Free wpa software for linux

wpa-buddy is a tool to decrypt WPA-PSK protected traffic, given the passphrase. wpa-buddy project can work in real-time (sniffing packets from a network interface) or in batch mode (reading packets from a capture file).

It also produces nice output telling you whats going on. wpa-buddy currently supports WPA and WPA2 (this last only in the unstable version).

WEP Key Changer project, in short WepKC is a client/server application that allows you to protect your ad-hoc (point to point) wireless network when you are unable to use (due to software or hardware limitations) sophisticated protocols like WPA.

The program consists out of two parts:

the wepkcd daemon, which randomly changes the WEP key after a specified amount of time and sends the chosen key, encrypted with AES, to the wepkcc client
the wepkcc client, which receives the key through the encrypted channel and changes the WEP key in the client machine

The server also waits for packets ("pings") from the client, resetting the WEP key to a defined value when the client goes down and stops pinging the server.

If someone tries to use the wireless network without contacting the server, the connection will be dropped repeatedly in order to prevent further annoyance from strangers (please note that this feature, at the moment, works only in *nix systems).

And its very easy to setup and use.

KNetworkManager is the KDE front end for NetworkManager. KNetworkManager project provides a sophisticated and intuitive user interface which enables users easily to switch their network environment.

The range of functions encompasses the features implemented by NetworkManager daemon. Up until now NetworkManager supports:

Wired Ethernet Devices (IEEE 802.3)
Wireless Ethernet Devices (IEEE 802.11): Unencrypted, WEP, WPA Personal, WPA Enterprise
Virtual Private Network (VPN): OpenVPN, VPNC
Dial-Up (PPP)

How does it work?

For both, Wireless LAN and Wired LAN, NetworkManager supports devices known to HAL. Unless working in offline mode, NetworkManager tries to keep the system connected at any time. For this, NetworkManager follows the following policy.

Once started, NetworkManager asks HAL about available network interfaces. If a wired network interface with a carrier is found, NetworkManager connects to this. Either by DHCP (default) or by setting up previously defined static configuration. Later on, when KNetworkManager starts up, NetworkManager will expose its information about network devices and wireless networks found by scanning to the applet.

At this point, if a user decides to unplug the wired connection, NetworkManager will not connect to an arbitrary wireless network. By default all available networks are untrusted. Only if a user decides to connect to a network manually once, this specific network n henceforth being marked as trusted.

n = { ESSID, Hardware address or addresses of the access point}

The trusted networks are stored individually for each user. KNetworkManager stores them and informs NetworkManager about the known, trusted networks. If a wired connection drops due to unplugging the cable NetworkManager will automatically connect to a trusted network. As this step was done without user interaction, NetworkManager will reconnect to the wired connection once it has a carrier.

If a user joins a wireless network by manual intervention (e.g. user clicks on a network listed in the context menu of KNetworkManager or connects to a hidden wireless network), NetworkManager will take down any previous connection. If one unplugs the wired connection after such a step, NetworkManager will not connect to the wired connection once it has a carrier.

This is a small application allowing you to scan for wireless networks and connect to them.
Wireless Assistant uses wireless-tools as its backend, so they need to be installed.
All feedback as well as hints and good advice are appreciated!

phpRADmin is a Web tool to allow administration, configuration, and provisioning of a RADIUS server (FreeRADIUS), clients (NAS, AP, etc.), and users (PPP, PPPoE, EAP, etc.) with MySQL as the backend.

This interface (including dialup_admin) allows the administrator to config, find, create, edit, delete, and test users on an SQL (MySQL) database, create SQL groups, gather accounting information for a user, do complicated queries on the SQL accounting database, check RADIUS server availability, and produce dialup usage statistics, manage (create, update, revoke) PKI Certificates, Dictionary management, invoice management and system monitoring.

Really, a system to manage FreeRADIUS with WPA, EAP (802.1X), PPP, PPPoE, Captive Portal, VoIP systems and other authentication methods. phpRADmin show pies and graphs of your network status, usage audits, administration profiles with 3 levels. phpRADmin is Chillispot and WISP ready.

This is a Linux driver for wireless LAN cards based on Intersils Prism2/2.5/3 chipset. The driver supports a so called Host AP mode, i.e., it takes care of IEEE 802.11 management functions in the host computer and acts as an access point.
This does not require any special firmware for the wireless LAN card. In addition to this, normal station operations in BSS (infrastructure) and in IBSS (ad hoc). Current version of the Host AP driver and tools supports WPA in AP (Authenticator) and client (Supplicant) modes.
Intersils station firmware for Prism2/2.5/3 chipset supports a so called Host AP mode in which the firmware takes care of time critical tasks like beacon sending and frame acknowledging, but leaves other management tasks to host computer driver.
Main features:
This driver implements basic functionality needed to initialize and configure Prism2/2.5/3-based cards, to send and receive frames, and to gather statistics. In addition, it includes an implementation of following IEEE 802.11 functions:
- authentication (and deauthentication).
- association (reassociation, and disassociation).
- data transmission between two wireless stations.
- power saving (PS) mode signaling and frame buffering for PS stations.
The driver has also various features for development debugging and for researching IEEE 802.11 environments like access to hardware configuration records, I/O registers, and frames with 802.11 headers.
Enhancements:
- fixed background scans (iwlist wlan0 scan) not to break data connection when in host_roaming 2 mode (e.g., when using wpa_supplicant)
- fixed beacon frame when moving from monitor mode to master mode (workaround for firmware bug that left IBSS IE in the Beacon frames)

Raw Fake AP is a program that emulates valid IEEE 802.11 access points using wireless raw injection.
Raw Fake AP application aims to create both beacon and probe response frames and could be used to "hide" real networks from novice wardrivers or for testing wireless intrusion detection systems.
Main features:
Overall features:
- Raw injection of beacon and probe response frames in monitor mode
- Try to forge coherent sequence numbers and BSS timestamps (depending on driver injection capabilities)
- Try to have a coherent time interval between beacons (which is hard to achieve without a real time kernel)
Command line interface will help you to choose between:
- Randomize Open/WEP/WPA/RSN crypto
- Randomize b/g cards
- Channel hopping
- TXpower hopping
- Randomize ESSIDs (alnum or not)
- Randomize BSSIDs
- Choose beacon interval
- Choose number of fake access points
- Choose a file with valid OUIs
- Choose a file with ESSIDs
- Choose between beacon or probe response frames
- Select a destination MAC address

CheckAccess is a PHP script to build a report of logins into a server. It could be useful to system administrator to search for unathorized logins into their systems.
The project supports now these services: openssh, proftpd, popa3d, ipop3d, dovecot.
Enhancements:
- This release adds support for Freeradius (wpa eap-tls) log reporting.
