- /*
- * General front end for stream and datagram IP services. This program logs
- * the remote host name and then invokes the real daemon. For example,
- * install as /usr/etc/{tftpd,fingerd,telnetd,ftpd,rlogind,rshd,rexecd},
- * after saving the real daemons in the directory specified with the
- * REAL_DAEMON_DIR macro. This arrangement requires that the network daemons
- * are started by inetd or something similar. Connections and diagnostics
- * are logged through syslog(3).
