hello, i need help with counting the total traffic for e.g i have a client named pppoe-james how can i know the total traffic(upload & download) that he used. plz i need help
As you are using PPP already I think your best solution would be to install a radius server and let it do the accounting (maybe with Acct-Interim-Interval if you have long-running sessions and need up-to-date accounting values even during the lifetime of a users session).
