hi,
Thanx Julian for pointing me to the tunnel pseudo-driver.
But my major concern was regarding linking the driver to the kernel( i
am trying to use static linking stuff). I am presently doing
a major grep on "tun" 8-)
It would be great if i could get some docs regding which files
have to be modified so that the kernel realises my driver. So far
i could figure out that the below files have to be modified( did i leave
anything ????)
/usr/src/sys/i386/conf/*
/usr/src/sys/conf/majors
/usr/src/sys/conf/files
Do i really have to modify the /usr/src/sys/modules/* files???
