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

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

114 Connections might be active, but no new requests are being handled. This is a
115 transient state. A service might be \fBoffline\fR for any of the following
116 reasons:
117 .RS +4
118 .TP
119 .ie t \(bu
120 .el o
121 The service's dependencies are unmet. When its dependencies become met the
122 service's state will be re-evaluated.
123 .RE
124 .RS +4
125 .TP
126 .ie t \(bu
127 .el o
128 The service has exceeded its configured connection rate limit,
129 \fBmax_con_rate\fR. The service's state is re-evaluated when its connection
130 offline timer, \fBcon_rate_offline\fR, expires.
131 .RE
132 .RS +4
133 .TP
134 .ie t \(bu
135 .el o
136 The service has reached its allowed number of active connections,
137 \fBmax_copies\fR. The service's state is re-evaluated when the number of active
138 connections drops below \fBmax_copies\fR.
139 .RE
140 .RS +4
141 .TP
142 .ie t \(bu
143 .el o
144 \fBinetd\fR failed to listen on behalf of the service on all its protocols. As
145 mentioned above, \fBinetd\fR retries up to a configured maximum number of
146 times, at configured intervals.The service's state is re-evaluated when either
147 a listen attempt is successful or the retry limit is reached.

159 connections, and has none active. Administrator intervention is required to
160 exit this state.
161 .RE

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

186 Use \fBinetadm\fR(1M) to obtain the current state of a managed service.
187 .SS "Service Methods"
188 .LP
189 As part of certain state transitions \fBinetd\fR will execute, if supplied, one
190 of a set of methods provided by the service. The set of supported methods are:

198 Executed to handle a request for an \fBonline\fR or \fBdegraded\fR service.

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

274 Configuration for SMF-managed services is stored in the SMF repository. The
275 configuration is made up of the basic configuration of a service, the

319 associated port before giving up. The value \fB-1\fR specifies that no retry
320 limit is imposed. If none of the service's protocols were bound to before any
321 imposed limit is reached, the service goes to the \fBmaintenance\fR state;

369 applies to \fBwait\fR-type services and is reached when \fIcount\fR instances
370 of the service are started within a given time. Exceeding the rate results in
371 the service being transitioned to the \fBmaintenance\fR state. This is
372 different from the behavior of the previous \fBinetd\fR, which continued to
373 retry every 10 minutes, indefinitely. The \fBfailrate_cnt\fR check accounts for
374 badly behaving servers that fail before consuming the service request and which
375 would otherwise be continually restarted, taxing system resources. Failure rate
376 is equivalent to the \fB-r\fR option of the previous \fBinetd\fR. The values

590 configurable through \fBinetadm\fR(1M).

610 Each method specified for a service will have its configuration stored in the
611 SMF repository, within a property group of the same name as the method. The set
612 of properties allowable for these methods includes those specified for the
613 services managed by \fBsvc.startd\fR(1M). (See \fBsvc.startd\fR(1M) for further
614 details.) Additionally, for the \fBinetd_start\fR method, you can set the
615 \fBarg0\fR property.
616 .sp
617 .LP
618 The \fBarg0\fR property allows external wrapper programs to be used with
619 \fBinetd\fR services. Specifically, it allows the first argument,
620 \fBargv[0]\fR, of the service's start method to be something other than the
621 path of the server program.
622 .sp
623 .LP
624 In the case where you want to use an external wrapper program and pass
625 arguments to the service's daemon, the arguments should be incorporated as
626 arguments to the wrapper program in the \fBexec\fR property. For example:
627 .sp
628 .in +2
629 .nf
630 exec='/path/to/wrapper/prog service_daemon_args'
631 arg0='/path/to/service/daemon'
632 .fi
633 .in -2
635 .sp
636 .LP
637 In addition to the special method tokens mentioned in \fBsmf_method\fR(5),
638 \fBinetd\fR also supports the \fB:kill_process\fR token for \fBwait\fR-type
639 services. This results in behavior identical to that if the \fB:kill\fR token
640 were supplied, except that the \fBkill\fR signal is sent only to the parent
641 process of the \fBwait\fR-type service's \fBstart\fR method, not to all members
642 of its encompassing process contract (see \fBprocess\fR(4)).
643 .SS "Configuring Protocols for Sockets-Based Services"
644 .LP
645 When configuring \fBinetd\fR for a sockets-based service, you have the choice,
646 depending on what is supported by the service, of the alternatives described
647 under the \fBproto\fR property, above. The following are guidelines for which
648 \fBproto\fR values to use:

678 \fBudp6only\fR.

698 requests for those services that are in either the \fBonline\fR or
699 \fBdegraded\fR state.

701 In addition, \fBinetd\fR also checks if the \fBinetd.conf\fR(4)-format
702 configuration file it is monitoring has changed since the last
703 \fBinetconv\fR(1M) conversion was carried out. If it has, then a message

746 .RE
747 .RS +4
748 .TP
749 .ie t \(bu
750 .el o
751 if it is in the \fBonline\fR or \fBdegraded\fR state and the configuration has
752 changed such that a re-binding is necessary to conform to it, then the service
753 will be transitioned to the \fBoffline\fR state and back again, using the new

757 .TP
758 .ie t \(bu
759 .el o
760 if it is in the \fBonline\fR state and a re-binding is not necessary, then the

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

850 The \fB/etc/default/inetd\fR file has been deprecated. The functionality
851 represented by the properties \fBENABLE_CONNECTION_LOGGING\fR and
852 \fBENABLE_TCP_WRAPPERS\fR are now available as the \fBtcp_trace\fR and
853 \fBtcp_wrappers\fR properties, respectively. These properties are described
854 above, under "Service Properties".
