10 | INTRODUCTION | |
11 | ||
12 | Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs) | |
13 | and/or stand-alone hosts over vast distances with data transfer rates | |
14 | significantly higher than those achievable with commonly used dial-up | |
15 | connections. | |
16 | ||
17 | Usually an external device called `WAN router' sitting on your local network | |
18 | or connected to your machine's serial port provides physical connection to | |
19 | WAN. Although router's job may be as simple as taking your local network | |
20 | traffic, converting it to WAN format and piping it through the WAN link, these | |
21 | devices are notoriously expensive, with prices as much as 2 - 5 times higher | |
22 | then the price of a typical PC box. | |
23 | ||
24 | Alternatively, considering robustness and multitasking capabilities of Linux, | |
25 | an internal router can be built (most routers use some sort of stripped down | |
26 | Unix-like operating system anyway). With a number of relatively inexpensive WAN | |
27 | interface cards available on the market, a perfectly usable router can be | |
28 | built for less than half a price of an external router. Yet a Linux box | |
29 | acting as a router can still be used for other purposes, such as fire-walling, | |
30 | running FTP, WWW or DNS server, etc. | |
31 | ||
32 | This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux | |
33 | operating system and provides generic hardware-independent services for such | |
34 | drivers. Why can existing Linux network device interface not be used for | |
35 | this purpose? Well, it can. However, there are a few key differences between | |
36 | a typical network interface (e.g. Ethernet) and a WAN link. | |
37 | ||
38 | Many WAN protocols, such as X.25 and frame relay, allow for multiple logical | |
39 | connections (known as `virtual circuits' in X.25 terminology) over a single | |
40 | physical link. Each such virtual circuit may (and almost always does) lead | |
41 | to a different geographical location and, therefore, different network. As a | |
42 | result, it is the virtual circuit, not the physical link, that represents a | |
43 | route and, therefore, a network interface in Linux terms. | |
44 | ||
45 | To further complicate things, virtual circuits are usually volatile in nature | |
46 | (excluding so called `permanent' virtual circuits or PVCs). With almost no | |
47 | time required to set up and tear down a virtual circuit, it is highly desirable | |
48 | to implement on-demand connections in order to minimize network charges. So | |
49 | unlike a typical network driver, the WAN driver must be able to handle multiple | |
50 | network interfaces and cope as multiple virtual circuits come into existence | |
51 | and go away dynamically. | |
52 | ||
53 | Last, but not least, WAN configuration is much more complex than that of say | |
54 | Ethernet and may well amount to several dozens of parameters. Some of them | |
55 | are "link-wide" while others are virtual circuit-specific. The same holds | |
56 | true for WAN statistics which is by far more extensive and extremely useful | |
57 | when troubleshooting WAN connections. Extending the ifconfig utility to suit | |
58 | these needs may be possible, but does not seem quite reasonable. Therefore, a | |
59 | WAN configuration utility and corresponding application programmer's interface | |
60 | is needed for this purpose. | |
61 | ||
62 | Most of these problems are taken care of by this module. Its goal is to | |
63 | provide a user with more-or-less standard look and feel for all WAN devices and | |
64 | assist a WAN device driver writer by providing common services, such as: | |
65 | ||
66 | o User-level interface via /proc file system | |
67 | o Centralized configuration | |
68 | o Device management (setup, shutdown, etc.) | |
69 | o Network interface management (dynamic creation/destruction) | |
70 | o Protocol encapsulation/decapsulation | |
71 | ||
72 | To ba able to use the Linux WAN Router you will also need a WAN Tools package | |
73 | available from | |
74 | ||
75 | ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz | |
76 | ||
77 | where vX.Y.Z represent the wanpipe version number. | |

115 | ACKNOWLEDGEMENTS | |
116 | ||
117 | This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed | |
118 | by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x. Success of the WANPIPE | |
119 | together with the next major release of Linux kernel in summer 1996 commanded | |
120 | adequate changes to the WANPIPE code to take full advantage of new Linux | |
121 | features. | |
122 | ||
123 | Instead of continuing developing proprietary interface tied to Sangoma WAN | |
124 | cards, we decided to separate all hardware-independent code into a separate | |
125 | module and defined two levels of interfaces - one for user-level applications | |
126 | and another for kernel-level WAN drivers. WANPIPE is now implemented as a | |
127 | WAN driver compliant with the WAN Link Driver interface. Also a general | |
128 | purpose WAN configuration utility and a set of shell scripts was developed to | |
129 | support WAN router at the user level. | |
130 | ||
131 | Many useful ideas concerning hardware-independent interface implementation | |
132 | were given by Mike McLagan <mike.mclagan@linux.org> and his implementation | |
133 | of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). | |
134 | ||
135 | With the new implementation of the APIs being incorporated into the WANPIPE, | |
136 | a special thank goes to Alan Cox in providing insight into BSD sockets. | |
137 | ||
138 | Special thanks to all the WANPIPE users who performed field-testing, reported | |
139 | bugs and made valuable comments and suggestions that help us to improve this | |
140 | product. | |
141 | ||
142 | ||
143 | ||
144 | NEW IN THIS RELEASE | |
145 | ||
146 | o Updated the WANCFG utility | |
147 | Calls the pppconfig to configure the PPPD | |
148 | for async connections. | |
149 | ||
150 | o Added the PPPCONFIG utility | |
2fe0ae78 | 151 | Used to configure the PPPD daemon for the |
1da177e4 LT |
152 | WANPIPE Async PPP and standard serial port. |
153 | The wancfg calls the pppconfig to configure | |
154 | the pppd. | |
155 | ||
156 | o Fixed the PCI autodetect feature. | |
157 | The SLOT 0 was used as an autodetect option | |
158 | however, some high end PC's slot numbers start | |
159 | from 0. | |
160 | ||
161 | o This release has been tested with the new backupd | |
162 | daemon release. | |

377 | ||
378 | beta-2.1.4 Jul 2000 o Dynamic interface configuration: | |
379 | Network interfaces reflect the state | |
380 | of protocol layer. If the protocol becomes | |
381 | disconnected, driver will bring down | |
382 | the interface. Once the protocol reconnects | |
383 | the interface will be brought up. | |
384 | ||
385 | Note: This option is turned off by default. | |
386 | ||
387 | o Dynamic wanrouter setup using 'wanconfig': | |
388 | wanconfig utility can be used to | |
389 | shutdown,restart,start or reconfigure | |
390 | a virtual circuit dynamically. | |
391 | ||
392 | Frame Relay: Each DLCI can be: | |
393 | created,stopped,restarted and reconfigured | |
394 | dynamically using wanconfig. | |
395 | ||
396 | ex: wanconfig card wanpipe1 dev wp1_fr16 up | |
397 | ||
398 | o Wanrouter startup via command line arguments: | |
399 | wanconfig also supports wanrouter startup via command line | |
400 | arguments. Thus, there is no need to create a wanpipe#.conf | |
401 | configuration file. | |
402 | ||
403 | o Socket based x25api update/bug fixes. | |
404 | Added support for LCN numbers greater than 255. | |
405 | Option to pass up modem messages. | |
406 | Provided a PCI IRQ check, so a single S514 | |
407 | card is guaranteed to have a non-sharing interrupt. | |
408 | ||
409 | o Fixes to the wancfg utility. | |
410 | o New FT1 debugging support via *pipemon utilities. | |
411 | o Frame Relay ARP support Enabled. | |
412 | ||
413 | beta3-2.1.4 Jul 2000 o X25 M_BIT Problem fix. | |
414 | o Added the Multi-Port PPP | |
4ae0edc2 | 415 | Updated utilities for the Multi-Port PPP. |
1da177e4 LT |
416 | |
417 | 2.1.4 Aut 2000 | |
418 | o In X25API: | |
419 | Maximum packet an application can send | |
420 | to the driver has been extended to 4096 bytes. | |
421 | ||
422 | Fixed the x25 startup bug. Enable | |
423 | communications only after all interfaces | |
424 | come up. HIGH SVC/PVC is used to calculate | |
425 | the number of channels. | |
426 | Enable protocol only after all interfaces | |
427 | are enabled. | |
428 | ||
429 | o Added an extra state to the FT1 config, kernel module. | |
430 | o Updated the pipemon debuggers. | |
431 | ||
432 | o Blocked the Multi-Port PPP from running on kernels | |
433 | 2.2.16 or greater, due to syncppp kernel module | |
434 | change. | |
435 | ||
436 | beta1-2.1.5 Nov 15 2000 | |
2fe0ae78 | 437 | o Fixed the MultiPort PPP Support for kernels 2.2.16 and above. |
1da177e4 LT |
438 | 2.2.X kernels only |
439 | ||
440 | o Secured the driver UDP debugging calls | |
992caacf | 441 | - All illegal network debugging calls are reported to |
1da177e4 LT |
442 | the log. |
443 | - Defined a set of allowed commands, all other denied. | |
444 | ||
445 | o Cpipemon | |
446 | - Added set FT1 commands to the cpipemon. Thus CSU/DSU | |
5d3f083d | 447 | configuration can be performed using cpipemon. |
1da177e4 LT |
448 | All systems that cannot run cfgft1 GUI utility should |
449 | use cpipemon to configure the on board CSU/DSU. | |
450 | ||
451 | ||
452 | o Keyboard Led Monitor/Debugger | |
4ae0edc2 | 453 | - A new utility /usr/sbin/wpkbdmon uses keyboard leds |
992caacf | 454 | to convey operational statistic information of the |
1da177e4 LT |
455 | Sangoma WANPIPE cards. |
456 | NUM_LOCK = Line State (On=connected, Off=disconnected) | |
457 | CAPS_LOCK = Tx data (On=transmitting, Off=no tx data) | |
458 | SCROLL_LOCK = Rx data (On=receiving, Off=no rx data | |
459 | ||
460 | o Hardware probe on module load and dynamic device allocation | |
461 | - During WANPIPE module load, all Sangoma cards are probed | |
462 | and found information is printed in the /var/log/messages. | |
463 | - If no cards are found, the module load fails. | |
464 | - Appropriate number of devices are dynamically loaded | |
465 | based on the number of Sangoma cards found. | |
466 | ||
5d3f083d | 467 | Note: The kernel configuration option |
1da177e4 LT |
468 | CONFIG_WANPIPE_CARDS has been taken out. |
469 | ||
470 | o Fixed the Frame Relay and Chdlc network interfaces so they are | |
471 | compatible with libpcap libraries. Meaning, tcpdump, snort, | |
472 | ethereal, and all other packet sniffers and debuggers work on | |
992caacf | 473 | all WANPIPE network interfaces. |
1da177e4 LT |
474 | - Set the network interface encoding type to ARPHRD_PPP. |
475 | This tell the sniffers that data obtained from the | |
476 | network interface is in pure IP format. | |
477 | Fix for 2.2.X kernels only. | |
478 | ||
479 | o True interface encoding option for Frame Relay and CHDLC | |
480 | - The above fix sets the network interface encoding | |
481 | type to ARPHRD_PPP, however some customers use | |
482 | the encoding interface type to determine the | |
483 | protocol running. Therefore, the TURE ENCODING | |
484 | option will set the interface type back to the | |
485 | original value. | |
486 | ||
487 | NOTE: If this option is used with Frame Relay and CHDLC | |
488 | libpcap library support will be broken. | |
489 | i.e. tcpdump will not work. | |
490 | Fix for 2.2.x Kernels only. | |
491 | ||
492 | o Ethernet Bridgind over Frame Relay | |
493 | - The Frame Relay bridging has been developed by | |
494 | Kristian Hoffmann and Mark Wells. | |
495 | - The Linux kernel bridge is used to send ethernet | |
496 | data over the frame relay links. | |
497 | For 2.2.X Kernels only. | |
498 | ||
499 | o Added extensive 2.0.X support. Most new features of | |
500 | 2.1.5 for protocols Frame Relay, PPP and CHDLC are | |
501 | supported under 2.0.X kernels. | |
502 | ||
503 | beta1-2.2.0 Dec 30 2000 | |
504 | o Updated drivers for 2.4.X kernels. | |
505 | o Updated drivers for SMP support. | |
506 | o X25API is now able to share PCI interrupts. | |
507 | o Took out a general polling routine that was used | |
508 | only by X25API. | |
509 | o Added appropriate locks to the dynamic reconfiguration | |
510 | code. | |
511 | o Fixed a bug in the keyboard debug monitor. | |
512 | ||
513 | beta2-2.2.0 Jan 8 2001 | |
514 | o Patches for 2.4.0 kernel | |
515 | o Patches for 2.2.18 kernel | |
516 | o Minor updates to PPP and CHLDC drivers. | |
d533f671 | 517 | Note: No functional difference. |
1da177e4 LT |
518 | |
519 | beta3-2.2.9 Jan 10 2001 | |
520 | o I missed the 2.2.18 kernel patches in beta2-2.2.0 | |
521 | release. They are included in this release. | |
522 | ||
523 | Stable Release | |
524 | 2.2.0 Feb 01 2001 | |
525 | o Bug fix in wancfg GUI configurator. | |
526 | The edit function didn't work properly. | |
527 | ||
528 | ||
529 | bata1-2.2.1 Feb 09 2001 | |
530 | o WANPIPE TTY Driver emulation. | |
531 | Two modes of operation Sync and Async. | |
532 | Sync: Using the PPPD daemon, kernel SyncPPP layer | |
533 | and the Wanpipe sync TTY driver: a PPP protocol | |
534 | connection can be established via Sangoma adapter, over | |
535 | a T1 leased line. | |
536 | ||
537 | The 2.4.0 kernel PPP layer supports MULTILINK | |
538 | protocol, that can be used to bundle any number of Sangoma | |
539 | adapters (T1 lines) into one, under a single IP address. | |
540 | Thus, efficiently obtaining multiple T1 throughput. | |
541 | ||
542 | NOTE: The remote side must also implement MULTILINK PPP | |
543 | protocol. | |
544 | ||
545 | Async:Using the PPPD daemon, kernel AsyncPPP layer | |
546 | and the WANPIPE async TTY driver: a PPP protocol | |
547 | connection can be established via Sangoma adapter and | |
548 | a modem, over a telephone line. | |
549 | ||
550 | Thus, the WANPIPE async TTY driver simulates a serial | |
551 | TTY driver that would normally be used to interface the | |
552 | MODEM to the linux kernel. | |
553 | ||
554 | o WANPIPE PPP Backup Utility | |
555 | This utility will monitor the state of the PPP T1 line. | |
556 | In case of failure, a dial up connection will be established | |
557 | via pppd daemon, ether via a serial tty driver (serial port), | |
558 | or a WANPIPE async TTY driver (in case serial port is unavailable). | |
559 | ||
560 | Furthermore, while in dial up mode, the primary PPP T1 link | |
561 | will be monitored for signs of life. | |
562 | ||
563 | If the PPP T1 link comes back to life, the dial up connection | |
564 | will be shutdown and T1 line re-established. | |
565 | ||
566 | ||
567 | o New Setup installation script. | |
568 | Option to UPGRADE device drivers if the kernel source has | |
569 | already been patched with WANPIPE. | |
570 | ||
571 | Option to COMPILE WANPIPE modules against the currently | |
572 | running kernel, thus no need for manual kernel and module | |
fff9289b | 573 | re-compilation. |
1da177e4 LT |
574 | |
575 | o Updates and Bug Fixes to wancfg utility. | |
576 | ||
577 | bata2-2.2.1 Feb 20 2001 | |
578 | ||
579 | o Bug fixes to the CHDLC device drivers. | |
580 | The driver had compilation problems under kernels | |
581 | 2.2.14 or lower. | |
582 | ||
583 | o Bug fixes to the Setup installation script. | |
584 | The device drivers compilation options didn't work | |
585 | properly. | |
586 | ||
587 | o Update to the wpbackupd daemon. | |
588 | Optimized the cross-over times, between the primary | |
589 | link and the backup dialup. | |
590 | ||
591 | beta3-2.2.1 Mar 02 2001 | |
592 | o Patches for 2.4.2 kernel. | |
593 | ||
594 | o Bug fixes to util/ make files. | |
595 | o Bug fixes to the Setup installation script. | |
596 | ||
597 | o Took out the backupd support and made it into | |
598 | as separate package. | |
599 | ||
600 | beta4-2.2.1 Mar 12 2001 | |
601 | ||
602 | o Fix to the Frame Relay Device driver. | |
603 | IPSAC sends a packet of zero length | |
604 | header to the frame relay driver. The | |
605 | driver tries to push its own 2 byte header | |
606 | into the packet, which causes the driver to | |
607 | crash. | |
608 | ||
609 | o Fix the WANPIPE re-configuration code. | |
610 | Bug was found by trying to run the cfgft1 while the | |
611 | interface was already running. | |
612 | ||
613 | o Updates to cfgft1. | |
614 | Writes a wanpipe#.cfgft1 configuration file | |
615 | once the CSU/DSU is configured. This file can | |
616 | holds the current CSU/DSU configuration. | |
