It includes the packet number, time, source, destination, protocol, length, and info. 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. It determines the packet flow or the captured packets in the traffic. 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
ip address show 1: lo: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. Determine the network interface you wish to monitor for capturing network traffic. Update: After the tests from Kurt below and my own tests on Network Monitor 3.4 it appears that the MS capture applications cant capture localhost traffic either.
Underneath the main icons at the top, you will see a line that begins Apply a. Tcpdump has many options to parse, search and filter the network interface traffic. Capturing localhost traffic (on Windows) can be a bit of a challenge, because when you send messages to 127.0.0.1 the internal network driver typically. IMHO the simplest answer here is to use Network MonitorMessage Analayzer from Microsoft to capture the traffic, then use Wireshark to inspect the captures. Thankfully, this can be done easily by applying filters to your traffic captures.
