IBM 3270 Terminal Applications suite consists of seven applications.
x3270 is an IBM 3270 terminal emulator for the X Window System and Windows. The project runs on most Unix-like operating systems -- e.g., Linux, Mac OS X, Solaris and Cygwin. It also runs natively on Windows.
x3270 runs over a TELNET connection, emulating either an IBM 3279 (color) or 3278 (monochrome). It supports:
- The full TN3270E protocol
- SSL/TLS (via the OpenSSL library) for encrypted sessions
- APL2 characters
- Non-English character sets, including Russian, Turkish, Hebrew and DBCS Chinese and Japanese
- IND$FILE file transfer
- NVT mode (emulating a color xterm)
- A pop-up keypad for 3270-specific keys
- A scrollbar
- Printer session integration
- Extensive debugging and scripting facilities
It does not yet support graphics. x3270 is distributed as source code, and can be used for free.
- x3270 is available in several different forms:
- x3270 is for use on an X graphics display
- c3270 is a curses-based version for use on a dumb terminal (e.g., a serial terminal or a Linux console)
- wc3270 is the Windows console version of c3270
- s3270 is a displayless version for writing screen-scraping scripts
- tcl3270 is similar to s3270, but integrated with Tcl
- pr3287 is for printer emulation
- wpr3287 is the native Windows version of pr3287
Also available is x026, an IBM 026 Keypunch emulator.
Enhancements:
- Proxy support was added.
- 3270 background color was added to c3270 and wc3270.
- Numerous small bugs were fixed.

The Zaval Proxy Suite is an easy-to-use solution that allows monitoring TCP-based protocols, such as HTTP, NNTP and others. It is extremely useful in software development and can be used as a debug tool. Another area of appliance is multiple connections logging with proxy facilities. As soon as its a pure java solution it can be used almost everywhere.

The Zaval Proxy functions as a proxy and transfers data between the server and the client writing incoming and outgoing traffic into log files. So you can see these raw data as is.

On start the Zaval Proxy Suite goes through configuration file and creates the specified number of proxy servers and the shutdown server.

"Proxy server" is a server socket listening on the specified port. When the client is connected proxy connects to the target server and transfers data between them logging entire traffic. On each connection 2 files are created - xxx-input (request data from the client) and xxx-output (response data from the server). The "xxx" means here the sequential number of the connection for the proxy server. The traffic is logged into the separate directory for each proxy.

Shutdown server is needed to close all open connections correctly and close the program.

So, in the particular case you should specify address of proxy server in client application (web browser, for example) and address of the target server in the proxy configuration file. You can create any number of proxy servers that run at the same time, however, they should use different port numbers.

SAP R/3 Communications Suite allows SAP R/3 servers to communicate with external devices such as fax and GSM modems by sending and receiving a fax or SMS.

SAP R/3 Communications Suite provides an easy configuration through a Web interface and a JMX console.

Buni Meldware Communication Suite (MCS) is a platform-independent groupware package consisting of:
- Meldware Mail
- Meldware Calendar
- Meldware Webmail
- Meldware Secure Administration System
Together the package provides support for thousands of users concurrently to send and receive email and to schedule meetings. MCS uniquely allows you to store all messages and scheduling events in nearly any database and runs on nearly all popular software and hardware platforms.
MCS commitment to platform and database agnosticism aims to meet increasing business requirements to maximize ease and flexibility of managing and accessing data as well as putting a premium on interoperability.
Additionally, while the scheduling and calendaring services can be installed separately, the integrated feature set provides both a distinctive and powerful experience to both users and server-side Mail Based Applications and Collaboration Based Application Services.
The MCS platform provides security integration using LDAP sources including Microsoft Active Directory as well as flat-file and database sources.
Additionally, extensible security allows custom authentication/authorization sources.

Openwall tcb suite package contains core components of our tcb suite implementing the alternative password shadowing scheme on Owl.

It is being made available separately from Owl primarily for use by other distributions. Note that you need to have the password hashing framework introduced with crypt_blowfish patched into glibc to compile and use this.

The package consists of three components: pam_tcb, libnss_tcb, and libtcb.
pam_tcb is a PAM module which supersedes pam_unix. It also implements the tcb password shadowing scheme.

The tcb scheme allows many core system utilities (passwd(1) being the primary example) to operate with little privilege. libnss_tcb is the accompanying NSS module. libtcb contains code shared by the PAM and NSS modules and is also used by user management tools on Owl due to our shadow suite patches.
