I have written a couple of servers that work with inetd and I need to be able to get the IP of the connected host.

So, how do I get the remote socket from the stdin handle?

If you are using the FILE * stdin, you can get the file handle using the fileno() function.

struct sockaddr_in sin;
int slen = sizeof(sin);
int rc = getpeername(fileno(stdin), &sin, &slen);

I suspect that the result from fileno(stdin) is 0, since stdin is
always handle 0 and inetd dups its socket as handle 0 before spawning your server.
