[Techtalk] Basic connection questions

[Maria McKinley]

I see no reason why this isn't a fine place to post this question.

When NM first came out, I had some luck with uninstalling it and using
/etc/network/interfaces, but lately this hasn't worked, except on netbooted
machines. I'm not sure why exactly, but seems the powers that be really
want you to use NM. :/ I have found it to be less flaky then it use to be,
fwiw. I haven't tried it, but there are some configuration settings
outlined in this page

http://wiki.debian.org/NetworkManager

that enables NM to use network/interfaces, and do some other stuff that
gives you more control using configuration files instead of their tools.
Seems like this stuff should also work on Ubuntu.

cheers,
Maria
