Hi Anish

Could you clarify what is different in that way of doing things, compared
to the old way (which would essentially take weeks to generate?). I know
it's just a small country, compared to the planet, but what else is
significantly different?

 Okay, so I tried to encapsulate whatever we discussed into a design
 document, which can hopefully serve as a base for reaching out to the OSM
 community and to better organize our own thoughts.

Hi Anish

Great document. I've added 2 comments to the document, feel free to
incorporate into the document if that makes sense.

Also added a TODO for myself to do more research about the various search
solutions.
I've used Nominatim in the past (on the client side, not the server
infrastructure) and it was overall very good, but I'll want to know more
about the other ones.

Re: [Server-devel] Trying to access a school server from the outside world

[George Hunt]

Typically a server is behind some sort of NAT device, and some sort of
firewall, and most likely has a variable ip address assigned by the ISP's
dhcpd.  The trick is to have the server initiate an outgoing conversation
to a device on the internet that is always on.  I purchased a micro
instance on amazon cloud for the purpose.

The amazon instance generates keys for clients which permits passthrough
conversations between any clients. There's two levels of authentication --
1. need a vpn key to connect to the amazon instance, and 2. need
authentication at the ssh port of the target (preferably a public key in
.ssh/authorized_keys on the target -making dictionary attacks less likely).

But I'm becoming a fan of teamviewer. You need to install Xorg, and I
usually install XFCE because it's pretty light weight. Up until now, I've
resisted a GUI for servers.

Re: [Server-devel] Trying to access a school server from the outside world

[Tim Moody]

xsce listens on ssh, so if you expose that port externally you can access the 
server.  probably you don't do this as we usually put the server behind a 
firewall.

George Hunt set up an OpenVPN hub which some installs can use.  Servers connect 
to the vpn hub and connected users can then pass through the hub to the server. 
 Both users and servers need keys stored on the vpn hub.

You would need to check with Adam and George.

Re: [Server-devel] White list on xsce

[Tim Moody]

The whitelist can be edited in the Admin Console at http://schoolserver/admin.  
You need the xsce-admin user's password to login.  Go to the Configure menu 
option and it should be straightforward.

You can also turn Squid whitelist filtering on and off.

Not sure what version you have, so these features might not be there.
