I can't see the HTTP packets of another computer connected in my own private network

  • retag add tags

Hi, I have just started using Wireshark software. I'm doing some tests on my home network to try to view another computer's HTTP packages. For example web pages, usernames, passwords, etc. When the other PC searches the web on my computer with wireshark there is no navigation from that IP address. How can I do? Thank you

You'll need to describe your home network a bit more. Is it wired, or WiFi?

I have a FritzBox router where a gigabit switch is connected. My two computers are connected on the switch with a network cable.

You have a switched network, in general, a device on one switch port will not see the traffic from another device on a different switch port.

See the Wiki page on Switched Ethernet for more info.

As per the wiki page::

  • Hub out:
  • Monitor mode on the switch
  • Tap
  • Machine in the middle
