<div dir="ltr">Problem 1:<div>Sugar now has a "register again" which I have only used to connect to the same server. I guess that it's hard to do a ssh connection to a different server (same IP) without ssh complaining about a possible man in the middle attack. This is the situation described in <a href="https://bugs.sugarlabs.org/ticket/362" target="_blank">https://bugs.sugarlabs.org/ticket/362</a>. Manash is proposing to fix that.</div><div><br></div><div>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")</div><div><br></div><div>I'd be willing to join in a larger effort to address the problem Tony is pointing out.

Should our server interactions accommodate that need? I think we should try. I think Tony is asking us to move past original basic assumptions.</div><div><br><div>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.<div><br></div><div>Problem 3:</div><div>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.</div><div><br></div><div>(1) <a href="https://wiki.sugarlabs.org/go/Features/Multiple_schoolserver_registration">https://wiki.sugarlabs.org/go/Features/Multiple_schoolserver_registration</a></div><div>(2) <a href="https://github.com/XSCE/xsce/blob/master/roles/authserver/tasks/main.yml">https://github.com/XSCE/xsce/blob/master/roles/authserver/tasks/main.yml</a></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Apr 13, 2016 at 5:30 PM, Adam Holt <span dir="ltr"><<a href="mailto:holt@laptop.org" target="_blank">holt@laptop.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr">On Wed, Apr 13, 2016 at 8:17 PM, Tony Anderson <span dir="ltr"><<a href="mailto:tony_anderson@usa.net" target="_blank">tony_anderson@usa.net</a>></span> wrote:<br><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">James<br>

However, the XOs access the schoolserver based on SSID and so users can be divided to their own schoolserver by the connection - defining the LAN.<br>
<br>
The OLE Nepal solution clearly satisfies the requirement to avoid any unnecessary configuration option or 'onboarding' step.<br>
<br>
The current placement of the code has been working for years. Showing the server in the network section was added at a late release, as I recall because the register menu item disappeared after registration and so a user did not know for sure if the XO was registered. This was later fixed with 'register again' so putting the name in the network section is now redundant.<span><br>

Hi Jerry,<br>
<br>
Please don't forget jarabe/desktop/schoolserver.py is involved, I<br>
personally would prefer that code to be moved into<br>
control-panel/network.<br>
Others please chime with your thoughts on this one.<br>
<br>
Yes, if register option is brought to network section, then it will<br>
provide<br>
better space for managing multiple different XS servers.<br>
</blockquote>
Yes, add registration function to the network section, or move server<br>
to a new section ... but for ease of first-use where only one server<br>
is present, the register option can remain on the main menu.<br>
<br>
(Why do I suggest a new section? The Network section has become<br>
cluttered with radio device controls, access point cache control,<br>
jabber server, social help, and soon proxy settings.)<br>
<br>
</blockquote>
Wouldn't the backup related fields be more relevant in the backup section<br>
of control-panel? Maybe the 'new' proxy settings could have its own control<br>
panel section also?<br>
</blockquote>
Yes, yes.<br>
<br>
