[tproxy] FW: tproxy getsockopt call

[Andrew Ivins]

Hi,

Bit of a low level question, again probably one for Krisztian.

One of our developers is trying to ascertain what the original peer
addresses are on a tproxy socket. In the code snippet below, he prints
out the original source and destination addresses. However they are
always zero.

Does anybody know the correct way of doing this? We are still using
cttproxy-2.4.25-1.9.3.
