1. After startup completes, double click n1 to bring up the nodes terminal
## Example Demo
This demo is uing the RF Pipe model witht he propagation model set to
precomputed.
### Failed Pings
Due to using precomputed and having not sent any pathloss events, the nodes
cannot ping eachother yet.
Open a terminal on n1.
```shell
root@n1:/tmp/pycore.46777/n1.conf# ping 10.0.0.2
connect: Network is unreachable
```
### EMANE Shell
You can leverage `emanesh` to investigate why packets are being dropped.
```shell
root@n1:/tmp/pycore.46777/n1.conf# emanesh localhost get table nems phy BroadcastPacketDropTable0 UnicastPacketDropTable0
nem 1 phy BroadcastPacketDropTable0
| NEM | Out-of-Band | Rx Sensitivity | Propagation Model | Gain Location | Gain Horizon | Gain Profile | Not FOI | Spectrum Clamp | Fade Location | Fade Algorithm | Fade Select |
| NEM | Out-of-Band | Rx Sensitivity | Propagation Model | Gain Location | Gain Horizon | Gain Profile | Not FOI | Spectrum Clamp | Fade Location | Fade Algorithm | Fade Select |
```
In the example above we can see that the reason packets are being dropped is due to
the propogation model and that is because we have not issued any pathloss events.
You can run another command to validate if you have received any pathloss events.
```shell
root@n1:/tmp/pycore.46777/n1.conf# emanesh localhost get table nems phy PathlossEventInfoTable
nem 1 phy PathlossEventInfoTable
| NEM | Forward Pathloss | Reverse Pathloss |
```
### Pathloss Events
On the host we will send pathloss events from all nems to all other nems.
> **NOTE:** make sure properly specify the right control network device
```shell
emaneevent-pathloss 1:2 90 -i <controlnetdevice>
```
Now if we check for pathloss events on n2 we will see what was just sent above.
```shell
root@n1:/tmp/pycore.46777/n1.conf# emanesh localhost get table nems phy PathlossEventInfoTable
