NAME
mountd
- service remote
NFS
mount requests
SYNOPSIS
mountd
[-dNn]
[-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
RFC 1094, Appendix A and
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.
- -n
-
This flag used to indicate that clients were required to make requests
from reserved ports, but it is now no longer functional. It
is only provided for backwards compatibility. Requests
are checked for reserved ports on a per-export basis, see
exports(5).
- -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.
