Tcpdump: verbose output suppressed, use -v or -vv for full protocol decode Using the tcpdump host $ip command displays all traffic with one host (192.168.1.38 in this example). Sniffing on the command line can be done with tcpdump. Things become clearer when you enter icmp in the filter field and press the apply button. In total more than 200 packets were sniffed from the network. ping statistics -ġ packets transmitted, 1 received, 0% packet loss, time 0ms linux-training.be ping statistics -ģ packets transmitted, 3 received, 0% packet loss, time 2003ms Plain passwords on the command line are a security risk.I started the sniffer and captured all packets while doing these three ping commands (there is no need for root to do this): ping -c2 $ ssh 'echo | sudo -S tcpdump -U -s0 not port 22' -i eth0 -w - | sudo wireshark -k -i. You can check and find the proper one via $ ip link. It depends on its type and count off different interfaces. And the network interface (eth0) in not necessarily eth0. Port is automatically chosen by protocol specification, so not necessarily required.

Replace content in angle brackets to your needs. This enables root privileges for tcpdump on the host to be sniffed remotely. If you have no root access via ssh on your host being sniffed to, like on a raspberrypi, and for good reason you don't want to enable it or you simply can't do it, for whatever reason, there is a slightly different approach of (alternative to answer to that from we do here is to pipe the sudo password into the sudo command which executes its argument tcpdump.
