I have two nodes that are set up with mutual RSA keys. I can SSH and SFTP freely between them, bilaterally, password-less.I can also SFTP between then with Perl Net::SFTP using host and user and pass.

Now I want to add Foreign, and transmit between them without a password. I'm currently trying: 

my $ftph;
eval {
 $ftph = Net::SFTP::Foreign( "$user\@$host", more=>'-v', autodie=>0 );
};

[download]
after this step, $ftph is undef, and $! = 'Inappropriate ioctl for device'. And of course $ftph->error is undef as well.

If I try sftp user@host at the commandline, the SFTP connection is made successfully with no password, and it drops to the SFTP> prompt.

All of the examples I can find using ::Foreign , as well as the metacpan page, pretty much just start with this same expression, more or less. But I wonder, am I suppposed to establish an SSH pipe first with Perl BEFORE this step, but the examples don't show that step? I did see some examples that had use IO::Pty; , but there was no further calls to that class before the Net::SFTP::Foreign line.

Without the eval {} , the step dies with no message at all.

I also added $Net::SFTP::Foreign::debug = -1; but it didn't seem to produce any additional output.

Advice, tips, and guidance are most appreciated.
