.Dd March 12, 2016 .Dt MOUNTD 1M .Os .Sh NAME .Nm mountd .Nd server for NFS mount requests and NFS access checks .Sh SYNOPSIS .Nm /usr/lib/nfs/mountd .Op Fl rv .Sh DESCRIPTION .Nm is an RPC server that answers requests for NFS access information and file system mount requests. It reads the file
a /etc/dfs/sharetab to determine which file systems are available for mounting by which remote machines. See .Xr sharetab 4 . .Nm nfsd running on the local server will contact .Nm the first time an NFS client tries to access the file system to determine whether the client should get read-write, read-only, or no access. This access can be dependent on the security mode used in the remoted procedure call from the client. See .Xr share_nfs 1M .
p The command also provides information as to what file systems are mounted by which clients. This information can be printed using the .Xr showmount 1M command.
p The .Nm daemon is automatically invoked by .Xr share 1M .
p Only super user can run the mountd daemon.
p See .Xr nfs 4 for available configuration properties for .Nm . .Ss Options The options shown below are supported for NFSv2/v3 clients. They are not supported for NFSv4 clients. l -tag -width Ds t Fl r Reject mount requests from clients. Clients that have file systems mounted will not be affected. t Fl v Run the command in verbose mode. Each time .Nm determines what access a client should get, it will log the result to the console, as well as how it got that result. .El .Sh FILES l -tag -width Ds t Pa /etc/dfs/sharetab shared file system table .El .Sh SEE ALSO .Xr nfsd 1M , .Xr share 1M , .Xr share_nfs 1M , .Xr sharectl 1M , .Xr showmount 1M , .Xr nfs 4 , .Xr sharetab 4 , .Xr attributes 5 .Sh NOTES Since .Nm must be running for .Nm nfsd to function properly, .Nm is automatically started by the .Sy svc:/network/nfs/server service. See .Xr nfs 4 .
p Some routines that compare hostnames use case-sensitive string comparisons; some do not. If an incoming request fails, verify that the case of the hostname in the file to be parsed matches the case of the hostname called for, and attempt the request again.
