NAME

       driftnet - capture images from network traffic and display them in an X window; optionally, capture audio
       streams and play them.

SYNOPSIS

       driftnet [options] [filter code]

DESCRIPTION

       Driftnet watches network traffic, and picks out and displays JPEG and GIF images for display.  It  is  an
       horrific  invasion  of  privacy  and  shouldn't  be  used by anyone anywhere. It has been described as `a
       graphical tcpdump(8)', `EtherPeg for Unix', and called all sorts of nasty names by people  on  Freshmeat.
       It  is  also  possible  to use driftnet to capture MPEG audio data from the network and play it through a
       player such as mpg123(1).

       Images may be saved by clicking on them.

OPTIONS

       -h     Print a summary of usage.

       -v     Print additional details of packets captured to the terminal.

       -b     Beep when a new image is displayed.

       -i interface
              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.

       -f file
              Instead of listening on an interface, read captured packets from a pcap(3); dump file; file can be
              a named pipe for use with Kismet or similar.

       -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
              Zawinski's  webcollage.  In  this mode, no window is displayed; images are captured and saved in a
              temporary directory, and their names written on standard output.

       -m number
              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.

       -x prefix
              The filename prefix to use when saving images, by default `driftnet-'.

       -d directory
              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.

       -M command
              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 -'.

       filter code
              Additional filter code to restrict the packets captured, in the libpcap syntax. User  filter  code
              is evaluated as `tcp and (filter code)'.
