# 6LoWPANd

6LoWPANd must be run as root in order to create the new network adaptor in the kernel using the tun driver. The only required parameter is the serial port to which the Border-Router node is connected.
```
root@localhost # 6LoWPANd –s /dev/ttyS0
```
Many other parameters of the IEEE802.15.4 network can be set via command line options to 6LoWPANd.
Once 6LoWPANd has started and is connected to the Border-Router node, it will create a new network interface named `tun0` (This may be configured via the `–interface` parameter to 6LoWPANd. This interface must be brought up and given a valid IPv6 address. A link local address is all that is required. A route to the IPv6 prefix of the JenNet-IP network may also be set up.
```
root@localhost # ifconfig tun0 up
root@localhost # ip -6 addr add fe80::1 dev tun0
root@localhost # ip -6 route add /64 dev tun0
```
6LoWPANd saves this in a text file named `/tmp/6LoWPANd.`, as well as establishing an address record with Avahi if Avahi support was compiled in. It should now be possible to ping the IPv6 address of the coordinator.
```
root@localhost # ping6 `cat /tmp/6LoWPANd.tun0`
PING fd04:bd3:80e8:2:215:8d00:12:147d
(fd04:bd3:80e8:2:215:8d00:12:147d): 56 data bytes

```
Once the localhost can ping the IPv6 address of the Border-Router node, the routing information for other machines on the LAN can be set up to allow them to also route to it. This can be set up manually as follows. First, determine the link local address of the Ethernet interface of the Border-Router via the command `ip -6 addr`:
```
root@localhost # ip -6 addr
1: lo: mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
3: eth0: mtu 1500 qlen 1000
inet6 fe80::224:a5ff:fed8:1240/64 scope link
valid_lft forever preferred_lft forever
```
Once the link local address is known, a route to the IPv6 prefix of the JenNet-IP network can be set up on another machine via the following commands:
```
root@localhost # ip -6 route add /64 via dev eth0
```
The Machine must also be given an additional IPv6 address with global scope so that it can send packets off link to the JenNet-IP network using the following commands:
```
root@localhost # ip -6 addr add fd04:80e8:bd3:1::2 dev eth0
```
Following this, the machine should also be able to ping the IPv6 address of the Border- Router node.
