 To generate corpus for these targets, you can do the following, not fully automated steps :

 * Extract tcp payloads, for instance with tshark : `tshark -Tfields -e tcp.dstport -e tcp.payload -r test.pcap > test.txt`

 * Finally, you can add the options by appending the last bytes to the file test.cor
