Overview

Commands for file transfer by tcp

Characteristic

• Transfer files using buffer between file read / write and transfer process
• Monitor read / write speed and transfer speed every second and display them in Sparkline chart
• Network and storage performance can be measured with dummy data transmission and dummy reception functions

How to use

The main procedure is performed in the following two steps

• Listen to any port number on the receiving side
• Dial the destination port number on the sending side

Usage of listen mode

Usage:
  rcp listen [flags]
Flags:
  -h, --help                help for listen
  -l, --listenAddr string   listen address (default "0.0.0.0:1987")
  -o, --output string       output filename
Global Flags:
      --bufSize int         Buffer size (default 10485760)
      --dummyInput string   dummy input mode data size (ex: 100MB, 4K, 10g)
      --dummyOutput         dummy output mode
      --maxBufNum int       Maximum number of buffers (default 100)

Usage of send mode

Usage:
  rcp send [flags]
Flags:
  -d, --dialAddr string   dial address (ex: "198.51.100.1:1987" )
  -h, --help              help for send
  -i, --input string      input filename
Global Flags:
      --bufSize int         Buffer size (default 10485760)
      --dummyInput string   dummy input mode data size (ex: 100MB, 4K, 10g)
      --dummyOutput         dummy output mode
      --maxBufNum int       Maximum number of buffers (default 100)

Example of use

When listening on 1987 port on the receiving side (IP: 10.10.10.10) and sending

• Listen on TCP 1987 port on the receiving side

$ rcp listen -l: 1987 -o save_filename

• Send file to 10.10.10.10: 1987

$ rcp send -d 10.10.10.10:1987 -i input_filename

Dummy data transmission-> Discard received dummy data

• Receiver

  $ rcp listen -l: 1987 --dummyOutput

• Sender

  $ rcp send -d 10.10.10.10:1987 -i input_filename
