NAME

     rds-gen — write data from a file to an RDS socket

     rds-sink — write data from an RDS socket to a file

SYNOPSIS

     rds-gen [-s source_address:source_port] [-d destination_address:destination_port] [-f input_file]
             [-m message_size] [-l total_bytes] [-i interval]

     rds-sink [-s listen_address:listen_port] [-f output_file] [-i interval]

DESCRIPTION

     The rds-gen and rds-sink utilities are used to stream data through RDS sockets.  rds-gen reads data from a
     file descriptor and sends it as messages down an RDS socket.  rds-sink receives messages from an RDS socket
     and writes it to a file descriptor.

     The following options are shared between rds-gen and rds-sink:

     -s address:port
             Binds the RDS socket to the given address and port.  rds-gen will send messages from this address
             and port.  rds-sink will receive messages sent to this address and port.

     -f file
             rds-gen will read data from this file and rds-sink will write data to this file.  If '-' is given
             as the filename then rds-gen will use standard input and rds-sink will use standard output.

     -i interval_seconds
             An iterative summary of the number and size of messages that are sent and received is written to
             standard error at this interval.

     In addition, rds-gen supports the following options:

     -d address:port
             Messages are sent to this destination address and port.  If this option is specified multiple times
             then the messages are sent to each destination address in a round-robin fashion.

     -m message_size
             Specifies the size of the messages that are sent down the RDS socket.  The default message size is
             4k.  The message size must not be greater than the buffer size.

     -l total_bytes
             Specifies the number of bytes that will be sent out the socket before rds-gen exits.  If this is
             not specified and rds-gen was given a source file then it will run until it gets EOF from the file.
             If no file was given and this option is not specified then rds-gen will send data indefinitely.

EXAMPLES

     rds-gen on host src sends infinite data to rds-sink on dest who prints out the amount of data it receives
     every second.

           $ rds-sink -s dest:22222 -i 1
           $ rds-gen -s src:11111 -d dest:22222

     Read 100M from /dev/zero on src and write it to /dev/null on dest, printing stats on both sides every
     minute.

           $ rds-sink -s dest:22222 -f /dev/null -i 60
           $ rds-gen -s src:11111 -f /dev/zero -d dest:22222 -i 60

     Watch rds-gen write data as fast as it can into a local black hole because there is no bound receiving
     socket.

           $ rds-gen -s src:11111 -d localhost:31337 -i 1
