expect ssh 自动输入登入密码错误，就一直卡在输入密码里没反应

515863429

#!/usr/bin/expect -f
set host [lindex $argv 0]
set pwd  [lindex $argv 1]
#set cmd  [lindex $argv 2]
set timeout -1
#log_user 0
spawn ssh -t $host
expect {

                    "*yes/no*" {send "yes\r";exp_continue}

                    "*assword*" {send  "$pwd\r";exp_continue}

        }
expect "*$*"
send "sudo su -\r"
expect "*#*"
send "hostname\r"
#log_user 1
expect "*#*"
send "exit\r"
log_user 0
expect "*$*"
send "exit\r"
log_user 0
expect eof


我想实现密码错误能自动输入三次后往下走，或者直接跳过也行，求帮忙。
一直卡在
spawn ssh -t xx.xx.xx.xx sudo cat /etc/shadow
aiuap@xx.xx.xx.xx's password:
Permission denied, please try again.
aiuap@xx.xx.xx.xx's password:

没人帮忙么

自己手工跑一遍...

root@127.0.0.1's password:
Permission denied, please try again.
root@127.0.0.1's password:
Permission denied, please try again.
root@127.0.0.1's password:
Permission denied (publickey,password).

pzghost

sshpass不是更好用，或ssh-copy-id公钥登录。

后面的命令是接sudo 按上面的运行后得出以下结果
spawn ssh -t 127.0.0.1
aiuap@127.0.0.1's password:
Permission denied, please try again.
aiuap@127.0.0.1's password:
Permission denied, please try again.
aiuap@127.0.0.1's password:
Permission denied (publickey,password,keyboard-interactive).
expect: spawn id exp4 not open
    while executing
"expect "*$*"   "

有帖子写过遇到这样的情况，但是我运行还是识别不到
spawn ssh  10.10.10.1
           expect {
                      "\[#$\]"     {send "\r" }   ### 假如有了ssh 公钥之类的，直接回车。当然普通用户下边还可能需要sudo,自己处理一下吧。
                    "not know" {send_user "[exec echo \"not know\"]";exit}

                    "(yes/no)?" {send "yes\r";exp_continue} #continue的意义，靠猜测也能差不多知道了吧？可以Man expect

                    "password:" {send  "$pwd\r"}

                    "ermission denied, please try again." {

                        send_user "[exec echo \"Errorassword is wrong\"]"

                        exit  }

                    }
