    AutoAP

    A script to find open Wi-Fi connections and the strongest signal

    AutoAP is a script that continuously scans for open Wi-Fi connections, tests them for validity, and connects to the strongest signal. If the connection is lost, the script scans again and finds the strongest valid signal again, and maintains a continuous connection to the internet in a mobile or portable environment. The script paremeters are highly configurable, including ability to configure secure connections. AutoAP is an add on to DD-WRT that allows routers to continuously scan for and connect to open (and predefined WEP) wireless networks. Ultimately the goal is to develop an easily deployable firmware that facilitates fast and easy mesh network creation. Typically, you would use this script on your router while in Repeater Mode, Client Mode, or Client-Bridged Mode.

    OpenSnitch

    OpenSnitch

    OpenSnitch is a GNU/Linux port of the Little Snitch firewall

    OpenSnitch is a GNU/Linux port of the Little Snitch firewall. You can launch the GUI from the icon or from the system menu. The daemon will start intercepting connections, prompting you to allow or deny them. If you don't apply an action, after 15 seconds (configurable) it'll apply the default action configured. When you open the GUI, you'll see all the connections and processes that the daemon has intercepted. Double click on a row to view the details of a process, rule, host or user. Once you know which are the common processes, IPs and hosts that your machine is connecting to, you can start creating permanent rules (Duration: always) to deny or allow them. You can also convert temporary rules to permanent by right-clicking on a temporary rule or by double-clicking on it, and then edit it. By default OpenSnitch UI listens on a local Unix socket in /tmp/osui.sock.
