21 .SH DESCRIPTION
22 .sp
23 .LP
24 \fBinetd\fR is the delegated restarter for internet services for the Service
25 Management Facility (SMF). Its basic responsibilities are to manage service
26 states in response to administrative requests, system failures, and service
27 failures; and, when appropriate, to listen for network requests for services.
28 .sp
29 .LP
30 Services are no longer managed by editing the inetd configuration file,
31 \fBinetd.conf\fR(4). Instead, you use \fBinetconv\fR(1M) to convert the
32 configuration file content into SMF format services, then manage these services
33 using \fBinetadm\fR(1M) and \fBsvcadm\fR(1M). Once a service has been converted
34 by \fBinetconv\fR, any changes to the legacy data in the \fBinetd\fR config
35 file will not become effective. However, \fBinetd\fR does alert the
36 administrator when it notices change in the configuration file. See the start
37 description under the "inetd Methods" section for further information.
38 .sp
39 .LP
40 Also note that the current \fBinetd\fR cannot be run from outside the SMF. This
41 means it cannot be run from the command line, as was supported by the previous
42 \fBinetd\fR. If you attempt to do this, a message is sent to stderr displaying
43 mappings between the options supported by the previous \fBinetd\fR to the SMF
44 version of \fBinetd\fR.
45 .sp
46 .LP
47 \fBinetd\fR listens for connections on behalf of all services that are in
48 either the \fBonline\fR or \fBdegraded\fR state. A service enters one of these
49 states when the service is enabled by the user and \fBinetd\fR manages to
50 listen on its behalf. A listen attempt can fail if another server (whether
51 standalone or a third-party internet service) is already listening on the same
52 port. When this occurs, \fBinetd\fR logs this condition and continues trying to
53 bind to the port at configured intervals a configured number of times. See the
54 property \fBbind_fail_max\fR under "Service Properties," below, for more
55 details.
56 .sp
57 .LP
58 The configuration of all \fBinetd\fR's managed SMF services is read when it is
59 started. It is reread when \fBinetd\fR is refreshed, which occurs in response
60 to an SMF request, or when it receives a SIGHUP signal. See the \fBrefresh\fR
61 description under "inetd Methods" for the behavior on configuration refresh.
62 .sp
63 .LP
64 You can use the \fBinetadm\fR(1M) or \fBsvccfg\fR(1M) utilities to make
65 configuration changes to Internet services within the SMF repository.
66 \fBinetadm\fR has the advantage over \fBsvccfg\fR in that it provides an
67 Internet/RPC service context.
68 .SS "Service States"
69 .sp
70 .LP
71 As part of its service management duties, \fBinetd\fR implements a state
72 machine for each of its managed services. The states in this machine are made
73 up of the \fBsmf\fR(5) set of states. The semantics of these states are as
74 follows:
75 .sp
76 .ne 2

93 connections active.

97 .ne 2
98 .na
99 \fB\fBdegraded\fR\fR
100 .ad
101 .sp .6
102 .RS 4n
103 The service has entered this state because it was able to listen and process
104 requests for some, but not all, of the protocols specified for the service,
105 having exhausted its listen retries. Existing network connections might be
106 active.
107 .RE

116 Connections might be active, but no new requests are being handled. This is a
117 transient state. A service might be \fBoffline\fR for any of the following
118 reasons:
119 .RS +4
120 .TP
121 .ie t \(bu

123 The service's dependencies are unmet. When its dependencies become met the
124 service's state will be re-evaluated.
125 .RE

127 .TP
128 .ie t \(bu
129 .el o
130 The service has exceeded its configured connection rate limit,
131 \fBmax_con_rate\fR. The service's state is re-evaluated when its connection
132 offline timer, \fBcon_rate_offline\fR, expires.
133 .RE
134 .RS +4
135 .TP
136 .ie t \(bu

138 The service has reached its allowed number of active connections,
139 \fBmax_copies\fR. The service's state is re-evaluated when the number of active
140 connections drops below \fBmax_copies\fR.
141 .RE
142 .RS +4
143 .TP
144 .ie t \(bu

146 \fBinetd\fR failed to listen on behalf of the service on all its protocols. As
147 mentioned above, \fBinetd\fR retries up to a configured maximum number of
148 times, at configured intervals.The service's state is re-evaluated when either
149 a listen attempt is successful or the retry limit is reached.

170 .sp .6
171 .RS 4n
172 A service is in this state because it is either malfunctioning and needs
173 adminstrator attention or because an administrator has requested it.
174 .sp
175 Events constituting malfunctioning include: \fBinetd\fR's inability to listen
176 on behalf on any of the service's protocols before exceeding the service's bind
177 retry limit, non-start methods returning with non-success return values, and
178 the service exceeding its failure rate.
179 .sp
180 You request the maintenance state to perform maintenance on the service, such
181 as applying a patch. No new requests are handled in this state, but existing
182 connections might be active. Administrator intervention is required to exit
183 this state.

189 .SS "Service Methods"
190 .sp
191 .LP
192 As part of certain state transitions \fBinetd\fR will execute, if supplied, one
193 of a set of methods provided by the service. The set of supported methods are:

214 to the \fBoffline\fR state. For a \fBwait\fR-type service that at the time of
215 execution is performing its own listening, this method should result in it
216 ceasing listening. This method will be executed before the \fBdisable\fR method
217 in the case an \fBonline\fR/\fBdegraded\fR service is disabled. This method is
218 required to be implemented for a \fBwait\fR-type service.

375 the service being transitioned to the \fBmaintenance\fR state. This is
376 different from the behavior of the previous \fBinetd\fR, which continued to
377 retry every 10 minutes, indefinitely. The \fBfailrate_cnt\fR check accounts for
378 badly behaving servers that fail before consuming the service request and which
379 would otherwise be continually restarted, taxing system resources. Failure rate

593 with their seed values, are listed below. Note that these values are
594 configurable through \fBinetadm\fR(1M).

614 Each method specified for a service will have its configuration stored in the
615 SMF repository, within a property group of the same name as the method. The set
616 of properties allowable for these methods includes those specified for the
617 services managed by \fBsvc.startd\fR(1M). (See \fBsvc.startd\fR(1M) for further
618 details.) Additionally, for the \fBinetd_start\fR method, you can set the
619 \fBarg0\fR property.
620 .sp
621 .LP
622 The \fBarg0\fR property allows external wrapper programs to be used with
623 \fBinetd\fR services. Specifically, it allows the first argument,
624 \fBargv[0]\fR, of the service's start method to be something other than the
625 path of the server program.
626 .sp
627 .LP
628 In the case where you want to use an external wrapper program and pass
629 arguments to the service's daemon, the arguments should be incorporated as
630 arguments to the wrapper program in the \fBexec\fR property. For example:
631 .sp
632 .in +2
633 .nf
634 exec='/path/to/wrapper/prog service_daemon_args'
635 arg0='/path/to/service/daemon'

637 .in -2
639 .sp
640 .LP
641 In addition to the special method tokens mentioned in \fBsmf_method\fR(5),
642 \fBinetd\fR also supports the \fB:kill_process\fR token for \fBwait\fR-type
643 services. This results in behavior identical to that if the \fB:kill\fR token
644 were supplied, except that the \fBkill\fR signal is sent only to the parent
645 process of the \fBwait\fR-type service's \fBstart\fR method, not to all members
646 of its encompassing process contract (see \fBprocess\fR(4)).

854 The \fBinetd\fR daemon performs the same function as, but is implemented
855 significantly differently from, the daemon of the same name in Solaris 9 and
856 prior Solaris operating system releases. In the current Solaris release,
857 \fBinetd\fR is part of the Solaris Management Facility (see \fBsmf\fR(5)) and
858 will run only within that facility.

861 The \fB/etc/default/inetd\fR file has been deprecated. The functionality
862 represented by the properties \fBENABLE_CONNECTION_LOGGING\fR and
863 \fBENABLE_TCP_WRAPPERS\fR are now available as the \fBtcp_trace\fR and
864 \fBtcp_wrappers\fR properties, respectively. These properties are described
865 above, under "Service Properties".
