TCPBlock FOR MAC

TCPBlock is a lightweight and fast application firewall for Mac OS X 10.5 or later developed by delantis.com.

Description:

The Mac OS X firewall protects you from connections that come from outside of your computer. But what about the software from your computer that opens new connections to the internet? With TCPBlock, you can prevent selected applications on your computer from opening connections to the network.

Implemented as a loadable kernel module, TCPBlock contains all the blocking logic. You can configure it in the System Preferences TCPBlock preference pane or with the tcpblock command line utility. All configuration changes are persistent in a file on the hard disk.

Features:

• Lightweight and fast application firewall


• Configurable in System Preferences TCPBlock preference pane


• Loadable kernel module with blocking logic


• Prevent selected applications from opening connections to the network


• Configuration changes are made persistent on the hard disk

Usage:

In System Preferences, open the TCPBlock preference pane where you can choose to enable the firewall, block all connections to the network, and specify if your application list is a black list or a white list. Use the + button to add new applications to the list by typing the Unix command name of the application.

Note that the Mac OS X kernel uses only the first 16 characters of the command name for name comparisons, truncating any characters above this limit. Monitor TCPBlock activities using the command line client.

Configuration:

The TCPBlock configuration is stored in a file on the system and can be edited to load changed configurations. This file is overwritten if you configure TCPBlock using the preference pane or the tcpblock utility.
