Question
Using the latest TPROXY with the Linux Kernel, how would I get the IP address of the remote/destination machine? I am assuming that the local/source endpoint is returned from accept()
.
Solution
The original (before rerouting) remote destination will be in getsockname()
. accept()
will return the local (local enough BUT NOT an interface on the computer) source address.
