一次远程重启多台Mac

Question

我们有一个由9台Mac组成的网络，我想一下子把它们全部关闭。现在我正在使用这个AppleScript，但正如您所看到的，它使用SSH逐个关闭计算机。如果其中一个已经关闭，脚本将会冻结。有没有办法让我一次关闭所有的Mac？

set finalIP to 100
repeat until finalIP is 109
tell application "Terminal"
    activate
    set success to 0
    do script "echo Rebooting.."
    do script "ssh -l username 192.168.1." & finalIP in front window
    delay 1
    repeat until success = 1
        if last word of (contents of front window as text) = "no" then
            do script "yes" in front window
            delay 1
        else if last word of (contents of front window as text) = "password" then
            do script "password" in front window
            set success to 1
            do script "echo About to reboot.." in front window
        else
            delay 1
        end if
    end repeat
    do script "sudo reboot" in front window
    repeat until last word of (contents of front window as text) = "password"
        delay 1
    end repeat
    do script "password" in front window
    close front window
end tell
set finalIP to finalIP + 1
delay 1
end repeat
tell application "Terminal" to quit

Answer 1

您可以简单地为ssh连接设置一个超时：

ssh -o ConnectTimeout=10 -l ...

(这是10秒超时，请根据需要进行调整。)

另外，还可以考虑使用键进行连接。确实没有充分的理由将SSH密码放在脚本中。(如果您这样做了，还要添加-o BatchMode=yes选项-它将跳过您无法使用密钥登录的主机。)

Answer 2

-o标志允许您指定一个超时时间，这样当它在指定的秒数之后没有成功连接时，它将中止。

imac$ ssh -o ConnectTimeout=5 123.45.6.7
ssh: connect to host 123.45.6.7 port 22: Operation timed out
