一、Shell实现，文件名：autotelnet.sh，代码如下：


(sleep 1;echo "root";sleep 1;echo "123456";sleep 1;echo "en";sleep 1;echo "1qazse4";sleep 1;echo "conf t";sleep 1;echo "int fa0/1";sleep 1;echo "switchport mode multi";sleep 1;echo "end";sleep 1;echo "exit") | telnet 10.32.17.10


二、Expect来实现，文件名：autotelnet.exp，代码如下：


#!/usr/bin/expect


set timeout 100

set TERM xterm

set SERVER "10.32.17.10"

set USER "root"

set PASSWD "123456"


spawn telnet

expect "telnet> "

send "open $SERVERr"

expect "Username:"

send "$USERr"

expect "Password:"

send "$PASSWDr"

expect "longjiang-zero>"

send "enr"

expect "Password:"

send "$PASSWDr"

expect "longjiang-zero#"

send "conf tr"

expect "longjiang-zero(config)#"

send "int fa0/1r"

expect "longjiang-zero(config-if)#"

send "switchport mode multir"

expect "longjiang-zero(config-if)#"

send "endr"

expect "longjiang-zero#"

send "exitr"

三、Python来实现，文件名：autotelnet.py，代码如下：


#!/usr/bin/python


import telnetlib


host = ''10.32.17.10''

user = ''root''

password = ''123456''

commands = [''en'',password,''conf t'',''int fa0/1'',''switchport mode multi'',''end'']


tn = telnetlib.Telnet(host)


tn.read_until("Username:")

tn.write(user + "n")

tn.read_until("Password:")

tn.write(password + "n")


for command in commands:

tn.write(command+''n'')


tn.write("exitn")


print tn.read_all()

print ''Finish!''
