based on question key based authenication net-sftp in ruby, can sftp key-based authentication using following:
net::sftp.start(host, "user", keys:['~/.ssh/my_key']) |sftp| sftp.upload! "/local/file.tgz", "/remote/file.tgz" end but can't work keys require passphrase -- prompted user login on host. missing pass in let me enter passphrase key? or need stick ssh-agent this?
there's passphrase option:
the passphrase use when loading private key (default
nil, no passphrase)
if not specify passphrase, should asked one, unless used non_interactive option:
set true if app non interactive , prefers authentication failure vs password prompt
non interactive applications should set true prefer failing password/etc auth methods vs asking password
