It's quite hard to experiment over SSH to a remote
host unless you have two ethernet cards and can SSH
through one whilst configuring the other. In order to
attach our ethernet device (ethX) to the bridge we need
to assign it an IP of |

If we want to allow users to run UML sessions that attach
themselves to tun devices on the host they need access to
/dev/net/tun. One way of
allowing this is to add a group called "uml" and put the
users that run UML sessions into this group. A typical
/etc/group entry might look
like "uml:x:104:david", or
you may wish to use your distributions addgroup or groupadd command.
Now that we have created the group we need to make sure
/dev/net/tun is owned by the
group "uml" and that the group has access to it.
#chown root:uml /dev/net/tun#chmod 660 /dev/net/tun
