Wireshark:Wireshark is a software which captures packets which are in a network and will

analyze them. It will try to capture network packets and tries to display that packet data as detailed as possible. It is also a protocol analyzer or sniffer. Packet analyzer is a computer program that can intercept log over the network. Wireshark helps us find out the target packets. If we open a website, we get tons of packets with specific protocols with different colors which has its own function.

Description: Captured and analyzed packets in a specific time frame using Wireshark 1.10.5.

Summary: 1) Installed Wireshark 1.10.5 on Mac OSX 10.9.1 and XQuartz to support the

Wireshark on Mac Platform.2) Started Capturing the packets by clicking on capture in Wireshark.3) Opened the Safari Browser in which the homepage is www.yahoo.com.4) After browsing, stopped capturing the packets and started analyzing them.5) From the Wireshark software we get detailed information of all the packets

that are captured during the time frame such as Time, Source, Destination, Protocol, Length and Information.

6) Using the filter, HTTP protocol packets are filtered and the information about them are obtained by double clicking on the packet.

7) Details such as Host, Time, Location, Cookies can be obtained.

Other attachments:The analyzed Wireshark packet file will be attached along with this

document.

Result:Obtained details of the captured packets which includes Time, Source, Destination, Protocol, Length and Detailed Information of every single packet.

My queries:

1) Black coloured packets with errors2) I would like to know about some protocols which I came across while doing

this assignment:a) IGMP b) ARP

3) Can we regulate the packets in a network according to our needs? Can we control the traffic to a website?
