Hello, I've been trying to get libpcap 0.9.4 to work on several HP-UX boxes, and am unfortunately having some trouble when I try to open an interface using pcap_open_live. The error I receive is:
recv_ack: promisc_phys: UNIX error - Device busy This occurs when pcap_open_live() calls dlokack(), which in turn calls recv_ack(). I have now received this error on two HP-UX boxes - one running version 11.00 and the other running 11.23. A third box, running 11.11, receives a similar error: "recv_ack: promisc_phys: UNIX error - Invalid argument". I've had no problems using libpcap on Linux, Solaris, or AIX. Furthermore, we've used earlier versions of libpcap (0.5.something, I believe) and haven't encountered any problems. Having searched this mailing list and the Ethereal mailing list (and google in general), it seems I'm not the first to receive the error, but I haven't found any solution to make it go away. (Apparently HP-UX does not allow an interface to be opened twice, but nothing else has opened the interface. In fact, I downloaded lsof for the 11.23 box and it reports that nothing has opened lan0.) I'd appreciate any advice anyone can offer. Thanks, Justin - This is the tcpdump-workers list. Visit https://lists.sandelman.ca/ to unsubscribe.
