简单网络管理语言(Simple Network Management Language)是一种类自然语言的脚本语言，它采用snmp、telnet、ping、dns、arp、ssh、tcp、udp、web等协议访问网络设备，内置smtp协议用于告警等邮件的发送，支持excel、mysql、sqlite等3种方式进行网管数据的存取。

简单网络管理语言（snml）支持CLI（命令行接口）和SNMP（简单网络管理协议）两种方式自动化的进行网络设备配置和管理。CLI 是基于telnet、ssh的人机交互界面，用于设备的参数配置和状态的查看。SNMP 是基于通讯协议的管理工具,实现网络设备参数的自动化监控和远程配置。
网络设备的配置和管理的新技术是SDN（Software Defined Netrork）。软件定义网络是2006年斯坦福大学提出的网络设备分层编程控制系统，全新的网络设备自动化配置和管理体系。

第15章、ssh
SSH 为 Secure Shell 的缩写，可以代替Telnet的安全协议。telnet是不安全的，在网络上用明文传送口令和数据，安全验证方式容易受到“中间人”（man-in-the-middle）的攻击。
1、ssh语句分析
ssh.connect ip {192.168.186.132} port {22} username {cisco} password {cisco}
登录远程设备，设备的IPV4地址为：192.168.186.132，服务端口号为：22，用户名“cisco”密码“cisco”
ssh.connect ip {FE80::1} port {22} username {cisco} password {cisco}
登录远程设备，设备的IPV6 地址为：[FE80::1]，服务端口号为：22，用户名“cisco”密码“cisco”
ssh.set onrecv {-More-} send { %0a}
设置ssh自动输入选项，当接收到“-More-”时，自动发送一个空格和换行符
ssh.recv expect {Version}
接收服务器发送的文本，一直接收到指定字符串“Version”
ssh.recv for {3} seconds
接收3秒钟内服务器发送的文本，当服务器发送的文本中含有“-More-”时，自动发送一个空格和换行符
ssh.send {show version%0a}
发送字符串“show version”命令和换行键。
ssh.send text
发送选中的文本区域
ssh.close
关闭ssh连接。
