How do I get started with synchronous PPP (sPPP) ? -================================================================================ - - Of course you first have to have sPPP interfaces in your kernel. If - you installed everything using FreeBSD/install.sh then the correct - entries should have been automatically made in /sys/conf/files for you. - For NetBSD it isn't quite as simple since NetBSD/install-netbsd.sh does - not do it for you. - - Then all you need to do is put an entry like this: - - device "i4bisppp" 4 - - into your kernel configuration file (if it's not already there) and - generate and boot the new kernel. The above line will give you 4 - sPPP interfaces - isp0 to isp3. - - Then just modify /etc/isdn/isdnd.rc (see the example in etc-isdn/isdnd.rc) - to suit your needs (telephone numbers, etc). - - The next step is to read the ispppcontrol man page and then to look at - etc/rc.isdn-PPP. ispppcontrol is a very important component in getting - sPPP working correctly and the ispppcontrol lines in your /etc/rc.isdn - must be correct. - - In my experience there are two things which can cause problems: - - 1) the authproto line has to agree with what your ISP desires. In - general I've found that it's best to have something like this - - - ispppcontrol <interface> myauthproto={pap,chap} myauthname=<AuthName> - myauthsecret=<AuthSecret> hisauthproto=none callin - - The "hisauthproto=none" is usually needed because the ISP does not want - to authorise himself to you; he expects you to authorize yourself to him ! - I once forgot to set hisauthproto and it took me quite a while to figure - out why I couldn't connect. - - 2) the IP address at your ISP's end must be correct. - - How can I find out (1) whether my ISP wants pap or chap and (2) what his - IP address is ? you might ask. Generally, your ISP should have provide - this information to you. But, if he didn't, or you've mislayed the - documentation (as I did), there's still hope. - - Fortunately, J"org Wunsch implemented the sPPP kernel code so that it - provides all the information required if the interface is configured - with the debug flag set (e.g. ``ifconfig isp0 debug''). It's just a - little cryptic. - - By the way, I suggest turning the debug flag on until you have things - working and then turning it off. The debug output is rather voluminous - and could fill up your /var partition, otherwise. - - The debug output will appear on the console and also be logged to - /var/log/messages (under FreeBSD) unless you changed /etc/syslog.conf. - - A. How to figure out the authproto - ---------------------------------- - - Here is an example where I configured isp0 with myauthproto=pap, my - ISP wanted chap, but was willing to accept pap: - - /kernel: isp0: lcp up(starting) - /kernel: isp0: lcp output <conf-req id=0x7 len=10 5-6-34-e4-30-5a> - /kernel: isp0: lcp input(req-sent): <conf-req id=0x1 len=30 0-4-0-0-1-4-5- - f4-3-5-c2-23-5-11-4-5-f4-13-9-3-0-c0-7b-6e-fe-b5> - ^^^^^ - |___ c223 is chap, it's what the ISP wants to use - - /kernel: isp0: lcp parse opts: 0x0 [rej] mru auth-proto 0x11 [rej] - x13 [rej] send conf-rej (I didn't agree) - /kernel: isp0: lcp output <conf-rej id=0x1 len=21 0-4-0-0-11-4-5-f4-13-9-3- - 0-c0-7b-6e-fe-b5> - /kernel: isp0: lcp input(req-sent): <conf-ack id=0x7 len=10 5-6-34-e4-30-5a> - /kernel: isp0: lcp input(ack-rcvd): <conf-req id=0x2 len=13 1-4-5-f4-3-5- - c2-23-5> - /kernel: isp0: lcp parse opts: mru auth-proto - /kernel: isp0: lcp parse opt values: mru 1524 auth-proto [mine 0x0 != - his chap] send conf-nak (we want to use pap, not chap) - /kernel: isp0: lcp output <conf-nak id=0x2 len=9 3-5-c0-23-5> - ^^^^^ - |___ c023 is pap - - /kernel: isp0: lcp input(ack-rcvd): <conf-req id=0x3 len=12 1-4-5-f4-3-4- - c0-23> (he agrees to use pap) - /kernel: isp0: lcp parse opts: mru auth-proto - /kernel: isp0: lcp parse opt values: mru 1524 auth-proto send conf-ack - /kernel: isp0: lcp output <conf-ack id=0x3 len=12 1-4-5-f4-3-4-c0-23> - he agrees to use pap ___|^^^^^ - - so, if you have problems in the lcp phase, check which authentication method - your ISP wants to use. Usually chap is prefered, but pap will be accepted. - - B. How to figure out the ISP's IP address - ----------------------------------------- - - ====================================================================== - - UPDATE NOTE (February 8, 1999): - - Jan Riedinger writes: - --------------------- - >I further think Gary should mention - >in the FAQ in the section "B. How to figure out the ISP's IP address - >that it isn't normaly necessary to do it because of the auto - >address negotiation. - - Gary answers: - ------------- - I think you're right. I wrote that stuff before the support for - negotiation of the IPS's address was added to if_spppsubr.c. - - ====================================================================== - - - I also intentionally configured the interface with the wrong address for - my ISP, like this: - - ifconfig isp0 0.0.0.0 10.0.0.1 debug link1 - - this means that I want the ISP to assign me an address (the 0.0.0.0) and - that I expect him to use 10.0.0.1 (which is wrong). Here's the result: - (note that these addresses have been changed by me) - - /kernel: isp0: phase network - /kernel: isp0: ipcp open(initial) - /kernel: isp0: ipcp up(starting) - /kernel: isp0: ipcp output <conf-req id=0x9 len=10 3-6-0-0-0-0> - /kernel: isp0: ipcp input(req-sent): <conf-req id=0x1 len=16 2-6-0-2d-f-1- - 3-6-c-22-38-4e> - /kernel: isp0: ipcp parse opts: compression [rej] address send conf-rej - /kernel: isp0: ipcp output <conf-rej id=0x1 len=10 2-6-0-2d-f-1> - /kernel: isp0: ipcp input(req-sent): <conf-nak id=0x9 len=10 3-6-c-22-38-4e> - /kernel: isp0: ipcp nak opts: address [wantaddr 12.34.56.78] [agree] - ^^^^^ - |___ he assigns me this - - /kernel: isp0: ipcp output <conf-req id=0xa len=10 3-6-c3-b4-eb-63> - /kernel: isp0: ipcp input(req-sent): <conf-req id=0x2 len=10 3-6-62-4c-36-20> - /kernel: isp0: ipcp parse opts: address - /kernel: isp0: ipcp parse opt values: address 98.76.54.32 [not agreed] - ^^^^^ - |_this is *his* address - send conf-nak - /kernel: isp0: ipcp output <conf-nak id=0x2 len=10 3-6-a-0-0-1> - I expect a different address and (incorrectly) reject what he wants. - I tell him that I expect 10.0.0.1. After this the connection fails. - - Anyway, I now know that his address is really 98.76.54.32 and can use - it to correctly configure the interface. - - With the correct IP address I shoulkd now be able to connect with no - problems. As stated above, the authorization protocol is normally not - so important since most ISPs are willing to use pap, although chap is - more secure. Generally, I'd try chap first and only switch to pap if - the ISP doesn't accept it. - - (by Gary Jennejohn, Home - garyj@muc.de, Work - garyj@fkr.dec.com) - - - -2. does anyone know a software that can receive/send fax over ISDN ? -================================================================================ - - > Hi, - > - > does anyone know a software that can receive/send fax over ISDN? I am - > using a Fritz!Card, which can handle group 3 (analogous) fax, but I - > can't find any hint in the i4b software that this is supported in any - > way. - -This is probably not implemented. - -Implementing G3 fax in ISDN would mean simulating an analog modem -on the digital link. This means having to generate the right waveforms -for the modulated data, and receive analog data from the other end -which you had to run FFT analysis on and then interpret. - -In addition you have to do this in realtime, to be able to deal with -the timing involved in the fax protocol, something neither -FreeBSD or Linux is good at in their native form.. - -A third point is that a software simulated faxmodem usually does not -work well. I tested Teles software faxmodem in Win-95 towards an Ericsson V34 -HE modem, and was able to send faxes from the ISDN card at 4800 baud -only, and receive faxes ad 9600 baud only(!) (And it is not the -Ericsson modems fault, it works flawlessly towards other fax machines.) - -My point is that the best thing to do is to use an ordinary faxmodem -to handle faxes with Hylafax of mgetty+sendfax or efax, or you may use -a combined ISDN card with an analog part. - -Of course, if you are crazy enough, you may try to implement a -software simulated modem in e.g. RT-linux, or a similar realtime -extension for FreeBSD. - -Best regards, -Nils Ulltveit-Moe (etonumo@eto.ericsson.se) - - - -3. does i4b callback only work with setups where the remote end returns a busy ? -================================================================================ - -> Is my assumption correct, does i4b callback only work with setups where -> the remote end returns a busy on the dialin? - -Yes - otherwise you'll pay for the connection, at least here in Germany. - -Most routers support two kind of callbacks - the one that i4b supports -means: the called system rejects (so no charge for this connection), waits -a configurable time and the calls back. Information on who has called and -who is to be called back relies on the ISDN calling party number information -and stuff statically configured in the routers (or isnd's) configuration. - -The other type of callback (not supported by i4b right now) means: the -called system accepts the connection and starts ppp negotiation. During this -the ppp's aggree to do a callback. Information on who called in and who is -going to be called back is subject to the authentication/negotiation already -done by the two ppp's. Then ppp closes down, the connection is disconnected -and the called system calls back. - -I've never seen someone actually use the second type due to its obvious -disadvantages. It may be usefull if you travel, call in from an unknown -number and want to be called back at that number. - -Martin Husemann <martin@rumolt.teuto.de> - - -4. trouble with kernel options IPFIREWALL and IPDIVERT and natd -================================================================================ - - NOTICE: section obsolete since IP address changes are handled properly now! - =========================================================================== - -This section -> Trying to build a router/gateway between my privat Ethernet and -> the Internet (via my ISP), I have problems with I4B or NAT (I think:). -> -> The 2.2.5-R kernel with options IPFIREWALL and IPDIVERT works fine -> with ISDN4BSD 0.50-alpha and firewall rule 'pass all from any to any'. -> However, when I add 'divert natd all from any to any via isp0' -> and start natd, name server lookups to the ISP's NS don't work. -> -> Also, ping and nslookup fails from any other internal host. - -I had exactly the same problems. natd doesn't seem to get a message if -the IP address of the interface changes (after successful dialout). -I have to manually send a HUP signal to natd. I do this via the following -(ugly?!) hack: - -I added the following two lines to the system section of isdnd.rc: -regexpr = "call active" # look for matches in log messages -regprog = hup_natd # execute program whan match is found - -The small script "hup_natd", located in /etc/isdn, looks like: -#!/bin/sh -pid=`cat /var/run/natd.pid` -kill -HUP $pid -sleep 3 -kill -HUP $pid -sleep 5 -kill -HUP $pid - -It looks ugly, but at least for me it works. The two sleeps are necessary -since I have to wait for ppp negotiation to complete (I don't get a message -from isdnd for that). If I'm lucky I have my connection after 3 seconds, -but 8 seconds should suffice for worst case (the first HUP without a sleep -sometimes even succeeded on a slow 486/33 with 8MB RAM, more HUPs don't hurt). - -I'm really interested in some more elegant method. - -Daniel (rock@cs.uni-sb.de) - - -Arve Ronning replied: -===================== - -> I had exactly the same problems. natd doesn't seem to get a message if -> the IP address of the interface changes (after successful dialout). - -Well, it (natd) _does_ pick up the dynamic address supplied for isp0. -Try 'natd -verbose ...' and you'll see it. Otherwise I agree, there is -certainly something missing in natd's functionality, or maybe sppp -does'nt -supply what it's supposed to ?? - -> I have to manually send a HUP signal to natd. I do this via the following -> (ugly?!) hack: - -YES...super; strange but correct. It works when I send natd a -HUP after -sppp is up. Thanx for the tip. However, natd must be -HUPed _every_ time -sppp has been down (idle timeout) and comes back up! - -> I'm really interested in some more elegant method. - -So am I, let's see what may come out of the discussion on the list. - - - -5. I want to use -r with isdnd but it does not work -================================================================================ - -> > Use isdnd in fullscreen mode. -> -> I tried that already, but got an error when I start isdnd that way: -> -> /usr/local/bin/isdnd -d 0xf9 -f -r /dev/ttyv1 -t cons25 -> -> root is logged in on device /dev/ttyv1, the message in /var/log/messages looks like: -> -> "May 22 11:52:28 asterix isdnd[4160]: ERR ERROR, cannot setup tty as controlling terminal: Operation not permitted" -> -> How can I give this device permission ? - - -In case you want to use switch "-r" noone else _must_ use the tty you redirect -to, you have to remove the getty from the virtual terminal in /etc/ttys and -restart the init process. - - -6. How do I configure and run the answering machine (under FreeBSD 2.2.x) ? -================================================================================ - -The answering machine will be activated, when isdnd executes the program -that has been named in "/etc/isdn/isdnd.rc" in the section "telephone -answering" at entry "answerprog = ". If the program is executed -without a pathname, the answer program is expected in "/etc/isdn". -Examples of such programs can be found in "/etc/isdn/samples". They -are named: - - "answer" answers only, no recording - "record" answers, and records messages - "tell" the number of the calling person is told, - no recording. - "tell-record" calling number as answer, message is recorded - "isdntel.sh" answers and records messages; by using the - program "isdntel", one has the control over - the recorded messages in the directory - "/var/isdn". Look at "man isdntel" and - "man isdntelctl". - -These programs have to be altered to suit your needs. Unfortunately there -is no program with which you can record your answer message. This is not -really bad, because you only have to alter the above mentioned program -"record" a bit (comment out the "if ... fi" statements for the beep -and msg messages). You have to create the directory "/var/isdn" first in -order to record messages. They will be stored in this location then. - -Stefan Herrmann <stefan@asterix.webaffairs.net> - - -7. Teles S0/16.3 ... unknown ? -================================================================================ -Hi, - -I have just purchased a Teles S0/16.3 card. -But it's not what i4b is looking for .... I mean, it's a different card. - -The docs (and sources)of i4b talks about a Telws S0/16.3 card with 3 -address: d80 etc. - -This one (is not PnP) has jumpers for 0x180 0x280 0x380. - -It has the SIemens Chips numbered PSB 21525 N (HSCX TE V2.1) and PSB -2186N V1.1 (ISAC-S TE). - -I undestand that the 16.3c is not supported, but over this board is -written "TELES.S0/16.3 Revision 1.3" - -Can anybody tell me what is this card ??? - -answer: -------- - -It's not a different card. The jumpers are documented to select -IO-address 0x180, 0x280 or 0x380 in some TELES manuals. -But in fact they select the addresses 0xd80, 0xe80 or 0xf80. - -Wolfgang - - -And an additional note from Poul-Henning Kamp: ----------------------------------------------- -There is an intricate story behind this, in short some ISA cards -only decode the first 10 address bits (0x3ff), which over the years -has resulted in a mutation the "de-facto-spec" such that addressbits -10-15 can be used by the card for selecting various stuff. This -is extensively used on obscure cards with massive IO needs, sound, -IEEE488 and ISDN cards often belong in this category. - - - -8. How do i integrate a new lowlevel driver into i4b ? -================================================================================ - -1) Request a flag value from me -2) add an entry for the card into FreeBSD/CONFIG -3) add driver filename to FreeBSD/files.i386.cat -4) add entry for the card to FreeBSD/options.i386.cat -5) add support to print type of card to diehl/diehlctl/main.c -6) add support to print type of card to isdnd/support.c, name_of_controller() -7) place your file as named in 3) into directory layer1 -8) add the flag value and function prototypes to layer1/i4b_l1.h -9) add support for NetBSD to layer1/isa_isic.c -10) add support for attach/probe to layer1/i4b_isic.c -11) add card type to i4b/i4b_ioctl.h and update CARD_TYPEP_MAX -12) add an entry to the man page man/isic.4 - -Produce diffs (please use context diffs, flag "-c" for diff) and send them in. - - -9. Why it always says "no Space in TX FIFO - State F4 awaiting" ? -================================================================================ - -as I wrote about two weeks ago I had massive problems concerning this -"no space in TX FIFO"-thing, - -/kernel: i4b-L1-ph_data_req: No Space in TX FIFO, state = F4 Awaiting Signal - -Even though I used a correctly recognized Teles S0/16.3 nonpnp isdncard, -nothing worked, errormsgs were flooding the console until I rebooted the box. - -I decided to play around in the BIOS-settings, I first just set them all -to default, which didn't work, and then changed lots of things - unfortunately -I can't remember them. After about hundreds of trial 'n errors I gave up. - -A few days ago I just made another attempt, booted the box and to my surprise -it all worked without the smallest problem, great data rates :) - -I tried hard to found what the something special was I changed in the BIOS -settings, but I just couldnt get isdnd back to its stupid behaviour it -showed all the time before, but I would recommend everybody who has this -kind of problem to look into his BIOS. - - (from Meike Aulbach, strange@stoned.rhein-main.de) - - -i4b now works for me, I had a USB-device interfering on IRQ 9, -which was supposed to be only for my Creatix Card. -(NetBSD 1.3, Creatix) - -Strange enough, my DOS s0-test worked, are they just polling the card? - -Even when the testsoftware under DOS is working, don't be shure, that -your hw-setup is correct for xxx(x)BSD. Triplecheck all your IRQ and -enable and disable PNP to triple-verify. Even unconfigured devices can -block your card. ..... - -And that took me more than 2 months to discover :-(((( - - (from Andreas Lohrum, andreas.lohrum@consol.de) - - -when i changed the mainboard of a box that ran i4b alright, i forgot to -set 'used by isa' in the pnp-bios-settings for the irq of my teles -isdn-card. because of that some pci-card got the interrupt that the -isdn-card should have gotten. -i then also got this error: 'No space in TX FIFO'. - -The reason occurred to my rather quick, but i would think, that this would -be a nice hint in a FAQ :) - - (from Heiko Schaefer, hschaefer@fto.de) - - -after my huge amount of problems, Meike's hint (changing the -ISA/PNP-settings in the BIOS) finally fixed things. -I have only tried out this stuff with my Creatix-card, I'll check -out the PNP-stuff with my Sedlbauer-card soon too though. - - (from Harold Gutch, logix@foobar.franken.de) - - -10. Incoming alert - what does it mean ? -================================================================================ - -In the log on vty6 (isdnd full screen log) I'm seeing - -16.07.98 11:42:35 CHD 00001 rwth rate 90 sec/unit (rate) -16.07.98 11:42:35 CHD 00001 rwth dialing from 4191236 to 441291234 -16.07.98 11:42:35 CHD 00001 rwth outgoing call proceeding (ctl 0, ch 0) -16.07.98 11:42:35 CHD 00001 rwth incoming alert <<<<<<<<<<<<<<< -16.07.98 11:42:35 CHD 00001 rwth outgoing call active (ctl 0, ch 0) - -What does this 'incoming alert' mean? - - -It means that it is "ringing" at the remote end. - - -11. How do i change irq's on my teles 16.3 card ? -================================================================================ - -Question: - -So how do you change irq's on your teles 16.3 card (under FBSD or DOS, -I don't have and don't want to have Windows running on that computer) ? - -Answer: - -The irq is configured into the card each time the driver under whatever -OS you currently boot initializes the card. Thus, change the irq for the -isic driver in your kernel config file to one of the supported (!) irqs -for this card (hint: read "man isic") which is currently unused in your -machine and generate a new kernel. - - -12. NL: i'm getting CAUSE 100 or CAUSE 101 when dialling out -================================================================================ - -This one seems to be specific for the Netherlands. (-hm) - -Question: - -I'm trying to get i4b running on my new FreeBSD 2.2.8 system. The kernel -compiles smootly and everything is looking fine until it's time to dial. -I get the following error: - -Feb 10 20:31:00 goofy isdnd[498]: CHD 00018 I4BPPP outgoing call disconnected (remote) -Feb 10 20:31:00 goofy isdnd[498]: CHD 00018 I4BPPP cause 101: Message not compatible with call state (Q.850) -Feb 10 20:31:00 goofy isdnd[498]: ERR set_channel_idle: controller [0], invalid channel [-1]! -Feb 10 20:31:00 goofy isdnd[498]: ERR msg_disconnect_ind: set_channel_idle failed! - -The remote site is a Cisco 4000 type router. I used debug to take a view at -the ISDN events on the router but according to that the call doesn't arrive -over there. - -Same hardware has worked fine with FreeBSD 2.2.6/i4b 0.63. - -Who knows what's wrong? - - -Answer: - -This sounds very much like your local phone number or remote phone number -is configured wrongly... in the Netherlands you need to specify the number -EXCLUDING the city code... so if you live in Utrecht and your number is -0301234567 you specify 1234567. - -I have seen this in several locations in the Netherlands for years, not -just with i4b, but also with differentt isdn equipment.. why? guess it -simply depends on which operator defines your line or what exchange it -is connected to... :P -What I found is that what solved this with other isdn hardware/software, -also solves it for i4b.. ie.. make sure the local phone number is -specified, and is specified without the city code. -The numbering plan should be 'unknown' - -Anyway, it would be nice if the Dutch ptt (they are called KPN btw) -would tell us why this happens... they havent been able to tell me in the -past so I guess I give up on that, but if everyone finds out whats exactly -happening here I'd be interested to know... :) - -List of number configurations that I have found to almost always work in -the Netherlands: - -1. Local phone number: - usually your prefered msn without city code works here. - (ie, 1234567 if you would like to use 0201234567 for outgoing calls) - on some locations leaving it blank or defining it with the city code, - but without the leading 0 works as well here. - -2. remote phone number: - When this is a 'local' call, don't specify city code. - For calling parties in other cities you of cource have to use the city - code... in general you can say that KPN only accepts the shortest - possible notation where it would still be clear who you want to call. - -3. numbers for incomming call recognition: - KPN always specifies incoming caller ids with city code, but without - leading 0. so 0201234567 will be displayed as 201234567 - - -Hope this helps. -Bart - - (from Bart van Leeuwen bart@ixori.demon.nl) - - -14. I'm using sPPP. I can connect to my ISP but no TCP/IP services work. HELP! -============================================================================== - -This is probably because you have the RFC1323 - TCP Extensions for High -Performance - support turned on and your ISP (or some router in the loop) -is discarding the extensions. - -This can easily be checked by doing ``sysctl net.inet.tcp.rfc1323''. If the -result is 1, then the RFC1323 support is turned on. - -Turn this off by doing ``sysctl net.inet.tcp.rfc1323=0'' (This is -called "net.inet.tcp.do_rfc1323" under BSD/OS). - -For FreeBSD make sure that tcp_extension="NO" is in your /etc/rc.conf -(/etc/defaults/rc.conf with more recent versions of FreeBSD) and -/etc/rc.conf.local (in -STABLE and upcoming 3.2) - -This may be different for NetBSD, OpenBSD and BSD/OS. - -Martin Husemann writes: ------------------------ -This does apply for NetBSD too (and probably OpenBSD, since it's been -in NetBSD for a long time).
