TCPPROF(1) General Commands Manual TCPPROF(1) 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 inter- face, 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 col- lecting 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 in- terface 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) gener- ated file "file.dump". SEE ALSO tcpdump(1), pcap(3), bpf(4) HISTORY tcpprof was first written along side tcpstat in Winter 1998 using FreeBSD 3.0, and then finaly retrofited for Linux in Spring 2000. It became installed along with tcpstat since version 1.5. AUTHORS Paul Herman <pherman@frenchfries.net> Cologne, Germany. Please send all bug reports to this address. 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.
