators as those other Brits @ https://twitter.com/teamkano.
Naturally there are other deployments that do not want these 3GB of
learning/IT tools, as things boot faster without, and traditionalists do
not want visual tools (X Windows).

In essence it took half a decade, but the $35 computer is now unleashing a
lot of field innovation across these 2 categories primarily:
1) "one RPi3 per child" deployments who require modern visual tools on each
RPi3 (and can afford a cheap LCD per child/seat)
2) "one RPi3 server per classroom" deployments (who may or may not be able
to afford an LCD or projector for the teacher)

Of course there are many of both types of learning communities above and
others, who do not always see eye to eye (imagine that, another culture
war, what a surprise ;)  So our Mission is to encourage maximum
cross-fertilization across these most practical scenarios--wherever we can,
despite not-invented-here bubbles of innovation--embracing creative
cross-collaboration / proven best practices as a larger force than
infantile infighting, across an entire planet of fantastically passionate
grassroots implementers~

In many cases Sugarizer-on-XSCE/IIAB can provide a partial answer.  But
Tony Anderson is correct to remind us Sugarizer does not yet provide nearly
as rich an experience as full Sugar.  Meantime all educators cry out for
platform stability that constructionism ironically relies on, so
http://wiki.laptop.org/go/Release_notes/13.2.8 on XO laptops is a big step
forward with Sugar 0.110, thanks to James Cameron!

Not yet.  Most of us are using Raspbian (see Nov 30's

I would love some help with that (upstreaming), but so far there has been
little interest in the PR
https://github.com/XSCE/xsce/pull/804

There needs to be discussion about approach -- how it would affect the xsce
networking. It needs input from people who designed most of the xsce
networking over the past 3 yrs :)

Anish,

How far away do you think we are from implementing a radio button in XSCE's
Admin Console, enabling Captive Portal for all (less literate communities
especially) who need it?

Presumably customizable to http://box or whatever that
location/organization wants?

After much discussion, Meeting Time has been finalized to *Saturday Oct
22nd, 12:30PM NYC Time*.

As it looks like Tim/George/Josh can probably all join 9:30AM PDT from
British Columbia & California, and 11:30AM CDT for Jerry in Manitoba.
Unclear if Avni's able to join while traveling?

In any case that's 10PM Saturday Night in India, so Anish please bring

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Anish Mangal]

For what it's worth, I also got asterisk and freepbx to work (atleast on
centos). It is definitely has more features than kamailio.. and allows for
stuff like voicemail, which can be especially useful in environments with
flakey connectivity. :-)

It might take a bit of time to package as I will be travelling soon, but it
is promising that it is working. :)

If SIP is using a server signaling messages always pass through the

the server. In IAX, signaling and data must pass always through IAX

This increases the bandwidth need by the IAX servers when there are

This is a big drawback of IAX it seems, especially in a mesh setup, 
where in
many cases, the available bandwidth between clients may be higher via 
direct
node routes compared with the bandwidth via the server route. It seems 
SIP

will utilize the network more efficiently in a mesh topology.

Yesterday we were testing this on the server, and two nodes with three

and virtually no bandwidth was being used on the server. :)

It might be worth talking to the Village Telco folks and see if you can
do something that'll work with their solution.  See:
https://villagetelco.org/mesh-potato/

They're using Asterisk on their devices.

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Samuel Greenfeld]

The downside to SIP is that if you leave a SIP server open on the Internet
which allows calls without authenticated registration (even by accident)
you will find dozens of systems trying to proxy long-distance &
international telephone calls through it.  If they can get through,
thousands of dollars of those calls may be billed to you.

SIP also has some firewall issues, although those can be mitigated with
proxies, a STUN server, and the proper configuration.

IAX2 historically has been meant to be an "Inter-Asterisk" server trunking
protocol, not something for individual clients.

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Anish Mangal]

This looks interesting, but I would prefer to stick with SIP

Reason:
1. It is extremely scalable from running on tiny openWRT routers to big
servers
2. It is supported by a large number of free/open clients on ALL platforms.
There is also a webRTC socket for it.

The only current drawback of Kamailio right now, is there dont seem to be
ootb rpms available for arm. If there is a SIP server out there with ARM
packages, would love to test it, or otherwise - compile kamailio for ARM

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Anish Mangal]

Following from:
http://www.en.voipforo.com/IAX/IAXvsSIP.php

*If SIP is using a server* signaling messages always pass through the
server but *audio messages (RTP flow) can travel end to end without passing
through the server. In IAX, signaling and data must pass always through IAX
server. *This increases the bandwidth need by the IAX servers when there
are many simultaneous calls.


This is a big drawback of IAX it seems, especially in a mesh setup, where
in many cases, the available bandwidth between clients may be higher via
direct node routes compared with the bandwidth via the server route. It
seems SIP will utilize the network more efficiently in a mesh topology.

Yesterday we were testing this on the server, and two nodes with three
client. The data was being sent directly client -- node -- node -- client,
and virtually no bandwidth was being used on the server. :)

Hi,

A SIP server on the XSCE will allow for VOIP services (audio, video, text). 
There are numerous SIP clients on various platforms so it seems a good protocol 
and standard to build upon.

I have already included a SIP server in the upcoming deployment of XSCE and

While it is easily possible to download apks hosted by apache, using an

You are not necessarily required to create accounts *per* user, but an account 
is needed. It is easy enough to create a default account (during initial 
installation/setup itself). The default login/captive portal page can have the 
details prefilled. For example, take a look at the video:

http://people.sugarlabs.org/anish/captive.webm

In this case, I just require the user to press the "accept and login" button 
and get redirected to school.lan from there (the last bit is not in the video).


You _can_ have named accounts if you want. You can have bandwidth control per 
account as well if needed (this would obsolete wondershaper). This can be 
useful if some users have fast access and others have limited bandwidth access 
to your server (can happen in a mesh setup).

So, in sum, it is easy to have the default redirect without requiring the user 
to enter credentials, but it is possible to have credentials as well.

I think the answer to br0 is yes.


Wonderful :-)


I worry that switching dhcp providers could get tricky.


Why? In my testing so far, I havent faced any issues.

Subject: Re: Captive portal updates

Hi,

I wanted to ask whether a captive portal + radius server + radius server gui 
would be a useful feature and wanted to discuss possible implementation routes 
as this affects other services on the XSCE.

A radius server allows to have controlled access to server resources, internet 
connectivity, and allows one to create users, groups, and set aside network 
bandwidth. i.e. it is quite useful in a medium to large setup. A captive portal 
alongside it allows for good UX with notifications in phones, tablets and not 
having users to type http://school.lan.

The existing captive portal PR (#771) is a very good step in that direction, 
but I believe we will eventually need to use some kind of standard 
implementations - radius + captive portal setups.

Now that 6.1 is out of the door, I would like to propose a captive portal 
feature for 6.2.

In the current setup I am testing, I am using freeradius[1] as the radius 
server, and CoovaChilli [2] as the captive portal. Coova does it's own dhcp so 
it will have to replace dhcpd if it is used. Also, starting/stopping the coova 
services affects iptables, so initially, having it run in conjunction with 
dansguardian and squid might be a little tricky (though it is certainly 
possible, just needs more time to test/develop). Also, while freeradius is 
available as a rpm package, coova, and a dependency needs to be complied from 
source. I can create the packages for it though - it did not seem complicated.

So, the current approach I am proposing is:
1. If captive + radius is enabled, dhcpd is disabled, squid and dansguardian 
are disabled. Later, we can just have dhcpd disabled and the other two enabled 
if need be
2. If captive + radius is enabled, either we include a few knobs and levers to 
manage radius in our admin console (more difficult), or include a radius admin 
console (easier)

At the same time I have a question, since my understanding of xsce networking 
is limited. When setup in LANcontroller mode with both the internal wifi + LAN 
being controlled by XSCE, does all the LAN side traffic flow through br0? Is it 
always the case?  (in gateway mode too). If that is so, then I will configure 
coova to work on br0.

Re: [Server-devel] [XSCE] "Gigabyte BRIX more scalable than Intel NUC"

[Samuel Greenfeld]

If you are looking at devices which include sales in the US (and
potentially other) market(s), you may find that your devices may only
accept one of a few internal Wifi NICs.

This is because the FCC certification of the device as a whole is often
done including the Wifi module.  And they only expect to offer certain Wifi
modules to customers.

Lenovo and HP historically have both done this at the BIOS level.

So if you are insisting on an all-in-one solution, your wireless NIC
choices may be limited, especially now that the FCC requires proof that 5
GHz transmitters cannot be tampered with to transmit abnormally.

But if you can accept an external wifi device you may be much better off,
especially because then you can get devices which are designed to handle
lots of clients, and not primarily be a single client itself.

 Excellent information!

Curt Thompson's also recommended we look into the $130+ ZOTAC CI323 he's
had great luck with, or more to the point higher-end ZOTAC units that
accept Legit Internal WiFi modules as you describe?

(Almost anything that's not artificially capped to 12 WiFi devices, as
Intel's seems to be...)

Clarif: many of our deployments now demand that WiFi be fully contained
*inside* the school server / Internet-in-a-Box unit, keeping a lid on
endless theft/configuration/breakage/loss/sustainability hassles.

That's normal, not curious.

Please learn this; your monitor has a device that is powered over the
cable by the computer, even if the power cable is out.  The device
says "here I am and this is what I can do!".

Key words for further educational searches; Display Data Channel
(DDC), Extended Display Identification Data (EDID).

My guess is that the driver for the DisplayPort or VGA adapter needs
an update, and an examination of the kernel events may show
differences between CentOS 7.2 and Fedora 22 at the instant of
plugging.  Give it to someone technical; someone who has good
understanding of the whole stack of components.  Maybe you can get the
fix backported to CentOS 7.2.

VGA connectors are not hotpluggable.  You'll notice the pins are all
the same length.  While it often works, there's no guarantee.

Oh, look, Wikipedia says that.

"Hot pluggable: Depends"

"The VGA interface is not engineered to be hotpluggable (so that the
user can connect or disconnect the output device while the host is
running), although in practice this can be done and usually does not
cause damage to the hardware or other problems. However, nothing in
the design ensures that the ground pins form the first makek or the
last break in the connection, so hotplugging may introduce surges in
signal lines which may or may not be adequately protected against
damage. Also, depending on the hardware and software, monitor
detection is sometimes unreliable when hotplugging a VGA connection."

... complete with obligatory typo.  ;-)

Cool to have that affirmative result: even if we learned in Bellingham, WA
(LinuxFest Northwest) late April that HDMI also needs to be inserted during
NUC bootup (often? always? sometimes? anyway demonstrated by Tom Gilliard's
main NUC 4 months ago!)

For those of us living in the dark-ages-of-VGA (thru no choice of our own,
funds are limited ;) here a few (final?) concrete tips/results on this
fragile CentOS support for VGA: (compared to Fedora 22 etc)

- 4 Different Screens were tested (4 diff manufacturers, some genuinely
modern) and the result is essentially the same in all 4 cases: VGA video
rarely if ever re-appears if your VGA cable (or Mini DisplayPort adapter
cable) is disconnected after boot, no matter how briefly?

- Fun Curiosity: you can reliably pull the power cable out of the LCD
screen (or power cycle the LCD monitor with its own ON/OFF button) and VGA
video *will* quite survive amazingly, promptly re-appearing on screen,
anytime later when the monitor's power (or power cord) restores electricity!

- Bonus Trivia: if the VGA cable is disturbed/disconnected-then-reconnected
while the monitor's off, video will NOT subsequently re-appear when the
monitor is later powered on.  How on earth "God Knows" that the video cable
was briefly disconnected-then-reconnected to the monitor while the monitor
itself was off, I have no absolutely no clue..but then again I don't know
enough about the VGA protocol to attribute this entirely to Voodoo ;-)

Re: [Server-devel] [XSCE] CentOS 7 quirk: VGA cable not re-attachable

I do most of my testing of real hardware, and came across the VGA problem
also,  I've migrated to using the hdmi input to my monitor, and dongles
that translate to hdmi.  And I'm able to swap the monitor cable
indiscriminately.

I tried a different brand of LCD monitor, and the problem remains:

Fedora 22 NUC allows re-attaching of the VGA cable every time, whereas both
CentOS NUC's are highly intermittent (the VGA cable fails to show any video
upon re-attachment, the vast majority of the time).

In hindsight, the other LCD monitor (tested across all 3 NUC's) behaves
very much the same way.  Perhaps 10% of the time (or less) video
re-appears, sometimes triggered by starting/leaving X Windows using
Ctrl-Alt-F1 or Ctrl-Alt-F2 (or running "reboot" from ssh, on any machine
that was running X Windows at the time, causing video to suddenly re-appear

(NUC6i3SYH & D34010WYKH) I haven't found any repeatable pattern that
permits video to be usefully restored (without a full reboot!)

PS Problem occurs independent of CentOS 7 NUC's that are running X Windows
and those that are not.  I mention X Windows only because leaving X /

Confirmed: Fedora 22 does not have this problem, on the exact same NUC.
I've swapped hard drives between NUC's to reconfirm (in fact) the problem
results from each hard drives that contains CentOS 7, and not the other(s)
containing F22 -- regardless which physical NUC PC I insert the drives into.

No, see above :)

I'm using a Mini DisplayPort-to-VGA adapter cable, as the NUC6i3SYH
and D34010WYKH
do not take VGA cables directly.  The same adapter has been used in all
tests, across all 3 NUC's, regardless which drive was inserted.

All tests (across all 3 NUC's) were done using the same 17-inch LCD monitor.

I suppose I could try installing F19 if it was important to
assess/ascertain that CentOS 7 is inheriting this problem from a flaky
version of Fedora -- but of course I'm far more interested in a possible
fix (if such exists, as CentOS 7 will be around for many more years) rather
than playing archeologist with Fedora 18/19/20 :)

Re: [Server-devel] [XSCE] Has anyone else seen squid swap.state bloat?

[James Cameron]

You don't say why a separate partition is impractical.

The Squid intent from antiquity was that the filesystem be separate,
which in those days was only practical and performant with separate
partition or disk, with a filesystem tuned for many small files.

To use a separate filesystem yet avoid separate partitions, use a
filesystem on a loopback block device, backed by a large file.  You
will find the performance equivalent.  For example;

dd if=/dev/zero of=/squid-cache.ext4 bs=1M count=256
mkfs.ext4 -F /squid-cache.ext4
mount /squid-cache.ext4 /var/cache/squid

Experimentation with parameters to get around a Squid misbehaviour is
impractical; given your deployment feedback cycle, it could take
years; only real-world experience is valid.

Or set up a big red button "clear the cache" that is tested to work
even with a full disk.

Using a cron job to destroy the cache if disk space is short might be
a better first option; but design and test it to not require disk
space to run.

Yes, squid's model assumes that the cache that lives on a partition all by

itself with no real consideration for other programs on that partition.

Think that was the original reason for /library in the first place, maybe

we should rethink where the content/databases should reside.

https://bugs.sugarlabs.org/ticket/362. Manash is proposing to fix that.

When I read the flow chart at (1) I don't know whether it will work. Port
5000 is not a jabber server (see 2). The Authserver at (2) was written by
activitycentral, I don't know gunicorn or flask, I have not been able to
understand how it works, and I've never successfully interfaced with it.
So it makes sense to try to use port 5000.  Whether it will provide a list
of connected clients? I'm not sure (jabber seems more appropriate).  Maybe
some on this list can suggest a easy jabber client/library (nothing hit me
when I googled "python jabber client")

I'd be willing to join in a larger effort to address the problem Tony is
pointing out.  But maybe we should let Manash fix bug 362 as a well defined
task before we tackle  problems 2 and 3 below.

Background as I see it:
Problem 2:
Contrary to original OLPC assumptions, some user situations have many
children per laptop.  Should our server interactions accommodate that need?
I think we should try. I think Tony is asking us to move past original
basic assumptions.

It sounds to me that, with James suggestion about using lightdm, (which I
also have played around with), and his knowledge that on SOAS, most of the
Activities still work (with username != olpc), we have most of a solution
to the multiple identities on a piece of hardware, connected to the single
server. I know it's wrong to jump too quickly to implementation, but we
could modify the pam module makehomdir to do its normal function, as well
as enable lightdm, and disable olpc-dm.

Problem 3:
A very small number of XO's are used in a school server setting I think.
Even so, any elastic boundary between local and server journal data store
may make sense. I've heard Tony's idea about needing a journal "keep" flag
for years. And I think it's a good one. But putting it on the details page,
and not changing all the documentation relating to "favorites" flag, also
makes sense. Once we have identities unique and defined (solve problem 1
and 2), I think Tony already has working code that solves problem 3.

Yes I have been following some of the chatter around it, and thanks for the
heads up.

The model I am asking a second opinion for is a *5th* gen. Should be okay,
but still thought I'd ask. :-)

Just a warning about Intel's 6th gen, still afflicted by WHEA errors even
with the latest 0039 BIOS -- Intel is at last becoming more forthright
about the problem now under public pressure -- posting a real update today,
and promising a follow-up by April 15:

Re: [Server-devel] [XSCE] [Off Topic] More Linux users facing skype issues

[tkkang]

I have been testing the Ventrilo server on my XO1.5 XSCE and it works well. 
With connection from AP to schoolserver via my Android phone and window 
machines I can have voice conversation. There is no Ventrilo client for Linux. 
Have not been able to run the alternative Mumble client on the XO. 

Nice if XO can then be used for the voice communication as it will get 8 
children/teachers highly excited.

Cheers

Jerry could list the problems he's aware of.

But if you can get 64bit F24 running on Pine64, then you can use 
https://github.com/XSCE/xsce/wiki/XSCE-Installation#do-everything-from-scratch 
to install XSCE with ansible.  At that point you can tell us what works and 
what doesn't.

I ordered mine in Feb and am still waiting for delivery.

Not sure how they do that. If it's done with something like ansible it
would be very easy to migrate to new releases.

Jerry and George spent a lot of time migrating legacy XS code from F18 to F22.  
There is more work to get to F24.  I agree that we want to get there.

They're 32 bit ARMv7 are they not? Personally I'd be starting with
Fedora 24 as you'll have support until July 2017, instead of the 3 or
so months left for for F-22. Also for an aarch64 device F-23+ is
highly recommended.

Re: [Server-devel] [XSCE] [Off Topic] More Linux users facing skype issues

[tkkang]

Have seen my son use this and host his chat session with teammates in game play 
10 years ago. It has been around for long time and works well for him.

http://www.ventrilo.com/download.php

Nice if it can run on Sugar or can be a XSCE addon!

Also bigbluebutton is an opensource videoconferencing system.

Aside: a non-browser approach is in fact fundamental to most use cases.

The reason is that reliable calls are completely immune from browser
instability; no less searching among ~200 tabs for a live
family/community/business call Ain't Viable (!) ...even if that magical
crash-free / thrashing-free browser of the future one days appears on our
doorsteps, hahah :>

Something Google does not seem to understand yet, still a decade after
GChat etc -- everything looks like a nail, when you are the hammer?  Or
perhaps Google is/will one day face reality, issuing unobtrusive
Mac/Windows/Linux client software for Hangouts?

Conversely Microsoft is finally learning from others, offering a live URL
to Skype hangouts/calls for more open / ad hoc participation:

Re: [Server-devel] [XSCE] [Off Topic] More Linux users facing skype issues

[Adam Holt]

One of our hackers in Haiti is of course a Linux diehard, who during our
weekly call today, kept being being blocked by Microsoft's
self-contradictory (and how am I supposed to upgrade??) message-of-death:

   "[user] unable to join this call as they need to update Skype first"

So we tried to hack Skype, by restarting the large group call to/between
Linux users first, and then adding all the other user incrementally from
there: Voila it worked flawlessly!

Conclusion: there can be no mistake understanding why this is happening.
Evidently Microsoft prefers Linux over all other OS's, and so going forth
we will abide by their thoughtful pragmatism, and always begin with Linux
for a harmonious experience by all.

Looping back on this...

My PINE64 arrived in the mail today. Mine is the 2GB RAM variant, with gigabit 
ethernet, but no bluetooth or Wi-Fi (which is an add-in module)

 I actually have a couple of 200GB microSD cards that I just acquired, and I’ll 
be putting it through its paces. The SanDisk SDSDQUAN-200G-G4A retails for 
$249, but the actual street prices are $80 (on Amazon)

I suspect it will work fine in the PINE64. Does anyone here have any 
recommendations for putting XSCE through its paces, or otherwise stress-testing 
the install, besides normal benchmarking of static HTTP page load performance.

Re: [Server-devel] XSCE 6.0 Released

[Tim Moody]

Please do yourself a favor and don't just grab an image.  Have a look at the 
installation instructions first.

 

https://github.com/XSCE/xsce/wiki/XSCE-Installation

Years in the making!!  A cast of thousands!!

 

The School Server Community Edition (XSCE) version 6.0 is hereby officially 
released.  Thanks to the many contributors, developers, and testers.

 

In addition to releasing the School Server software, we have provided 
'short-cut' images for several platforms with more on the way.

 

Please read the following Release Notes and then proceed to 
https://github.com/XSCE/xsce/wiki/XSCE-Installation.

 


Release Notes for XSCE 6.0


What is it?


XSCE is the digital backbone for your education revolution. Put simply, School 
Server is an open-education project inspired by One Laptop Per Child to provide 
breakthrough digital learning tools to the world’s poorest children.


A Rose by any other Name


Internally and in the source code we refer to this software as XSCE, the 
Community Edition of the XS server originally from OLPC. Students and teachers 
often know it as Internet in a Box, a collection of educational materials and 
applications found on the internet, but available on the server even without an 
internet connection. We also refer to it as a School Server since it is aimed 
at schools and other places where people learn and performs the function of a 
server.


What's new in XSCE Release 6.0?


This release extends the tools available to educators in three ways:

*   It makes available free and open source content that is available in 
many languages
*   It provides new avenues for students to create, and share their work
*   It contains number of advances to permit easy configuration, tailoring 
of content, and monitoring of student work.


Newly Available Open Source Educational Content


*   KA Lite brings the online features of Khan Academy to the offline 
School Server based classroom. There are videos, exercises, tests, and student 
tracking in a number of languages, all selectable via a Graphical User 
Interface.  
https://learningequality.org/ka-lite/
*   Searchable offline access to Wikipedia and other content such as 
Wiktionaries and TED Talks in a variety of subjects and many languages, 
provided by the Kiwix server technology.   
http://www.kiwix.org/wiki/Main_Page
*   RACHEL (a curated selection of offline materials)  
 http://worldpossible.org/rachel/
*   Bring your own content by inserting a USB thumbdrive with content into 
the server having it immediately viewable by students.


Encourage Students to Write, Foster the Creative Process


*   Elgg provides the tools for generating social networks  
 
http://learn.elgg.org/en/2.0/intro/features.html
*   ownCloud provides client based tools for storing and retrieving 
materials stored on the XSCE local cloud.
*   DokuWiki (EXPERIMENTAL) provides a means for students to publish their 
work.   https://www.dokuwiki.org/features
*   Wordpress (EXPERIMENTAL -- enable in "local_vars") gives students 
experience editing/sharing using a tool that is becoming an industry standard.


New Tools for Administering the XSCE School Server


*   A new Graphical User Interface (Admin Console) to enable services, 
select and download content, get information
*   AWstats is a flexible tool for summarizing the web traffic on and 
through the server in graphical and detailed ways.  
http://www.awstats.org/


How do I get it?


There are three main methods of installing this software:

*   Use ansible and the git repository - this is the fall back when you 
need to customize or you have a platform for which we have not created an image.
*   Use an image you download - for some commonly used platforms we create 
image files that you can download, put on a usb stick or sd card and boot in 
your new hardware.
*   Create and use your own image - this will appeal to you if you want an 
image to use in multiple machines and are able to use the tools we provide to 
create it.

In each case you need hardware that has been assembled, but with nothing 
installed on it.

Detailed instructions on each of these methods is at  
 
https://github.com/XSCE/xsce/wiki/XSCE-Installation.

I think there is a cosmetic issue here.  I had the same problem and it repaired 
itself as soon as munin had calculated some stats later in the day and I 
rebooted.

Hi,

While testing xsce, and enabling munin from the admin console, the munin portal

(or that is what jerry suggsted is happening). 

systemctl status munin-node.service reports that it is running, and grepping

Re: [Server-devel] [XSCE] khan_assessments.zip download fails

[Tim Moody]

the easiest workaround is to have enough memory.  I bumped the vm up to 1.5G 
RAM and the problem disappeared, but this could come up if you put a large 
storage on a machine with small memory and want to run kalite with the 
assessments.

I don't think it is on extraction as that is a later task in a different .yml

Re: [Server-devel] [XSCE] Re: epiphany browser trick to force same URL every time :)

[Adam Holt]

Thanks James!

George,

In conclusion on all similar machines we prepare, let's...

1) Run:

   gsettings set org.gnome.Epiphany restore-session-policy never

2) Within /usr/share/applications/epiphany.desktop set it to:

   Exec=epiphany file:///library/index.html %U

I followed James & Jerry's "list-recursively" suggestion but could not find
another clean way to force the home/launch/start/portal page.

We'll never know what %U does but that's fine :}

3) Manually save "Internet in a Box" (URL = file:///library/index.html or
whatever appropriate for that machine!) to epiphany's Bookmarks.
Epiphany's "Not Categorized" section is just fine, in fact perfect since
epiphany since then raises the profile of this 1 bookmark, above the 20
preloaded-with-epiphany cluttered bookmarks most end users won't care about.

4) Add the following line to /bin/xs-sysprep :

   rm -f /root/.bash_history /home/olpc/.bash_history

(But do not add the following line to /bin/xs-betaprep !)

Re: [Server-devel] XSCE 6.0 RC1 for CentOS 7.1

[Adam Holt]

George,

Can you speculate why 6.0 RC 1 is only 1.8GB [1], whereas 6.0 your infamous
"Alpha 1" used by so many over the past 6 months was 2.4GB [2] ?
