Have you tried to use sudo with your commands?

Hi Jason Reiss,

That solved my issue thanks.

But I am still having problems receiving the data to the gateway.Can you please help me with the configuration?

I have installed the LoRa Gateway bridge in the gateway and also setup the packet forwarder(AEP module).I am still unable to get the data from device.

I tried the below command to check if the packet forwarder is getting the data,but no response.

sudo tcpdump -AUq -i lo port 1700

lora-network-server init script is used for both network server and packet forwarder modes

Try to run the packet forwarder manually to see if you are receiving packets

$ sudo /etc/init.d/lora-network-server stop
$ cd /var/run/lora/1
$ sudo ./lora_pkt_fwd

Is there any gateway bridge logging?

I tried the above command and this is the response i got

Using the gateway bridge I would expect the packet forwarder to connect to 127.0.0.1 or localhost.

> Network is unreachable

With this error it appears the remote server may not be accessible to the bridge anyway.

You will need to setup the network correctly.

These commands should work when the network is setup correctly

$ ping 8.8.8.8
$ nslookup google.com

Thank you.The problem has been sorted out. There was an issue with Ethernet connection. I have a LoRa GPS tracker turned on. I wanted to check if the gateway is receiving the data for which i used this command
sudo tcpdump -AUq -i lo port 1700

I followed this link.
https://www.loraserver.io/guides/troubleshooting/gateway/

I tried using this command in terminal

mosquitto_sub -h xx.xx.xx.xx -p 1883 -t application/#

but there was no response
