在 shell 脚本中远程登录 [英] Telnet inside a shell script

问题描述

如何在 shell 脚本中运行 telnet 并在远程服务器上执行命令?

How can I run telnet inside a shell script and execute commands on the remote server?

由于安全原因，我没有在我的solaris机器上安装expect.我也没有安装 perl net::telnet 模块.

I do not have expect installed on my solaris machine because of security reasons. I also do not have the perl net::telnet module installed.

如果不使用 expect 和 perl，我该怎么做?

So with out using expect and perl how can I do it?

我尝试了下面的方法，但它不起作用.

I tried the below thing but its not working.

#!/usr/bin/sh
telnet 172.16.69.116 <<!
user
password
ls
exit
!

当我执行它时，这就是我得到的:

When I execute it, this is what I am getting:

> cat tel.sh
telnet 172.16.69.116 <<EOF
xxxxxx
xxxxxxxxx
ls
exit
EOF
> tel.sh
Trying 172.16.69.116...

推荐答案

您的某些命令可能会被丢弃.您可以使用普通的脚本结构实现更精细的控制，然后通过带有 echo 的管道发送所需的命令.将命令列表分组以创建一个会话":-

Some of your commands might be discarded. You can achieve finer control with ordinary script constructs and then send required commands through a pipe with echo. Group the list of commands to make one "session":-

{
sleep 5
echo user
sleep 3
echo password
sleep 3
echo ls
sleep 5
echo exit
} | telnet 172.16.65.209
