CNID_METAD(8) Netatalk 2.2 CNID_METAD(8)NAMEcnid_metad - start cnid_dbd daemons on request
SYNOPSIScnid_metad [-l loglevel [-f filename]] [-d] [-h hostname] [-p port]
[-u user] [-g group] [-s cnid_dbdpathname]
cnid_metad-v | -V
DESCRIPTIONcnid_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.
-v, -V
Show version and exit.
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.
