SYNOPSIS

rpc.idmapd [-v ] [-f ] [-d domain ] [-p path ] [-U username ] [-G groupname ] [-c path ]

DESCRIPTION

rpc.idmapd is the NFSv4 ID <-> name mapping daemon. It provides functionality to the NFSv4 kernel client and server, to which it communicates via upcalls, by translating user and group IDs to names, and vice versa.

The options are as follows:

-v

-f

Runs rpc.idmapd in the foreground and prints all output to the terminal.

-d domain

Set domain to domain This is used internally by NFSv4 and is typically assigned by the system administrator. By default, domain is set to be the FQDN of the host, minus the hostname.

-p path

Specifies the location of the RPC pipefs to be path The default value is "/var/lib/nfs/rpc_pipefs".

-U username

Specifies the NFSv4 nobody user to be username The default value is "nobody".

-G groupname

Specifies the NFSv4 nobody group to be groupname The default value is "nobody".

-c path

Use configuration file path

-C

Client-only: perform no idmapping for any NFS server, even if one is detected.

-S

Server-only: perform no idmapping for any NFS client, even if one is detected.

EXAMPLES

rpc.idmapd -d citi.umich.edu -f -vvv
