NAME

6       nfs.conf - general configuration for NFS daemons and tools
7

SYNOPSIS

9       /etc/nfs.conf
10

DESCRIPTION

12       This  file contains site-specific configuration for various NFS daemons
13       and other processes.  Most configuration can also  be  passed  to  pro‐
14       cesses  via  command  line  arguments, but it can be more convenient to
15       have a central file.  In particular, this encourages consistent config‐
16       uration across different processes.
17
18       When  command  line  options  are provided, they override values set in
19       this file.  When this file does not specify a particular parameter, and
20       no  command line option is provided, each tool provides its own default
21       values.
22
23       The file format supports multiple sections, each of which  can  contain
24       multiple value assignments.  A section is introduced by a line contain‐
25       ing the section name enclosed in square brackets, so
26              [global]
27       would introduce a section called global.  A value assignment is a  sin‐
28       gle  line that has the name of the value, an equals sign, and a setting
29       for the value, so
30              threads = 4
31       would set the value named threads in the current section to 4.  Leading
32       and  trailing  spaces  and tab are ignored, as are spaces and tabs sur‐
33       rounding the equals sign.  Single and  double  quotes  surrounding  the
34       assigned value are also removed.  If the resulting string is empty, the
35       whole assignment is ignored.
36
37       Any line starting with “#” or “;” is ignored, as is any blank line.
38
39       If the assigned value started with a “$” then the remainder is  treated
40       as  a  name  and looked for in the section [environment] or in the pro‐
41       cesses environment (see environ(7)).  The value found is used for  this
42       value.
43
44       The value name include is special.  If a section contains
45              include = /some/file/name
46       then  the  named  file  will  be  read, and any value assignments found
47       there-in will be added to the current section.  If  the  file  contains
48       section  headers,  then  new  sections  will  be created just as if the
49       included file appeared in place of the include line.
50
51       Lookup of section and value names is case-insensitive.
52
53       Where a Boolean value is expected, any of true, t, yes, y, on, or 1 can
54       be  used  for  "true", while false, f, no, n, off, or 0 can be used for
55       "false".  Comparisons are case-insensitive.

SECTIONS

59       The following sections are known to various programs, and  can  contain
60       the  given named values.  Most sections can also contain a debug value,
61       which can be one or more from the list general, call, auth, parse, all.
62       When a list is given, the members should be comma-separated.
63
64       general
65              Recognized values: pipefs-directory.
66
67              See blkmapd(8), rpc.idmapd(8), and rpc.gssd(8) for details.
68
69
70       nfsdcltrack
71              Recognized values: storagedir.
72
73              The  nfsdcltrack program is run directly by the Linux kernel and
74              there is no opportunity to provide command  line  arguments,  so
75              the  configuration  file  is the only way to configure this pro‐
76              gram.  See nfsdcltrack(8) for details.
77
78
79       nfsd   Recognized values: threads, host, port, grace-time,  lease-time,
80              udp, tcp, vers2, vers3, vers4, vers4.0, vers4.1, vers4.2, rdma.
81
82              Version  and  protocol  values  are  Boolean values as described
83              above, and are also used by rpc.mountd.   Threads  and  the  two
84              times are integers.  port and rdma are service names or numbers.
85              See rpc.nfsd(8) for details.
86
87
88       mountd Recognized  values:  manage-gids,  descriptors,  port,  threads,
89              reverse-lookup, state-directory-path, ha-callout.
90
91              These,  together  with  the  protocol  and version values in the
92              [nfsd] section, are used to configure mountd.  See rpc.mountd(8)
93              for details.
94
95              The  state-directory-path  value in the [mountd] section is also
96              used by exportfs(8).
97
98
99       statd  Recognized values: port, outgoing-port,  name,  state-directory-
100              path, ha-callout.
101
102              See rpc.statd(8) for details.
103
104
105       lockd  Recognized values: port and udp-port.
106
107              See rpc.statd(8) for details.
108
109
110       sm-notify
111              Recognized values: retry-time, outgoing-port, and outgoing-addr.
112
113              See sm-notify(8) for details.
114
115
116       gssd   Recognized  values:  use-memcache,  use-machine-creds,  use-gss-
117              proxy,  avoid-dns,  limit-to-legacy-enctypes,   context-timeout,
118              rpc-timeout, keytab-file, cred-cache-directory, preferred-realm.
119
120              See rpc.gssd(8) for details.
121
122
123       exportfs
124              Only debug= is recognized.
