Free gateway software for linux

Creates indexed pdf documents from text files. Designed to aid creating an electronic distribution method for legacy system reports, since many mainframe type print spools are plain text.
Allows indexing, customizing page settings, font size, font face, and super-imposing text over an image in the case of using pre-printed forms. Supports unlimited levels of indexing bookmarks in documents and system/user configuration files.
Suitable for use in an intranet gateway for generating PDF documents in real-time.
Enhancements:
- This fixes a bug for page breaking when the number of lines is a multiple of the lines per page, thanks to Carlo Benna

The RSS-IM Gateway allows any site with an RSS feed to make their feed available via the IM network of their choice. It is very easy to set up.
Just create a new IM nick on your favorite network (links here) - something like "MySiteIM" always works - fill out the blanks in the config.im file, and your headlines are viewable on that network automatically, including from most cell phones if you use AIM or MSN. It works with AIM, ICQ, YIM and Jabber.
This project is a derivative of the SDBA Revolution IM Application Server version 1.85 and includes all files you will need. You will need to have an uptodate version of Perl with XML::RSS, in addition to the other libraries required.
Using:
- Make sure Perl is set up correctly, with all libraries (including XML::RSS!).
- Open config.im and put in your chosen nick and password for the bot, edit the network (default is AIM), and put in the URL to your feed.
- Start sdba.pl from the command line.
- Message the nick you chose from any IM client.

netGo is a distribution-independent networking tool (written in Qt) for changing network settings quickly and easily. It is intended for laptop owners, who often need to change network settings when relocating.
It allows you to create profiles that contain the network settings such as the IP, netmask, gateway, name servers and wireless options. After creating a profile it can be executed with a single click.
netGo is distributed under the terms of the GPL-license.
Main features:
- Configure an interface with static IP, netmask, gateway and nameservers.
- Configure an interface using DHCP.
- Configure an interface using wireless options.
- Execute a profile from the commandline - without GUI.
- System tray support (works in KDE, Gnome, xfce etc).

GoVPN project is an OpenVPN frontend for GNU/Linux operating systems, developed in Gambas.

To make it easier for non-technical users, weve built a userinterface for OpenVPN on linux.

If administrators send configuration files to the user, (s)he will be able to install and connect to the corporate OpenVPN gateway.

autonet.py is a small application which looks up existing network configuration files, probes the network with arping in order to determine if it can connect and ideally set up a working internet connection and routing.

If no internet connection is available, autonet.py will parse each configuration file, extract different network setups and probe if the network environment works with this configuration.

The probing is done with arping. A bogus IP 0.0.0.0 is used in order to get the network interface up. Then autonet.py tries to arping the gateway.

If the gateway responds the configuration is considered good. At this point there is no routing, so only hosts within the subnet defined in the configuration is used.

If none of the gateways in the configuration works, the probe gets more brutal by just setting up the network interface according to the configuration file, and and ping the gateway. Again, no routes yet.

If a configuration is considered working (gateway is pingable), the route is set as described in the configuration file. An internet connection should be established then.

This is also checked by pinging k.root-servers.org (as default, override with --testhost), use an IP address here, as DNS is not handled by autonet (yet?).

There is a special feature in autonet.py for owners of some models of Asus notebooks. The package contains a module which uses two LEDs of the laptop to show activity.

While searching and probing, the blue LED is flashing, if a working configuration is found the orange LED flickers for a second. Also this will only work if you have the asus module in your kernel, and it has *not* widely been tested. Have a look at Asus.py for details.

Some common vars can be edited in autonet.py, such as locations of required programs and some common settings (of which timeout does not even work yet) but in most cases supplying reasonable commandline arguments should be sufficient.

As Gentoo has slightly different settings, there are two scripts for Gentoo users, to make integration into the Gentoo init system easier.

FIDOGATE is a Fido-Internet gateway and a Fido tosser.
Main features:
- Fido Internet Gateway
- Fido Zone Gateway (NetMail zone gate)
- Fido Tosser (mail processor)
- Fido Ticker (file processor)
- Fido Areafix and Filefix

Fiked is a fake IKE daemon that supports just enough of the standards and Cisco extensions to attack commonly found insecure Cisco PSK+XAUTH VPN setups in what could be described as a semi-MitM attack.
Basically, knowing the pre-shared key, also known as shared secret or group password, the VPN gateway can be impersonated in IKE phase 1, in order to learn XAUTH user credentials in phase 2.
The configuration supported by fiked is IKE aggressive mode using pre-shared keys and XAUTH. FakeIKEd supports algorithms like DES, 3DES, AES128, AES192, AES256, MD5, SHA1, and DH groups 1, 2, and 5. Main mode is not supported.
Basically, if you know the pre-shared key, also known as shared secret or group password, you can play Man in the Middle, impersonate the VPN gateway in IKE phase 1, and learn XAUTH user credentials in phase 2.
This attack is not new. It has been known for a long time that IKE using PSK with XAUTH is insecure, and this is not the first actual implementation of the attack.
To successfully demostrate an attack on a VPN site, you need to know the shared secret, and you must be able to intercept the IKE traffic between the clients and the VPN gateway.
There are several ways to find out the shared secret, including being a legitimate user, grabbing it from some Cisco config file, using ike-crack, or layer 8 hackery.
There are also several ways to redirect the IKE traffic to your running fiked instance, including ARP spoofing, 802.11 hostap, or layer 1 hackery.
Usage:
Usage: fiked [-rdqhV] -g gateway -k id:psk [-k ...] [-l file] [-L file]
-r use raw socket: forge source address to match < gateway >
-d detach from tty and run as a daemon (implies -q)
-q be quiet, dont write anything to stdout
-h print help and exit
-V print version and exit
-g gw VPN gateway address to impersonate
-k i:k pre-shared key aka. group password, shared secret, prefixed
with its group/key id (first -k sets default)
-l file append results to credential log file
-L file verbous logging to file instead of stdout
Enhancements:
- Bugfixes, portability changes, and support for dropping privileges.
