làm thế nào để sử dụng Net :: SSH :: Perl với khóa công khai?

Question

Tôi đang cố gắng sử dụng Net::SSH::Perl để kết nối sử dụng khóa công khai với mã này:

my $ssh = Net::SSH::Perl->new($host, debug=>1) || die ...... 

tôi đặt chìa khóa trong /root/.ssh/id_rsa và /root/.ssh/identity

Nó có vẻ như nó không cố gắng sử dụng khóa công khai và thay vào đó cố gắng để yêu cầu một mật khẩu:

tôi nhận được kết quả này:

tìm thấy nó: ha ve để chỉ định vị trí tệp khóa theo cách thủ công:

@KEYFILE = ("/root/.ssh/id_rsa"); 
$ssh = Net::SSH::Perl->new($host, debug=>1, identity_files=>\@KEYFILE)
