Re: Network manager not handling interfaces

[Githin Alapatt <githin gmail com>]

Thanks Dan!
Those are very much possible. I recently upgraded from lenny to
squeeze using apt-get dist upgrade.

However, if I configure my eth0 card using the
/etc/network/interfaces, things work perfectly.

I used ndiswrapper previously to get my wlan working in lenny. Worked
perfectly for 2 years until the upgrade.

May be I did not upgrade correctly.

Here are the outputs.
