Traditional authentication with wireless lan's consist of the following simplified procedure: 1). Wireless nic asks for an IP 2). Base station checks to see if the MAC Address can be passed. 3). If the authentication is successful then the DHCP server leases an IP to the Wireless nic. Today, I have circumvented the MAC Address authentication method, and had also sniffed successfully on a switched network with wireless stations on it without authentication into the network. For sniffing onto a wireless network without a registered MAC Address AND using WEP Encryption Methods: 1). Set the MAC Address of the card to 127.0.0.1 and the Netmask to 255.255.0.0 2). The card takes care of the rest. Just sit back and listen to the sounds of the network (NOTE: There will NOT be any DNS RESOLVING and quite possibly NO IP's will show up, only the computers MAC Addressed) (Double NOTE: All you need is another machines MAC Address to start a Man-in-the-Middle). For Getting an IP Address for Internet Connectivity: First Method requires that you have already sniffed on the network for an extended amount of time. Needed information is the IP Ranges, Netmask, and Gateway of the Lan. All of this can be acquired through HUNT. All you do is sift through the data generated, find an IP that hasn't sent any traffic take it and configure the other things (such as Netmask and Gateway manually). Second method requires you to have physical access to the lan. Take a hardwired nic and spoof it's MAC Address to that of the wireless nic's address. Run a command like 'pump,' swap cards and you should be on the network. The following instructions were executed on a Dell laptop with Redhat 7.0. The Ethernet card that was used is a Xircom 10/100 56k Combo thingy and the wireless lan card is a Lucent Technologies Wavelan Gold Turbo 128RC4. The base stations that these were tested on is a D-Link 1000AP, Orinoco AP-1000 Access Point, Orinoco COR-1100, and Cisco Aironet 350 Series. Will someone else please confirm that this is successful?
