FileZilla Forums

Hi, when uploading files to our filezilla pro sftp server from cisco c2960x switches it fails on (downloading from sftp to the switch works fine)

"%Error writing sftp://*****@ip.address/switchname-confg (Transfer aborted)"

and the log corresponding to this is

2024-03-01T12:37:13.280Z << [SSH SFTP Session 79 ip.address username] User authenticated successfully [user=username]
2024-03-01T12:37:13.311Z !! [SSH SFTP Session 79 ip.address username] Shell or subsystem '<null>' is not supported.

where should we look for a problem?
our different model cisco switches have no issue downloading or uploading to the sftp server

thanks a lot

FileZilla Pro Enterprise Server only supports SSH's SFTP subsystem, it does not support any other subsystem or shell. Your client tries to open a shell.

How would downloading from sftp the other way work then?

SFTP is the file transfer subsystem and works much like FTP. If the Cisco device supports SFTP, it will simply work when connecting to an SFTP server running on port 22. You need to check its manual for exact configuration.
