rpc.mountd(8) System Manager's Manual rpc.mountd(8) NAME rpc.mountd - NFS
mount Daemon SYNOPSIS/usr/sbin/rpc.mountd [options] DESCRIPTION
rpc.mountd Daemons for implementationNFS Server sideNFS MOUNT Agreement.
NFS The server will maintain aNFS Table of the local physical file system accessed by the client. Each file system in the table is called Exported file system, Or export item for short.
Each file system in the export table has a separate access control list(acl).rpc.mountd Use theseacl To decideNFS Client
Whether to allow access to the corresponding file system. About how to manageNFS Export table of server, See alsoexport(5) andexportfs(8) Of man File. Mounting
exported NFS File Systems NFS MOUNT The protocol consists of several processes. The main thing isMNT(mount an
export) andUMNT(unmount an export). MNT The request has two parameters: An explicit parameter, It contains the path to the root of the exported item to be mounted, There is also an implicit parameter,
It means thatMNT Request sender'sIP address. WhenNFS Sent by clientMNT When the request is received,rpc.mountd Check pathnames and sender'sIP address, If
The sender is allowed to access the requested export item,rpc.mountd Will return aNFS File handle to client.
The client can then use the root file handle,NFS The file lookup request for can also be traversed in the directory structure of the exported item. The rmtab File
wheneverMNT Request successful( The export item is successfully mounted),rpc.mountd All will be directed towards/var/lib/nfs/rmtab Write a message in the file.
When received fromNFS Client sideUMNT Request time,rpc.mountd Will simply/var/lib/nfs/rmtab Remove corresponding in file Corresponding item.
Client can useshowmount(8) Command detectionNFS List of file systems exported by the server, Or list other clients of the server End mounted export file system.showmount(8

Specify a highly available calling program(callout program). The program will receive allMOUNT andUNMOUNT Arousal of request.
This makesrpc.mountd Can be used for high availabilityNFS(HA-NFS) Environmental Science. This call up program uses4 Parameters to run. The first parameter ismount orunmount Causes of arousal(The
first ismount or unmount depending on the reason for the
callout). The second parameter is runningmount Client Name. The third parameter is the export path the client is mounting. The fourth parameter is the concurrency of the client with the pathmount number(The
last is the umber of concurrent mounts that we believe the client has of that
path ). staykernel2.6 And later versions do not need to specify the calling program. Instead, takeNFS The file system is mounted on the /proc/fs/nfsd upper. -s,

supporting NFS on IPv6. If TI-RPC support is built into rpc.mountd, it attempts
to start listeners on net work transports marked'visible' in /etc/netconfig.As
long as at least one network transport listener starts successfully, rpc.mountd
