question about permissions on files
 

I have a file that has permissions of 777 and the directory the file is in has permissions of 777. When a user writes to the file they get permission denied. I need to know what I need to do to ensure the user can write to this file. What do I have set up wrong or what do I need to change. The user is not the owner, nor part of the group where the file is, they would write under the 'other' category. Thanks in advance.

If a user is unable to create a file in a folder with world writable permissions, I would suggest that either the filesystem is mounted read-only or you have some other Access Control mechanism running.

What distribution are you using?
