发送任意IP数据包的命令行工具：SendIP
SendIP 是一个命令行工具，用于发送任意 IP 数据包。它有大量选项可用于指定 RIP、RIPng、BGP、TCP、UDP、ICMP 或者 RAW 格式的 IPv4/IPv6 包的头文件，同时，它还允许在包中加载数据。校验信息会自动进行计算，如果你想发送错误的校验信息，它也是支持的。
Install sendip on ubuntu
Open the terminal and run the following command
sudo apt-get install sendip
Using Sendip
Syntax
sendip [-v] [-d data] [-h] [-f datafile] [-p module] [module options] hostname
-d data -- add this data as a string to the end of the packet Data can be: rN to generate N random(ish) data bytes; 0x or 0X followed by hex digits; 0 followed by octal digits; any other stream of bytes
-f datafile -- read packet data from file
-h -- print this message
-p module -- load the specified module (see below)
-v -- be verbose
Available modules at the moment as follows
