Hi Harley, Thanks for the response. As I mentioned in my post, I used lsof to check that no other process has the device open. In addition, using an earlier version of libpcap (modified in-house but based on 0.5 or thereabouts) works fine on the same box. Is there any reason why earlier versions of libpcap would allow devices to be opened more than once, but the newest version wouldn't? I'm pretty sure there isn't (as it seems to just be a limitation of dlpi), which makes me pretty sure that there's no other processes interfering.
Thanks again, Justin On 6/8/06, Harley Stenzel <[EMAIL PROTECTED]> wrote:

On HP-UX, unlike Linux and (iirc) Solaris, only one process may have an interface open at a time. I double checked this on my ia64 HP-UX 11.23 box, and this is the behavior I observed. Is it possible another libpcap / streams / dlpi process is running? > Thanks, > Justin --Harley - This is the tcpdump-workers list. Visit https://lists.sandelman.ca/ to unsubscribe.
