- X.SH DESCRIPTION
- X.B "xinetd.conf"
- Xis the configuration file that
- Xdetermines the services provided by \fBxinetd\fP.
- XAny line whose first non-white-space character is a '#' is considered
- Xa comment line. Empty lines are ignored.
- X.LP
- XThe file contains entries of the form:
- X.RS
- X.nf
- X.ft B
- X.sp
- Xservice <service_name>
- X{
- X.RS
- X.ft B
- X<attribute> <assign_op> <value> <value> ...

- X.LP
- XThe assignment operator,
- X.I assign_op,
- Xcan be one of
- X.B '=',
- X.B '+=',
- X.B '-='.
- XThe majority of attributes support only the simple assignment operator,
- X.B '='.
- XAttributes whose value is a set of values support all assignment operators.
- XFor such attributes,
- X.B '+='
- Xmeans adding a value to the set and
- X.B '-='
- Xmeans removing a value from the set.
- XA list of these attributes will be given
- Xafter all the attributes are described.
- X.LP
- XEach entry defines a service identified by the \fIservice_name\fP.
- XThe following is a list of available attributes:
- X.TP 17
- X.SB id
- XThis attribute is used to uniquely identify a service.
- XThis is useful because there exist services that can use different
- Xprotocols and need to be described with different entries in the
- Xconfiguration file.
- XBy default, the service id is the same as the service name.
- X.TP
- X.SB type
- XAny combination of the following values may be used:
- X.RS
- X.TP 12
- X.SB RPC
- Xif this is an RPC service
- X.TP
- X.SB INTERNAL
- Xif this is a service provided by \fBxinetd\fP.
- X.TP
- X.SB UNLISTED
- Xif this is a service not listed in a standard system file
- X(like
- X.I /etc/rpc
- Xfor RPC services, or
- X.I /etc/services
- Xfor non-RPC services).
- X.RE
- X.TP
- X.SB flags
- XAny combination of the following flags may be used:
- X.RS
- X.TP 12
- X.SB REUSE
- XSet the
- X.I SO_REUSEADDR
- Xflag on the service socket (check
- X.I "setsockopt(2)"
- Xfor more information).
- X.TP
- X.SB INTERCEPT
- XIntercept packets or accepted connections in order to verify that they
- Xare coming from acceptable locations (internal or multi-threaded
- Xservices cannot be intercepted).
- X.TP
- X.SB NORETRY
- XAvoid retry attempts in case of fork failure.
- X.TP
- X.SB IDONLY
- XAccept connections only when the remote end identifies the remote user
- X(i.e. the remote host must run an identification server).
- XThis flag applies only to connection-based services.
- XThis flag is ineffective if the
- X.B USERID
- Xlog option is not used.
- X.RE
- X.TP
- X.SB socket_type
- XPossible values for this attribute include:
- X.RS
- X.TP 12
- X.I stream
- Xstream-based service
- X.TP
- X.I dgram
- Xdatagram-based service
- X.TP
- X.I raw
- Xservice that requires direct access to IP
- X.TP
- X.I seqpacket
- Xservice that requires reliable sequential datagram transmission
- X.RE
- X.TP
- X.SB protocol
- Xdetermines the protocol that is employed by the service.
- XThe protocol must exist in
- X.I /etc/protocols.
- XIf this
- Xattribute is not defined, the default protocol employed by the service
- Xwill be used.
- X.TP
- X.SB wait
- XThis attribute determines if the service is single-threaded or
- Xmulti-threaded. If its value is \fIyes\fP the service is single-threaded;
- Xthis means that \fBxinetd\fP will start the server and then it will stop
- Xhandling requests for the service until the server dies.
- XIf the attribute value is \fIno\fP, the service is multi-threaded and
- X\fBxinetd\fP will keep handling new service requests.
- X.TP
- X.SB user
- Xdetermines the uid for the server process. The user name must exist in
- X.I /etc/passwd.
- XThis attribute is ineffective if the effective user ID
- Xof \fBxinetd\fP is not super-user.
- X.TP
- X.SB group
- Xdetermines the gid for the server process. The group name must exist in
- X.I /etc/group.
- XIf a group is not specified, the group
- Xof \fIuser\fP will be used (from
- X.I /etc/passwd).
- XThis attribute is ineffective if the effective user ID
- Xof \fBxinetd\fP is not super-user.
- X.TP
- X.SB instances
- Xdetermines the number of servers that can be simultaneously active
- Xfor a service (the default is no limit). The value of this
- Xattribute can be either a number or
- X.SB UNLIMITED
- Xwhich means that there is no limit.
- X.TP
- X.SB nice
- Xdetermines the server priority. Its value is a (possibly negative) number;
- Xcheck nice(3) for more information.
- X.TP
- X.SB server
- Xdetermines the program to execute for this service.
- X.TP
- X.SB server_args
- Xdetermines the arguments passed to the server. In contrast to \fBinetd\fP,
- Xthe server name should \fInot\fP be included in \fIserver_args\fP.
- X.TP
- X.SB only_from
- Xdetermines the remote hosts to which the particular
- Xservice is available.
- XIts value is a list of IP addresses which can be specified in any
- Xcombination of the following ways:
- X.RS
- X.TP 5
- X.SB a)
- Xa numeric address in the form of %d.%d.%d.%d. If the rightmost components are
- X0, they are treated as wildcards
- X(for example, 128.138.12.0 matches all hosts on the 128.138.12 subnet).
- X0.0.0.0 matches all Internet addresses.
- X.TP
- X.SB b)
- Xa factorized address in the form of %d.%d.%d.{%d,%d,...}.
- XThere is no need for all 4 components (i.e. %d.%d.{%d,%d,...%d} is also ok).
- XHowever, the factorized part must be at the end of the address.
- X.TP
- X.SB c)
- Xa network name (from
- X.I /etc/networks)
- X.TP
- X.SB d)
- Xa host name. All IP addresses of the specified host name will be used.
- X.RE
- X.TP
- X.SB ""
- XSpecifying this attribute
- Xwithout a value makes the service available to nobody.
- X.TP
- X.SB no_access
- Xdetermines the remote hosts to which the particular
- Xservice is unavailable. Its value can be specified in the same way as the
- Xvalue of the \fBonly_from\fP
- Xattribute. These two attributes determine the location access control
- Xenforced by \fBxinetd\fP. If none of the two is specified for a service,
- Xthe service is available to anyone. If both are specified for a service,
- Xthe one that is the better match for
- Xthe address of the remote host determines
- Xif the service is available to that host (for example, if the
- X\fBonly_from\fP list contains 128.138.209.0 and the
- X\fBno_access\fP list contains 128.138.209.10
- Xthen the host with the address 128.138.209.10 can not access the service).
- X.TP
- X.SB access_times
- Xdetermines the time intervals when the service is available. An interval
- Xhas the form \fIhour:min-hour:min\fP (connections
- X.I will
- Xbe accepted at the bounds of an interval). Hours can range from 0 to 23 and
- Xminutes from 0 to 59.
- X.TP
- X.SB log_type
- Xdetermines where the service log output is sent. There are two formats:
- X.RS
- X.TP
- X.SB SYSLOG " \fIsyslog_facility [syslog_level]\fP"
- XThe log output is sent to syslog at the specified facility. Possible facility
- Xnames include:
- X.I daemon,
- X.I auth,
- X.I user,
- X.I "local0-7."
- XPossible level names include:
- X.I emerg,
- X.I alert,
- X.I crit,
- X.I err,
- X.I warning,
- X.I notice,
- X.I info,
- X.I debug.
- XIf a level is not present, the messages will be recorded at the
- X.I info
- Xlevel.
- X.TP
- X.SB FILE " \fIfile [soft_limit [hard_limit]]\fP"
- XThe log output is appended to \fIfile\fP which will be created if it does
- Xnot exist. Two limits on the size of the log file can be optionally specified.
- XThe first limit is a soft one;
- X.B xinetd
- Xwill log a message the first time this limit is exceeded (if
- X.B xinetd
- Xlogs to syslog, the message will be sent at the
- X.I alert
- Xpriority level).
- XThe second limit is a hard limit;
- X.B xinetd
- Xwill stop logging for the affected service (if the log file is a
- Xcommon log file, then more than one service may be affected)
- Xand will log a message about this (if
- X.B xinetd
- Xlogs to syslog, the message will be sent at the
- X.I alert
- Xpriority level).
- XIf a hard limit is not specified, it defaults to the soft limit
- Xincreased by 1% but the extra size must be within the parameters
- X.SM LOG_EXTRA_MIN
- Xand
- X.SM LOG_EXTRA_MAX
- Xwhich default to 5K and 20K respectively (these constants are defined in
- X\fIconfig.h\fP).
- X.RE
- X.TP
- X.SB log_on_success
- Xdetermines what information is logged when a server is started and when
- Xthat server exits (the service id is always included in the log entry).
- XAny combination of the following values may be specified:
- X.RS
- X.TP 12
- X.SB PID
- Xlogs the server process id (if the service is implemented by \fBxinetd\fP
- Xwithout forking another process the logged process id will be 0)
- X.TP
- X.SB HOST
- Xlogs the remote host address
- X.TP
- X.SB USERID
- Xlogs the user id of the remote user using the RFC 1413 identification protocol.
- XThis option is available only for multi-threaded stream services.
- X.TP
- X.SB EXIT
- Xlogs the fact that a server exited along with the exit status or the
- Xtermination signal
- X(the process id is also logged if the
- X.SB PID
- Xoption is used)
- X.TP
- X.SB DURATION
- Xlogs the duration of a service session
- X.RE
- X.TP
- X.SB log_on_failure
- Xdetermines what information is logged when a server cannot be started
- X(either because of a lack of resources or because of access control
- Xrestrictions). The service id is always included in the log entry along
- Xwith the reason for failure.
- XAny combination of the following values may be specified:
- X.RS
- X.TP 12
- X.SB HOST
- Xlogs the remote host address.
- X.TP
- X.SB USERID
- Xlogs the user id of the remote user using the RFC 1413 identification protocol.
- XThis option is available only for multi-threaded stream services.
- X.TP
- X.SB ATTEMPT
- Xlogs the fact that a failed attempt was made
- X(this option is implied by all others).
- X.TP
- X.SB RECORD
- Xrecords information from the remote end in case the server could not
- Xbe started. This allows monitoring of attempts to use the service.
- XFor example, the login service logs the local user, remote
- Xuser and terminal type.
- XCurrently, the services that support this option are:
- X.I login,
- X.I shell,
- X.I exec,
- X.I finger.
- X.RE
- X.TP
- X.SB rpc_version
- Xdetermines the RPC version for a RPC service. The version can be
- Xa single number or a range in the form \fInumber\fP-\fInumber\fP.
- X.TP
- X.SB rpc_number
- Xdetermines the number for an
- X.I UNLISTED
- XRPC service (this attribute is ignored if the service is not unlisted).
- X.TP
- X.SB env
- XThe value of this attribute is a list of strings of the form 'name=value'.
- XThese strings will be added to the environment before
- Xstarting a server (therefore the server's environment will include
- X\fBxinetd\fP's environment plus the specified strings).
- X.TP
- X.SB passenv
- XThe value of this attribute is a list of environment variables from
- X\fBxinetd\fP's environment that will be passed to the server.
- XAn empty list implies passing no variables to the server
- Xexcept for those explicitly defined using the
- X.I env
- Xattribute.
- X(notice that you can use this attribute in conjuction with the
- X.I env
- Xattribute to specify exactly what argument will be passed to the server).
- X.TP
- X.SB port
- Xdetermines the service port. If this attribute is specified for a service
- Xlisted in
- X.I /etc/services,
- Xit must be equal to the port number listed in that file.
- X.LP
- XYou don't need to specify all of the above attributes for each service.

- X.\" *********************** INTERNAL SERVICES ****************************
- X.SH "INTERNAL SERVICES"
- X.LP
- X\fBxinetd\fP provides the following services internally (both
- Xstream and datagram based):
- X.I echo,
- X.I time,
- X.I daytime,
- X.I chargen,
- Xand
- X.I discard.
- XThese services are under the same access restrictions as all other
- Xservices except for the ones that don't require \fBxinetd\fP to fork
- Xanother process for them. Those ones (\fItime\fP, \fIdaytime\fP,
- Xand the datagram-based \fIecho\fP, \fIchargen\fP, and \fIdiscard\fP)
- Xhave no limitation in the number of
- X.B instances.
- X.LP
- X.B xinetd
- Xalso provides two
- X.I UNLISTED
- Xinternal stream-based services:
- X.I servers
- Xand
- X.I services.
- XThe former lists information about running servers while the latter
- Xprovides a list of currently active services.
- XThere is one service per line and each line contains the service name,
- Xprotocol (e.g. "tcp") and port number.
- X.\" *********************** NOTES ****************************
- X.SH NOTES
- X.IP 1. 4
- XThe following service attributes \fIcannot\fP be changed on reconfiguration:
- X.B socket_type,
- X.B wait,
- X.B protocol,
- X.B type.
- X.IP 2.
- XWhen the attributes
- X.I only_from
- Xand
- X.I no_access
- Xare not specified for a service (either directly or via \fIdefaults\fP)
- Xthe address check is considered successful (i.e. access will not be
- Xdenied).
- X.IP 3.
- XThe address check is based on the IP address of the remote host and
- Xnot on its domain address. We do this so that we can avoid
- Xremote name lookups which may take a long time (since
- X.B xinetd
- Xis single-threaded, a name lookup will prevent the daemon from
- Xaccepting any other requests until the lookup is resolved).
- XThe down side of this scheme is that if the IP address of a remote
- Xhost changes, then access to that host may be denied until
- X.B xinetd
- Xis reconfigured.
- XWhether access is actually denied or not will depend on whether the
- Xnew host IP address is among those allowed access. For example, if
- Xthe IP address of a host changes from 1.2.3.4 to 1.2.3.5 and
- Xonly_from is specified as 1.2.3.0 then access will not be denied.
- X.IP 4.
- XIf the
- X.SB USERID
- Xlog option is specified and the remote host either does not run an
- Xidentification server or the server sends back a bad reply,
- Xaccess will not be denied unless the
- X.I IDONLY
- Xservice flag is used.
- X.IP 5.
- XInterception works by forking a process which acts as a filter
- Xbetween the remote host(s) and the local server.
- XThis obviously has a performance impact so
- Xit is up to you to make the compromise between security and performance
- Xfor each service.
- XThe following tables show the overhead of interception.
- XThe first table shows the time overhead-per-datagram for a UDP-based service
- Xusing various datagram sizes.
- XFor TCP-based services we measured the bandwidth reduction
- Xbecause of interception while sending
- Xa certain amount of data from client to server (the time overhead should
- Xthe same as for UDP-based services but it is "paid" only by the first
- Xpacket of a continuous data transmission).
- XThe amount of data is given
- Xin the table as \fIsystem_calls\fPx\fIdata_sent_per_call\fP, i.e.
- Xeach
- X.I "send(2)"
- Xsystem call transferred so many bytes of data.
- XThe bandwidth reduction is given in terms of bytes per second and as
- Xa percentage of the bandwidth when interception is not performed.
- XAll measurements were done on a SparcStation IPC running SunOS 4.1.
