I have a problem with my script. It seems my password is wrong.

#!/usr/bin/expect

set ip [lindex $argv 0]
spawn telnet $ip
set timeout 10
expect "Login:"
send "administrator\r"
expect "Password:"
send "123456"
send "\r"

It says, login incorrect. But it works, when i use cmd on Windows to telnet to my phone, it works with "administrator" and 123456 as password. I don't know why in my script, I could not log on successfully.

I have to use this script to downgrade/upgrade my phones.

  • Your directive /usr/bin/expecct has an extra c in it. That might not be causing the issue, but could you correct it and try? – rahul Feb 13 '15 at 11:15
  • Also, take a look at this link - bash.cyberciti.biz/security/expect-ssh-login-script. The password could be in uppercase or lower case. Try this and see if it helps. – rahul Feb 13 '15 at 11:16
  • My password is only numbers :/ And sorry for the expecct, my bad, in my script it's expect. – Xiuur Feb 13 '15 at 11:20
  • You haven't send \r after your password, plus you have a send with /r instead \r – YoMismo Feb 13 '15 at 11:21
  • What i meant was the prompt could be either "Password:" or "password", can you try replacing the expect "Password:" with expect "?assword:" – rahul Feb 13 '15 at 11:22

I found the answer. I just have to put some

sleep

command before

expect "Login:"

Thanks to all.
