更改日志

0.3:

• You can now select type of ARP request. This is done with “arp_type” argument of ArpRequest class. You can use arprequest.ARP_GRATUITOUS to make an ARP Gratuitous request (what is currently done) or use arprequest.ARP_STANDARD to do a standard ARP request.

  This option was created to use this library with systems which are configured to block Arp Gratuitous.

约束条件

• ArpRequest work only on unix or unix-like platforms because it uses unix signals.
• ArpRequest work only as root, because it uses raw sockets.
• Module is commented in french. I will translate comments in english, some day…
