# NAME

`mountd` — service remote NFS mount requests

# SYNOPSIS

`mountd` | [`-d`] [exportsfile]

# DESCRIPTION

`mountd` is the server for NFS mount requests from other client machines. `mountd` listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC 1094, Appendix A and NFS: Network File System Version 3 Protocol Specification, RFC 1813, Appendix I.

The options are as follows:

`-d`
  Enable debugging mode. `mountd` will not detach from the controlling terminal and will print debugging messages to stderr.
exportsfile
  The exportsfile argument specifies 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 -HUP `cat /var/run/mountd.pid`), check the syslog output to see if `mountd` logged any parsing errors in the exports file.

# FILES

/etc/exports
  list of exported filesystems
/var/db/mountdtab
  list of exported filesystems currently mounted
/var/run/mountd.pid
  PID of the currently running `mountd`

# HISTORY

The `mountd` utility first appeared in 4.3BSD-Reno.

The `-n` flag historically allowed clients to use non-reserved ports when communicating with `mountd`. In OpenBSD, a reserved port is always used.
