Linux环境下---测试已禁ping服务器的端口延迟
Linux下一个蛮好用的tcping工具
先用apt或者yum安装tcptraceroute bc这两个工具，然后执行
cd /usr/bin
wget http://www.vdberg.org/~richard/tcpping
chmod +x tcpping
mv tcpping tcping
实际效果如下
# tcping www.baidu.com 80
seq 0: tcp response from 119.75.216.20 [open] 28.308 ms
seq 1: tcp response from 119.75.216.20 [open] 28.580 ms
seq 2: tcp response from 119.75.216.20 [open] 28.289 ms
seq 3: tcp response from 119.75.213.61 [open] 28.500 ms
