About sniffers

[R.O.]

Hi,

I am looking for a web-page or something like it, to know the meaning of the messages that i can see when I use tcpdump, in example:

14:57:56.776267 xxxxxxx.51391 > yyyyyy: . ack 1569 win 32768 (DF) [tos 0x10]
14:57:56.804654 xxxxxxx.51391 > yyyyyy: P 0:20(20) ack 1597 win 32768(DF) [tos 0x10]
