- Checking the NFS server daemon
The script required for normal operation of NFS services is
/etc/rc.d/init.d/nfs
.
Portmap
This service connects RPC services to TCP/UDP ports. An RPC program once started will tell
portmap the service that it provides and the port that it uses. And a client contacts portmap to
identify the port number through which it can access the server that it wants. Do the following if
you want to make sure that portmapper is running on Linux.
Rpm.cmountd responds to a mount request coming from a client. For a NFS client to be able to
use a file system of a server, the server needs to set its file system in a way that it can be
shared through NFS. The file /etc/exports is used on Linux. The file system of the server should
be mounted for a NFS client to share it. When the NFS client requests a mount, the rpc.mountd
daemon responds to such mount request according to configuration of the /etc/exports file.
