NAME

   tcpprof  report profile of network traffic

SYNOPSIS

   tcpprof [-?hdnpR] [-f filter expr] [-i interface] [-P port] [-r filename] [-s seconds] [-S letters] [-t lines]

DESCRIPTION

   tcpprof reports a profile of network traffic by ranking it by link type, ip protocol, TCP/UDP port, ip address, or network address.

   Network  information  is collected either by reading data from filename, or by directly monitoring the network interface interface.  The default action for tcpprof is to automatically
   search for an appropriate interface, and to generate a profile before it exits.

   When reading data from filename, tcpprof will display the profile and exit immediately after the entire file has been processed.  When collecting data  from  interface,  tcpprof  will
   keep running unless the -s option had been specified.

OPTIONS

   The options are as follows:

   -f filter expr
               Filter the packets according the rules given by filter expr.  For the syntax of these rules, see tcpdump(1).  The argument must be quoted if it contains spaces in order to
               separate it from other options.

   -h, -?      Display version and a brief help message.

   -d          tcpprof  will track the source and destination information separately, where applicable, and identify source data with a ">" and destination data with "<".  For example, a
               "http <" statistic signifies all traffic with destination port 80 (http). This option only applies to port, host and network statistics.

   -i interface
               Do a live capture (rather than read from a file) on the interface interface given on the command line.  If interface is "auto" then tcpprof tries to  find  an  appropriate
               one by itself.

   -P port     This  tells tcpprof to ignore TCP and UDP ports greater than or equal to port when displaying port statistics.  This is not the same as filtering these port numbers out of
               the data set.  This way, packets with i.e. the source port above port and the destination port below port will be able to still count the lower port number as a statistic.
               In addition, this doesn't affect the other statistic types (link, protocol, etc.)

   -p          Set the interface into non-promiscuous mode (promiscuous is the default) when doing live captures.

   -r filename
               Read all data from filename, which may be a regular file, a named pipe or "-" to read it's data from standard input.  Acceptable  file  formats  include  pcap  (tcpdump(1)
               files) and "snoop" format files.  filename is usually a file created by the tcpdump(1) command using the "-w" option.

   -S letters  Tells tcpprof which statistics to display.  letters must be a string of one or more of the following letters:

               l     show stats about the link layer

               i     show stats about all ip protocols

               p     show stats about TCP/UDP ports

               h     show stats about hosts/ip addresses

               n     show stats about network addresses

               a     a synonym for "liphn"

   -s seconds  When monitoring an interface, tcpprof runs for only seconds seconds, and then quits.  Has no effect when reading data from a file.

   -t lines    When printing a profile of the data, tcpprof will display a maximum of lines lines for each statistic.

SIGNALS

   Upon receiving a SIGINT, tcpprof will print any remaining statistics, and then exit.

FILES

   /dev/bpfn    the packet filter device

EXAMPLES

         tcpprof -i fxp0 -S a

   Displays a complete profile of network data passing through the fxp0 network interface, after the user enters ^C (control C).

         tcpprof -r file.dump -S a

   Displays a complete profile of network data from the tcpdump(1) generated file "file.dump".

HISTORY

   tcpprof  was  first  written  along side tcpstat in Winter 1998 using FreeBSD 3.0, and then finally retrofitted for Linux in Spring 2000.  It became installed along with tcpstat since
   version 1.5.

BUGS

   Not tested with link types other than Ethernet, PPP, and "None" types.

   There may be problems reading non-IPv4 packets across platforms when reading null type link layers.  This is due to a lack of a standardized packet type descriptor in libpcap for this
   link type.

   Snoop file formats cannot be read from stdin or named pipes.
