ZHM(8) System Manager's Manual ZHM(8) NAME
zhm - Zephyr HostManager SYNOPSIS
/usr/sbin/zhm [ -d ] [ -n ] [ -h ] [ -r ] [ -i ] [ -f ] [ -N ] [ server ... ] DESCRIPTION
Zhm is the link between a client machine and the zephyr server. All notices sent from programs on the client are funneled through zhm. This allows all client programs to be much simpler in function, since the HostManager is responsible for handling errors, retransmitting lost notices, and holding all notices until they are acknowledged. The -d option turns on debugging mode, and sends its information to syslog LOG_DAEMON messages. The -n option causes zhm to not attempt to put itself in the background. The -h option causes zhm to send a shutdown message and exit upon delivery of a SIGHUP signal. The normal action on SIGHUP is to send a flush notice to the zephyr server. The -r option causes zhm to send a boot notice to the server and exit when the notice is acknowledged. The -i option indicates that zhm is being started by inetd(8). When this option is specified, zhm assumes that file descriptor zero (0) is bound to the UDP datagram port designated for hostmanager use. In this mode, SIGHUP is handled as if the -h option were specified. The -f option disables the "flush" operation which allows any client to flush all subscriptions for the host. The -N option supresses the initial "boot" message that flushes all subscriptions for the host, which is useful if you're restarting zhm on a host that people are using. The optional server arguments are used to replace the set of server names supplied by the hesiod(3) name server. SEE ALSO

ZLEAVE(1) General Commands Manual ZLEAVE(1) NAME
zleave - notify you via Zephyr when you have to leave SYNOPSIS
zleave [ [+]hhmm [ -m Reminder Message ] ] zleave can[cel] DESCRIPTION
Zleave waits until the specified time, then reminds you that you have to leave, using the Zephyr(1) Notification Service. You are reminded 5 minutes and 1 minute before the actual time, at the time, and every minute thereafter. When you log off, zleave exits just before it would have sent the next message. The time of day is in the form hhmm where hh is a time in hours (on a 12 or 24 hour clock). All times are converted to a 12 hour clock, and assumed to be in the next 12 hours. If the time is preceded by `+', the alarm will go off in hours and minutes from the current time. If no argument is given, zleave prompts with "When do you have to leave?". A reply of newline causes zleave to exit, otherwise the reply is assumed to be a time. This form is suitable for inclusion in a .login or .profile. The cancel option cancels the currently running zleave. If another zleave is running, it is automatically killed when a new time to leave is set. The process id is stored in the file /tmp/zleave.uid, where uid is the user's UNIX uid. If the -m argument is specified, the next argument is appended to the standard message (a sentence describing how much time remains until the appointed hour) sent at appropriate times. If you want to append a multiple-word message, you normally must quote it with double quotes (") (This is necessary for users of csh(1) and sh(1).) Zleave automatically subscribes you to Zephyr class "MESSAGE", instance "LEAVE". You do not have to add anything to your default subscrip- tions file (see zctl(1)). The reminder message is displayed by the WindowGram client (usually zwgc(1)). If Zephyr is unavailable, zleave acts essentially like leave(1). Zleave ignores SIGINT, SIGQUIT, and SIGTERM. To get rid of it you should either log off or use the cancel option. FILES
