User rights

I wan to create a user e.g. Tom. whenever a file is created by user Tom or FTP is done using user as Tom, the rights on the file should be 777 (by default). how can I achieve this. Please help. Its very urgent.

Helo. I thing there is a thread about this on this forum, Try to search.
Anyway, you can force the perms for the files created bay this user either directly loging on the system or by ftp. But not 777, at least for files (yes for directories).
man ksh
man umask
man ftpd
Regards.
