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 controlling 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 information. 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 file.
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
