- * Front end to the ULTRIX miscd service. The front end logs the remote host
- * name and then invokes the real miscd daemon. Install as "/usr/etc/miscd",
- * after renaming the real miscd daemon to the name defined with the
- * REAL_MISCD macro.
- *
- * Connections and diagnostics are logged through syslog(3).
- *
- * The Ultrix miscd program implements (among others) the systat service, which
- * pipes the output from who(1) to stdout. This information is potentially
- * useful to systems crackers.
