[lug] Live boot network problem

[Glenn Murray]

Hi,

In Win7, under Internet Options > Internet Properties > Connections > Local
Area Network there is a check box saying to use the automatic configuration
script "http://wpad/wpad.dat".  With the help of an off-line BLUGger I was
able to set that in Firefox, and I can now browse (Tools -> Options ->
Advanced -> Network ->
Connection and Settings window with an automatic proxy configuration
field).

It seems that my problem is figuring out how to get through the Oracle
proxy on a system level, now, so "sudo apt-get update" and such will work.

Thanks,
Glenn
