Communication is by .Tn RPC . Three modes of operation are supported by the current protocol. By default a list of mount points and auto-mounted file systems is output. An alternative host can be specified using the .Fl h option. .Pp If directory names are given, as output by default, then per file system information is displayed. .Sh OPTIONS .Bl -tag -width Ds .It Fl f Request automounter to flush the internal caches. .It Fl h Ar hostname Query alternate host .Ar hostname . By default the local host is used. In an .Tn HP-UX cluster, the root server is queried by default, since that is the system on which the automounter is normally run. .It Fl l Ar log_file Tell amd to use .Ar log_file as the log file name. For security reasons, this must be the same log file which .Nm amd used when started. This option is therefore only useful to refresh .Nm amd Ns \'s open file handle on the log file, so that it can be rotated and compressed via daily cron jobs. .It Fl m Request the automounter to provide a list of mounted file systems, including the number of references to each file system and any error which occurred while mounting. .It Fl p Return the process ID of the remote or locally running .Nm amd . Useful when you need to send a signal to the local .Nm amd process, and would rather not have to search through the process table. This option is used in the .Pa ctl-amd script. .It Fl s Request the automounter to provide system-wide mount statistics. .It Fl u Request the automounter to unmount the named file systems instead of providing information about them. Unmounts are requested, not forced. They merely cause the mounted file system to timeout, which will be picked up by .Nm amd Ns \'s main scheduler thus causing the normal timeout action to be taken. .It Fl v Request the automounter to provide version information. This is a subset of the information provided by .Nm amd Ns \'s Fl v option. .It Fl x Ar log_options Ask the automounter to use the logging options specified in .Ar log_options from now on. .It Fl D Ar log_options Ask the automounter to use the debugging options specified in .Ar debug_options from now on. .It Fl M Pass a mount map entry to .Nm amd and wait for it to be evaluated, possibly causing a mount. This option is highly insecure. By default, .Nm amd and .Nm amq do not support it. It is necessary to configure .Nm am-utils with .Ar --enable-amq-mount to enable this option. .It Fl P Ar program_number Contact an alternate running .Nm amd that had registered itself on a different RPC .Ar program_number and apply all other operations to that instance of the automounter. This is useful when running multiple copies of .Nm amd , and need to manage each one separately. If not specified, .Nm amq will use the default program number for .Nm amd , 300019. For security reasons, the only alternate program numbers .Nm amd can use range from 300019 to 300029, inclusive. .It Fl T Contact .Nm amd using the TCP transport only. Normally .Nm amq will try TCP, and if that fails, will try UDP. .It Fl U Contact .Nm amd using UDP (connectionless) transport only. Normally .Nm amq will try TCP, and if that fails, will try UDP. .El .Sh FILES .Bl -tag -width amq.x -compact .It Pa amq.x .Tn RPC protocol description. .El .Sh CAVEATS .Nm Amq uses a Sun registered .Tn RPC program number (300019 decimal) which may not be in the .Pa /etc/rpc database. .Sh SEE ALSO .Xr amd.conf 5 , .Xr amd 8 .Sh AUTHORS .An Jan-Simon Pendry Aq jsp@doc.ic.ac.uk , Department of Computing, Imperial College, London, UK. .Pp .An Erez Zadok Aq ezk@cs.columbia.edu , Department of Computer Science, Columbia University, New York, USA. .Pp .An Other authors and contributors to .Nm am-utils are listed in the .Nm AUTHORS file distributed with .Nm am-utils . .Sh HISTORY .Nm Amq first appeared in .Bx 4.4 .
