Re: [JSch-users] How to upload/download files from MVS system.

[Oberhuber, M. <Mar...@wi...>]

Hi Brij,
=20
you are misunderstanding. SFTP is _not_ just a secured version of FTP, =
it is something different.
=20
I see two alternatives for you:
=20
a) Get an ssh server for MVS that supports standard sftp (not sure if =
such a server exists).
=20
b) Instead of SFTP, use FTP-over-ssh. It works like this:
    * ssh does port forwarding of port #21 through its secure connection
    * you use a standard FTP client to access the standard MVS FTP =
server - but through the forwarded port

When I remember right, you were writing your own Java FTP client -- =
adding jsch port forwarding to that
client should be easy to do.

Cheers,
Martin

	Hi,
	Thanks for reply.
=09
	If SFTP protocol does not support 'SITE' command then how can we =
upload/download files from MVS system?. I thought SFTP provides all =
functionality of FTP protocol but additionaly provides secured =
communication.
=09
	While FTP we send some file parameters via SITE commands. These site =
parameters may be 'quote SITE sbd=3D.........' or 'cylinders pri=3D1 =
sec=3D1'. These types of parameters, we were passing  using SITE =
commands in case of simple FTP. I think these parameters are specific to =
MVS system & without these parameters we can not upload/download files =
from MVS system.
=09
	For simple FTP we were using jakarta's commons.net API's methods =
FTPClient.sendSiteParameters().=20
=09
	But if I want to upload/download files from MVS thru SFTP then how can =
I achieve this task. Since SFTP is secured version of FTP so there =
should be some workaround to achieve such task. Please let me know how =
can I achieve this task?.
=09
	Thanks & Rregards

for SFTP. Which method of JSch API can be used for it & how? OR which =
command of SFTP is equivalent to it & which is corresponding method in =
JSch API?

		On the sftp protocol, SITE command is not defined, unfortunately.
