Systems and methods configuring a process that uses IPv4 communication without associating the IPv4 process with an IP loopback address are disclosed. Embodiments may include receiving a message to configure an IPv4 process. Embodiments may also include determining if a configuration parameter associated with the received message is set to indicate that one or more default IP loopback addresses are to be used as IP loopback addresses to associate with the IPv4 process. Embodiments may further include completing the configuration of the IPv4 process without associating an IP loopback address with the IPv4 process when the configuration parameter is determined to not be set to indicate that one or more default IP loopback addresses are to be used as IP loopback addresses to associate with the IPv4 process.

A pseudo-random generator may be used to generate identification values for formatted data packets. A method for transmitting data less susceptible to man-in-the-middle attacks may include receiving data for transmission over a network according to a protocol; formatting the data into one or more internet protocol (IP) packets by fragmenting the received data; and transmitting the one or more internet protocol (IP) packets. The step of formatting the data into one or more internet protocol (IP) packets may include generating a unique pseudo-random number while avoiding collisions with previously-used numbers; and inserting the pseudo-random number as an identifier in the one or more internet protocol (IP) packets corresponding to the received data.

Avoiding collisions in internet protocol (IP) packet identification numbers

A fast send method may be selectively implemented for certain data packets received from an application for transmission through a network interface. When the fast send method is triggered for a data packet, the application requesting transmission of the data packet may be provided a completion notice nearly immediately after the data packet is received. The fast send method may be used for data packets similar to previously-transmitted data packets for which the information in the data packet is already vetted. For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. A socket table may be maintained listing previously-transmitted data packets and an instruction for handling additional data packets similar to the data packet entered in the socket table.

A server system may be configured to receive configuration information. The server system may also be configured to determine if the configuration information includes SNMP configuration information. The server system may be further configured to disable SNMP activity and close an SNMP port if it determines that the configuration information does not include SNMP configuration information. Therefore, in the absence of any configuration information which specifies that SNMP should be available, SNMP activity is disabled and the SNMP port is closed.

Control of simple network management protocol activity

A fast send method may be selectively implemented for certain data packets received from an application for transmission through a network interface. When the fast send method is triggered for a data packet, the application requesting transmission of the data packet may be provided a completion notice nearly immediately after the data packet is received. The fast send method may be used for data packets similar to previously-transmitted data packets for which the information in the data packet is already vetted. For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. Data packets sent through the fast send method may be throttled to prevent one communication stream from blocking out other communication streams. For example, every nth data packet queued for the fast send method may be transmitted by a slow send method.

Method and apparatus for an application program running on a Web browser to make service requests to a service routine running on an On-Line Transaction Processing (OLTP) system. When the application program requests a service on the OLTP system, the input data format required for the requested service is passed to the application program. The application program submits a service request to the service routine in the input data format, and receives a result of the service routine processing the service request in the output data format. The input and output data formats allow the application program to complete additional processing of the result in the output data format and make subsequent service requests to the OLTP system.

Apparatus and method which allows a user to dynamically gather Web Site status information from a Web Browser. In a preferred embodiment, the present invention allows a user to gather information on which Web Pages within a Web Site have been recently updated. The present invention utilizes a workstation-based custom gateway to interconnect a user's Web Browser to the Web Server which hosts the Web Site. This gateway includes a program which receives a user-tailorable search request from a Web Browser, traverses a portion of the Web-accessible file structure of the Web Server, identifies Web Site files which meet the search request criteria, builds a table of results from the search, and returns the search results to the Web Browser. The present invention also allows an administrator to customize the table of results returned to the Web Browser.
