Guarddog is a firewall configuration utility for Linux systems. It is aimed at two groups of users. Novice to intermediate users who are not experts in TCP/IP networking and security, and those users who dont want the hastle of dealing with cryptic shell scripts and ipchains/iptables parameters.
Main features:
- Easy to use goal oriented GUI. You say what the firewall should do without having to explain all the details of how it should do it.
- Application protocol based. Unlike other tools, Guarddog does not require you to understand the ins and outs of IP packets and ports. Guarddog takes care of this for you. This also reduces the chances of configuration mistakes being made which are a prime source of security holes.
- Doesnt just generate the firewall once and forgets it. Guarddog lets you maintain and modify the firewall in place.
- Hosts/networks can be divided into Zones. Different zones can have different security policies for different.

GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the two most widely-used Internet protocols.
It is a non-interactive commandline tool, so it may easily be called from scripts, cron jobs, terminals without Xsupport, etc.
Main features:
- Can resume aborted downloads, using REST and RANGE
- Can use filename wild cards and recursively mirror directories
- NLS-based message files for many different languages
- Optionally converts absolute links in downloaded documents to relative, so that downloaded documents may link to each other locally
- Runs on most UNIX-like operating systems as well as Microsoft Windows
- Supports HTTP and SOCKS proxies
- Supports HTTP cookies
- Supports persistent HTTP connections
- Unattended / background operation
- Uses local file timestamps to determine whether documents need to be re-downloaded when mirroring
- GNU wget is distributed under the GNU General Public License.
Enhancements:
- A buffer overrun in the NTLM code was fixed.

Gpremacy is a Mono/Gtk# clone of the 80s board game "Supremacy" by Supremacy Games, Inc. Gpremacy is a "Risk"-like game set in the near future between the superpowers with macroeconomics and nuclear weapons.
Main features:
- Cross Platform: Will run on any system supported by Mono (Win2k+, Linux, Solaris, OS X...)
- Multiplayer Ready: Play with your friends online, and nuke them!
- AI in development: If you dont have enough people, or just want to play by yourself. Look for this soon!
- Theme-ready: Gtk themes are automatically applied, so it can match your furniture and socks!

Dante is a circuit-level firewall and proxy that can be used to provide convenient and secure network connectivity to a wide range of hosts while requiring only the server Dante runs on to have external network connectivity.
Once installed, Dante can in most cases be made transparent to the clients while offering detailed access control and logging facilities to the server administrator.
Developed by Inferno Nettverk A/S, Dante usually comes installed as part of a bigger Inferno Nettverk firewall system. Inferno Nettverk has however decided to also offer it separately available via FTP. The Dante version provided via FTP is under a BSD/CMU-type license and comes with complete source code, for your convenience and verification.
Inferno Nettverk also provides commercial services related to Dante. These services include support, customised installations/tuning of Dante, development, porting and embedding.
Enhancements:
- This version has partial support for server chaining and a new module for controlling sessions.
- Bugfixes include several corrections to handling of PAM-based authentication.

prtunnel is a program that can tunnel TCP/IP connections in a variety of ways, including through HTTP and SOCKS5 proxy servers. Some if its possible uses include:
- Tunneling TCP connections from client programs to a remote server through an HTTP or SOCKS5 proxy (useful if youre behind such a proxy and want to use a program that doesnt have native proxy support)
- Tunneling TCP connections from SOCKS-capable client programs through an HTTP or SOCKS5 proxy
- Tunneling TCP connections from an IPv4 client program to an IPv6 server and vice-versa
- Forwarding TCP connections
- Running as a simple SOCKS proxy server
prtunnel project was developed and used under Linux and BSD-based operating systems.
Enhancements:
- A bug that would cause malloc(0) to be called in some situations (which could cause problems on some systems) has been fixed.
- The server timeout, if specified, is now set before the proxy server successfully connects to the remote server, which will prevent the program from hanging if the proxy does not respond to the client.
