NAME

mountd- Server for NFS mount requests and NFS access checks

SYNOPSIS

/usr/lib/nfs/mountd [-v] [-r]

DESCRIPTION

mountd is an RPC server that answers requests for NFS access information and file system mount requests. It reads the file /etc/dfs/sharetab to determine which file systems are available for mounting by which remote machines. See sharetab(4). nfsd running on the local server will contact mountd 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 share_nfs(1M).

The command also provides information as to what file systems are mounted by which clients. This information can be printed using the showmount(1M) command.

The mountd daemon is automatically invoked in run level 3.

The sys_nfs, sys_devices, sys_net_config, sys_audit, net_mac_read, net_privaddr, file_mac_read, file_mac_write, file_mac_search, file_dac_search, proc_setsl, and proc_setclr privileges are required to run this daemon. This daemon must be started from the Trusted Path; otherwise, the daemon sets its sensitivity label to ADMIN_LOW and clearance to ADMIN_HIGH.

OPTIONS

-v

Run the command in verbose mode. Each time mountd determines what access a client should get, it will log the result to the console, as well as how it got that result.

-r

Reject mount requests from clients. Clients that have file systems mounted will not be affected.

SUMMARY OF TRUSTED SOLARIS CHANGES

The sys_nfs, sys_devices, sys_net_config, sys_audit, net_mac_read, net_privaddr, file_mac_read, file_mac_search, file_dac_search, proc_setsl, and proc_setclr privileges are required to run this daemon. This daemon must be started from the Trusted Path. If not started at a sensitivity label of ADMIN_LOW and clearance of ADMIN_HIGH, mountd sets its sensitivity label and clearance to these values.

For the mount request to succeed, this daemon requires the client to have the sys_mount privilege. Unless the -n option is specified, the client request must bind to a privileged port.

NOTES

If nfsd is running, mountd must also be running in order to be assured that the NFS server can respond to requests, otherwise, the NFS service can hang.

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.
