The documentation is pretty thin in this area, so any help or suggestions would greatly be appreciated. I think you will have to use gdb, or some really creative syslogs. Yes I have checked to make sure that pHeader and ifb->nfliter_id are pointer or contain the correct information. Huh? Cheers, Justin -- Justin C.

Ok this is driving me crazy, as you probable know from my other messages I am filtering packets at the DLIL interface layer, my problem is that when ever I call dlil_inject_if_input my Mac crashes. You can, of course, use gdb to figure out where in the code the crash occurs: - use 2-machine debugging to catch the varmint in the act; - if you get a panic, the values printed either in the panic log or to the screen can be handed to gdb to get a stack trace. Then, you can track backwards with code in hand to figure out what is going wrong. This email sent to site_archiver@lists.apple.com
