hostname

resolution

What is hostname resolution and

why do I care about it?

•Hostname resolution is the mapping of a computer’s

hostname to its network address (typically an IP address)

and vice versa.

•At some point, most every component of NFS needs to

resolve a hostname or IP address

Ø NFS mount(1M) command

Ø rpc.mountd

Ø rpc.lockd & rpc.statd

Ø automount & AutoFS

Most network-based applications, particularly client/server based applications, rely

on hostname resolution services to function correctly. NFS is no exception.

Whether it be an NFS client system attempting to mount a remote filesystem

(manually or via an automounter), an NFS server system processing the mount

request and determining whether the client is allowed to access the requested

filesystem, or a client application attempting to lock an NFS-mounted file, hostname

resolution is involved.
