Log / Dialup admin Nas lookup

[Cris Boisvert]

Freeradius fedora core 3
Mysql with dialup admin..

Is their a way to have the dialup admin show all the users that have logged
in to one 
Nas Server in a one month period? But not list all the login and accounting
info?

I just need a list of the users not everytime each logged in.

Currently I do this.. From the radius.log


Cat radius.log | grep nasserveraddress > NEWFILE

Then I import the file and sort them and delete all the login lines but
one..

Any recccomenddations?

Thanx
Cris
