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。

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。

2、示例脚本[C:\snmlipv6\ssh\ssh_ipv4.txt]

C:\snmlipv6\ssh\ssh_ipv4.txt

001screen.text at point {150} {30} string {15. ssh (ipv4) Test, (use ssh you need to get ssh.key License File)}
