Howzit,
what billing systems/usage trackers are you ppl running?
Running a small wisp here and need to add some per MB billing rather than uncapped for our 100 odd users. Any ideas.
Take a look @ WHMCS it very powerful and you could write / purchase / get someone to write you anything you need if what you need isn't included already
Sigh people. Please read his thread! He's not looking for an invoicing system. He wants AAA/RADIUS.
Get Radius Billing Manager as stated above. But first wait a bit, newest version is coming out soon, which uses freeradius 2.x rather than 1.8.x + load of new features.
Or you can just use USERMAN that comes with Mikrotik, but it sux.
