# NETWORK (tun/tap) |

# Host configuration |
| 76 |
For Tun/tap to work, it must be compiled in or as module of the hosts kernel |
| 77 |
Install package uml-utilities which includes needed binary 'tunctl' , e.g. on Debian do: |
| 78 |
:#apt-get install uml-utilities |
| 79 |
|
| 80 |
# create tun network dev only if it does not exists |
| 81 |
mkdir /dev/net (only if not exists!) |
| 82 |
mknod /dev/net/tun c 10 200 |
| 83 |
|
| 84 |
# create tap device(s) |
| 85 |
tunctl -u <userid> <tap-device> |
| 86 |
e.g. |
| 87 |
tunctl -u barny tap2 (example if tap0 and tap1 already exists) |
