Connection between Draytek 2500We and Eee fails with "No auth is

Hello!

I wanted to connect my Asus Eee (original installation) over Wireless-LAN to my Router
Draytek Vigor 2500We. This Router is capable of those connections, my dad is able to
connect his windows-notebook (pptp/mppe).
The routers IP is 192.168.0.1. The Eee's IP is dhcp-managed (also by this router).

When I try to use ppp, it fails with the following:

/etc/ppp/chap-secrets:

So I don't know, why this fails.

Maybe you are able to help me?

Thanks a lot!

Those are a bit odd here.  Probably not harmful, though.

> hide-password		# (from /etc/ppp/options)

That's the default.  You shouldn't have to specify it.

> proxyarp		# (from /etc/ppp/options)

That's likely wrong.  It's typically used when pppd is set up to
behave as a dial-in server.

> nodeflate		# (from /etc/ppp/options.pptp)

That shouldn't be necessary.

> noipx		# (from /etc/ppp/options)

That's also the default.

He demands that you use Microsoft's proprietary MS-CHAPv2.

You don't have it configured, so you refuse.  That's the problem.  You
haven't set up your local credentials properly.

You'll need to put correct entries into /etc/ppp/chap-secrets to make
this work.

Note that you'll also want to use the pppd "user" option *instead* of
the "name" option.  The latter is designed for servers.  It may work
here, but it's not quite what you want.

Thank you very much!
I was able to resolve my problem with your help!
