Help with Wireshark Lab

retag add tags

I am trying to resolve the Wireshark Lab: HTTP v7.0 from Supplement to Computer Networking: A Top-Down Approach, 7th ed., J.F. Kurose and K.W. Ross and when I introduce the http filter no packets are shown. Why I can't see any http packets?

I have tried everything I found on the Internet and it is still not working.

You could have added a link to this freely available lab for us not to google for it.

The lab is pretty straightforward, I was able to reproduce all the steps with no problems.

have you got a reply from the server:

Congratulations. You've downloaded the file http://gaia.cs.umass.edu/wireshark-labs/HTTP-wireshark-file1.html!

in your browser?

If yes, check whether you have correct interface selected before hitting Capture button.

Hi Vlad, I changed the link to the original content, it seems you found a link to a github copy of the material.

Hi Sake, sure, got it.

Another possibility could be a disabled http dissector or one of those lower in the hierarchy (tcp, ip, ethernet). Can you see any packets if you use a display filter tcp.port == 80?
