Hello,
I don't know, if this is the forum to raise a question about the openSSH and a
communication problem that we have using the "sftp" to a SFTP Root Gateway
Server. Here below you got the explanation of our problem:
We would like to communicate a LINUX and/or UNIX platform to a NT Server
(automatically) in a secure way: Sending files from a UNIX/Linux platform to NT
Servers. For security restrictions, etc is not possible to use Samba and there
is only allowed the use of a secure file transfers (sftp).
Specifications:
a) UNIX BOX based in Solaris 2.6 and using: OpenSSH_3.8.1p1, OpenSSL 0.9.6m 17
Mar 2004 or
Linux Box (OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090607f)
b) NT Server is accessible through a NT Gateway with a SFTP Root based in a (
VShell Secure Shell server).
Communication should be (per specs): UNIX/LINUX -> GatewayNT Serverwith
the SFTP Root Software -> RemoteNTServer
To ways:
a) With an authentication using public keys. See note at the end of this
email
b) Using the "sftp" from Linux/UNIX to the NT Gateway. The reason we want
to use this method is because the Gateway NT Server; using the sftp and
providing the password allow us to access to specific share resources in NT
(needs authentication).
Problem:
Everything works fine using from UNIX the "sftp" Se example below:
sftp user@gatewayNTserver
Connecting to gatrewayntserver...
Unauthorised Access Warning:
Access to this computer is prohibited unless authorised.
Accessing programs or data unrelated to your job is
prohibited.user@gatentwayserver's password:
Enter the password when prompted.
but the password for the "user" is required/mandatory. Is there anyway to
included the password automatically in the "sftp" statement? Like:
sftp user:password@gatewayNTServer?
We need to include the "sftp statement inside a unix/linux script (ksh) as part
of a batch process and it's not possible to implement a solution using the
"sftp" because we can not find out a solution to provide the password
automatically. is there any way to do this? I have seen some similar solution
with VANDYKE Software like: (This is not the same but includes in a sftp the
user and password together.
Download from remote host:
SFXCL sftp://[<user>[:<password>]@]<host address>[:<port>]/<source
path> <destination path>
Upload to remote host:
SFXCL <source path> sftp://[<user>[:<password>]@]<host
address>[:<port>]/<destination path>
Note:
Using Public Key Only authentication instead of password authentication will
only grant access to the HOST only (\\REMOTENTSERVER\SHARE$). In order to
access a remote share on another server the username/password must be supplied
as this is required to authenticate to the remote NT file system. It's
possible to configure the gateway to use the public key from the Unix host BUT
as we need to transfer files to the remote host \\RemoteNTServer\resource$ we
will need to supply a password.
Let me know if it's not well explained but the question is How we can include
the password automatically in the "sftp" (OpenSSH). We don't see any version of
the OpenSSH with this option.
Thanks!
