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"

interact

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!
