I have a newly setup server that is dedicated to hosting scientific data files. The files are being uploaded, currently manually (but it will be automatically in future) by a very competent user.
The main consumer of these files is, frankly, a liability and so I'm keen to restrict his access only to the directory that the files are sitting in just because he's perfectly capable of deleting anything!
He will be getting access using WinSCP.
How do I set his rights so that all he can see (and screw up) is the folder/directory that I want him to see and no other? Is that do-able within Virtualmin/Webmin or do I have to do it through Linux (which I'm pretty weak at)?
