|-h||Print a summary of usage.|
|-v||Print additional details of packets captured to the terminal.|
|Listen to packets on interface. By default, driftnet will try to pick up traffic on all interfaces, but this does not work with all versions of pcap(3); on such systems, an interface must be specified. On some systems, driftnet can only use promiscuous mode if an interface is specified.|
|-p||Do not put the interface into promiscuous mode.|
|-a||Operate in adjunct mode, where driftnet gathers images for use by another program, such as Jamie Zawinskis webcollage. In this mode, no window is displayed; images are captured and saved in a temporary directory, and their names written on standard output.|
|In adjunct mode, silently drop images if there are more than number in the temporary directory. It is assumed that another process will delete images which it has processed.|
|The filename prefix to use when saving images, by default driftnet-.|
|Use directory to store temporary files. Driftnet will clear this directory of its own temporary files on exit, but will not delete the directory or any other files.|
|-s||Attempt to capture streamed audio data from the network, and either play it or, in adjunct mode, save it in files. At present this only works with MPEG data.|
|-S||Capture streamed audio data only, ignoring images.|
|Use the named command to play MPEG audio data. The command, which is executed using the shell, should accept MPEG frames on standard input. The default is mpg123 -.|
Additional filter code to restrict the packets captured, in the libpcap
syntax. User filter code is evaluated as tcp and (filter code).
