This is a ping tool using TCP. This tool consists of two executable, the client and the server.

This project is a homework of NTU CSIE Computer Networks, Fall 2019.

• Can ping mutiple target simultaneously. (Implemented using std::thread)
• Colored output.
• Simple ping statistics.

These instructions will get you a copy of the tool up and running.

• g++
• Boost C++ Libraries (Or more specific, the libboost-program-options-dev package)
• GNU Make

This tool can only run on linux.

1. Get the source code of this tool. Maybe clone from GitHub. Skip this step if you already got the source code.

2. run make at the project root (at the same folder where this README.md file is).

If nothing goes wrong, you now get both the client and the server executable.

Usage of the server:

Usage: ./server [--help] port

Positional Argument
  port - Port to listen on

Optional Arguments
  -h [ --help ]         Print help messages

The server should be started before the client.

Usage of the client:

Usage: ./client [--help] [-n num] [-t timeout] [-w wait] target1 [target2 ...]

Positional Argument
  target - Target(s) in `host:port` form, host can be in hostname or ip

Optional Arguments
  -h [ --help ]                Print help messages
  -n [ --num ] arg (=0)        Amount of packets to send to each target, 0
                               means keep sending messages until program close
  -t [ --timeout ] arg (=1000) Maximum millisecond(s) the client needs to wait
                               for each response
  -w [ --wait ] arg (=1000)    Millisecond(s) the client need to wait between
                               each ping
