一：安装ICMP SHELL
首先下载ish-v0.2.tar.gz程序，下载地址：http://cdnetworks-kr-1.dl.sourceforge.net/project/icmpshell/ish/v0.2/ish-v0.2.tar.gz，或者可以到附件中去下载。
- wget http://cdnetworks-kr-1.dl.sourceforge.net/project/icmpshell/ish/v0.2/ish-v0.2.tar.gz
- tar zxvf ish-v0.2.tar.gz
- cd ISHELL-v0.2/
- make linux
第四步可根据自己是实际情况而定，你可以先执行make命令，然后它会给你提示：
我这里是redhat系统，所以make linux。
好了，现在就安装好了，简单吧。
