Observe the traffic captured in the top Wireshark packet list pane.To view all related traffic for this connection, change the filter to ip.addr =, where is the destination address of the HTTP packet.Īctivity 3 - Analyze TCP Connection Traffic.Select the first HTTP packet labeled GET /.To view only HTTP traffic, type http (lower case) in the Filter box and press Enter. Navigate to the website found in your search.Īctivity 2 - Select Destination Traffic.Search the Internet for an http (rather than https) website.These activities will show you how to use Wireshark to capture and analyze Hypertext Transfer Protocol ( HTTP) traffic.Īctivity 1 - Capture HTTP Traffic Wireshark is a free and open source packet analyzer used for network troubleshooting and analysis. 9 Activity 7 - Analyze HTTP Response Traffic.8 Activity 6 - Analyze HTTP Request Traffic.7 Activity 5 - Analyze HTTP Response Traffic.
6 Activity 4 - Analyze HTTP Request Traffic.5 Activity 3 - Analyze TCP Connection Traffic.4 Activity 2 - Select Destination Traffic.Port filter will make your analysis easy to show all packets to the selected port. In case there is no fixed port then system uses registered or public ports. Now we put “udp.dstport = 67 || udp.dstport = 68” as Wireshark filter and see only DHCP related packets.įor port filtering in Wireshark you should know the port number. When we run only UDP through Iperf we can see both source and destination ports are used from registered/public ports.ĥ. Now we put “tcp.port = 443” as Wireshark filter and see only HTTPS packets. Now we put “udp.port = 53” as Wireshark filter and see only packets where port is 53.ģ. Here 192.168.1.6 is trying to send DNS query. Now we put “tcp.port = 80” as Wireshark filter and see only packets where port is 80.Ģ. Here 192.168.1.6 is trying to access web server where HTTP server is running. Ports 1024 to 49151 are Registered Ports.īefore we use filter in Wireshark we should know what port is used for which protocol.In this article we will try to understand some well know ports through Wireshark analysis. To know more about filter by IP in Wireshark, please follow below link: Port filtering is the way of filtering packets based on port number.
