Expect-Scripts-to-manage-network-devices

These are simple code to manage device of network.

———————————————————————————————————————————————

The frist script is designed to backup network devices automatically.

#!/usr/bin/expect                           #解释器

set ip 192.168.70.2                         #这个脚本只设置了台机器的IP地址

set timeout 1

set username cisco

set password cisco

set timeout 3            
match_max 1000                              #这个也是必须的

spawn telnet $ip                            #进行 Telnet 操作

expect ":"

send "$username\n"                          #有个回车确认

expect "Password:"

send "$password\n"

expect "*>"

send "en\n"

expect "Password:"

send "$password\n"

expect "*#"

expect "*#"

send  "show run\n" 

send "\ \ \ \ \ \ \ \ \ \  "                #如果出现要输出空格的交互，那么在代码中设置： "\ "   要使用转义字符对空格进行转义。

log_file router.log.$ip.test                #将输出导入到 router.log.$ip.test中，这个文件会根据ip不同而保存的文件名不一样。

send "exit\n"                               #退出

expect eof                                  #结束此次的备份

↓This is the second scripts:

#the file name "telnet.test"#

#!/usr/bin/expect       
set ip [lindex $argv 0]                    #设置 IP 变量
set timeout 1       
set username cisco      
set password cisco      
set timeout 3            
match_max 1000            
spawn telnet $ip   	  
expect ":"
send "$username\n"
expect "Password:"
send "$password\n"
expect "*>"
send "en\n"
expect "Password:"
send "$password\n"
expect "*#"
send "terminal length 0\n"                  #对交换机输出结果一次性显示完！        
expect "*#"     
send  "show run\n"      
log_file router.log.$ip.test                #保存的配置的文件名，目录如果没有配置的话，默认是跟脚本在同一个文件夹中。       
send "terminal length 48\n"                 #对交换机的输出一次性只显示48行！      
send "exit\n"       
expect eof

↓这是一个循环，对多台设备进行备份：

#the file name "loop.sh"#

#!/bin/bash     
while read ip                               #循环执行 telnet.test 这个脚本      
do      
./telnet.test $ip       
done < ip.txt                               #将ip.txt中的ip地址作为变量进行导入

↓这是要备份的设备的列表：

#file name "ip.txt"#

192.168.1.1     
192.168.1.2     
192.168.1.3     
...

最后只要执行 ./loop.sh 即可！
