how to decrease ssh connection timeout value
提问by JavaRed
I have a list of full remote host ip addresses. I wrote a script to connect all the hosts in this list, one by one. My question is, sometimes when an IP address is down, script waits for a while (maybe a couple of minute) to go and execute next host. So I would like to decrease this waiting time. For example after 10 s, I want ssh connection is timeout and my script tries the next IP address. So how I can tweak this?
我有一个完整的远程主机 IP 地址列表。我写了一个脚本，将这个列表中的所有主机，一一连接起来。我的问题是，有时当 IP 地址关闭时，脚本会等待一段时间（可能几分钟）去执行下一个主机。所以我想减少这个等待时间。例如，在 10 秒后，我希望 ssh 连接超时并且我的脚本尝试下一个 IP 地址。那么我该如何调整呢？
Thanks
谢谢

if you call ssh script you can use something like that
如果你调用 ssh 脚本，你可以使用类似的东西
ssh -o ConnectTimeout=10 <hostName>
where 10 is the number of seconds
其中 10 是秒数

You can learn much more by typing man sshfor OpenSSHcommand line options and man sshdfor OpenSSHdaemon options...
您可以通过键入学到更多man ssh的OpenSSH命令行选项，并man sshd为OpenSSH守护进程选项...
