Getting IP address of a server

Hello,

I have a server in C that is listening on a socket using s_addr = INADDR_ANY, and clients connect to it. How can I know which address did the client use to connect to that socket?

It might be 127.0.0.1 (if the server is running locally), 192.168.x.x (if the client is from inside the same LAN) or any other if the client is connecting from the net.

NAME
emp_hub - Empire multiplexer SYNOPSIS
emp_hub [-persistent] [-debug] [-help] [-mirror] host port localport DESCRIPTION
emp_hub allows multiple clients to simultaneously connect to a single Empire country. This allows you to use both a fast and a smart client simultaneously. It also permits multiple corulers to log in at once. Parameters host Hostname of the upstream server. port TCP/IP port number the empire server is running on. localport TCP/IP port number the emp_hub should listen to for incoming client connections. -mirror Copy commands and replies to all clients using new protocols. Currently only the lafe client is aware of these protocols, though most clients will ignore them. -persistent Normally emp_hub exits after the last client disconnects. With this option emp_hub does not exit, and will wait for new clients to connect. emp_hub must be killed by the user using the kill command. -help Brief usage information. -debug Print lots of messages, including everything sent and received by a client. Useful when debugging either emp_hub , a client, or the server. SEE ALSO
emp_server(6), emp_client(6), emp_hub(6), pei(6), eif(6), http://www.empire.net/~harmless/guide.html, http://empire.idlpaper.com/ BUGS
Due to the nature of the empire protocol, only one client may have input focus at one time. If a client pauses at a context sensitive prompt from the server, all other clients will be unable to send data. AUTHOR
