NAME
isdnctrl - get/set ISDN device information
SYNOPSIS
isdnctrl action device ...
DESCRIPTION
isdnctrl is used to create and delete network interfaces for ISDN, set up the vari-
ous parameters and phone numbers for dial in and dial out. It is also used to list
the current parameters of an already configured network interface. isdnctrl is not
needed for configuration of ISDN ttys!
The use of isdnctrl is independent of the hardware driver.
OPTIONS
The following actions may be given to isdnctrl.
addif name
Adds a new ISDN interface name to the kernel. If name is omitted, the kernel
will use ethX, where X is an increasing number starting from 0. This is
probably not useful with ISDN so using a name like isdn0 (for raw ip inter-
faces) or ippp0 (for synchronous PPP interfaces) is always recommended.
delif name [force]
Removes the ISDN interface name from the kernel. If the optional keyword
force is appended, isdnctrl executes ifconfig name down before removing it.
reset [force]
Removes all ISDN interfaces from the kernel if it is possible. If the
optional keyword force is appended, isdnctrl executes ifconfig name down
before removing an interface.
ifdefaults name
resets the interface name to some reasonable defaults.
dialmode name [off|manual|auto]
Sets the dial mode of the interface to one of:
off
no connection can be made; an existing connection is terminated immediately.
Incoming connections are also not possible.
manual
manual dialing / hangup; a connection will only be made after isdnctrl dial
name but the line will be disconnected after the huptimeout value set if
using kernel drivers updated since 1 Nov 1998; otherwise an explicit isdnc-
trl hangup name will be needed to cause the connection to be dropped.
Incoming connections are possible; however, if this interface is configured
in callback in mode, the callback dial will not happen (as this is actually
an outgoing connection, not an incoming one).
auto
autodial mode; an outgoing packet will trigger a dialout, and a hangup will
occur after the huptimeout value specified (see below).
An interface in auto dial mode will call another system back (if configured
in callback in mode).
auto was the "old" behaviour (as it was before dialmode was implemented).
If no argument is given, the current dialmode value is displayed.
You can give all as the interface name; the command will then be executed
for all interfaces.
addphone name out num
Adds the phone number num to the list of outgoing numbers of the ISDN inter-
face name. Numbers in this list are used to dial the remote station if the
connection is down and packets are to be sent via the interface (Dial on
demand). More than one number can be set by calling isdnctrl addphone
repeatedly. If more than one number is set, these will be tried one after
another (the last added number is tried first, etc.). When using a german
SPV-type connection, the number has to be prefixed by a capital S.
addphone name in num
Adds the phone number num to the list of incoming numbers of the ISDN inter-
face name. Numbers in this list are used to verify access permission of the
remote station if an incoming call is received. The verification can be dis-
abled by setting the interface into insecure mode using isdnctrl name secure
off. If the list is empty, incoming calls are disabled. More than one num-
ber can be added by calling isdnctrl addphone repeatedly. Also wildcards can
be used (see below).
delphone name in|out num
Removes phone number num from the incoming or outgoing phone list.
eaz name [num]
Set the EAZ (German 1TR6 protocol) or MSN (Euro-ISDN E-DSS1) for ISDN inter-
face name to num. For an EAZ this is only one digit, while for an MSN num
is the whole MSN (usually the local phone number). If num is omitted, isdnc-
trl prints the current setting for ISDN interface name.
huptimeout name [seconds]
Set the hangup timeout for ISDN interface name to seconds. If there is
inactivity (i.e. no traffic on the interface) for the given time the driver
automatically shuts down the connection. If seconds is omitted isdnctrl
prints the current setting for interface name.
cbdelay name [seconds]
Set the callback delay for ISDN interface name to seconds. If callback mode
for this interface is in, dialing is delayed the given time. If the callback
mode is out, after dialing out and waiting the given time, a hangup is
issued to free the line for the incoming callback from the remote machine.
This hangup-after-dial is disabled by setting cbdelay to 0. If seconds is
omitted isdnctrl prints the current setting for interface name.
dialmax name [num]
Set the number of dial attempts for ISDN interface name to num. If dialing,
each phone number is tried this many times before giving up. If num is
omitted isdnctrl prints the current setting for interface name.
ihup name [on|off]
Turn on or off the hangup timeout for incoming calls on interface name. If
on or off is omitted the current setting is printed.
chargehup name [on|off]
Turn on or off hangup before next charge info for interface name. This can
only be used if the ISDN provider transmits charge info during and after the
connection. If set to on, the driver will close the connection just before
the next charge info will be received if the interface is inactive. If on or
off is omitted the current setting is printed.
chargeint name [seconds]
If seconds are given, the charge interval for the given interface is set.
This may be useful on ISDN lines with no chargeinfo or no online chargeinfo.
The connection will be closed 2 seconds before the end of the next estimated
charge interval if huptimeout seconds of inactivity have been reached. If
ihup is on, incoming connections are closed by this mechanism also. On
lines with online charge info you also might ask by chargeint name for the
current charge interval as delivered from the telecom on a given interface.
secure name [on|off]
Turns on or off the security feature for interface name. If set to on,
incoming calls will only be accepted if the calling number can be found in
the incoming access list. See description of action addphone for information
about how to add numbers to this list. If on or off is omitted, the current
setting is printed.
callback name [mode]
Set callback mode for interface name to mode mode. If callback mode is in,
then after getting an incoming call, a callback is triggered. If callback
mode is out, then the local system does the initial call and then waits for
callback of the remote machine. The option on is available only for compati-
bility with older versions. Its meaning is the same like in. If callback
mode is off, calls are handled normally without special processing.
cbhup name [on|off]
Turns on or off Hangup (Reject) for interface name before starting callback.
If cbhup is on, when receiving an incoming call, the interface first rejects
that call before the callback sequence is started. If on or off is omitted,
the current setting is printed.
encap name [encapsulation]
Set the encapsulation mode for interface name. Possible encapsulations are:
rawip
raw ip encapsulation (default)
ip
IP + typefield encapsulation
cisco-h
Special mode for communicating with a Cisco in HDLC-mode with Cisco-
keepalive switched off.
ethernet
ethernet over ISDN (MAC-header included)
syncppp
Synchronous PPP over ISDN
uihdlc
raw ip with additional ui-header
cisco-hk
Special mode for communicating with a Cisco in HDLC-mode with Cisco-
keepalive switched on.
x25iface
Provides an interface as required by the Linux X.25 PLP protocol implementa-
tion (requires Linux 2.1.x or newer).
If encapsulation is omitted, the current setting is printed.
l2_prot name [protocol]
Set the layer-2 protocol for interface name. Possible values for protocol
are:
x75i, x75ui, x75bui and hdlc. If protocol is omitted the current setting is
printed.
l3_prot name [ protocol ]
Set the layer-3 protocol for interface name. At the moment only trans is
supported here. If protocol is omitted the current setting is printed.
list name
List all parameters and the charge info for interface name. If name is all,
then all interfaces are listed.
status name
Show the connection status for interface name. The output can be one of the
following types:
ippp0 not connected
There is no connection
ippp0 connected to 0123456789
There is an outgoing connection to phone number 0123456789
ippp0 connected from 0123456789
There is an incoming connection from phone number 0123456789
If the interface is connected, the exit status of the command is true, else it is
false.
If name is all, then the connection status for all interfaces is shown. The exit
status is always true in this case.
If name is active, then only those interfaces that are currently connected are
shown. The exit status is always true in this case.
verbose num
Set verbosity level to num.
hangup name
The connection of interface name is closed immediately.
bind name driverId,channel [exclusive]
Binds an interface name to a physical channel. The driverId identifies a
specific S0-Port. The channels of a port start counting with zero. If exclu-
sive is given, other interfaces cannot use that channel anymore. Otherwise,
the channel may be used by other interfaces.
unbind name
Unbinds a the previously bound interface name.
pppbind name [num]
Binds the interface name to an ippp device /dev/ipppnum. This works only
for synchronous ppp. The value must be a number. If num is omitted and name
is called ipppX , then the interface is bound to /dev/ipppX.
pppunbind name
Unbinds the previously bound interface name.
busreject driverId [on|off]
If switched on, instead of ignoring incoming calls not matching any inter-
face, isdn4linux responds with a REJECT to those calls. If switched off,
isdn4linux is passive, allowing other devices connected to the same S0-bus
to answer the call. You normally should not enable this feature, if the
ISDN adaptor is not the only device connected to the S0-bus. Otherwise it
could happen, that isdn4linux rejects an incoming call which belongs to
another device on the bus.
addslave name slave
Adds a slave interface named slave to interface name for raw channel-
bundling. For bundling of more than two channels, any number of slaves can
be added to an interface by using this command repeatedly. name must refer
to an existing "master" interface (not a slave). Slave interfaces are not
visible to the kernel, however all usual ISDN settings can be configured.
Because slave interfaces are not visible to the kernel, they are configured
"through" their "master", so it is important that slave interfaces are added
before the corresponding "master" is started by ifconfig. If the "master"
is already up, it has to be shutdown with ifconfig down ... otherwise the
addslave command will be rejected.
sdelay name num
Set delay for slave-dialing. The master interface name has to have a load
of more than trigger cps for at least num seconds, before its slave starts
dialing.
Note that this only works for rawIP, not MPPP!
trigger name num
Set trigger level for slave-dialing. The master interface name has to have
a load of more than num cps for at least sdelay seconds, before its slave
starts dialing.
Note that this only works for rawIP, not MPPP!
addlink name
For MPPP, this adds a slave interface to the existing connection, i.e. con-
nect the extra channel now. It is like a dial command for the extra channel.
This also means that addlink will only work if the master interface name
must already be connected! Also, the dialmode for the slave interface must
be auto.
removelink name
For MPPP, this removes a slave interface from the existing connection, i.e.
hangup the extra channel now.
dial name
Force dialing of interface name.
mapping driverId MSN0[,MSN1[,MSN2]] ... [,MSN9]
Installs a mapping-table for MSN<->EAZ-mapping. See README for details.
WILDCARDS
When using isdnctrl addphone name in num to add phone numbers to the incoming-call
accept-list of an interface, wildcards similar to shell wildcards can be used. The
following wildcards are supported:
? one arbitrary digit
* zero or arbitrary number of digits
[list] one of the digits in list
[1-5] one digit in the range of (including) 1 and 5.
^ if this appears as the first character in a list, inverts the list.
