expect不能自動登錄

expect {
    "(yes/no)?" {
        send "yes\n"
        expect("Password:*"){
             send "AiAw#145\n"
       }
}
        "Password:*" {
        send "AiAw#145\n" 是密碼#的問題，有那么大俠能告知#號，在expect中的轉(zhuǎn)義字符是多少。謝謝。

    }
}

#expect eof           

執(zhí)行的結(jié)果是這樣的:

david6102

expect {
        "No route" { exit }
        "want" {send -- "yes\r"; exp_continue}
        "password:" {send -- "密碼\r"}
        }

我試過這樣是沒問題的，不然你也試試？

回復(fù) 2# david6102


    還是不行。還是到password就停了。

沒好好看教程吧
需要一個(gè)while 循環(huán)
要不他只運(yùn)行一次

flyinsky191

回復(fù) 4# nuclearxin


    如果手工運(yùn)行ssh Aiinweb@137.32.44.145也只需要輸入一次密碼就可以了 。為什么要用while循環(huán)。每次都是到password之后就跳了出來。

#!/usr/local/bin/expect

我是這樣寫的�？墒且恢碧崾綪assword，多輸入幾次密碼之后就成這樣了
spawn ssh -p22 Aiinweb@137.32.44.145
Password:
Password:
Password:
Aiinweb@137.32.44.145's password:
Permission denied, please try again.

expect 用起來確實(shí)有點(diǎn)別扭.... 不過在python 中  pexpect 的模塊做的比較好,,, 有機(jī)會可以去嘗試下 至于shell 下的

spawn ssh $IP $CMD
expect  {
    "*continue connecting (yes/no)?*"
    {
    send "yes\r"
    exp_continue
    }
    "*password*"
    {
    send "$PWD\r"
    exp_continue
    }
    "*Last login*"
     {
    interact
    exit 0
    }
    eof
    {
    exit 1
    }
僅供參考......

我的腳本是：
#!/usr/local/bin/expect -d

spawn ssh -p22 Aiinweb@137.32.44.145
expect "*?assword:*"
send "AiAw#145\r"

interact
