I have a raspberry pi which is sending pings successfully from its IP address to the IP address of the ethernet IoT card on my mangoh red, in the raspberry pi’s command line I can see the packets are sent and received successfully with no lost packets, however I see no incoming packets on the mangoh red. Is there a way to view the incoming pings via ethernet on the mangoh red?

You can capture wireshark log by tcpdump on the interface [image] Developer Mode installs other debug/development tools such as tcpdump？ Legato Application Framework HI. I didn’t understand DeveloperMode on the website. How do I install tcpdump? I don’t quite understand what it means?

@jyijyi Is there a step by step process you can provide?

You can have a look here: https://www.wireshark.org/docs/wsug_html_chunked/AppToolstcpdump.html Download a ARM version of TCPDUMP and transfer to the module static-binaries/tcpdump at master · andrew-d/static-binaries · GitHub chmod 777 tcpdump_arm /home/root/tcpdump_arm -s0 -i eth0 -w /tmp/test.pcap

@jyijyi Okay, I downloaded the file from git hub, that was okay. It is named tcpdump and not tcpdump_arm. I transferred the file using scp (image below) [Screenshot from 2020-08-28 08-21-34] Then I changed the permission of the tcpdump file and tried to run it (image below) [Screenshot from 2020-08-28 08-19-39] with no success, all it shows is constant packets, but no clue as to what is sending these packets (image below): [Screenshot from 2020-08-28 08-26-56] I pressed ^C to end it. What do you mean in step 3?

/tmp/test.pcap is the wireshark log.

@jyijyi I still don’t understand, typing /home/root/tcpdump_arm -s0 -i eth0 -w /tmp/test.pcap just returns an error.

What kind of error is returned?

You need to use full path, /home/root/tcpdump
