tcping 安装和使用

简述

网络延迟用的最多的是基于icmp协议的ping，但是对于一些禁止ping的服务端将不起作用，这个时候如果我们想要测试网络延迟那么可以使用tcping工具；此工具的原理和他的名字一样是基于tcp协议的，通过tcp的三次握手实现；

安装

Centos：

yum install tcptraceroute bc -y
wget -O tcping https://soft.mengclaw.com/Bash/TCP-PING
chmod +x tcping
mv tcping /usr/bin

Windows:
windows的tcping和linux下的不是同一个软件，但是基础的使用方式差不多，具体看下帮助信息，下载地址如下：

使用

[root@192.168.128.129 ~]# ./tcping
tcpping v1.7 Richard van den Berg <richard@vdberg.org>

Usage: tcping [-d] [-c] [-C] [-w sec] [-q num] [-x count] ipaddress [port]

        -d   print timestamp before every result
        -c   print a columned result line
        -C   print in the same format as fping's -C option
        -w   wait time in seconds (defaults to 3)
        -r   repeat every n seconds (defaults to 1)
        -x   repeat n times (defaults to unlimited)
