55 * Date: Thu, 04 Dec 1997 19:55:01 +0300
56 * ============================================================================
58 * Working on setting up a proper firewall for a network containing some
59 * Win'95 computers at our Univ, I've discovered that some smart students
60 * avoid the restrictions easily just changing their IP addresses in Win'95
61 * Contol Panel... It has been getting boring, so I took Squid-1.1.18
62 * sources and added a new acl type for hard-wired access control:
64 * acl <name> arp <Ethernet address> ...
68 * acl students arp 00:00:21:55:ed:22 00:00:21:ff:55:38
70 * NOTE: Linux code by David Luyer <luyer@ucs.uwa.edu.au>.
71 * Original (BSD-specific) code no longer works.
72 * Solaris code by R. Gancarz <radekg@solaris.elektrownia-lagisza.com.pl>
