Is ICMP allowed? I remember an old colleague writing a steganographic file transfer agent that transfered files slowly with ping packets. An ICMP ECHO_REQUEST of 56 bytes was a zero. And an ICMP ECHO_REQUEST of 64 bytes was a one. ICMP ECHO_REPLY was confirmation of receipt! Would that be slow enough? :P
- RiderOfGiraffes 16y agoInteresting idea! And it would certainly be slow enough. However, it's not really what I'm looking for ... It looks like I'll implement something similar to FSP - there doesn't seem to be anything like what I need "off-the-shelf" Much appreciation to those who replied - I've learned a lot that may be useful.
