Netstat can be used to diagnose network issues and service problems. Netstat is a command line utility for Linux that prints network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. The “-r” option lets you read the output of a file. The “-w” option lets you write the output of tcpdump to a file which you can save for further analysis. For example, the following command will capture the packets of “eth0” interface. Use the “ifconfig” command to list all the interfaces. How do I capture a tcpdump file in Linux? This simply means that all packets reaching a host will be sent to tcpdump for inspection. By default, tcpdump operates in promiscuous mode. Tcpdump provides a CLI packet sniffer, and Wireshark provides a feature-rich GUI for sniffing and analyzing packets. Tcpdump and Wireshark are examples of packet sniffers. When no interface is specified, tcpdump uses the first interface it finds and dumps all packets going through that interface. After capturing the packets, tcpdump will stop. Use the Ctrl+C key combination to send an interrupt signal and stop the command. It is a very well known tool for IP packet capture in Linux systems. Tcpdump is a command line utility that allows to capture the live TCP/IP packets going through an network interface and can also be saved to a pcap file for offline analysis using Wireshark tool.
