Free gateway software for linux

Gateway is a JavaEE application developed by the Vermont Department of Taxes. It provides a web services framework for accepting Streamlined Sales Tax registrations and returns.

The project also includes a web interface for manually submitting transmissions. The goal is to build an extensible framework upon which future tax services can be built.

Wap-IRC gateway allows you to chat on IRC with any WAP-enabled mobile phone. It works by running the server program on a Unix-like system that is accessible over the Internet. It doesnt require phones which have programs written in Java.
I am Tomas Vilda, student studying at University of Vilnius, Lithuania. I started interested in wap when I bought my first wap enabled mobile phone. I searched for the running irc-wap gateway. But with no success. Actually, I found some, but no such, that I make to connect to specified IRC server. Then I found wapirc gateway written by Alan Cox . I tried it on my FreeBSD server. During compilation I got error, because of bad Makefile. So I compiled it by correcting Makefile and ran successful. My mobile is Siemens C55. To start using this wapirc gateway I have to make some modifications. They are listed below.
Enhancements:
- cgi/main():refresh included into main-cgi, saves us .htaccess and external wmlscript
- cgi/write_wml(): fixed bug in linked nicks with ACTIONs and * in there.
- server/parseinput(): Added /me Command for * ACTION in channels
- cgi/write_card(): get refresh timer from config.h
- server/removeallitems(): doing a list cleanup when disconnecting, so we can rejoin after quit without part
- server/print_out(): screenbuffer with latest messages, scrolling top down
- cgi/write_card(): reload on a regular basis, when not typing something in. New formular works on more phones, informative header
- cgi/wml_link()/wml_header(): wml1.2 compatible links/input field for accesskey element
- cgi/write_wml(): new linewise printout, italic makeup, nicks are linked setting defaultvalues for talking on channels and privat.
- cgi/main(): Expire header
- Makefile: make install

Coherent Mail Gateway is intended to be a very easy to set up MTA using SMTP and POP3. Greylisting is used on the SMTP daemon to reduce spam.

In addition, quite a lot of checks on the validity of information from the SMTP client (such as claimed server name and sender) are carried out, and anyone caught telling lies is disconnected.

Grey-, black-, and white-listing are supported, as well as (optionally) ClamAV and Spamhaus. The target market is users with static IP addresses. Others can use the system, but its value will be limited to outgoing email.

Alamin GSM SMS Gateway provides a SMS-to-SMSQP/SMTP gateway and client to send SMS from an IP client.
Alamin GSM SMS Gateway is a gateway for exchanging messages between GSM and IP networks.
The main objective of the gateway is to provide a reliable delivery service and conversion in both directions in order to extend to the GSM network the functions of IP-based applications.
To make an analogy, its like a web server for HTML pages. They need the web server and provide it with content. The Alamin Gateway paves the way for all types of mobile applications on GSM using SMS messages. One very common use for the gateway is to send an alarm from a computer network to its system administrators. Another is the currently common apps showing tv viewers comments on tv programs.
Currently, the connection to the gateway from the IP network can be achieved using SMSQP (11201), the native protocol of the gateway for sending messages and managing the queue. The SMSQP protocol can be used directly or through the "gsgc" client. Implementing a SMTP interface is easy configuring your MTA for calling a script that prepares the message and calls "gsgc".
The connection between the gateway and the GSM network can be realized through a GSM modem or through a telephone supported by the project Gnokii. A SMPP connector is being developed these days.
At present, only GSM modems can be used in "text" mode. In the future, "pdu" mode will also be supported. Not all devices support both modes, so that you will have to read the manual of your mobile telephone or GSM modem and consult the GSM devices page.
Alamin is developed on Debian GNU/Linux but runs almost in all perl enabled systems.
Enhancements:
- smtp interface has been removed, it was buggy and not fully implemented.
- SMPP interface for sending and receiving messages, both connectors are in own daemons, outside the core module and the message dispatcher.
- SMPP interface uses the Net::SMPP perl module.
- It has been tested onlywith mblox servers.
- MySQL interface for inserting records from received messages and send messages in a table.
- New config files are in perl script format.

Kannel WAP and SMS Gateway project is a WAP and SMS gateway.
SMS, short message services, are widely used all over the world in huge amounts. The main use for Kannel is to link HTTP based services to various SMS centers using obscure protocols.
WAP, short for Wireless Application Protocol, is a collection of languages and tools and an infrastructure for implementing services for mobile phones. Traditionally such services have worked via normal phone calls or short textual messages (e.g., SMS messages in GSM networks). Neither are very efficient to use, nor very user friendly. WAP makes it possible to implement services similar to the World Wide Web.
Unlike marketers claim, WAP does not bring the existing content of the Internet directly to the phone. There are too many technical and other problems for this to ever work properly. The main problem is that Internet content is mainly in the form of HTML pages, and they are written in such a way as to require fast connections, fast processors, large memories, big screens, audio output, and may require fairly efficient input mechanisms. Thats OK, since they hopefully work better for traditional computers and networks that way. However, portable phones have very slow processors, very little memory, abysmal and intermittent bandwidth, little screens and extremely awkward input mechanisms. Most existing HTML pages simply will not work on them.
WAP defines a completely new markup language, the Wireless Markup Language (WML), which is simpler and much more strictly defined than HTML. It also defines a scripting language, WMLScript, which all browsers are required to support. To make things even simpler for the phones, it even defines its own bitmap format (Wireless Bitmap, or WBMP).
HTTP is also too inefficient for wireless use. By using a semantically equivalent, but binary and compressed format it is possible to reduce the protocol overhead to a few bytes per request, instead of up to hundreds of bytes. Thus, WAP defines a new protocol stack to be used. However, to make things simpler also for the people actually implementing the services, WAP introduces a gateway between the phones and the servers providing content to the phones.
The WAP gateway talks to the phone using the WAP protocol stack, and translates the requests it receives to normal HTTP. Thus, the content providers can use any HTTP servers, and can utilize existing know-how about HTTP service implementation and administration.
In addition to protocol translations, the gateway also compresses the WML pages into a more compact form, to save bandwidth on the air and to further reduce the phones processing requirements. It also compiles WMLScript programs into a byte-code format.
Requierments:
- C compiler and development libraries and related tools.
- The gnome-xml (a.k.a. libxml) library, version 2.2.0 or newer. We recommend that you use libxml version 2.2.5. If you are installing it from your distributions packages, youll need libxml2-dev in addition to run-time libxml2 package libraries.
- Note: there is a bug in libxml version 2.2.3 and 2.2.4 that causes problems with character encoding in attributes. This problem is fixed in 2.2.5. See http://xmlsoft.org/xml.html.
- GNU Make.
- POSIX threads (pthread.h).
- GNU Bison 1.28 if you modify the WMLScript compiler.
- DocBook markup language tools (jade, jadetex, DocBook style-sheets, etc; see README.docbook), if you want to format the documentation (pre-formatted versions are available).
Enhancements:
- Various critical bugfixes since 1.4.0, including major SMSC protocols supported (SMPP, EMI/UCP, and GSM AT modem comands), HTTP layer fixes, and WAP WTP and WTP SAR layer fixes.
- The sendsms HTTP interface has been improved to obey the bearerbox message state for replies.
