I've recently started learning to use TCPdump, and I find it pretty interesting. There's one thing I don't understand. When I tell it to capture packets on, say, the WiFi interface en1, it often captures packets sent or received by other hosts on the network. How can it do this? My... (3 Replies)

ovs-tcpundump(1) Open vSwitch Manual ovs-tcpundump(1) NAME
ovs-tcpundump - convert ``tcpdump -xx'' output to hex strings SYNOPSIS
ovs-tcpundump < file Common options: [-h | --help] [-V | --version] DESCRIPTION
The ovs-tcpundump program reads tcpdump -xx output on stdin, looking for hexadecimal packet data, and dumps each Ethernet as a single hexa- decimal string on stdout. This format is suitable for use with the ofproto/trace command supported by ovs-vswitchd(8) via ovs-appctl(8). At least two -x or -X options must be given, otherwise the output will omit the Ethernet header, which prevents the output from being using with ofproto/trace. OPTIONS
-h, --help Prints a brief help message to the console. -V, --version Prints version information to the console. SEE ALSO
