ZHM(8)ZHM(8)NAMEzhm - Zephyr HostManager
SYNOPSIS
/etc/athena/zhm [ -d ] [ -h ] [ -r ] [ -i ] [ 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 -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 optional server arguments are used to replace the set of server
names supplied by the hesiod(3) name server.
