Abstract
A method is provided for intercepting network packets in a computer system, where a number of functions are used to communicate network packets between a network adapter and a protocols entity. A first network adapter and a first protocols entity installed in the computer system are identified. A set of replacement functions is provided within a packet interceptor module. At least one function used for transmitting network packets from said first protocols entity to said first network adapter is hooked into a first replacement function. At least one function used for transmitting network packets from said first network adapter to said first protocols entity is hooked into a second replacement function. At least one function used for receiving information about the status of the network interface implemented by said first network adapter is hooked into a third replacement function.
