Checking for inetd

Having acquired credentials for the service, gss-server checks to see whether the user has specified inetd. The main function checks for inetd as follows:

if (do_inetd) {
     close(1);
     close(2);

If the user has specified to use inetd, then the program closes the standard output and standard error. gss-server then calls sign_server() on the standard input, which inetd uses to pass connections. Otherwise, gss-server creates a socket, accepts the connection for that socket with the TCP function accept(), and calls sign_server() on the file descriptor that is returned by accept().

If inetd is not used, the program creates connections and contexts until the program is terminated. However, if the user has specified the -once option, the loop terminates after the first connection.
