sftp image xfer of vms saveset fails

VMS v9.2, tcpip x6.0-16, openssh v8.9-1B, ssl1112 v1.1-1N
sftp> image or binary
Invalid command
sftp> get file.a ! vms saveset from VSI itanium v8.4-2L1 TCPIP v5.7-13ECO5F
i hoped with no image/binary command the 9.2 port would auto-recognize the file from another vms system.
I could not find if their is a -flag for image
some tries it stack dumps, sometimes it finishes xfer 100%, but the file is not a vms saveset.
any pointers and help on what I am missing?

OpenSSH does not understand VMS file structures; it transfers everything in Stream-LF.
In order to transfer a save-set, ZIP is recommended. There's a set of ZIP/UNZIP files in subdirectory of SYS$ETC as of V92.

Code: Select all
> [...] but the file is not a vms saveset.
As usual, showing the actual command and the actual error message
might be more helpful than a vague description/interpretation.
Copy+paste is your friend.

Or, if the only problem at the destination is bad file attributes,
then it should be possible to fix them. See, for example:

the command was as i listed
sftp> get file.a
sometimes it stack dumps, sometimes it get 100% but was not a valid saveset after xfer.
i put files into zip format and it works, just an extra step. Thanks for the help.

I'd bet that the error message was more elaborate.

At each end.
Zip ("-V") + UnZip should work, but it requires more storage space at
each end (at least for a while), and more CPU time. Setting the file
attributes is simpler/faster, unless your file-transfer scheme actually
changes the data (like an ASCII FTP transfer, for example).
But, it's your storage and your time.
