3. Access the network through a "tuntap" interface.
The "ethernet card description" must be set to "tun".
TUN/TAP provides packet reception and transmission for user
space programs. It can be viewed as a simple Point-to-Point
or Ethernet device, which instead of receiving packets from a
physical media, receives them from user space program and
instead of sending packets via physical media writes them to
the user space program.
A virtual network configuration script is required and the
default is /usr/local/BasiliskII/tunconfig unless you specify
a different file with the "etherconfig" item.
This script requires you that "sudo" is properly configured
so that "/sbin/ifconfig" and "/sbin/iptables" can be executed
as root. Otherwise, you can still write a helper script which
invokes your favorite program to enhance a user priviledges.
e.g. in a KDE environment, kdesu can be used as follows:
#!/bin/sh
exec /usr/bin/kdesu -c /path/to/tunconfig $1 $2
