<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Eustace,<br>
<br>
I will try to answer your questions -- if you think you will need more help, please
do post your questions to <a href="mailto:server-devel@lists.laptop.org">server-devel@lists.laptop.org</a>
-- I will set the list so that your messages come through, and we'll help you
there.<br>
<br>
First - the ISP info sounds reasonable, you will need to put those IP addresses
& netmasks in the "eth0" configuration -- see notes here <a
href="http://wiki.laptop.org/go/XS_Techniques_and_Configuration#Setting_a_static_IP_address_for_eth0">http://wiki.laptop.org/go/XS_Techniques_and_Configuration#Setting_a_static_IP_address_for_eth0</a><br>
<br>
If you want to use OpenDNS, you will have to _ignore_ the ISPs own DNS servers.
They may prevent you from doing that - so my recommendation is: get things
started using the ISPs DNS servers. Once it's all going (so you know you're
configuring things right), try to switch to the OpenDNS servers -- if it
doesn't work... well... it's probably that the ISP is blocking it. <br>
<br>
In some cases, it makes sense for an ISP to block this traffic (there some
malicious DNS servers out there). Consider asking them to make an exception for
OpenDNS -- which is a well known non-malicious DNS service.<br>
<br>
Under linux - and specifically because this is a server that in itself provides
DNS services -- you have to set the DNS servers in a special config file. See
the notes here <a
href="http://wiki.laptop.org/go/XS_Techniques_and_Configuration#Use_OpenDNS">http://wiki.laptop.org/go/XS_Techniques_and_Configuration#Use_OpenDNS</a><br>

Yes, you need to read the Installation guide, and then pick and choose what
parts of the "techniques and configuration" page you want to use /
apply.<br>
