The Linux code seems to blindly hijack the PF_KEY domain and excuses doing so with a rather lame comment that anything else using it would conflict with the module anyway so it's OK. I'd rather not do this on darwin / MacOS X and am eyeing the NKE Manager. Conceptually I think I get it. It marshals connections to a domain specifically create to allow userland code to find an NKE based on its handle. Yes; PF_NKE (pre 10.2, in any case) is what you want. There was some discussion of merging the (somewhat immature) PF_NKE implementation into PF_SYSTEM, and improving it, but I don't know how far that got (and I haven't spent any time with 10.2, to see whether it's been done). The NKE Manager is the support for PF_NKE, so that should get you started. You're right, hijacking PF_KEY would be bad since PF_KEY is used for Mac OS Xs IPSec implementation. The NKE Manager is one way to go. With Jaguar, there is a better way using a PF_SYSTEM socket. I can not recall the details unfortunately. Perhaps someone else in the know will respond? As for the NKE Manager, there should be a sample NKE that makes use of it. Again, I can't recall the details. I'll ask around and see if anyone remembers. 'TCPLogger' is the NKE; the user program that uses it is 'tcplog'. Regards, Justin -- Justin C.
