Decoding the Packets

If the Decode window that was automatically opened when the Quick Capture was selected was closed,

Dean could always view the decode by selecting Decode from the Capture > Buffers dialog with the buffer

to decode selected.

The Packet Decoder screen provides details of the captured packets. The top window provides a summary

of the packet, including size, source and destination, the highest-layer protocol decoded, and other

information based on the decoded protocol type. Dean can see that the “other” traffic is TCP traffic because

that is the highest layer decoded—no application information is available. Selecting a packet and looking at

the lower window gives a layered breakdown of the details. Dean can see that TCP ports 2020 are used.

Looking at the raw data for one of the packets, Dean notices that this is a Q-Bits database GUI tool in

development. Dean will next add it to the Protocol directory to monitor it by name.
