pptp client installation, no ppp0 device

My config is here. Module pppoe is modprobed, but there's no ppp0 device; i.e., it does not appear in the output of ifconfig -a.

I am trying to establish a pptp link over the internet to my place of work. I have a remote hostname, a user name and password. I tried:

Already seen that. Nothing relevant.

BTW, /dev/ppp does exist.

Now I'm thinking ... I want to tunnel over ethernet so should there actually be a separate device for that? Maybe ppp0 is for serial lines only, which I absolutely don't want.

mounty1,

pppX is a dynamically created interface, so it only appears in ifconfig once its up.
If you expect to see ppp0, you need a way to authenticate with the remote end before ppp is started to create ppp0.

Many VPNs, there are several sorts, do not generate extra interfaces in Linux.

mounty1,

It would help if we knew the name of the package on the remote end that you are trying to connect to.

VPNs don't normally let you connect with just a username an password as that does not provide any encryption.
There is normally a shared secret (there are other ways of passing an encryption key) used to encrypt the traffic in the tunnel.
Whatever, its the encryption in the tunnel that provides security, not the tunnel itself.

The tunnel is just IP traffic wrapped in another IP traffic layer.
The outer layer uses the public IPs of both end points the inner layer is whatever you want.

How do you generate encrypted traffic for the tunnel?
Different systems do different things.

Thanks for the help so far and sorry for the delay in replying; I was diverted to other matters.

To answer Neddy's question: I'm connecting to a Windows server.
