Sender: bluez-users-admin@lists.sourceforge.net Errors-To: bluez-users-admin@lists.sourceforge.net Reply-To: bluez-users@lists.sourceforge.net List-Unsubscribe: , List-Id: BlueZ users List-Post: List-Help: List-Subscribe: , List-Archive: Date: Mon, 21 Feb 2005 14:02:07 +0100 Hi all. I am working with a single USB dongle in a Linux laptop with BlueZ and two PAN-profile access points connected to the same LAN. Each access point is implemented with a PC with bridge-utils and bluez packets installed. I stablish two simultaneous PAN connectionsfrom the laptop: each one to a different access point. Having both connections would prevent the loss of data between the LAN and the laptop. I would like to receive all the packets through both connections, in order to have redundancy. I configure both resulting bnep interfaces to have the same IP address, since I don't want the other side of the communication to know the existence of two different paths. When I do "ifconfig" in the laptop, I realize that both bnep interfaces show the same hardware address, which would let my laptop receive each packet from the LAN twice. But the reality is that only one of the interfaces at a time receives the packets. For example, when "ping" my laptop from a computer connected to the LAN, only bnep0 receives ICMP requests, and bnep1 doesn't. If I use the metrics of the routing table to force bnep1 to answer the ping, then ICMP requests start to be received by bnep1, and bnep0 receives nothing now. I would like to know if this issue depends on the bnep implementation and also would like to know how can the net make differences between both interfaces, as they have same MAC and IP addresses. Thanks a lot. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
