Theres essentially no way to provide a comprehensive list. Different systems will have different services running by default, even between different service pack versions of MS Windows XP, and if youre coming into a situation where you must assume responsibility for the security of computers that were already set up before you got there, there are certain to be different services running than on a default install of the system. Worse, there are new services being invented from time to time, expanding the number of services that may possibly be running on a given computer. Whats needed is a tool for listing active services and open ports. Ill explain how such tools can be used on three types of systems, in alphabetical order Linux distributions, Free. BSD, and MS Windows plus how to use an additional tool for commercial UNIX systems where the other tools may not be available. Free. BSD On a Free. BSD Unix system, as with other BSD Unix systems, you have a number of utilities with a base system install that can be used for listing open files, running processes, and network connections.
