Re: [Ssh-sftp-perl-users] Fwd: How to load my private DSA key for authentication?

[Steve P. <st...@fo...>]

This is putty telling you that it doesn't know about this host as the 
host key isn't in puttys cache.

You can add this by using putty manually to connect to the host and 
telling it to save the key in its cache.

The reason the script fails is it (putty) is asking for an interactive 
response but, being a script there is no way to get this and so it exits.
