The mininet container cannot use xterm and wireshark #120

Open pth2000 opened 7 months ago

Hello,

When I execute 'xterm h2' in mininet, I get the following error:

Error: Cannot connect to display

I think this has something to do with docker containers. This prevents me from running wireshark on any host.

In Exercise 6: Segment Routing v6 (SRv6) it is mentioned that:

To verify that the device inserts the correct SRv6 header, you can use Wireshark to capture packet from each device port.

How should I run wireshark to capture the packet?

If anyone can help, thank you!

Hi. I found some alternatives to the above problems.

Edgeshark can help you capture packets of all links in docker network.
Regarding the terminal, here are some temporary solutions.

Cheers!

Thank you so much. I am stuck on another thing that I want to run the topology with ipv4 hosts in it but I am facing the problem that the hosts are unable to ping each other. Can you help me in this regard please?

I haven't studied ngsdn further recently, so I may not know much about this issue. I'm concerned that the P4 forum is still active. Maybe someone in the forum can answer your questions.

Cheers!
