i've tried some of the howtos and it seems to fail at the point where they
tell me to setup a tun device on the host OS. i did read something about
tun/tap being broken but since i don't know tun/tap at all, can't tell if
it's me doing something wrong.
i've been trying to setup hurd as a guest OS inside linux (using qemu). i've
got hurd running. just couldn't figure out the tun setup on linux to get a
network going between the host and the guest OS.
if you could post a short howto (for tun or any other ways to network the
host/guest OSs), i'd appreciate it much. if it makes things easier you can
assume both the host and the guest OSs being linux.
