NAME
     ttcp - test TCP or UDP

SYNOPSIS
     ttcp -t [ -options ] host

     ttcp-svr3 -t [ -options ] host

     ttcp-svr4 -t [ -options ] host

     ttcp-svr4-sockets -t [ -options ] host

     ttcp -r [ -options ]

     ttcp-svr3 -r [ -options ]

     ttcp-svr4 -r [ -options ]

     ttcp-svr4-sockets -r [ -options ]

DESCRIPTION
     Ttcp tests TCP and UDP network protocols; ttcp -t transmits
     data to the specified host and ttcp -r receives data.  Ttcp
     is implemented using -systype bsd43, sockets interface to
     perform network operations.

     Ttcp-svr3 functions the same as ttcp, except that it is
     implemented using -systype svr3, and uses the XTI interface
     to perform network operations.

     Ttcp-svr4 functions the same as ttcp, except that it is
     implemented using -systype svr4, and uses the XTI interface
     to perform network operations.

     Ttcp-svr4-sockets functions the same as ttcp, except that it
     is implemented using -systype svr4, and uses the emulated
     sockets interface (which in turn uses the same kernel
     streams facilities as XTI) to perform network operations.

OPTIONS
     -lnumber
          Set the length of buffers read or written to number
          (default is 1024 bytes).

     -s   When transmitting, supply data with a generated pat-
          tern; if not set, read data from stdin to be sent.
          When receiving, discard data from the network; if not
          set, write received data to stdout.

     -nnumber
          Set the number of buffers to be read or written to
          number (default is 1024).  This option is ignored if -s

          is not set.

     -pnumber
          Set the port number to connect to (when transmitting)
          or accept connections on (when receiving) to be number
          (default is 2000).

     -N   Set the TCPNODELAY option, if the -u option is not
          set.

     -Mnumber
          Set the TCPMAXSEG option to number, if the -u option
          is not set.

     -Snumber
          Set the SOSNDBUF option (when transmitting) or the
          SORCVBUF option (when receiving) to number.

     -Pprotocol
          For ttcp-svr4 only, set the name of the protocol to
          use, to be looked up in the network configuration file.

     -D   When receiving, operate as an inetd-based network ser-
          vice provider.  In this mode, ttcp expects its network
          connection to be established when it ttcp starts execu-
          tion, and to be provided as file descriptor 0.  Further
          ttcp-svr3 and ttcp-svr4 expect the inetd(1m) socket
          type configuration parameter to be
          ``stream/stream/xti'' or ``datagram/stream/xti'', and
          ttcp-svr4-sockets expects the inetd socket type to be
          ``stream/stream/socket'' or ``datagram/stream/socket''.
          When executing in this mode, ttcp writes error messages
          via the syslog(2) interface.

     -O   When transmitting, sequence number output buffers, and
          when receiving, check sequence numbers in input
          buffers.

     -C   Report local and remote connection addresses and port
          numbers.  (Default if -D set.)
