I would like know if its possible deny upload files to some users. They can login and check files shared with them but they can't upload any file.
You can set a quota of 0 bytes for those users in the user management of ownCloud.
Thanks, I tried that but if they have 0 bytes they can't see files shared with them. They mustn't upload files but yes see files shared with them.
The quota doesn't affect which files a user can see.
Thanks. Its working.
Really I want to allow access some users only from certain IP, is it possible? I didn't see any way to do it and for that reason I choose to deny upload files. If someone knows any way to do it, please let me know.
No, this is not possible on a default ownCloud community installation. The enterprise edition offers a "file firewall" functionality which might help here.
