We are evaluating the blackbox sftp client, but are having some issues getting it to work with a tumbleweed sftp server.

I am attempting to upload a file to a tumbleweed server using the .Net SFTP Client. I am able to log into the server (we are using RSA certificates), but am receiving the following error when uploading the file (see below). I've tried setting autoAdjustTransferBlock to false and pipelineLength to 1, but I get the same error.

I am able to manually upload the file using Core FTP as a client (using SFTP). So, it seems that the server is configured ok and working.

Also, we are able to get it to work against our in house Serv-U sftp server. Perhaps there are specific settings we need to make with the blackbox sftp client in order for it to work with a tumbleweed server?

Any help would be appreciated.

Thank you for the report. Tumbleweed server has serious standard-compliance problems. Moreover, since it's very closed software, we can't even test our implementation with it. So we can only try to guess some settings that don't cause the problem.

So is it possible for you to capture the log of Core FTP and post it here (or create a helpdesk ticket which is private between you and our support)?


Sincerely yours
Eugene Mayevski
