自动登录telnet批处理文件

自动登录telnet批处理文件 
一。Windows平台：
复制一下代码到记事本中并另保存为autoTelnet.bat，之后双击运行就实现自动登录到telnet服务器了，服务器IP自己修改
@echo off
echo set sh=WScript.CreateObject("WScript.Shell") >telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys "open 192.168.1.200" >>telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys "{ENTER}" >>telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys "engineer{ENTER}" >>telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys "ls {ENTER}">>telnet_tmp.vbs
start telnet
cscript //nologo telnet_tmp.vbs
del telnet_tmp.vbs

二。Linux平台

保证你的系统上存在expect这个可执行程序，保存以下代码到文件autoTelnet，并给与执行权限。详细操作察看命令expect

#!/usr/bin/expect --
set SERVER "192.168.1"
set USER "myusername"
set PASSWD "mypass"
if { $argc } {
spawn telnet $SERVER.$argv
} else {
spawn telnet $SERVER.200
}
expect "Password:"
send "$PASSWD\n"
expect "#"
send "ls\n"
