Restrict a User from Uploading Files?

[rick_ca]

I am wondering how I can restrict a user from uploading any files. Basically I am using a Linux server to host website files for web development projects for clients and I want to let the clients login to the machine using NX server (remote access) so they can view the files but I do not want them to be able to in any way remove the files from the machine until I authorize them to.

Directory permissions. Set the directory to read only.

Thanks, this would work under normal circumstances however the catch here is that I need them to be able to edit the files but not download them to their own computer (upload from my machine)

I'm not sure how you expect this to work.
If they can read them they can copy/download them.

I Agree with you,
How can you restrict your client from downloading your files, if your client able to read that files?

They are accessing the files through an NX client (NoMachine NX - Desktop Virtualization and Remote Access Management Software) so they need to be able to use the files but not remove them from the server, I guess there is no easy solution to this

Again, if you want them to be able to use the files but not remove them then you should be looking at the directory setting to allow read only. Client will be able to use the files but not delete them.

This software you want to use doesn't have this as an option?

There is absolutely no solution for this. It's a fundamental
characteristic of the way things work. When they read or edit the files,
their computer reads or edits a locally cached copy. They already
have a copy of the file as soon as it appears on their screen.

No this isn't correct, you aren't understanding what NX is (NoMachine NX - Desktop Virtualization and Remote Access Management Software) its a remote access software so they do not download any of the files, nothing is cached locally on their machine

Are your users using diskless workstations? I still don't see how
they can see and edit files and be prevented from keeping a copy.
Maybe the support people from the software company can provide
a solution.
