    NAME

    
    
    mountd
    
     - service remote
    
    NFS
    
    mount requests
     
    

    SYNOPSIS

    [-2dlnr ] [-h bindip ] [-p port ] [exportsfile ... ]  

    DESCRIPTION

    The 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. will not detach from the controlling terminal and will print debugging messages to stderr.
    -h bindip
    Specify specific IP addresses to bind to for TCP and UDP requests. This option may be specified multiple times. If no -h option is specified, will bind to INADDR_ANY Note that when specifying IP addresses with -h will automatically add 127.0.0.1 and if IPv6 is enabled, ::1 to the list.
    -l
    Cause all succeeded 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.
    -p port
    Force to bind to the specified port, for both AF_INET and AF_INET6 address families. This is typically done to ensure that the port which binds to is a known quantity which can be used in firewall rulesets. If cannot bind to this port, an appropriate error will be recorded in the system log, and the daemon will then exit.
    -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 flag.
    exportsfile
    Specify an alternate location for the exports file. More than one exports file can be specified.

    When 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 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 logged any parsing errors in the exports file.

    If 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, exits with an error.  

    FILES

    /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

    HISTORY

    The utility first appeared in BSD 4.4
