Question about file permission?

Hi, guys, anyone who can answer my question? I have a Virtual Server in freebsd 3. When I login to Virtual Server through telnet, e.g. by user=kevin,password=kevin. Now I access the file "master.passwd" in /etc. But the "permission denied" error comes. NOw tell me that is there any way that I can access that file within the same login(user=kevin,password=kevin) and change the file permissions. Tell me is there any way? Or provide the solution. and also I have no access to the main user (I mean Dedicated server).

The user Kevin cannot access master.password because the file is owned by root and in the group wheel and kevin is not in this group. If you TRUST user kevin, add kevin to the wheel group, and have him/her access /etc/master.passwd by doing su.
