Your knowledge to share with us is appreciated as your discussed a critical topic about routers, switches and hubs. These devices are confusing a bit so i really enjoyed seeeing your video about this. Thanks Y.O.U.S.A.F
Technically, hubs don't actually send traffic out all ports. A hub must never emit a frame out the same port it was received on.
Hubs are big and clunky.
One can make a custom sniffing cable that has 4 connectors (two connectors at each end of the cable), where the sniffing ends have nothing connected to the TX pairs, so the sniffer cannot transmit, and the switch won't see you.
Modern switches have the ability for the admin to configure mirror, SPAN, or MONITOR ports.
Not really, but they have to be very close to you on the network (between you and the switch). The switch can be set to send an alert when two hardware devices are sharing the same port, but sniffers can be configured to only listen and never broadcast anything. You could use encryption, like a vpn or https session but that is the only protection.
Are you going to ever do a video on protecting from wardriving ? I ask because I can't help but wonder how many people have open AP's out there just because they don't know or don't even do anything extra like mac address filtering for added protection...
Great video. It would have been better if TechAnvil could name the sessions in the way to be seen, I am little confused which one comes first and next.
That will be great. May be u could create an index and put in your main page. Newbees like me, dont know whcich sequence of vdos to see. It will suerly be a great help.
Eh. I knew hubs were no good where I work. Where I work they're a violation of policy, and it's interesting to know that some random person could hook up an extra wire, run it through nearby spaghetti, and hook up a port sniffer to spy on people's computer use. =)
thanks for the information but i already know it but thanks any way

Very nice and very straightforward! Thanks!
Additionally, a router includes an ethernet switcj plus other services like Network Address Translator, a Hardware firewall, DHCP server, DNS, etc.

YOU SHOULD PUT TOOLS, GADGETS IN SINGLE FRAME,that one can freeze the image and has an overview.

Is there a way to protect yourself from being sniffed by someone inside a network using a hub?

Nope. Hubs are stupid, they simply repeat all packets to everyone.

"ARP Cache poisoning" Sounds like a good CCIE lab question.

Yes, I have at least 3 WiFi shows coming up. They take a little longer to shoot, so I have to work them into my schedule.

I have been thinking about just that. DO you think I should split them up by topic?
