rpc.idmapd — NFSv4 ID <-> Name Mapper


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


rpc.idmapd is the NFSv4 ID <-> name mapping daemon. It provides func‐
tionality 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 Increases the verbosity level (can be specified multiple

-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

-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.

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

Runs rpc.idmapd with the domain “citi.umich.edu” in the foreground,
printing all messages to console, and with a verbosity level of 3.
