Shell脚本成功登录telnet，之后如何发出命令? [英] Shell script successful telnet login, how to issue commands after that?

问题描述

#!/usr/bin/expect -f
spawn telnet 10.21.0.17
expect -re "login"
send "admin\n"
expect -re "Password"
send "supersecurepassword\n"
interact

按预期工作.运行脚本后，我登录到在行spawn telnet 10.21.0.17

works as expected. Upon running the script I am logged in to whatever telent IP I used in the line spawn telnet 10.21.0.17

然后它将我带到AP的外壳

Then it drops me to the Shell of the AP

WAP->

WAP->

如何发出其他命令?我想先发布reboot，然后再发布sleep 20，最后是exit.

How do I issue further commands? I'd like to issue reboot and then maybe a sleep 20 and finally exit.

我尝试使用echo和expect失败.我还尝试了删除interact的操作，但没有成功.有什么想法吗?

I have tried using echo and expect with no success. I've also tried with removing the interact with no success. Any ideas?

推荐答案

这可以通过在expect之前添加一个sleep来解决，当然

This was resolved by simply adding a sleep before the expect, and of course not including interact, the following works well:

#!/usr/bin/expect -f
spawn telnet 10.21.0.17
expect -re "login"
send "admin\n"
expect -re "Password"
send "supersecurepassword\n"
sleep 5
expect "WAP"
send "reboot\n"
send "exit\n"

作为参考，这用于在D-Link DAP-2590无线接入点上自动重启.现在，我已经知道了这一点，我可以将其用于其他用途:更改密码等.希望将来对其他人有所帮助.

For reference, this was used to automate a reboot on a D-Link DAP-2590 wireless access point. Now that I know this though, I may use it for other things: changing passwords, etc. Hope it helps someone else in the future.
