NAME    [Toc]    [Back]

     mountd -- service remote NFS mount requests

SYNOPSIS    [Toc]    [Back]

     mountd [-2dlnr] [exportsfile]

DESCRIPTION    [Toc]    [Back]

     The mountd utility is the server for NFS mount requests from other client
     machines.	It listens for service requests at the port indicated in the
     NFS server specification; see Network File System Protocol Specification,
     RFC1094, Appendix A and NFS: Network File System Version 3 Protocol
     Specification, Appendix I.

     The following options are available:

     -2      Allow the administrator to force clients to use only the version
	     2 NFS protocol to mount file systems from this server.

     -d      Output debugging information.

     -l      Cause all succeeded mountd requests to be logged.

     -n      Allow non-root mount requests to be served.  This should only be
	     specified if there are clients such as PC's, that require it.  It
	     will automatically clear the vfs.nfsrv.nfs_privport sysctl flag,
	     which controls if the kernel will accept NFS requests from
	     reserved ports only.

     -r      Allow mount RPCs requests for regular files to be served.
	     Although this seems to violate the mount protocol specification,
	     some diskless workstations do mount requests for their swapfiles
	     and expect them to be regular files.  Since a regular file cannot
	     be specified in /etc/exports, the entire file system in which the
	     swapfiles resides will have to be exported with the -alldirs

	     Specify an alternate location for the exports file.

     When mountd is started, it loads the export host addresses and options
     into the kernel using the mount(2) system call.  After changing the
     exports file, a hangup signal should be sent to the mountd daemon to get
     it to reload the export information.  After sending the SIGHUP (kill -s
     HUP `cat /var/run/mountd.pid`), check the syslog output to see if mountd
     logged any parsing errors in the exports file.

     If mountd detects that the running kernel does not include NFS support,
     it will attempt to load a loadable kernel module containing NFS code,
     using kldload(2).	If this fails, or no NFS KLD was available, mountd
     exits with an error.

FILES    [Toc]    [Back]

     /etc/exports	  the list of exported file systems
     /var/run/mountd.pid  the pid of the currently running mountd
     /var/db/mountdtab	  the current list of remote mounted file systems
