Contextual communication and service interface

In the classification phase, proxy servers 312 may further probe each discovered device to determine the version of its operating system. The probes used for a particular device are based on information gathered about the devices during the scanning phase. For example, if a device is found with TCP port 22 open, a set of UNIX?-specific probes may be used. Likewise, if a device is found with TCP port 135 open, a set of WINDOWS?-specific probes may be used. For either case, an appropriate set of tasks may be placed in task list 502 for proxy servers 312 to carry out. These tasks may result in proxy servers 312 logging on, or otherwise accessing information from the particular device. For instance, if TCP port 22 is open, proxy servers 312 may be instructed to initiate a Secure Shell (SSH) connection to the particular device and obtain information about the operating system thereon from particular locations in the file system. Based on this information, the operating system may be determined. As an example, a UNIX? device with TCP port 22 open may be classified as AIX?, HPUX, LINUX?, MACOS?, or SOLARIS?. This classification information may be stored as one or more configuration items in CMDB 500.
