Question

I want to be able to issue a command like the following:

ssh mark

Given that mark is a host configured in the ssh_config file like this:

host mark
    hostname 192.168.0.10 
    user root

This works ok given that I’ve copied my public key to that station.
What I want is to be able to configure multiple ip addresses in the hostname field in case one of marks’s interfaces goes offline.
I would like something like:

hostname 192.168.0.10,192.168.0.11

Answer 1

You should add single host name and let your domain name server returns multiple IP addresses (hint check CNAME).
