NAME

       cnid_metad - start cnid_dbd daemons on request

SYNOPSIS

       cnid_metad [-l loglevel [-f filename]] [-d] [-h hostname] [-p port]
                  [-u user] [-g group] [-s cnid_dbdpathname]

DESCRIPTION

       cnid_metad waits for requests from afpd to start up instances of the
       cnid_dbd daemon. It keeps track of the status of a cnid_dbd instance
       once started and will restart it if necessary.  cnid_metad is normally
       started at boot time from /etc/rc or equivalent and runs until
       shutdown.  afpd needs to be configured with the -cnidserver option in
       afpd.conf in order to access cnid_metad.  It is possible to run more
       than one instance of cnid_metad on the same machine if different values
       for the interface and/or port are specified with the -h and -p options.

OPTIONS

       -l <loglevel> [-f <filename>]
           Specify that any message of a loglevel up to the given loglevel
           should be logged to the given file. If the filename is ommited the
           loglevel applies to messages passed to syslog. Default is logs to
           syslog with a default logging setup of "log_note".

           Note: cnid_metad passes this to cnid_dbd which will in turn use
           this for its logging setup.

           loglevels: LOG_SEVERE, LOG_ERROR, LOG_WARN, LOG_NOTE, LOG_INFO,
           LOG_DEBUG, LOG_DEBUG6, LOG_DEBUG7, LOG_DEBUG8, LOG_DEBUG9,
           LOG_MAXDEBUG

           Example. Useful default config

               -l log_info -f /var/log/afpd.log

           Example. Debugging config

               -l log_maxdebug -f /var/log/afpd.log

       -d
           cnid_metad will remain in the foreground and will also leave the
           standard input, standard output and standard error file descriptors
           open. Useful for debugging.

       -h hostname
           Use hostname as the network interface for requests as opposed to
           the default localhost. The network address may be specified either
           in dotted-decimal format for IPv4 or in hexadecimal format for
           IPv6.

       -p port
           Use port as the port number for reqests. Default is 4700.

       -u user
           Switch to the userid of user before serving requests. This userid
           will be inherited by all cnid_dbd daemon processes started.

       -g group
           Switch to the groupid of group before serving requests. This
           groupid will be inherited by all cnid_dbd daemon processes started.
           Both user and group must be specified as strings.

       -s cnid_dbd pathname
           Use cnid_dbd pathname as the pathname of the executeable of the
           cnid_dbd daemon. The default is /usr/sbin/cnid_dbd.

CAVEATS

       The number of cnid_dbd subprocecesses is currently limited to 512.

       cnid_metad does not block or catch any signals apart from SIGPIPE. It
       will therefore exit on most signals received. This will also cause all
       instances of cnid_dbd´s started by that cnid_metad to exit gracefully.
       Since state about and IPC access to the subprocesses is only maintained
       in memory by cnid_metad this is desired behaviour. As soon as
       cnid_metad is restarted afpd processes will transparently reconnect.
