passwordless ssh from laptop

[thufir]

To disable password authentication, look for the following line in your 
sshd_config file:

#PasswordAuthentication yes


in:

/etc/ssh/sshd_config


this change is made in the target machine not the laptop I'm sitting at?  

The laptop I connect from usually, but not always, has the same IP 
address.  It has a registered FQDN which, in a pinch, I could update 
through www.noip.com when at a cafe.  Would that be a problem?



thanks,

Thufir
