They don't need physical access, but at least network access to an account (login/password) on the system. If you haven't set up accounts for others or given out your password, no one will be able to cause this problem. > If its not a big security threat do i > still need to setup user limits ?

If you have something important, back it up to removable media (CD/DVD/tape/USB hard drive, etc.) and keep it offline. You are more likely to have a hardware disk problem or make an error yourself that damages the files than to have a security related problem. Good backups will save your data either way. -- Les Mikesell les@xxxxxxxxxxxxxxxx
