  • Patent number: 7277937
    Abstract: A system is provided for executing a system call originating in a local computer on a first remote computer connected to the local computer via a network. Communication is established between the local computer and the first remote computer via the network. A syscall server is installed in the first remote computer. A reference address is sent from the first remote computer to the local computer via the network through execution of code by the syscall server. A syscall request is built in the local computer with arguments determined using the reference address received from the first remote computer. The syscall request is sent from the local computer to the first remote computer via the network. The syscall request is copied into a stack of the first remote computer through execution of code by the syscall server. Registers are popped from the syscall request in the stack. Execution of a syscall request is initiated on the first remote computer. The result of the syscall request is pushed onto the stack.

  • Patent number: 6687833
    Abstract: A system and method for providing a network host decoy on a virtual host using a pseudo implementation of a network protocol stack are described. A hierarchical network protocol stack is functionally defined and includes a plurality of communicatively interfaced protocol layers. A request frame originating from a remote host is received. The request frame includes a plurality of recursively encapsulated data segments which each correspond to a successive protocol layer in the network protocol stack. At each protocol layer, processing a header associated with the encapsulated data segment demultiplexs each encapsulated data segment in the request frame. Any requested network service is performed and any recursively encapsulated portion is forwarded to the next successive protocol layer. A plurality of pseudo data segments corresponding to each of the protocol layers in the network protocol stack is formed. Each pseudo data segment includes a header and data portion.
