/rping

Primary LanguageRust

rping

simple ping program written for homework assignment, under development.

Usage

use the build.sh script:

./build.sh www.example.com

or manually:

cargo build --release
sudo setcap cap_net_raw=+eip $(PATH_TO_PROGRAM)
cargo run --release -- www.example.com

examples

./build.sh --help
./build.sh -c 3 127.0.0.1
./build.sh ::1

problems

  • -b flag:

when pinging 255.255.255.255, program panics without usefull information.

trying sudo instead of setcap have the same result.

no relative information found on the internet.

  • thread::sleep stuck \C-c

  • slower than ping program:

while running

ping www.example.com -c 5

ping gives 4000ms execution time, while our program gives 5000ms.

TODO

  • send and receive packet
  • echo output message to STDOUT
  • make ping and echo concurrent
  • calculate statistics after \C-c
  • colorful output message, maybe use crate colored
  • args
    • support ip address
    • support hostname
    • -b 允许ping一个广播地址，只用于IPv4
    • -c 数目 在发送指定数日的包后停止
    • -h 显示帮助信息
    • -i 设定间隔几秒发送一个包给指定机器
    • -q 安静模式，不显示每个收到的包的分析结果，只在结束时，显示汇总结果
    • -s 指定发送的数据字节数
    • -t 设置ttl值，只用于IPv
