MOUNTD(8) NetBSD System Manager's Manual MOUNTD(8)
NAME
mountd -- service remote NFS mount requests
SYNOPSIS
mountd [-dN] [-P policy] [-p port] [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, Appendix I.
Options and operands available for mountd:
-d Enable debugging mode. mountd will not detach from the con-
trolling terminal and will print debugging messages to
stderr.
-N Do not require privileged ports for mount or NFS RPC calls.
This option is equivalent to specifying `-noresvport
-noresvmnt' on every export. See exports(5) for more infor-
mation. Some operating systems (notably Mac OS X) require
this option.
-P policy IPsec policy string, as described in ipsec_set_policy(3).
Multiple IPsec policy strings may be specified by using a
semicolon as a separator. If conflicting policy strings are
found in a single line, the last string will take effect. If
an invalid IPsec policy string is used mountd logs an error
message and terminates itself.
-p port Force mountd to bind to the given port. If this option is
not given, mountd may bind to every anonymous port (in the
range 600-1023) which causes trouble when trying to use NFS
through a firewall.
exportsfile
The exportsfile argument specifies an alternative location
for the exports(5) file. Multiple exports files can be
defined.
When mountd is started, it loads the export host addresses and options
into the kernel using the nfssvc(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.
After receiving SIGTERM, mountd sends a broadcast request to remove the
mount list from all the clients. This can take a long time, since the
broadcast request waits for each client to respond.
FILES
/etc/exports the list of exported filesystems
/var/run/mountd.pid the pid of the currently running mountd
/var/db/mountdtab the list of remotely mounted filesystems
