The NKE will only unload when all monitoring connections to it have been stopped. This feature allows you to load a newer version of the NKE without restarting your system. You can try forcing the NKE to unload by selecting "Unload NKE" from the IPNetSentryX application menu. The NKE normally remains loaded until you restart your system since other applications might be using it. When the firewall is disabled, the NKE module is automatically removed from the corresponding data stream. IPNetSentryX uses a Network Kernel Extension (NKE) to intercepts network traffic while the Firewall is enabled. IPNetSentryX takes advantage of Leopard Code signing to alert you of any unintended modifications to the software. The best defense against such exploits at this time is to only run software from reputable developers. Normally allowing small programs to execute as root is not a problem unless the program seeks to compromise your system or is exploited by another program to carry out such an attack. From that point on, no further authentication is necessary to perform any of the restricted operations IPNetSentryX supports. You might think of this as completing the installation process. If any of these tools are not authorized, it asks you to authenticate so it can configure them to run as suid root. The same process is repeated for "RunTCPDump", and "RunTCPFlow".
When IPNetSentryX is first run after being copied to a new location, it checks to see if the LoadNKE tool is present and set to suid root. To monitor network traffic, IPNetSentryX includes a tiny server application named "LoadNKE" that must run as suid root. IPNetSentryX takes the personal computer view that the user should normally be in control of their computer, so tries to minimize the disruption of asking the user to prove they are authorized to perform the requested operation. Among the operations that require such privileges are monitoring all network traffic. While well intentioned, these conventions are often inappropriate for a "personal" computer where a single user owns and administers the system.

Under UNIX operating systems including Mac OS X, certain operations require special permission or privileges to prevent unauthorized users from disrupting or spying on other users. The first time IPNetSentryX is run it will ask you to authenticate to complete the installation process.
Ipnetsentryx install#
To install or remove the software, simply drag a copy to your hard drive.
Ipnetsentryx mac os x#
Mac OS X Leopard requires version 1.5.1 or later. Mac on Intel requires version 1.5 or later. Version 1.7 Requires Mac OS X 10.4 (Tiger) or later. Version 1.4 Requires Mac OS X 10.3.9 (Panther) or later. Version 1.3.1 Requires Mac OS X 10.2 (Jaguar) or later. The simple well organized display with built-in examples allowĪnd experienced Internet users to benefit from a powerful firewall
