I am having issues diagnosing what the root of my problem is (is sftp/tftp not working due to a configuration issue on my local laptop or a configuration issue on my linux system).
I have a Debian 7 Whitebox Switch that I am testing. One of the things I have to test is file transfer functionalities. I want to transfer an files to using sftp or tftp. When I try to tftp to my laptop from the whitebox, it will connect but I am unable to transfer files (when I do a tftp get request, it times out).
When I try to use sftp from my local system to the box, it authenticates, but the connection is almost immediately closed with the SFTP error #103. As a note here, the box is configured to use TACACS for authentication over SSH, those credentials were used to authenticate here. I have also tried enabling the root password on the system and authenticating that way does not appear to work either.
As a workaround I was able to use python's SimpleHTTPServer & wget to transfer files, but I need to identify if there is something I have mis-configured or if there is an issue on the system I am testing.
