/etc/network/interfaces

[Don Raikes]

Ok, so I haven't looked at wpasupplicant yet, but is there any kind of quick and dirty tutorial on how to get debian up and running on a wireless network?

I have both wired and wireless connections here, and would like ot be able to use the wireless when I move from office to office (actually from my home office to the family room :-) ).

My recollection is that you can label the connections in the interfaces file, and then bring up the right connection manually with the ifup command.

It's the right tool to use for wireless networks, especially if they're using WPa 2, as they should be for security reasons.
