I use bpf for similar things. How much does your ip device differ from bpf? What I really want is some sort of simple mechanism to put probes into my code (only during debugging, so it's not normally part of the kernel) and save the output (e.g., probe id, timestamp, probed var) for post processing. I've done this so far in the primitive way with printf/tcp_debug and syslog but I'd like to have something more efficient (low overhead, accurate timestamps). > -- > -=Ugen J.S.Antsilevich=- Andras
