Although router's job may be as simple as taking your local network -traffic, converting it to WAN format and piping it through the WAN link, these -devices are notoriously expensive, with prices as much as 2 - 5 times higher -then the price of a typical PC box. - -Alternatively, considering robustness and multitasking capabilities of Linux, -an internal router can be built (most routers use some sort of stripped down -Unix-like operating system anyway). With a number of relatively inexpensive WAN -interface cards available on the market, a perfectly usable router can be -built for less than half a price of an external router. Yet a Linux box -acting as a router can still be used for other purposes, such as fire-walling, -running FTP, WWW or DNS server, etc. - -This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux -operating system and provides generic hardware-independent services for such -drivers. Why can existing Linux network device interface not be used for -this purpose? Well, it can. However, there are a few key differences between -a typical network interface (e.g. Ethernet) and a WAN link. - -Many WAN protocols, such as X.25 and frame relay, allow for multiple logical -connections (known as `virtual circuits' in X.25 terminology) over a single -physical link. Each such virtual circuit may (and almost always does) lead -to a different geographical location and, therefore, different network. As a -result, it is the virtual circuit, not the physical link, that represents a -route and, therefore, a network interface in Linux terms. - -To further complicate things, virtual circuits are usually volatile in nature -(excluding so called `permanent' virtual circuits or PVCs). With almost no -time required to set up and tear down a virtual circuit, it is highly desirable -to implement on-demand connections in order to minimize network charges. So -unlike a typical network driver, the WAN driver must be able to handle multiple -network interfaces and cope as multiple virtual circuits come into existence -and go away dynamically. - -Last, but not least, WAN configuration is much more complex than that of say -Ethernet and may well amount to several dozens of parameters. Some of them -are "link-wide" while others are virtual circuit-specific. The same holds -true for WAN statistics which is by far more extensive and extremely useful -when troubleshooting WAN connections. Extending the ifconfig utility to suit -these needs may be possible, but does not seem quite reasonable. Therefore, a -WAN configuration utility and corresponding application programmer's interface -is needed for this purpose. - -Most of these problems are taken care of by this module. Its goal is to -provide a user with more-or-less standard look and feel for all WAN devices and -assist a WAN device driver writer by providing common services, such as: - - o User-level interface via /proc file system - o Centralized configuration - o Device management (setup, shutdown, etc.) - o Network interface management (dynamic creation/destruction) - o Protocol encapsulation/decapsulation - -To ba able to use the Linux WAN Router you will also need a WAN Tools package -available from - - ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz - -where vX.Y.Z represent the wanpipe version number. - -For technical questions and/or comments please e-mail to ncorbic@sangoma.com. -For general inquiries please contact Sangoma Technologies Inc. by - - Hotline: 1-800-388-2475 (USA and Canada, toll free) - Phone: (905) 474-1990 ext: 106 - Fax: (905) 474-9223 - E-mail: dm@sangoma.com (David Mandelstam) - WWW: http://www.sangoma.com - - -INSTALLATION - -Please read the WanpipeForLinux.pdf manual on how to -install the WANPIPE tools and drivers properly. - - -After installing wanpipe package: /usr/local/wanrouter/doc. -On the ftp.sangoma.com : /linux/current_wanpipe/doc - - -COPYRIGHT AND LICENSING INFORMATION - -This program is free software; you can redistribute it and/or modify it under -the terms of the GNU General Public License as published by the Free Software -Foundation; either version 2, or (at your option) any later version. - -This program is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS -FOR A PARTICULAR PURPOSE.

Success of the WANPIPE -together with the next major release of Linux kernel in summer 1996 commanded -adequate changes to the WANPIPE code to take full advantage of new Linux -features. - -Instead of continuing developing proprietary interface tied to Sangoma WAN -cards, we decided to separate all hardware-independent code into a separate -module and defined two levels of interfaces - one for user-level applications -and another for kernel-level WAN drivers. WANPIPE is now implemented as a -WAN driver compliant with the WAN Link Driver interface. Also a general -purpose WAN configuration utility and a set of shell scripts was developed to -support WAN router at the user level. - -Many useful ideas concerning hardware-independent interface implementation -were given by Mike McLagan <mike.mclagan@linux.org> and his implementation -of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). - -With the new implementation of the APIs being incorporated into the WANPIPE, -a special thank goes to Alan Cox in providing insight into BSD sockets. - -Special thanks to all the WANPIPE users who performed field-testing, reported -bugs and made valuable comments and suggestions that help us to improve this -product. -

Enable - communications only after all interfaces - come up. HIGH SVC/PVC is used to calculate - the number of channels. - Enable protocol only after all interfaces - are enabled. - - o Added an extra state to the FT1 config, kernel module. - o Updated the pipemon debuggers. - - o Blocked the Multi-Port PPP from running on kernels - 2.2.16 or greater, due to syncppp kernel module - change. - -beta1-2.1.5 Nov 15 2000 - o Fixed the MultiPort PPP Support for kernels 2.2.16 and above. - 2.2.X kernels only - - o Secured the driver UDP debugging calls - - All illegal network debugging calls are reported to - the log. - - Defined a set of allowed commands, all other denied. - - o Cpipemon - - Added set FT1 commands to the cpipemon. Thus CSU/DSU - configuration can be performed using cpipemon. - All systems that cannot run cfgft1 GUI utility should - use cpipemon to configure the on board CSU/DSU. - - - o Keyboard Led Monitor/Debugger - - A new utility /usr/sbin/wpkbdmon uses keyboard leds - to convey operational statistic information of the - Sangoma WANPIPE cards. - NUM_LOCK = Line State (On=connected, Off=disconnected) - CAPS_LOCK = Tx data (On=transmitting, Off=no tx data) - SCROLL_LOCK = Rx data (On=receiving, Off=no rx data - - o Hardware probe on module load and dynamic device allocation - - During WANPIPE module load, all Sangoma cards are probed - and found information is printed in the /var/log/messages. - - If no cards are found, the module load fails. - - Appropriate number of devices are dynamically loaded - based on the number of Sangoma cards found. - - Note: The kernel configuration option - CONFIG_WANPIPE_CARDS has been taken out. - - o Fixed the Frame Relay and Chdlc network interfaces so they are - compatible with libpcap libraries. Meaning, tcpdump, snort, - ethereal, and all other packet sniffers and debuggers work on - all WANPIPE network interfaces. - - Set the network interface encoding type to ARPHRD_PPP. - This tell the sniffers that data obtained from the - network interface is in pure IP format. - Fix for 2.2.X kernels only. - - o True interface encoding option for Frame Relay and CHDLC - - The above fix sets the network interface encoding - type to ARPHRD_PPP, however some customers use - the encoding interface type to determine the - protocol running. Therefore, the TURE ENCODING - option will set the interface type back to the - original value. - - NOTE: If this option is used with Frame Relay and CHDLC - libpcap library support will be broken. - i.e. tcpdump will not work. - Fix for 2.2.x Kernels only. - - o Ethernet Bridgind over Frame Relay - - The Frame Relay bridging has been developed by - Kristian Hoffmann and Mark Wells. - - The Linux kernel bridge is used to send ethernet - data over the frame relay links. - For 2.2.X Kernels only. - - o Added extensive 2.0.X support.

They are included in this release. - -Stable Release -2.2.0 Feb 01 2001 - o Bug fix in wancfg GUI configurator. - The edit function didn't work properly. - - -bata1-2.2.1 Feb 09 2001 - o WANPIPE TTY Driver emulation. - Two modes of operation Sync and Async. - Sync: Using the PPPD daemon, kernel SyncPPP layer - and the Wanpipe sync TTY driver: a PPP protocol - connection can be established via Sangoma adapter, over - a T1 leased line. - - The 2.4.0 kernel PPP layer supports MULTILINK - protocol, that can be used to bundle any number of Sangoma - adapters (T1 lines) into one, under a single IP address. - Thus, efficiently obtaining multiple T1 throughput. - - NOTE: The remote side must also implement MULTILINK PPP - protocol. - - Async:Using the PPPD daemon, kernel AsyncPPP layer - and the WANPIPE async TTY driver: a PPP protocol - connection can be established via Sangoma adapter and - a modem, over a telephone line. - - Thus, the WANPIPE async TTY driver simulates a serial - TTY driver that would normally be used to interface the - MODEM to the linux kernel. - - o WANPIPE PPP Backup Utility - This utility will monitor the state of the PPP T1 line. - In case of failure, a dial up connection will be established - via pppd daemon, ether via a serial tty driver (serial port), - or a WANPIPE async TTY driver (in case serial port is unavailable). - - Furthermore, while in dial up mode, the primary PPP T1 link - will be monitored for signs of life. - - If the PPP T1 link comes back to life, the dial up connection - will be shutdown and T1 line re-established. - - - o New Setup installation script. - Option to UPGRADE device drivers if the kernel source has - already been patched with WANPIPE. - - Option to COMPILE WANPIPE modules against the currently - running kernel, thus no need for manual kernel and module - re-compilation. - - o Updates and Bug Fixes to wancfg utility. - -bata2-2.2.1 Feb 20 2001 - - o Bug fixes to the CHDLC device drivers. - The driver had compilation problems under kernels - 2.2.14 or lower. - - o Bug fixes to the Setup installation script. - The device drivers compilation options didn't work - properly. - - o Update to the wpbackupd daemon. - Optimized the cross-over times, between the primary - link and the backup dialup. - -beta3-2.2.1 Mar 02 2001 - o Patches for 2.4.2 kernel. - - o Bug fixes to util/ make files. - o Bug fixes to the Setup installation script. - - o Took out the backupd support and made it into - as separate package. - -beta4-2.2.1 Mar 12 2001 - - o Fix to the Frame Relay Device driver. - IPSAC sends a packet of zero length - header to the frame relay driver. The - driver tries to push its own 2 byte header - into the packet, which causes the driver to - crash. - - o Fix the WANPIPE re-configuration code. - Bug was found by trying to run the cfgft1 while the - interface was already running. - - o Updates to cfgft1. - Writes a wanpipe#.cfgft1 configuration file - once the CSU/DSU is configured. This file can - holds the current CSU/DSU configuration. - - - ->>>>>> END OF README <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< - - |
