SAS Sftp connection issue

[Wangya1]

Currently I'm trying to use sas to connect to sftp server. I did some researches, it said in order to use sftp method, I need to install openSSH client software and use key authentication for connection.

So I installed puTTY and setup the private/public key. When I test the connection from psftp, I can connect to sftp server without password (use key authentication). As you can see as below, the test file 3.xlsx is on the sftp server.

But the problem is when I try to get the same file on sas, it has an error "the file does not exist".

Inside psftp, I could download this test file on my local pc, I have no idea why I cant do the same thing on sas.

Below is my sas sftp connection code:

filename test sftp '/3.xlsx'
optionsx='-P 222 -i x:\PuTTY\privatekey.ppk -pw "XXXXXXX" -V'
host="XXXXXXXX" user="XXXXXXXX" path="x:\PuTTY\psftp.exe" DEBUG;

I would be so appreciate if someone can help me to fix this issue.

By any chance did you try starting that filename statement with

filename test sftp '3.xlsx'

no preceding /

I tried, its not working. Even if I just want to test with simple cmd like 'LS', I still get error msg like "file '' does not exist'.

I don't know enough, basically nothing, about Putty.

Had you found either of these:

That seem to provide more concrete details.
