NAME

     rpc.idmapd — NFSv4 ID <-> Name Mapper

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           Increases the verbosity level (can be specified multiple times).

     -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

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