NAME

rpc.idmapd - NFSv4 ID <-> Name Mapper  

SYNOPSIS

rpc.idmapd [-h ] [-f ] [-v ] [-C ] [-S ] [-p path ] [-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.

Note that on more recent kernels only the NFSv4 server uses . The NFSv4 client instead uses nfsidmap(8), and only falls back to rpc.idmapd if there was a problem running the nfsidmap(8) program.

The options are as follows:

-h
Display usage message.
-v
Increases the verbosity level (can be specified multiple times).
-f
Runs rpc.idmapd in the foreground and prints all output to the terminal.
-p path
Specifies the location of the RPC pipefs to be path The default value is "/var/lib/nfs/rpc_pipefs".
-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 -f -vvv

Runs rpc.idmapd printing all messages to console, and with a verbosity level of 3.
