NAME

4     rpc.idmapd — NFSv4 ID <-> Name Mapper
5

SYNOPSIS

7     rpc.idmapd [-h] [-f] [-v] [-C] [-S] [-p path] [-c path]
8

DESCRIPTION

10     rpc.idmapd is the NFSv4 ID <-> name mapping daemon.  It provides func‐
11     tionality to the NFSv4 kernel client and server, to which it communicates
12     via upcalls, by translating user and group IDs to names, and vice versa.
13
14     Note that on more recent kernels only the NFSv4 server uses rpc.idmapd.
15     The NFSv4 client instead uses nfsidmap(8), and only falls back to
16     rpc.idmapd if there was a problem running the nfsidmap(8) program.
17
18     The options are as follows:
19
20     -h           Display usage message.
21
22     -v           Increases the verbosity level (can be specified multiple
23                  times).
24
25     -f           Runs rpc.idmapd in the foreground and prints all output to
26                  the terminal.
27
28     -p path      Specifies the location of the RPC pipefs to be path.  The
29                  default value is "/var/lib/nfs/rpc_pipefs".
30
31     -c path      Use configuration file path.  This option is deprecated.
32
33     -C           Client-only: perform no idmapping for any NFS server, even
34                  if one is detected.
35
36     -S           Server-only: perform no idmapping for any NFS client, even
37                  if one is detected.
