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 rpc.idmapd.  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.
