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
001	screen.text at point {150} {30} string {15. ssh (ipv4) Test, (use ssh you need to get ssh.key License File)}
002	var {v_y} value {60}
003	screen.text at point {10} {~v_y~} string {No. server ip:port send command recv }
004
005	screen.line from point {10} {75} to point {30} {75}
006	screen.line from point {50} {75} to point {270} {75}
007	screen.line from point {300} {75} to point {630} {75}
008
009	screen.text at point {10} {425} string {1. run ssh_req.bat 2. send email with file ssh_req.txt%0d%0a}
010	screen.text at point {10} {450} string {email1: ladybird_snml@protonmail.com, email2: ladybird_snml@hotmail.com%0d%0a}
011
012	var {v_time} value datetime
013	var {v_i} value {0}
014	run.set loglevel {debug}
015	loop.begin
016
017	var {v_i} add number {1}
018	var {v_y} add number {18}
019
020	ssh.connect ip {192.168.186.132} port {22} username {cisco} password {cisco}
021	ssh.set onrecv {-More-} send { %0a}
022	ssh.recv for {3} seconds
023	ssh.send {show version%0a}
024	ssh.recv expect {Version}
025	ssh.recv for {3} seconds
026	ssh.close
027	text.headpointer move to head
028	text.tailpointer move to tail
029	text.save append to file {C:\snmlipv6\ssh\ssh_out_ipv4~v_i~.txt}
030	screen.text at point {10} {~v_y~} string {~v_i~}
031	screen.text at point {50} {~v_y~} string {192.168.186.132:22 send 'show version'}
032	screen.text at point {300} {~v_y~} string {ssh.recv : ~text.bytes~ Bytes }
033	text.delete from headpointer
034
035	if.var {v_y} > {100}
036	loop.exit
037	if.end
038	loop.end
039	run.end
