![]() ![]() In similar lines, let’s try to generate and capture the SSH packets from the loopback interface: $ ssh localhostĠ6:30:52.419160 IP localhost.43398 > localhost. In the first session, we initiate the packet capture on the loopback interface, then we will execute a simple ping to localhost: $ ping -c 1 localhostĠ6:24:36.453843 IP localhost > localhost: ICMP echo request, id 19865, seq 1, length 64Ġ6:24:36.453854 IP localhost > localhost: ICMP echo reply, id 19865, seq 1, length 64 Figure 4-5: Sample localhost ICMP traffic Windows and Localhost In. If we want to monitor the packets from the specific interface, we can use option -i.įor the sake of demonstration, let’s open two PuTTY sessions. Wireshark can easily attach to this interface and sniff packets destined to localhost. ![]() Most correspond to physical network cards there's a 'loopback' one for 127.0.0.1 as well. Each packet gets routed to a specific network interface. Just tell Wireshark to monitor the VPN interface, not the actual Ethernet/WiFi one. Tcpdump has many options to parse, search and filter the network interface traffic. 661 2 8 15 Add a comment 2 Answers Sorted by: 17 Sure. ![]()
