I'm looking secure way to one-way mirror directory between windows hosts over the internet.
Host A - Has directory with files. Should run some sort of server on single open port X. Everything else is blocked at firewall level that I don't have access to. (Tried to use Filezilla FTPS server but passive mode data-connection would not initialize, because everything else is blocked).
Host B - Windows Scheduled task should run every 5 mins some sort of client program to connect Host A and download new files (and changed files). (First thought was to use lftp.exe with mirror option)
Files are small log files. What would be most stable and preferably freeware/opensource solution for this?
