I'm on Mac OS X, so tcpdumps: I to freebsd http://pastie.org/327953.txt?key=3Dzaehiz6bxcxs3rjuyfbtyq= freebsd to me http://pastie.org/327954.txt?key=3Dautckpywar1mkngb9re0w I to linux = http://pastie.org/327955.txt?key=3Dklqvsd73l3flhayoykeeq linux to me http://pastie.org/327952.txt?key=3Duu1cpgleuhnctwcuqzxlw However, I'm not sure it's helpful. I mean you can't look inside a =20 packet, because it was encrypted. Headers and packet size depends on =20 many factors. For example, if you compare linux and freebsd tcpdumps =20 here, you'll see that freebsd ignore packet's checksums and linux has =20= tcp timestamps turned off, and so on. > > > --=20 > Mel > > Problem with today's modular software: they start with the modules > and never get to the software part.
