1 基础知识

一款可以使用MikroTik RouterOS MAC-Telnet协议连接MikroTik路由的telnet客户端软件。

2 最佳实践

2.1 部署Docker环境

本章使用如下Docker环境部署，参阅本章建议你先搭建以下Docker集群环境并熟悉，

如何部署Docker生产环境？

2.2 创建新镜像

2.2.1 创建镜像项目文件夹

mkdir ~/imageProject-MAC-Telnet

2.2.2 创建Dockerfile

vim ~/imageProject-MAC-Telnet/Dockerfile

加入如下配置，

FROM centos:centos7
MAINTAINER will@cmdschool.org
RUN echo https://github.com/haakonnessjoen/MAC-Telnet

# Update OS
RUN rm -rf /etc/yum.repos.d/*
RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
RUN yum update -y
RUN yum -y install wget automake autoconf gcc make

# Download fiels
WORKDIR /root/
RUN wget https://codeload.github.com/haakonnessjoen/MAC-Telnet/tar.gz/refs/tags/v0.4.4 -O MAC-Telnet-0.4.4.tar.gz
RUN tar xf MAC-Telnet-0.4.4.tar.gz
RUN ls -la

# Deploy MaC Telnet
WORKDIR /root/MAC-Telnet-0.4.4/
RUN yum -y install gettext-devel
RUN mkdir m4
RUN ./autogen.sh
RUN ./configure
RUN make
RUN make install

# Config Start Scripts
CMD ["/usr/sbin/init"]

需要注意的是，
– “FROM”指令声明基于“centos:centos7”镜像打包
– “RUN”指令声明容器环境执行的命令
– “EXPOSE ”指令声明容器使用的端口
– “WORKDIR”指令声明切换容器内部的某个目录
– “CMD”指令声明启动容器执行的启动服务命令

2.2.3 执行打包操作

cd ~/imageProject-MAC-Telnet
docker build -t build/mac-telnet:0.4.4 .

以上“.”指当前目录为编译目录，编译程序会自动加载“Dockerfile”文件定义，可见如下显示，

[...]
Removing intermediate container 7057550931db
 ---> 40b64baa8b44
Successfully built 40b64baa8b44
Successfully tagged build/mac-telnet:0.4.4

完成后，可使用如下命令查看镜像，

docker images

可见如下显示，

REPOSITORY                                      TAG       IMAGE ID       CREATED              SIZE
build/mac-telnet                                0.4.4     40b64baa8b44   About a minute ago   812MB
[...]

2.2.4 测试软件运行

docker run -it --rm --net=host --name mac-telnet build/mac-telnet:0.4.4 /bin/bash

然后，可通过以下命令测试安装，

mactelnet -h

可见如下显示，

MAC-Telnet 0.4.4
Usage: mactelnet  [-h] [-n] [-a ] [-A] [-t ] [-u ] [-p ] [-U ] | -l [-B] [-t ]

Parameters:
  MAC            MAC-Address of the RouterOS/mactelnetd device. Use mndp to
                 discover it.
  identity       The identity/name of your destination device. Uses
                 MNDP protocol to find it.
  -l             List/Search for routers nearby (MNDP). You may use -t to set timeout.
  -B             Batch mode. Use computer readable output (CSV), for use with -l.
  -n             Do not use broadcast packets. Less insecure but requires
                 root privileges.
  -a       Use specified path instead of the default: ~/.mactelnet for autologin config file.
  -A             Disable autologin feature.
  -t    Amount of seconds to wait for a response on each interface.
  -u       Specify username on command line.
  -p   Specify password on command line.
  -U       Drop privileges to this user. Used in conjunction with -n
                 for security.
  -q             Quiet mode.
  -h             This help.

测试完成后可使用如下命令退出容器虚拟机，

exit

另外，也可以这样用，

docker run -it --rm --net=host build/mac-telnet:0.4.4 macping 80:2a:a8:cc:8f:2d
docker run -it --rm --net=host build/mac-telnet:0.4.4 mactelnet 80:2a:a8:cc:8f:2d
docker run -it --rm --net=host build/mac-telnet:0.4.4 mndp 80:2a:a8:cc:8f:2d
docker run -it --rm --net=host build/mac-telnet:0.4.4 mactelnetd 80:2a:a8:cc:8f:2d
