*** Draft ***



This Page outlines the steps we took to configure the new (Yawarra http://www.yawarra.com.au) provided wrap units for GHO.





For the full details & pic's refer to the GHO-Wrap-Project Case Study

(coming in may after comissioning)







We had a running image of voyage linux 0.3 so we used 

this image and copied it to the supplied 512Mb CF Flash cards.





One we set an ip address in the /etc/network/interfaces file



We proceeded with our wireless config.



We decided to use atheros 5212 based wireless cards (Ubiquiti) on our

unit but the cheaper a/b/g Wiston CM9 will work on this config as well.







Here's our interfaces file (Draft)
