Read More on : How to Install and Use Wireshark on Debian 9 / Ubuntu 16.04 Example:7) Capturing only IP address packets on a specific Interface (-n option) Reading from file enp0s3-26082018.pcap, link-type EN10MB (Ethernet) Reading the packets with human readable timestamp, ~]# tcpdump -tttt -r enp0s3-26082018.pcap In the above example we have saved the captured packets to a file, we can read those packets from the file using the option вЂ -rвЂ, example is shown below, ~]# tcpdump -r enp0s3-26082018.pcap Tcpdump: listening on enp0s3, link-type EN10MB (Ethernet), capture size 262144 bytesД¬apturing and Saving the packets whose size greater than N bytes ~]# tcpdump -w enp0s3-26082018-2.pcap greater 1024Д¬apturing and Saving the packets whose size less than N bytes ~]# tcpdump -w enp0s3-26082018-3.pcap less 1024 Example:6) Reading packets from the saved file ( -r option) LetвЂ™s assume i want to save the captured packets of interface вЂњ enp0s3вЂќ to a file name enp0s3-26082018.pcap ~]# tcpdump -w enp0s3-26082018.pcap -i enp0s3ДЄbove command will generate the output something like below, ~]# tcpdump -w enp0s3-26082018.pcap -i enp0s3 LetвЂ™s assume we want to capture 12 packets from the specific interface like вЂњenp0s3вЂќ, this can be easily achieved using the options вЂњ -c

~]# Example:2) Capturing specific number number of packet from a specific interface

Output would be something like below, tcpdump: verbose output suppressed, use -v or -vv for full protocol decode LetвЂ™s assume, i want to capture packets from interface вЂњenp0s3вЂќ ~]# tcpdump -i enp0s3 When we run the tcpdump command without any options, it will capture packets on the all interfaces, so to capture the packets from a specific interface use the option вЂ -iвЂ followed by the interface name. In this tutorial we will discuss how to capture and analyze packets using different practical examples, Example:1) Capturing packets from a specific interface So to stop or cancel the tcpdump command, type вЂњ ctrl+cвЂќ. When we run the tcpdump command without any options then it will capture packets of all the interfaces. On RPM based Linux OS, tcpdump can be installed using below yum command # yum install tcpdump -y
