ZHM(8)ZHM(8)NAMEzhm - Zephyr HostManager
SYNOPSIS
/etc/athena/zhm [ -d ] [ -h ] [ -r ] [ -i ] [ -f ] [
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 acknowl
edged.
The -d option turns on debugging mode, and sends its
information to syslog LOG_DAEMON messages.
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 optional server arguments are used to replace the set
of server names supplied by the hesiod(3) name server.
