Hi James, Yes I am convinced with your schismatic-presentation, now I know what exactly it need to run server. And I would say, it is not possible for me to test PPPoA because. 1) As we neither have DSLAM with uplink is ATM path nor the built in support for PPP, rather it has only Ethernet-uplink . 2) Also do not available of any Linux-server which terminates the ATM-path. So I will have to explore the possibility, how can I arrange this...! So one doubt again, Could you please name the know-standard-devices (manufactures/makes) for Linux-server in the below diagram, which has support of similar server-command mentioned by you in the previous e-mail. -Arun On Thu, Jun 3, 2010 at 2:51 PM, James Chapman <jchapman@xxxxxxxxxxx> wrote: > arun b wrote: >> Hi, >> >> Ans to Question: Yes my box has DSL interface.
