I am involved in a FTP to SFTP migration and have chosen Net::SFTP::Foreign as the Perl module to use to accomplish this. I have successfully modified all Perl scripts to this effect. Now another curve ball has been thrown my way ... now SSH2 (RSA) public key authentication is required. I have created the key files and passed along the public key . I am trying to use "key_path". I have changed the code from 

 
%args = ( "user" => $remuser, "password" => $rempswd );
$sftp = Net::SFTP::Foreign->new( $remnode,%args, stderr_discard => 1 )
+;

for testing this to 

 
$sftp = Net::SFTP::Foreign->new( $remnode
,key_path => '/export/home/secbatch/.ssh/id_rsa'
, stderr_discard => 1);

After each call to $sftp = Net::SFTP::Foreign->new there is 

if ( $sftp->error )    {            print "Connect Failed!";
    print "\n$@"; ##if $DEBUG;    
    print "\nConnect error: " . $sftp->error . "\n";
    print "\nConnect status: " . $sftp->status . "\n";

My log files show this

Connecting to Remote System: ... Connect Failed!

Connect error: Connection to remote server is broken

Connect status: Connection lost

Here is the dir

/export/home/secbatch/.ssh>% ls -l

total 34

drwx------ 2 secbatch gsm 1024 Feb 25 14:04 .

drwxr-xr-x 75 secbatch gsm 6144 Feb 4 17:15 ..

-rw------- 1 secbatch gsm 1675 Feb 25 14:04 id_rsa

-rw-r--r-- 1 secbatch gsm 403 Feb 25 14:04 id_rsa.pub

In the META::CPAN page for Net::SFTP::Foreign there is this note ... "Note also that latest versions of Net::SFTP::Foreign support the key_path argument".

I am successful when I try from command line with sftp -v username@remote host

.

A snippet from output ...

debug1: Authentications that can continue: publickey,password,keyboard-interactive

debug1: Next authentication method: publickey

debug1: Offering RSA public key: /export/home/secbatch/.ssh/id_rsa

debug1: Server accepts key: pkalg ssh-rsa blen 279

debug1: read PEM private key done: type RSA

debug1: Authentication succeeded (publickey).

Any guidance would be greatly appreciated.
