how to decrease ssh connection timeout value [closed]

问题

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?

Thanks

回答1:

if you call ssh script you can use something like that

ssh -o ConnectTimeout=10  <hostName>

where 10 is the number of seconds

回答2:

You can learn much more by typing man ssh for OpenSSH command line options and man sshd for OpenSSH daemon options...
