I need to give access to a few people to upload some large (video) files to a server i manage. For myself, I'd use
scp but as they are not me, I don't want to give them full
scp) access to the server just for that as I don't necessarily know all of the people and it would be counted as a plus if the users didn't have access to each other's files.
What would be the best and most secure way to provide uploads to the server? What kind of modifications would this cause to any existing firewall rules (basically allowing only ports 22 and 80/443 but with QoS in place)?
The server is running Ubuntu 9.04. Clients range from Linux through Mac OS X to various versions of Windows.
