Abstract
In accordance with one aspect of the embodiments of this invention there is a method to operate a network mapping tool. The method includes performing a network mapping operation over a first set of ports to generate a list of hosts that are found to be alive; performing a sequential scan on only those hosts in the list to detect the operating system of each host in the list; and performing a parallel port scan to detect characteristics of only those hosts in the list. The characteristics can include an identification of at least applications and services running on the hosts in the list. The second set of ports can be a full set of ports.
Claims15
A method to operate a network mapping tool, comprising:
- performing a network mapping operation over a first set of ports to generate a list of hosts that are found to be alive;
- performing a sequential scan on only those hosts in the list to detect the operating system of each host in the list;
- and
- performing a parallel port scan to detect characteristics of only those hosts in the list.
A computer-readable storage medium having computer-executable program code stored thereon or therein, execution of the program code resulting in operation of a network mapping tool, comprising operations of:
- performing a network mapping operation over a first set of ports to generate a list of hosts that are found to be alive;
- performing a sequential scan on only those hosts in the list to detect the operating system of each host in the list;
- and
- performing a parallel port scan to detect characteristics of only those hosts in the list.
A system comprising at least one computer coupled with at least one memory containing computer-executable program code stored thereon or therein, the at least one computer being coupled with a data communications network and the execution of the program code resulting in the system operating a network mapping tool, comprising:
- performing a network mapping operation over a first set of ports to generate a list of hosts that are found to be alive;
- performing a sequential scan on only those hosts in the list to detect the operating system of each host in the list;
- and
- performing a parallel port scan to detect characteristics of only those hosts in the list.
