PPPoE Problems

I have a dual boot with XP and Debian and I'm having troubles connecting to my ADSL provier in Debian.

I have installed the latest version of rp-pppoe and followed all of the instructions for getting it going. pppd never receives a PADO from my ISP and so gives up.

The modem I have is an SVII modem (I'm in Japan and so the manual is not of any use to me) and on XP I had a few problems setting it up. Both the native XP PPPoE software and the provided PPPoE software from NTT Japan didn't appear to work. However if I connected directly to the modem by pointing my web browser at and then entered my ISP user information, and DNS servers it works fine. The modem appears to negotiate with the ISP and set up the connection directly and as far as I can tell there is no PPPoE software running, well none that I started anyway.

So on Linux I am wondering if it is possible to let the modem handle the ISP negotiating and then just "use" it so to speak. I'm new to all of this so I could be suggesting something that doesn't make sense.

The ethernet interface seems to come up fine and when pppd is trying to negotiate with my ISP the modem light blinks, so it is obviously talking to the modem OK, but it just appears to stop at the modem and not make it to my ISP.

I've tried clearing all of the connection information from the modem to try and force rp-pppoe to do the connection negotiating stuff but that didn't work. I also notice that the connection information in the log from pppd has something about connecting ppp to pts2, I don't know why it is using pts instead of eth0?

Sorry for the lack of exact log file info, but I'm obviously on XP at the moment and forgot to bring it from linux with me.

Any help would be greatly appreciated.

Hi JB,
As you are saying, I believe your modem is a router. It does the negotiation with your ISP and acts as an ethernet access server. You may try to experiment enabling dhcpcd to negotiate an address from it as normally these modems have dhcp. If you could read the manual, may be you could change its configuration to act as a bridge; then you could configure pppoe. pppd is a daemon to work with serial lines and rp-pppoe establishes a connection via ethernet and opens a virtual serial port which pppd uses to connect to the ISP.
I hope this helps a little.

Talking Working

Thanks very much osvaldomarques. You were dead right. I installed dhcp3 and when I managed to get it going ok everything seems to work fine.

Thanks for your help.
