It is probably worth pointing out that it is FSF ls(1) at fault here; wu-ftpd just provides a convenient way for potentially unauthenticated users to DoS the machine. If your OS supports rlimits (ulimit(3)), I believe they will provide reliable protection against this problem. -- http://www.immunix.com/ secure Linux distributions and appliances
