Well, unfortunately pppd won't agree to write to the ethernet device. It will only write to a device which accepts tty ioctls. If I got it correctly, what the VPN-HOWTO does is creating a pseudo, or virtual network when it has an underlying real network. In fact, it is using an existing network to create a virtual network above it. Yup, that's exactly right. My problem, putting it in a simplifying manner, is that I have the wires that connect the machine but do not have the real network above it. Hmm. Very strange that your router would want to encapsulate PPP in an ethernet frame. If you say so... Or am I wrong ? Well, I'm kinda wondering. Encapsulating ppp into ethernet frames doesn't make much sense because ethernet already takes care of framing and already has a way of identifying the protocol of the frame. As it seems to me now, I will either have to start learning the PPP source, or get myself another router. Well, maybe you could just dig a little deeper to find out about your router. BTW: How can root put raw data on the Ethernet device ? If there is no /dev for it, then how can someone open this device ? Right, there is no /dev/ device for it but then again there aren't any for any of the network interfaces. There is a way to do it but I can't think of it off hand.

PPP over an Ethernet connection.
I want to set up a *dynamic* PPP connection over an Ethernet connection (at least, that is what I think). Can you tell me what are the available tools ? Can I redirect a terminal to the Ethernet device ? There does not seems to be /dev/eth*. Suppose I'll have to hack some package, which one would you consider first ? My motivation: my_pc a_router An_ISP | | | | Ethernet Frame Realy Now my pc is connected to the router by Ethernet. The router is, actually, a frame relay adapter with routing capabilities. It accepts both native Internet protocol (IP) traffic from a direct Ethernet connection and IP data encapsulated in Async Point-to-Point Protocol (PPP - RFC 1331) or Serial Line Internet Protocol (SLIP - RFC 1055).
Re: PPP over an Ethernet connection.
It might help if you could add more information about what it is exactly you're trying to do. You can run PPP over the internet and I'd be happy to send you pre-hack netcat which will help you do this. I'm not sure the tool I have built though matches what you're trying to do. Tell me more. shaul wrote: I want to set up a *dynamic* PPP connection over an Ethernet connection (at least, that is what I think). Can you tell me what are the available tools ?

Although I'm not the original poster I'ld like to know what you're/were working on since I'll perhaps need something like this in the near future too. I have not looked into the subject yet so I do not know excatly what I want but I think it's this: Status: beeing on a private lan with a private IP and having a box doing masquerading to the inet. I want: a 'real' IP i.e. so I can ssh, etc. into my box from everywhere (port forwarding is not an option since I have no control over the masq box) I need (I think): A peer for my ppp connection which can serve me a dyn IP (no prob I hope). The ppp would go over IP through the masq box. Is there something special about this setup that would need your pre-hack in any way or can this be done using standard tools (i.e. pppd alone or such).
