I have a Windows machine attempting to start an sftp session with a
Linux OpenSSH host. I have Net::SSH::SFTP, Net::SSH::W32Perl and
required modules installed.

I get the following debug output:

dcasrv8: Connecting to ****.*********.com, port 22.
dcasrv8: Socket created, turning on blocking...
dcasrv8: Remote protocol version 2.0, remote software version
OpenSSH_3.7p1
dcasrv8: Net::SSH::Perl Version 1.25, protocol version 2.0.
dcasrv8: No compat match: OpenSSH_3.7p1.
dcasrv8: Connection established.

The snippet of code that makes the call is this:

$sftp = Net::SFTP->new($SSH_HOST, user=>$SSH_USER,
password=>$SSH_PWD, debug=>1, ssh_args=> [protocol=>2, port=>$SSH_PORT,
use_pty=>0]);

Does the use_pty parameter control requests for a shell?

The host is accessible (and drops into an sftp shell!) from the same
machine using the same creds with an sftp client.

Any ideas?

TIA,
