Hi, Ans to Question: Yes my box has DSL interface. (h/w connecter is a RJ11). Now I have 3 types of test setup to configure and verify.. 1)DSLAM box configured to terminate a PPPoA VC-muxed connection if it has that capability. 2)Configure the DSLAM to switch the ATM (PPP) traffic from the DSL ingress interface to a regular ATM (fiber / coax) uplink which goes to a Linux server equipped with a compatible ATM NIC 3) Connecting similar 2 linux boxes back over the DSL interface one is Server(test device) other is client. Below is the test (3) result(logs) and how I executed those.. AT Server: ========== #pppd plugin pppoatm.so 8.35 192.168.42.42:192.168.42.43 passive logfile ./log.txt Arun: In PPP: start_link , FD = 7 Using interface ppp0 Connect: ppp0 <--> 8.35 LCP: timeout sending Config-Requests AT Client: ========== #pppd plugin pppoatm.so 8.35 user user1 password pass debug logfile ./log.txt Arun: In PPP: start_link , FD = 7 using channel 1 Using interface ppp0 Connect: ppp0 <--> 8.35 sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] sent [LCP ConfReq id=0x1 <magic 0x3dd022c9>] LCP: timeout sending Config-Requests Connection terminated. Modem hangup The conclusion is that, the two linx-boxes are not able to communicate. This may be due to similar NIC type ATU-R. I guess it is a hardware-mode. cannot change to ATR-C ...! Next is, I need to explore the DLSAM possibilities.. (1) & (2). In point 2 you have mentioned, "Dslam ATM uplink which goes to a Linux server equipped with a compatible ATM NIC". You mean it is client ? if server , I didn't got the point...! How is the test-setup ? , what all devices does it has..? -Arun On Thu, Jun 3, 2010 at 1:26 AM, James Chapman <jchapman@xxxxxxxxxxx> wrote: > arun b wrote: >> Well my ultimate aim is to test my client (linux-box ) i need >> responder i don't care what it is as long as it responds ... >> >> NOw just thought came to me that, what if i use 2 of linux-box one as >> server and other as client ... >> i don't know how to configure VCI/VPI on my server .. >> thses values where 9.45 as this are confiugred in our by the admin DSLAM/ ISAM. > > What physical interface is used on the PPPoA client? > > It sounds like your PPPoA client is a DSL modem.
