Getting ip address of of source in server

[03psb]

I'm working on ACCEPT part of the code, and I figured out it is hard to find the ip address of the client. TCP packets doesn't contain informations of ip address. and the following Tip: Figuring out the source IP address to use (https://github.com/ANLAB-KAIST/KENSv3/wiki/Tip:-Figuring-out-the-source-IP-address-to-use) was not helpful, because I found this method doesn't work on finding address of source. But anyway accept function should return the address of client. I wonder how?

The packet of packetArrived() contains all addresses including MAC and IP. You can parse the packet to retrieve source IP address.

I checked the packet class in E_packet.cpp, I found no sign of method doing that or field that contains potential IP. Can you be more specific please?

You should parse packet's data according to protocol headers (Ethernet, IPv4, and TCP).
To understand how a packet is structured, refer to the textbook pp. 260-263, 360-363, 508-518.
