tcping
======

一个类似于 ping 的系统工具， 检测在连接 tcp 时候的延迟，
比较正确是反应出网络的延迟情况，毕竟 tcp 用途比较广。

虽然和 icmp 的 ping 原理不同，ping 命令也能很大程度上反映出网络的延迟，
但是该矫情还是要矫情一把的。

Usage

::

    pip install tcping

    Connected to api.github.com[:80]: seq=9 time=248.26 ms
    Connected to api.github.com[:80]: seq=10 time=251.77 ms

    --- api.github.com[:80] tcping statistics ---
    10 connections, 10 successed, 0 failed, 100.00% success rate
    minimum = 233.51ms, maximum = 251.77ms, average = 243.40ms

呵呵，GFW，66666

::

    ➜  ~ tcping --help
    Usage: tcping [OPTIONS] HOST

    Options:
      -p, --port INTEGER      Tcp port
      -c, --count INTEGER     Try connections counts
      -t, --timeout FLOAT     Timeout seconds
      --report / --no-report  Show report to replace statistics
      --help  

其中这个 ``--report`` 可以生成一个 ascii 的 table，好看一点吧。。。

::

    ➜  ~ tcping api.github.com -c 3 --report
    Connected to api.github.com[:80]: seq=1 time=237.79 ms
    Connected to api.github.com[:80]: seq=2 time=237.72 ms
    Connected to api.github.com[:80]: seq=3 time=258.53 ms

其实写这个主要是为了测试搭建翻墙 VPS 的 tcp 延迟。。。
