has anyone successfully been able to set up pptpd on debian on linode?

Im basicly trying to set up a vpn server (compatible with winxp) that creates a local area network between the vpn connected clients.

Im getting wierd error msgs left right and centre.. thats when it actually connects.. ppp seems to crash constantly..

anyone have a howto or know how to set this up properly? or anyone else had the same kinda problems

with a custom compiled ppp :-

I've gotten it to work, by dispensing with the Debian ppp package and compiling ppp-2.4.2 from a tarball, along with PoPToP. However, I have not been able to get MPPE encryption to work, even with kernels that have had MPPE support compiled in. I've abandoned the idea of using a VPN to the Linode because of this. By comparison, my FC1 box at home works fine with MPPE. I might try OpenVPN some time (it's SSL-based rather than PPTP), but I'll need to get some more round tuits before trying it. The drawback, of course, is that Windows doesn't have built-in OpenVPN support...

So i managed to find a patch for ppp that fixes the mppe type thing problem and i log in, it says registering on the network, ten it crashes.. now i think that just might be my firewall at home.. but i still need to check that.. effort of unpluging cable modem from router and directly into my computer is still very hard to find at the moment :P

ill check it after work tonite and get back to you guys..
i think it should be doable

cheers
