What is your network made of? Do you have several machines plugged into Ethernet ports on some device, so that you want to see the traffic from those other machines? If so, what type of device are they plugged into?

What type of device are they plugged into? Is it a cable modem or a DSL modem? Is it a hub or switch?

hub switch

There is a significant difference between a switch and a hub. So a "hub switch" makes no sens in your reply.

Can you indicate what you have done to investigate the matter yourself? That also saves everyone a ot of time asking for obvious. Please remind yourself that ALL we know is what you put in the question. In that regard I stronlgy suggest you also read about this on http://catb.org/~esr/faqs/smart-quest...

As It will help yourself a lot in getting towards your goal.

The term "switching hub" is sometimes used for switches. The "hub" in the name notwithstanding, they're switches, with the usual limitation of switches...

...namely that, even if a program is capturing in promiscuous mode, it won't see all the traffic going through the switch, because only traffic for the machine plugged into a port is sent to that port - it's not a shared medium, the way non-switched Ethernet, including Ethernet involving a true hub, is.

See the Wireshark Wiki's page on Ethernet capturing for more details.

This answer didn't satisfy the questioner last time: https://ask.wireshark.org/question/20...

This is the first time they've used the word "switch", so at least now we can authoritatively say "you can't".
