1. Capture some data using tcpdump:

   tcpdump -enx -w cassandra-dump port 9160

2. Open the file with wireshark and find a packet where the data looks related to casandra e.g. it has multiget_slice or similar commands near the start of the data.

3. In wireshark select the data part of the packet and right click -> copy -> bytes -> hex stream

4. Now you need a thrift library to decode the data. thobbs/phpcassa should work.
