call to succeed, and must give up those privledges as soon as the new
root has been aquired. Use setgid() & setuid() to explicitly set the
user and group IDs to non- priveleged values.
This change now requires tftpd to be executed by root. I haven't
studied the security implications of making it setuid root, so
inetd.conf needs to be changed to start it as root.
As promised. the problem was that tftpd would core dump if given no arguments.
I fixed it to use getopt. I also changed 0 to fd, because I had added some
debugging code that allowed me to start it from the command line.
