NAME
isdnd.rc -- isdn4bsd ISDN connection management daemon config file format
DESCRIPTION
The file /etc/isdn/isdnd.rc contains (if not otherwise specified on the command line) the runtime configuration for the isdnd(8) ISDN connection management daemon which is part of the isdn4bsd package. The configuration file consists of keywords which start in column 1 fol- lowed by one or more spaces or tabs, an equal sign, one or more spaces or tabs and a keyword dependent parameter value. A line beginning with '#' is treated as a comment line. For keywords requiring the specification of a boolean value, the truth value can be either yes or on while the false value can be either no or off. The configuration file consists of one system section, one or more optional controller sections and one or more entry sections. In the system section parameters regarding the daemon operation or parameters not associated with a single remote connection can be set. In the controller section parameters regarding a particular controller can be set. In the entry section(s) parameters directly associated with a sin- gle remote connection can be set. The following keywords are recognized by isdnd: system This keyword starts the system configuration section. It must not have a parameter and may be used only once. The keyword is mandatory. The following keywords are valid in the system con- figuration section: acctall If this parameter is set to on, accounting informa- tion is written even if the local site was not charged or no charging information is available or is not subscribed. (optional) acctfile Specifies the name of the accounting file which is used when the keyword useacctfile (see below) is set to on. See also system keyword rotatesuffix. If this keyword is omitted the system default is used. (optional) aliasing If this parameter is set to on, alias processing of telephone-number to name is enabled (see also the aliasfile keyword below). The default is off. (optional) aliasfile Specifies the name of the telephone number-to-name alias database file shared with the isdntel(8) util- ity when alias processing is enabled via the aliasing keyword. (optional) beepconnect In full-screen mode, if this parameter is set to on, ring the bell when connecting or disconnecting a call. extcallattr If this parameter is set to on, the extended caller attributes "screening indicator" and "presentation indicator" are written to the log-file. The default is off. (optional) holidayfile Specifies the name of the holiday file containing the dates of holidays. This file is used in con- junction with the valid keyword to lookup the dates of holidays. (optional) isdntime If this parameter is set to on, date/time informa- tion from the exchange (if provided) is written to the log-file. The default is off. (optional) mailer This keyword is used to specify the path/name of a mail program which which is able to use the "-s" flag to specify a subject on its command line. In case of a fatal error exit of isdnd.rc this program is used to send mail to an administrator specified by the keyword mailto. (optional) mailto This keyword is used to specify the email address of someone to notify in case of a fatal error exit of isdnd.rc. (See also keyword mailer). (optional) monitor-allowed If this parameter is set to on or yes, monitoring via a local or remote machine is enabled. This parameter is optional and is set to off by default. monitor-port sets the TCP port number for remote monitoring. This integer parameter is optional and is set to port 451 by default. monitor This keyword specifies a local socket name or a host or network for remote monitoring. The monitor spec- ification may either be: the name of a local (UNIX-domain) socket this MUST start with a "/", example: /var/run/isdn-monitor a dotted-quad host specification example: 192.168.1.2 a dotted-quad network address with netmask example: 192.168.1.0/24 a resolvable host name example: localhost a resolvable network name with netmask example: up-vision-net/24 monitor-access This keyword specifies the access rights for a pre- viously used monitor keyword. The supported access rights are: fullcmd restrictedcmd channelstate logevents callin callout ratesfile Specifies the name of the ratesfile. If this key- word is omitted the system default is used. (optional) regexpr This keyword is used to specify regular expressions. It can be specified more than once up to a compile time dependent value (currently set to 5 by the MAX_RE definition in the source). All specified regular expressions are compared to the log strings at runtime and if a match is found, a program is run with the log text as a parameter (see also the keyword regprog below). For an explanation how regular expressions are spec- ified, please have a look at re_format(7) and regex(3). The extended regular expression syntax is supported here. Hint: it might be necessary to properly quote the expression to avoid improper interpretation by the configuration file parser. (optional) regprog This keyword is used to specify the name of a pro- gram which is run in case a corresponding regular expression is matched by a logging string. Isdnd expects to find the program below the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional) rotatesuffix Specifies a suffix for renaming the log- and the accounting-filename. In case rotatesuffix is used and a USR1 signal is sent to isdnd, the log-file and the accounting file is not only closed and reopened but the old log-file is also renamed to the former filename with the rotatesuffix string appended. If this keyword is omitted, the log-files are just closed and reopened; this is also the default behav- ior. (optional) useacctfile If this parameter is set to on charging (if avail- able) and accounting information is written to the accounting file. (optional) controller This keyword starts the controller configuration section. It must not have a parameter and may be used once for every con- troller. The keyword is optional. The following keywords are valid in a controller configuration section: firmware This keyword is used to specify the path of the firmware file that will be loaded to the card once isdnd is started. This keyword is useful with active ISDN cards. protocol This keyword is used to set the D-channel protocol for the S0-bus a controller is connected to. The following parameters are currently supported: dss1 The DSS1 or so-called "Euro-ISDN" D- channel protocol according to ITU Recommendations Q.921 and Q.931. d64s An ISDN leased line with a single B- channel (called D64S in Germany). entry This keyword starts one configuration entry. It must not have a parameter. This keyword must be used at least once. The follow- ing keywords are valid in an entry section: answerprog This keyword is used to specify the name of a pro- gram which is run in case an incoming telephone connection specified answer in its configuration entry. The default name is answer. Isdnd expects to find this program beneath the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional) alert is used to specify a time in seconds to wait before accepting a call. This keyword is only usable for incoming telephone calls (dialin-reac- tion = answer). It is used to have a chance to accept an incoming call on the phone before the answering machine starts to run. The minimum value for the alert parameter is 5 seconds and the maximum parameter allowed is 180 seconds. (optional) autoupdown For network interfaces using ISDN as a transport medium it does not make sense to mark the inter- faces UP before running isdnd. Typically these interfaces are configured, but marked down, in the respective ifconfig.* file. When starting, isdnd recognizes these interfaces (configured with some address, marked down, and having a matching config entry) and marks them up. On shutdown, isdnd marks all interfaces changed at startup DOWN again. In rare circumstances you might not want this automatic handling. In this cases add an autoupdown=no line to the config file entry. b1protocol The B channel layer 1 protocol used for this con- nection. The keyword is mandatory. The currently configurable values are: hdlc HDLC framing. raw No framing at all (used for telephony). budget-calloutperiod is used to specify a time period in seconds. Within this period, the number of calls specified by budget-calloutncalls are allowed to succeed, any further attempt to call out will be blocked for the rest of the time left in the time period. (optional) budget-calloutncalls The number of outgoing calls allowed within the time period specified by budget-calloutperiod. (optional) budget-calloutsfile A path/filename to which the number of successful callouts are written. The contents of the file is preserved when it exists during startup of isdnd. The format of this file is: start time, last update time, number of calls. (optional) budget-calloutsfile-rotate If set to on rotate budget-calloutsfile every night when an attempt is made to update the file on a new day. The statistics for the previous day are written to a file with the filename specified by budget-calloutsfile to which a hyphen and the new day's (!) day of month number is appended. (optional) budget-callbackperiod budget-callbackncalls budget-callbacksfile budget-calloutsfile-rotate See budget-calloutperiod, budget-calloutncalls and budget-calloutsfile budget-calloutsfile-rotate above. These are used to specify the budgets for calling back a remote site. callbackwait The time in seconds to wait between hanging up the call from a remote site and calling back the remote site. (optional) calledbackwait The time in seconds to wait for a remote site calling back the local site after a call from the local site to the remote site has been made. (optional) connectprog specifies a program run every time after a connec- tion is established and address negotiation is complete (i.e.: the connection is usable). Isdnd expects to find the program below the path /etc/isdn which is prepended to the string speci- fied as a parameter to this keyword. The programs specified by connect and disconnect will get the following command line arguments: -d (device) -f (flag) [ -a (addr) ] where device is the name of device, e.g. "ippp0", flag will be "up" if connec- tion just got up, or "down" if interface changed to down state and addr the address that got assigned to the interface as a dotted-quad IP address (optional, only if it can be figured out by isdnd). (optional) dialin-reaction Used to specify what to do when an incoming con- nection request is received. The keyword is mandatory. The currently supported parameters are: accept Accept an incoming call. reject Reject an incoming call. ignore Ignore an incoming call. answer Start telephone answering for an incoming voice call. callback When a remote site calls, hang up and call back the remote site. dialout-type This keyword is used to configure what type of dialout mode is used. The keyword is mandatory. The currently supported parameters are: normal Normal behavior, call the remote site which is supposed to accept the call. calledback Callback behavior, call the remote side which rejects the call and calls us back. dialrandincr When dialing or re-dialing and this parameter is set to on, the dial retry time is added with a random value (currently 0...3 seconds) to minimize the chance of two sites dialing synchronously so each gets a busy each time it dials because the other side is also dialing. dialretries The number of dialing retries before giving up. Setting this to -1 gives an unlimited number of retries! (optional) direction This keyword is used to configure if incoming and outgoing, incoming-only or outgoing only connec- tions are possible. The keyword is optional, the default is inout. The currently supported parameters are: inout Normal behavior, connection establishment is possible from remote and local. in Only incoming connections are possible. out Only outgoing connections are possible. disconnectprog specifies a program run every time after a connec- tion was shut down. Isdnd expects to find the program below the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional) downtries is used to configure the number of unsuccessful tries (= retry cycles!) before the interface is disabled (for downtime seconds). (see also the keyword usedown further up). This keyword is optional. downtime is used to configure the time in seconds an inter- face is disabled after the configured number of downtries. (see also the keyword usedown further up). This keyword is optional and is set to 60 seconds by default. earlyhangup A (safety) time in seconds which specifies the time to hang up before an expected next charging unit will occur. (optional) idle-algorithm-outgoing The algorithm used to determine when to hang up an outgoing call when the line becomes idle. The current algorithms are: fix-unit-size idle algorithm which assumes fixed sized changing units during the whole call. var-unit-size idle algorithm which assumes that the charging is time based after the first units time has expired. idletime-outgoing The time in seconds an outgoing connection must be idle before hanging up. An idle timeout of zero disables this functionality. (optional) idletime-incoming The time in seconds an incoming connection must be idle before hanging up. An idle timeout of zero disables this functionality. (optional) isdncontroller The ISDN controller number to be used for connec- tions for this entry. (mandatory) isdnchannel The ISDN controller channel number to be used for connections for this entry. In case a channel is explicitly selected here, the SETUP message will request this channel but mark the request as preferred (the indicated channel is preferred) instead of exclusive (only the indicated channel is acceptable). Thus the exchange is still free to select another than the requested channel! (mandatory) isdntxdel-incoming How long to delay the transmission of the first packet after a successful connection is made for incoming ISDN connections. The specification unit is 1/100 second. A zero (0) disables this feature and is the default value. This feature is imple- mented (and makes sense only) for the irip(4) IP over raw HDLC ISDN driver. (optional) isdntxdel-outgoing How long to delay the transmission of the first packet after a successful connection is made for outgoing ISDN connections. The specification unit is 1/100 second. A zero (0) disables this feature and is the default value. This feature is imple- mented (and makes sense only) for the irip(4) IP over raw HDLC ISDN driver. (optional) local-phone-dialout The local telephone number used when the local site dials out. When dialing out to a remote site, the number specified here is put into the Calling Party Number Information Element. This keyword is mandatory for the irip user-land interfaces. local-phone-incoming The local telephone number used for verifying the destination of incoming calls. When a remote site dials in, this number is used to verify that it is the local site which the remote site wants to con- nect to. It is compared with the Called Party Number Information Element got from the telephone exchange. This keyword is mandatory for the irip interfaces. name Defines a symbolic name for this configuration entry. Its purpose is to use this name in the full-screen display for easy identification of a link to a remote site and for accounting purposes. (mandatory) ppp-auth-paranoid If set to no, the remote site is not required to prove its authenticity for connections that are initiated by the local site. The default is yes and requires the remote site to always authenti- cate. This keyword is only used if ppp-send-auth has been set to pap or chap for an ippp PPP interface. (optional) ppp-auth-rechallenge Set to no, if the other side does not support re- challenging for chap. The default is yes, which causes verification of the remote site's authen- ticity once in a while. This keyword is only used if ppp-expect-auth has been set to chap for an ippp PPP interface. (optional) ppp-expect-auth The local site expects the authenticity of the remote site to be proved by the specified method. The supported methods are: none Do not require the other side to authenti- cate. Typical uses are dial-out to an ISP (many ISPs do not authenticate themselves to clients) or offering anonymous dial-in at the local site. chap The preferred authentication method, which does not require a password to be sent in the clear. pap The unprotected authentication method, which allows anybody watching the wire to grab name and password. If ppp-auth-paranoid is set to no (the default is yes) outgoing connections will not require the remote site to authenticate itself. This keyword is only used for the ippp PPP inter- faces. (optional) ppp-expect-name The name that has to be provided by the remote site to prove its authenticity. This keyword is only used if ppp-expect-auth has been set to pap or chap for an ippp PPP interface. (optional) ppp-expect-password The secret that has to be provided by the remote site to prove its authenticity. This keyword is only used if ppp-expect-auth has been set to pap or chap for an ippp PPP interface. (optional) ppp-send-auth The authentication method required by the remote site. The currently supported parameters are: none The remote site does not expect or support authentication. chap The preferred authentication method, which does not require a password to be sent in the clear. pap The unprotected authentication method, which allows anybody watching the wire to grab name and password. This keyword is only used for the ippp PPP inter- faces. (optional) ppp-send-name The authentication name sent to the remote site. This keyword is only used if ppp-send-auth has been set to pap or chap for an ippp PPP interface. (optional) ppp-send-password The secret used to prove the local site's authen- ticity to the remote site. This keyword is only used if ppp-send-auth has been set to pap or chap for an ippp PPP interface. (optional) ratetype The rate entry used from the rates file. (optional) For example, ratetype=0 selects lines beginning "ra0" in /etc/isdn/isdnd.rates; (typically ra0 lines are a set of tables for local call rates on different days of the week & times per day). recoverytime The time in seconds to wait between dial retries. (optional) remdial-handling is used to specify the dialout behavior in case more than one outgoing number is specified. The currently supported parameters are: first For every new (non-retry) call setup, start with the first number. last For every new (non-retry) call setup, start with the last number with which a successful connection was made. next For every new (non-retry) call setup, start with the next number which follows the last one used. remote-phone-dialout The remote telephone number used when the local site dials out. When dialing out to a remote site, the number specified here is put into the Called Party Number Information Element. This keyword is mandatory for the irip interfaces. It may be specified more than once to try to dial to several numbers until one succeeds. remote-phone-incoming The remote telephone number used to verify an incoming call. When a remote site dials in, this number is used to verify that it is the correct remote site which is herewith authorized to con- nect into the local system. This parameter is compared against the Calling Party Number Information Element got from the telephone exchange. This keyword is mandatory for the irip interfaces. This keyword may have a wildcard parameter '*' to permit anyone dialing in. unitlength The length of a charging unit in seconds. This is used in conjunction with the idletime to decide when to hang up a connection. (optional) unitlengthsrc This keyword is used to specify from which source isdnd(8) takes the unitlength for short-hold mode. The currently configurable values are: none Then unitlength is not specified anywhere. cmdl Use the unitlength specified on the com- mand line. conf Use the unitlength specified in the con- figuration file with the keyword unitlength. rate Use the unitlength from the ratesfile specified in the configuration file with the keyword ratetype. aocd Use a dynamically calculated unitlength in case AOCD is subscribed on the ISDN line. (AOCD is an acronym for ``Advice Of Charge During the call'' which is a service pro- vided by the telecommunications (ie phone) provider, to indicate billable units). usrdevicename Specifies the user-land interface which is used for interfacing ISDN B channel data to the user- land. The keyword is mandatory. This keyword accepts the following parameters: irip This parameter configures a raw HDLC IP over ISDN interface. ippp This parameter configures a synchronous PPP over ISDN interface. rbch This specifies a Raw B Channel access interface. isdntel ISDN telephony. ing configures a ISDN B-channel to NetGraph interface. usrdeviceunit Specifies the unit number for the device which is specified with usrdevicename. usedown is used to enable the use of the keywords downtries and downtime in the entries section(s). It is used in the isdnd daemon to dynamically enable and disable the IP interfaces to avoid excessive dialing activities in case of transient failures (such as busy lines). This parameter is optional and is set to off by default. valid Note: this feature is considered experimental! The parameter to this keyword is a string specify- ing a time range within which this entry is valid. The time specification consists of a list of week- days and/or a holiday indicator ( see also the holidayfile keyword in the system section ) sepa- rated by commas followed by an optional daytime range specification in the form hh:mm-hh:mm. The weekdays are specified as numbers from 0 to 6 and the number 7 for holidays: 0 Sunday 1 Monday 2 Tuesday 3 Wednesday 4 Thursday 5 Friday 6 Saturday 7 a Holiday The following examples describe the "T-ISDN xxl" tariff of the german Telekom: 1,2,3,4,5,6,09:00-18:00 Monday through Saturday, daytime 9:00 to 18:00 1,2,3,4,5,6,18:00-9:00 Monday through Saturday, nighttime 18:00 to 9:00 0,7 Sunday and on holidays, all 24 hours The use of this keyword is optional.
IDLETIME CALCULATION AND SHORT-HOLD MODE
incoming calls It is assumed that the calling side knows most about charging structures and such and as a consequence only the keyword idletime-incoming has a function for incoming calls. For incoming calls the line is constantly monitored, and in case there was not traffic taking place for the time in seconds speci- fied by idletime-incoming the call is closed. Typically, idletime-incoming is used as a last resort and is therefore set much higher than a charging unit time: typical val- ues are one to five minutes. outgoing calls Outgoing call disconnect time can be set up in one of three ways: simple mode For simple mode, the idle-algorithm-outgoing must be fix-unit-size and the selected unitlength must be 0 (zero) and idletime-outgoing greater zero. The outgoing traffic is constantly monitored, and in case there was not traffic taking place for the time in sec- onds specified by idletime-outgoing the call is closed. Typical values in simple mode are 10 to 30 seconds. shorthold mode for fixed unit charging For shorthold mode, the idle-algorithm-outgoing must be fix-unit-size and the selected unitlength and idletime-outgoing must be greater than 0 (zero); earlyhangup must be >= 0 (zero). |<unchecked-window>|<checkwindow>|<safetywindow>| | | | | +------------------+-------------+--------------+ | | | | | |<-idle-time->|<earlyhangup->| |<--------------unitlength--------------------->| During the unchecked window which is (unitlength - (idle- time+earlyhangup)) in length, no idle check is done. After the unchecked window has ended, the line is checked for idle-time length if no traffic takes place. In case there was traffic detected in the check-window, the same procedure is restarted at the beginning of the next unit. In case no traffic was detected during the check-window, the line is closed at the end of the check window. Notice: unitlength must (!) be greater than the sum of idletime-outgoing and earlyhangup! shorthold mode for variable unit charging For shorthold mode, the idle-algorithm-outgoing must be var-unit-size and the selected unitlength and idletime-outgoing must be greater than 0 (zero); This shorthold mode is suitable when your calls are billed on the elapse time of the call plus a fixed con- nection charge. For example British Telecom bill this way. Each call is divided into two periods, the first is the unchecked period and the second is the checked. The checked period starts 1 second before the first units time expires. During the checked period if there is no traffic for idle-time seconds the call is disconnected. |<---unchecked------------------>|<------checked------> +------------------+-------------+ | |<-idle-time->| |<--------------unitlength------->| Experience shows that useful values for idle-time are from 15 to 30 seconds. If idle-time is too short an application that is not yet finished with the network will cause a new call to be placed.
