Jeg har sat en e-smith server op, primært af hensyn til at få nogen
mailinglister let i luften hvilket spiller fint (med ekstra ezmlm).

Nu vil jeg gerne have VPN-funktionaliteten til at spille. Efter at
have ssh'et ind med port 47 og 1723 forwarded, og bedt om at forbinde
med PPTP til localhost i Internetopkald, får jeg følgende i loggen på
e-smith maskinen:

At insmod'e ip_gre manuelt, afhjalp ikke noget.

Nogen forslag til hvor skoen trykker? Jeg kan åbenbart ikke finde de
rigtige søgeord til Google :(
