nfsrevoke -- revoke NFS V4 client SYNOPSIS
nfsrevoke ClientId DESCRIPTION
nfsrevoke This command is used by a system administrator to revoke a client's access to the NFS Version 4 server. All Open/Lock state held by the client will be released. After revocation, the client will no longer be able to use state on the server until it does a fresh SetClien- tID/SetClientIDConfirm operations sequence. THIS SHOULD BE DONE AS A LAST RESORT ONLY, when clients are holding state that must be released on the server. The ClientId argument is a hexadecimal string, which is the last field of the nfsdumpstate(8) command's -o and -l options output. SEE ALSO
nfsv4(4), nfsdumpstate(8) HISTORY
The nfsrevoke command was introduced as a part of the experimental nfs server subsystem. BSD

NFSCBD(8)						    BSD System Manager's Manual 						 NFSCBD(8)

nfscbd -- NFSv4 client side callback daemon SYNOPSIS
nfscbd [-p port_number] [-P client_principal] DESCRIPTION
nfscbd runs on a client using NFSv4 to handle callback requests from the NFSv4 server. If no nfscbd is running, NFSv4 mounts will still work, but the server will never issue Open Delegations to the client. One callback server and one master server are always started. The following options are available: -p port_number Specifies what port# the callback server should use. -P client_principal Specifies the host based principal name to be used as the target for callbacks over RPCSEC_GSS. For KerberosV, it must be in the client's default keytab file. This client_principal should be the same one specified by the gssname argument being used by nfsv4 mounts. If you do not specify this argument, callbacks will still work over AUTH_SYS, which is what many extant servers use even for RPCSEC_GSS mounts, as of 2009. For example, ``nfscbd -p 7654 -P root'' starts the daemon to handle callbacks on port# 7654 and is using the host based principal root@<client-host>.<dns-domain> as the callback target. nfscbd listens for service requests at the port defined by NFSV4_CBPORT in /usr/include/fs/nfs/nfs.h, unless -p has been specified. For more information on what callbacks and Open Delegations do, see Network File System (NFS) Version 4 Protocol, RFC3530. EXIT STATUS
The nfscbd utility exits 0 on success, and >0 if an error occurs. SEE ALSO
nfsv4(4), mount_nfs(8) HISTORY
First introduced with the experimental nfs client for NFSv4 support in 2009. BSD
