I shared a folder on Ubuntu 16.04 to local network and try to set Permissions for "Other Access" to "Create and delete files"
But after setting "Others" to "Read and write" as the following figure
Press "Change" and go back to that "Change Permissions for Enclosed Files...", the changes seem to be reverted back:
How to permanently set "Read and write" access permissions for everybody?
Btw, the "Security context" is always "unkwown" - is this normal behavior?
