By "running" I think you mean the machine is licensed for something and could run it. But you get false negatives.

If your company installed everything then you have a very high probability that there is commonality in naming conventions. The default WebLogic owner uid is wls, so if there is a WLS user, apache has to be there as well. Directory names will be there, like for oracle certain lower level names like libclntsh will only exist on a box that can run oracle as either a client or a server, or, /var/opt/oracle/oratab will have entries that end in :Y os :S for boxes that actively run an orcacle database or a standby and so are oracle servers.

Therefore - you need to logically create a set of queries a means of determining, yes this has jboss or not. And the method does not always depend on what users are running but usually depends on what exists in /etc/passwd, /etc/group, /var/opt/... etc.

This is like one of those puzzles where you work out what has to exist by a small numbers of observations. The most dependable are: names of certain files, usernames, some group names, if you are lucky sometimes a daemon with a fixed name will be running full time.

NAME
capisuite - Python-scriptable ISDN telecommunication suite DESCRIPTION
CapiSuite is a Python-scriptable ISDN telecommunication suite. It uses the new CAPI interface for accessing your ISDN-hardware - so you'll need a card for which a CAPI compatible driver is available. Currently these are all cards manufactured by AVM and some Eicon cards. This man page only gives a short introduction, for the real documentation please see the HTML or PDF manual distributed with CapiSuite. CapiSuite tries to give the user the ability to code his own ISDN applications without having to fiddle around with all the dirty program- ming details like callback functions, data buffers, protocol settings and so on. I took a scripting language which is (in my opinion) very easy to understand, to use and to learn - especially for beginners: Python. I extended it with some functions providing the basic ISDN "building blocks" for the users application. Behind these functions the heart of CapiSuite implements all the dirty details a user isn't interested in. My goal was to make script-coding as simple as possible but to also give you the flexibility to realize what you want. To give you an impression, coding a simple answering machine is as easy as:.IP .nf def callIncoming (call, service, call_from, call_to): connect_voice (call, 10) # answer call after 10 secs audio_send (call, "announcemnt.la") # play announcement audio_send (call, "beep.la") # play beep audio_receive (call, "call.la", 10) # record call .fi Of course some details are missing like creating a unique filename or storing the additional information (called and calling party numbers, time, ...) - but I assume you got my idea. And - don't be afraid - if you just want to have a normal answering machine or send and receive some fax documents, you can use the default scripts distributed with CapiSuite. They give you already some nice features - e.g. the answering machine is multi-user ready, supports automatic fax detection and remote inquiry functions. You'll only need to tell CapiSuite some details like your own number, record an own announcement and that's it. So CapiSuite is already equipped for your daily telecommunication needs - but if you don't like to do the things the way I do - just change it or completely do it on your own. And if you write nice scripts or have changes to my default scripts, I would love to get and perhaps make them available for all users if you don't mind. SEE ALSO
