  2.    smack.c [code released - Oct 23rd 1998 by - Iron-lungs]
  3.    http://www.legion2000.org
  4.  
  5.    Derived: Based on a old D.o.s exploit used to crash large quake servers.
  6.  
  7.    Overview: sends random Icmp unreachable packets from random ip#'s -
  8.  
  9.    Result:  Result is a basic lock up on all windows platforms even affects , BSD , Redhat and
  10.    slackware versions. The user will instantly recieve the packets by the 1,000's , resulting
  11.    in a large boost of CPU , aventuly they have no response to their browser , ftp , telnet and
  12.    other such clients as ICQ and mIRc also reset.
  13.  
  14.    Tip: try using this exploit with the repeat method "eg: ./smack 127.0.0.1 ; ./smack
  15.    127.0.0.1 "
  16.  
  17.    Finishing comments: No responsibility is taken from the results of this script, use at risk.
  18.  
  19.           /smack.c is a addition for ultrsmack.tar.gz which has yet to be released /
