1. First step is to create a special FIFO file using mkfifo command, where you want to see the packet capture using WireShark. This file will use to read & write simultaneously using WireShark & tcpdump.

mkfifo /tmp/packet_capture

2. Second give the following ssh command on your terminal, to start the tcpdump on remote PC.

ssh hostname_or_ip_of_remote_pc "tcpdump -s 0 -U -n -w - -i eth0 not port 22" \
 > /tmp/packet_capture

3. Third & last step, give the following command to start the WireShark on your PC, which will read packets from the special FIFO file ‘/tmp/packet_capture’ at runtime.

wireshark -k -i /tmp/packet_capture

After giving the above command all the packets of remote pc’s eth0 will be visible on WireShark.
