16 !!SYNOPSIS

18
19 __/sbin/rpc.statd [[-F] [[-d] [[-?] [[-n name ] [[-o port ] [[-p
20 port ] [[-V]__
21 !!DESCRIPTION
22
23
24 The __rpc.statd__ server implements the NSM (Network
25 Status Monitor) RPC protocol. This service is somewhat
26 misnomed, since it doesn't actually provide active
27 monitoring as one might suspect; instead, NSM implements a
28 reboot notification service. It is used by the NFS file
29 locking service, __rpc.lockd__, to implement lock
30 recovery when the NFS server machine crashes and
31 reboots.
32
33
34 __Operation__
35
36
37 For each NFS client or server machine to be monitored,
38 __rpc.statd__ creates a file in __/var/lib/nfs/sm__.
39 When starting, it iterates through these files and notifies
40 the peer __rpc.statd__ on those machines.
41 !!OPTIONS
42
43
44 __-F__
45
46
47 By default, __rpc.statd__ forks and puts itself in the
48 background when started. The __-F__ argument tells it to
49 remain in the foreground. This option is mainly for
50 debugging purposes.
51
52
53 __-d__
54
55
56 By default, __rpc.statd__ sends logging messages via
57 syslog(3) to system log. The __-d__ argument
58 forces it to log verbose output to __stderr__ instead.
59 This option is mainly for debugging purposes, and may only
60 be used in conjunction with the __-F__
61 parameter.
62
63
64 __-n, --name__ ''name''
65
66
67 specify a name for __rpc.statd__ to use as the local
68 hostname. By default, __rpc.statd__ will call
69 gethostname(2) to get the local hostname. Specifying
70 a local hostname may be useful for machines with more than
71 one interfaces.
72
73
74 __-o, --outgoing-port__ ''port''
75
76
77 specify a port for __rpc.statd__ to send outgoing status
78 requests from. By default, __rpc.statd__ will ask
79 portmap(8) to assign it a port number. As of this
80 writing, there is not a standard port number that
81 __portmap__ always or usually assigns. Specifying a port
82 may be useful when implementing a firewall.
83
84
85 __-p, --port__ ''port''
86
87
88 specify a port for __rpc.statd__ to listen on. By
89 default, __rpc.statd__ will ask portmap(8) to
90 assign it a port number. As of this writing, there is not a
91 standard port number that __portmap__ always or usually
92 assigns. Specifying a port may be useful when implementing a
93 firewall.
94
95
96 __-?__
97
98
99 Causes __rpc.statd__ to print out command-line help and
100 exit.
101
102
103 __-V__
104
105
106 Causes __rpc.statd__ to print out version information and
107 exit.
108 !!TCP_WRAPPERS SUPPORT
109
110
111 This __rpc.statd__ version is protected by the
112 __tcp_wrapper__ library. You have to give the clients
113 access to __rpc.statd__ if they should be allowed to use
114 it. To allow connects from clients of the .bar.com domain
115 you could use the following line in
116 /etc/hosts.allow:
117
118
119 statd: .bar.com
120
121
122 You have to use the daemon name __statd__ for the daemon
123 name (even if the binary has a different name).
