I dont have an advance knowledge of htis but have been playing with packet sniffers for a while now and have couple of questions.
1.although we can figure out which app. a packet is going to by looking at the dest. port no.(for well known ports), but is there any other way to know who(app./service) is the data in a packet going to?
2. Is there a way to look at the payload of a packet in plain text or atleast in more readable form.

Thanks in advance,and please dont laugh if the Q sound silly.
