UDP组播测试对于局域网内数据链路测试十分必要轻量化和易用性是首要考虑的问题使用mping作为UDP组播测试工具能够非常方便的进行linux、Windows等平台的组播测试。本文第4章还提供了基于C/C的udp_sender和udp_reciver组播源码可以在Linux下编译执行。
2.mping工具编译
GITHUBhttps://github.com/tongxinCode/mping 或使用如下链接go源码build可执行程序 CSDN:https://download.csdn.net/download/Axugo/89070577 官方给出的编译方法
# windows
SET CGO_ENABLED0
SET GOOSwindows
SET GOARCHamd64
go build -o mping.exe main.go
# linux
SET CGO_ENABLED0
SET GOOSlinux
SET GOARCHamd64
go build -o mping main.go
# linux arm
SET CGO_ENABLED0
SET GOOSlinux
SET GOARCHarm
go build -o mping main.go3.mping工具使用
以Windows为例将编译好的mping.exe拷贝至C:\Windows\System32路径下即可全局使用
3.1 参数说明
mping.exe -h可以得到如下
mping version: mping/1.8.1
Usage: ./mping [-h] [-s sendGroup] [-r receiveGroup] [-l localAddress] [-S sourceAddress] [-m message] [-i interval] [-log path]Options:-C int[number] the limit number of sending packets(-1 means no limits) (default -1)-S string[ip[:port]] must determine the peer source ip if using SSM (default 127.0.0.1:8888)-c whether to count Packet loss rate(default false)-e string[ascii,utf8,gbk] change the content of sending (default ascii)-h this help-i int[number] change the interval between package sent (unit:Nanosecond) (default 1000000000)-l string[ip[:port]] must choose your local using interface (default 127.0.0.1:8888)-log string[/tmp/] or [C:\] determine whether to log, Path e.g ./, Forbidden / (default /)-m string[string] change the content of sending (default Init Data)-p int[number] the size of payload data(0 means use 1472 Bytes payloads) (default -1)-proto stringchoose a lua script to parse udp data, function Parse(dataBytes) must be included (default *.lua)-r string[group:port] receive packet from group (default 239.255.255.255:9999)-s string[group:port] send packet to group (default 239.255.255.255:9999)-testsend and receive locally to examinate a test(default false)-timesend real time as the content to examinate(default false)-x whether to show the hex data(default false)3.1 组播播发-s
将组播信息播发至本机的19901端口
mping.exe -s 127.0.0.1:199013.1 组播播发-r
从19901端口接收播发的组播信息
mping.exe -r 224.0.0.8:199013.3 Linux下mping测试 4.Linux组播udp_sender及udp_reciver使用
