9 isdnctrl action device ...
10
12 isdnctrl is used to create and delete network interfaces for ISDN, set
13 up the various parameters and phone numbers for dial in and dial out.
14 It is also used to list the current parameters of an already configured
15 network interface. isdnctrl is not needed for configuration of ISDN
16 ttys!
17 The use of isdnctrl is independent of the hardware driver.
19
21 The following actions may be given to isdnctrl.
22 addif name
24 Adds a new ISDN interface name to the kernel. If name is omit‐
25 ted, the kernel will use ethX, where X is an increasing number
26 starting from 0. This is probably not useful with ISDN so using
27 a name like isdn0 (for raw ip interfaces) or ippp0 (for synchro‐
28 nous PPP interfaces) is always recommended.
29 delif name [force]
31 Removes the ISDN interface name from the kernel. If the optional
32 keyword force is appended, isdnctrl executes ifconfig name down
33 before removing it.
34 reset [force]
36 Removes all ISDN interfaces from the kernel if it is possible.
37 If the optional keyword force is appended, isdnctrl executes
38 ifconfig name down before removing an interface.
39 ifdefaults name
41 resets the interface name to some reasonable defaults.
42 dialmode name [off|manual|auto]
44 Sets the dial mode of the interface to one of:
45 off
47 no connection can be made; an existing connection is terminated
48 immediately. Incoming connections are also not possible.
49 manual
51 manual dialing / hangup; a connection will only be made after
52 isdnctrl dial name but the line will be disconnected after the
53 huptimeout value set if using kernel drivers updated since 1 Nov
54 1998; otherwise an explicit isdnctrl hangup name will be needed
55 to cause the connection to be dropped.
56 Incoming connections are possible; however, if this interface is
57 configured in callback in mode, the callback dial will not hap‐
58 pen (as this is actually an outgoing connection, not an incoming
59 one).
60 auto
62 autodial mode; an outgoing packet will trigger a dialout, and a
63 hangup will occur after the huptimeout value specified (see
64 below).
65 An interface in auto dial mode will call another system back (if
66 configured in callback in mode).
67 auto was the "old" behaviour (as it was before dialmode was
69 implemented).
70 If no argument is given, the current dialmode value is dis‐
72 played.
73 You can give all as the interface name; the command will then be
75 executed for all interfaces.
76 addphone name out num
78 Adds the phone number num to the list of outgoing numbers of the
79 ISDN interface name. Numbers in this list are used to dial the
80 remote station if the connection is down and packets are to be
81 sent via the interface (Dial on demand). More than one number
82 can be set by calling isdnctrl addphone repeatedly. If more than
83 one number is set, these will be tried one after another (the
84 last added number is tried first, etc.). When using a german
85 SPV-type connection, the number has to be prefixed by a capital
86 S.
87 addphone name in num
89 Adds the phone number num to the list of incoming numbers of the
90 ISDN interface name. Numbers in this list are used to verify
91 access permission of the remote station if an incoming call is
92 received. The verification can be disabled by setting the inter‐
93 face into insecure mode using isdnctrl name secure off. If the
94 list is empty, incoming calls are disabled. More than one num‐
95 ber can be added by calling isdnctrl addphone repeatedly. Also
96 wildcards can be used (see below).
97 delphone name in|out num
99 Removes phone number num from the incoming or outgoing phone
100 list.
101 eaz name [num]
103 Set the EAZ (German 1TR6 protocol) or MSN (Euro-ISDN E-DSS1) for
104 ISDN interface name to num. For an EAZ this is only one digit,
105 while for an MSN num is the whole MSN (usually the local phone
106 number). If num is omitted, isdnctrl prints the current setting
107 for ISDN interface name.
108 huptimeout name [seconds]
110 Set the hangup timeout for ISDN interface name to seconds. If
111 there is inactivity (i.e. no traffic on the interface) for the
112 given time the driver automatically shuts down the connection.
113 If seconds is omitted isdnctrl prints the current setting for
114 interface name.
115 cbdelay name [seconds]
117 Set the callback delay for ISDN interface name to seconds. If
118 callback mode for this interface is in, dialing is delayed the
119 given time. If the callback mode is out, after dialing out and
120 waiting the given time, a hangup is issued to free the line for
121 the incoming callback from the remote machine. This hangup-
122 after-dial is disabled by setting cbdelay to 0. If seconds is
123 omitted isdnctrl prints the current setting for interface name.
124 dialmax name [num]
126 Set the number of dial attempts for ISDN interface name to num.
127 If dialing, each phone number is tried this many times before
128 giving up. If num is omitted isdnctrl prints the current set‐
129 ting for interface name.
130 ihup name [on|off]
132 Turn on or off the hangup timeout for incoming calls on inter‐
133 face name. If on or off is omitted the current setting is
134 printed.
135 chargehup name [on|off]
137 Turn on or off hangup before next charge info for interface
138 name. This can only be used if the ISDN provider transmits
139 charge info during and after the connection. If set to on, the
140 driver will close the connection just before the next charge
141 info will be received if the interface is inactive. If on or off
142 is omitted the current setting is printed.
143 chargeint name [seconds]
145 If seconds are given, the charge interval for the given inter‐
146 face is set. This may be useful on ISDN lines with no chargeinfo
147 or no online chargeinfo. The connection will be closed 2 seconds
148 before the end of the next estimated charge interval if huptime‐
149 out seconds of inactivity have been reached. If ihup is on,
150 incoming connections are closed by this mechanism also. On
151 lines with online charge info you also might ask by chargeint
152 name for the current charge interval as delivered from the tele‐
153 com on a given interface.
154 secure name [on|off]
156 Turns on or off the security feature for interface name. If set
157 to on, incoming calls will only be accepted if the calling num‐
158 ber can be found in the incoming access list. See description of
159 action addphone for information about how to add numbers to this
160 list. If on or off is omitted, the current setting is printed.
161 callback name [mode]
163 Set callback mode for interface name to mode mode. If callback
164 mode is in, then after getting an incoming call, a callback is
165 triggered. If callback mode is out, then the local system does
166 the initial call and then waits for callback of the remote
167 machine. The option on is available only for compatibility with
168 older versions. Its meaning is the same like in. If callback
169 mode is off, calls are handled normally without special process‐
170 ing.
171 cbhup name [on|off]
173 Turns on or off Hangup (Reject) for interface name before start‐
174 ing callback. If cbhup is on, when receiving an incoming call,
175 the interface first rejects that call before the callback
176 sequence is started. If on or off is omitted, the current set‐
177 ting is printed.
178 encap name [encapsulation]
180 Set the encapsulation mode for interface name. Possible encap‐
181 sulations are:
182 rawip
184 raw ip encapsulation (default)
185 ip
187 IP + typefield encapsulation
188 cisco-h
190 Special mode for communicating with a Cisco in HDLC-mode with
191 Cisco-keepalive switched off.
192 ethernet
194 ethernet over ISDN (MAC-header included)
195 syncppp
197 Synchronous PPP over ISDN
198 uihdlc
200 raw ip with additional ui-header
201 cisco-hk
203 Special mode for communicating with a Cisco in HDLC-mode with
204 Cisco-keepalive switched on.
205 x25iface
207 Provides an interface as required by the Linux X.25 PLP protocol
208 implementation (requires Linux 2.1.x or newer).
209 If encapsulation is omitted, the current setting is printed.
211 l2_prot name [protocol]
213 Set the layer-2 protocol for interface name. Possible values
214 for protocol are:
215 x75i, x75ui, x75bui and hdlc. If protocol is omitted the cur‐
216 rent setting is printed.
217 l3_prot name [ protocol ]
219 Set the layer-3 protocol for interface name. At the moment only
220 trans is supported here. If protocol is omitted the current
221 setting is printed.
222 list name
224 List all parameters and the charge info for interface name. If
225 name is all, then all interfaces are listed.
226 status name
228 Show the connection status for interface name. The output can
229 be one of the following types:
230 ippp0 not connected
232 There is no connection
233 ippp0 connected to 0123456789
235 There is an outgoing connection to phone number 0123456789
236 ippp0 connected from 0123456789
238 There is an incoming connection from phone number 0123456789
239 If the interface is connected, the exit status of the command is true,
241 else it is false.
242 If name is all, then the connection status for all interfaces is shown.
243 The exit status is always true in this case.
244 If name is active, then only those interfaces that are currently con‐
245 nected are shown. The exit status is always true in this case.
246 verbose num
248 Set verbosity level to num.
249 hangup name
251 The connection of interface name is closed immediately.
252 bind name driverId,channel [exclusive]
254 Binds an interface name to a physical channel. The driverId
255 identifies a specific S0-Port. The channels of a port start
256 counting with zero. If exclusive is given, other interfaces can‐
257 not use that channel anymore. Otherwise, the channel may be
258 used by other interfaces.
259 unbind name
261 Unbinds a the previously bound interface name.
262 pppbind name [num]
264 Binds the interface name to an ippp device /dev/ipppnum. This
265 works only for synchronous ppp. The value must be a number. If
266 num is omitted and name is called ipppX , then the interface is
267 bound to /dev/ipppX.
268 pppunbind name
270 Unbinds the previously bound interface name.
271 busreject driverId [on|off]
274 If switched on, instead of ignoring incoming calls not matching
275 any interface, isdn4linux responds with a REJECT to those calls.
276 If switched off, isdn4linux is passive, allowing other devices
277 connected to the same S0-bus to answer the call. You normally
278 should not enable this feature, if the ISDN adaptor is not the
279 only device connected to the S0-bus. Otherwise it could happen,
280 that isdn4linux rejects an incoming call which belongs to
281 another device on the bus.
282 addslave name slave
285 Adds a slave interface named slave to interface name for raw
286 channel-bundling. For bundling of more than two channels, any
287 number of slaves can be added to an interface by using this com‐
288 mand repeatedly. name must refer to an existing "master" inter‐
289 face (not a slave). Slave interfaces are not visible to the ker‐
290 nel, however all usual ISDN settings can be configured. Because
291 slave interfaces are not visible to the kernel, they are config‐
292 ured "through" their "master", so it is important that slave
293 interfaces are added before the corresponding "master" is
294 started by ifconfig. If the "master" is already up, it has to
295 be shutdown with ifconfig down ... otherwise the addslave com‐
296 mand will be rejected.
297 sdelay name num
300 Set delay for slave-dialing. The master interface name has to
301 have a load of more than trigger cps for at least num seconds,
302 before its slave starts dialing.
303 Note that this only works for rawIP, not MPPP!
304 trigger name num
307 Set trigger level for slave-dialing. The master interface name
308 has to have a load of more than num cps for at least sdelay sec‐
309 onds, before its slave starts dialing.
310 Note that this only works for rawIP, not MPPP!
311 addlink name
314 For MPPP, this adds a slave interface to the existing connec‐
315 tion, i.e. connect the extra channel now. It is like a dial com‐
316 mand for the extra channel.
317 This also means that addlink will only work if the master inter‐
318 face name must already be connected! Also, the dialmode for the
319 slave interface must be auto.
320 removelink name
323 For MPPP, this removes a slave interface from the existing con‐
324 nection, i.e. hangup the extra channel now.
325 dial name
328 Force dialing of interface name.
329 mapping driverId MSN0[,MSN1[,MSN2]] ... [,MSN9]
331 Installs a mapping-table for MSN<->EAZ-mapping. See README for
332 details.
333
335 When using isdnctrl addphone name in num to add phone numbers to the
336 incoming-call accept-list of an interface, wildcards similar to shell
337 wildcards can be used. The following wildcards are supported:
338 ? one arbitrary digit
341 * zero or arbitrary number of digits
343 [list] one of the digits in list
345 [1-5] one digit in the range of (including) 1 and 5.
347 ^ if this appears as the first character in a list, inverts the
349 list.
