I have a little embedded device directly connected to a laptop via a crossover cable. I'm monitoring the traffic between the two using Wireshark and I witness a TTL of 30 for TCP packets coming from the device (when they reach the laptop).
What is the device's initial TTL? I'm thinking it could either 30 or 32?
I guess my question is does the hop count decrease over a cross over (I suspect it does but not sure)?
