Is it possible to find the packet transferred in another device ( Say TV, STB ) in the same network using wireshark ? asked 24 Mar '15, 21:23  Magesh Gopal... |
One Answer:
It depends. It depends on the network media, is it wired Ethernet or Wireless and it depends on the components in the network, e.g. is there a router, switch or hub. Capturing on a broadcast network such as WiFi can be done given a suitable wireless NIC, drivers and OS (note Windows is deficient here, without special hardware such as an AirPCap adaptor). See the Wiki page on Wireless Capture. Capturing on a wired network usually needs the cooperation of the switch to mirror traffic, or the insertion of a hub or tap. See the Wiki page on Ethernet Capture. answered 25 Mar '15, 06:40  grahamb ♦ It is connected with wired . (25 Mar '15, 07:54) Magesh Gopal... OK, so presumably both your PC and the two STB's are connected to a router of some sort, what is that device? (25 Mar '15, 07:59) grahamb ♦ It is a de-link connector. (25 Mar '15, 10:00) Magesh Gopal... Presuming you mean a D-Link router, then it's likely acting as a switch and as they're generally "home" class devices it won't easily span or mirror a port. Again I refer you to the Wiki page on Ethernet Capture in particular the section on switched Ethernet. (25 Mar '15, 10:19) grahamb ♦ |
The simple answer is yes. A computer with Wireshark and WinPcap will capture all network traffic when connected to a network. Now you need to find some kind of marker in the packet (MAC address, IP address, protocol used, etc.) to determine which packets are coming from/going to the device of interest. Can you post a capture to either dropbox or google drive and provide the link here?
Okay Guys. Can you please tell me how it is ?
For Example:- My PC IP is :- 10.197.13.88(Runing Wireshark and WinPcap) , My STB Ip is : 10.197.13.89
If I want to collect the packet transferred between my STB(10.197.13.89) and other STB( Say 10.197.13.90) with Same network.
What Can I do to collect the packets from my PC.
Line by line explanation helps me more, For easy understanding.
Picture representation also help me!!!
Waiting for your response !!!1
So how are these device connected, wired Ethernet, WiFi or something else?
Please make yourself familiar with the Wiki contents referenced in the answer. This will guide you in the right direction.
