How to reduce ssh connection timeout value

Question

I have a list of the full IP addresses of the remote host. I wrote a script to connect all the hosts in this list one by one. My question is that sometimes, when the IP address is not working, the script waits for a while (maybe a couple of minutes) to go ahead and execute the next node. Therefore, I would like to reduce this waiting time. For example, after 10 seconds, I want the ssh connection to timeout, and my script tried the following IP address. So how can I customize this?

thanks

Answer 1

if you call ssh script you can use something like this

ssh -o ConnectTimeout=10 <hostName> 

where 10 is the number of seconds

Answer 2

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