-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I'm writing a layer 2.5 ad-hoc network driver, that sits between IP (and friends) and physical device drivers. Although all looks good to me, I still can't ping across the link. Outgoing packets look fine (and look like ARP requests like they should), and the incoming packets on the other machine match, so nothing's getting scrabled on the way through. Nevertheless, IP isn't responding to the ARP requests, so nothing happens, apart from ping saying 'Destination host unreachable'. The network device is initialised with ether_setup(). Debug statements look like: Node A (ping source) (event.c:57) Waiting for packets (event.c:98) Getting TX queue... (queue.h:90) Dequeuing item 12 (at 12144); Queue head 13, tail 13, len 0 (event.c:120) Got outgoing packet of len 42 (tx.c:64) Got outgoing packet to 255.255.255, containing: ff ff ff ff ff ff 00 00 00 19 94 c8 08 06 | 00 01 08 00 06 04 00 01 00 00 00 19 94 c8 0a 00 00 02... (event.c:125) Releasing TX queue... Node B (ping destination) (event.c:57) Waiting for packets (event.c:143) Getting RX queue... (queue.h:90) Dequeuing item 24 (at 13168); Queue head 25, tail 25, len 0 (event.c:165) Got incoming packet of len 46 (sahnr.c:193) Got broadcast packet, id 21 (common.c:56) Allocating 79 bytes of memory (rx.c:113) Incoming packet contents: ff ff ff ff ff ff 00 00 00 19 94 c8 08 06 | 00 01 08 00 06 04 00 01 00 00 00 19 94 c8 0a 00 00 02... (event.c:177) Releasing RX queue... Is there something obvious that might be stopping IP from seeing the incoming packets? Have I missed anything? I'm not sure how much detail to include.
