Eric's Tech Notes: macosx

MacOS/X disassembly Tools:

	otool
	c++filt

MacOS equivalent for Linux strace / Solaris truss (ptrace):

	ktrace
	kdump

(Note that in MacOS/X 10.5, Apple removed
ktrace! Don't panic, you can use dtruss instead.)

IPFW Firewall

MacOS/X by default sends out all sorts of broadcasts and multicasts,
including some with personal information about the user. To prevent this,
you can block all outgoing multicast packets:

$ sudo ipfw 6 add deny tcp from any to 224.0.0.0/4
