Question

我有以下代码：

#!/usr/bin/expect
set timeout 20
set port "23"
set user "admin"
set password "1234"
set ip_file "devices"
set fid [open $ip_file r]
while {[gets $fid ip] != -1} {
spawn telnet $ip $port
expect "'^]'." sleep .1;
send "\r";
sleep .1;
expect   "login:"
send "$user\r"
expect "Password:"
send "$password\r"
expect "#\r"
send "conf\r"
send "username root privilege 15 password toor\r"
send "no username admin\r"
send "end\r"
send "wr\r"
send "y\r"
send "exit\r"
expect eof

}
close $fid

如果密码不正确，我需要知道如何从“设备”跳到下一个IP。还要在执行脚本的本地文件上写入密码不正确的设备的IP。

谢谢！

好的，在这里您可以更高级地使用expect命令：您向它传递了一个模式/动作对的 list ：未经测试

expect "Password:"
send "$password\r"
expect {
    "login:" {
        # bad password: hit Ctrl-C and move on to the next IP
        send \x03
        expect eof
        continue
    }
    "#\r"
}
# we've seen the prompt so you can carry on with the rest of your script

在这种情况下，expect将根据其可以找到的 first 模式进行分支。

期望脚本跳过错误的密码
