Question on openSSH and sending file to MVS file formats Remove Highlighting

--------------------------------------------------------

Hello,

I was looking for Damien Miller, Markus Friedl or Theo de Raadt to
possibly answer an SFTP question. I am having trouble locating an example
and think the task can not be done.

Do you have an example of an unix host machine initiating a file transfer
to an ibm z/OS and create a mvs file?

I have examples from appendix A of the IBM Ported Tools for z?OS Users
Guide that shows how from IBM jcl initiated, I shell down using the !cp
command to pull it in to z/OS unix, then sFTP to the external unix
machine. That works ok. I can also run an IBM mvs job and pull a file
from my Tokyo site and create a MVS file, but it is running the program on
the IBM side.

If my client's unix Sun box in Tokyo connects to my chicago ibm
mainframe, what sFTP commands to I use to create a MVS file?

This perhaps?

put john_sftp_test.txt "//'TEST.JOHN.SFTP.TEXT'"
quit

Or perhaps I need to have a file watcher running on ibm z/Os unix to run a
program to complete the transfer.

Thank you for your assistance.


Regards,

I'm afraid the only ones who can help with this would be those who
know how the implementation on z/OS was done. I guess that is IBM.

I suggest starting with trying to downloading files from your IBM
machine, even though this is not what you ultimately want to do.
It might provide more helpful error messages or hints that will
help understanding the required filename syntax.

Oh, and are you absolutely sure that the IBM machine actually is able
to act as an SFTP server? This may not be the case.

Does this work? Then you're all set.

One option is certainly to always initiate the transfer from the IBM
machine, since you've found a working method for that. You would have
to set up a staging server which both tokyoclient and youribm can log
in to via SFTP. It could run some common Linux or other well-known
system.


Hope this helps.
