Can mikrotik upload to any linux windows or mikrotik?

3

theoretically yes. some times there could be packet size related issues from outside to mikrotik based on size.

4

Packet size is negotiated within ssh protocol, seriously try to upload a file somewhere else.

5

Specification of the source directory missing?
(the target URL specifies location there, but the src-path spec is just the filename qithout absolute path...)

6

have checked that. if i give an invalid source file/path it complains immediately. does not say finished uploading.

found solution here:
https://openwrt.org/docs/guide-user/services/nas/sftp.server
once i installed sftp server it worked without anything as additional configuration.
what was confusing is that the caller came back as success(and nothing in openwrt log about error) while openwrt threw an error about absence of sftp-server (checked manually with sftp root@openwrtdumbap to identify issue)
