We have an external party connecting via SFTP to our Gateway, with SSH certificate credentials. When they connect to the gateway, they use the CD command to change directory to the policy. This works fine, and they are able to PUT a file, and the policy processes it without any issues.
However. In doing so, a number of client side errors are raised: specifically, the SFTP client is trying to use the LIST or STAT command presumably to check the file exists first, or to validate that the file is uploaded successfully – this seems to be a standard function of the “open source” command line “sftp” included with MacOSX / Linux.
Has anyone seen this at all, and do you have to implement anything within your policies to handle the LIST/STAT commands?
