Where'd they go ?

[Mike Medai]

Back to playing around with my linux box and I've installed Etheral and 
traffic-vis (from Suse 9.0 source CD's using Yast) to see how they work 
and to see what is going on with my little home network.

But now I can't find the programs.  So, now comes the multi-part question ..

How do I go about finding where things get installed, both command line 
and using KDE?  And how to start them if they don't "magically" appear 
in the "start applications" pop-up menu that KDE has provided (and which 
is driving me nuts as I next plan on rearranging that darn thing properly)?

How does one determine whether a particular program is meant/designed 
for a GUI interface or a command line interface (the obvious Kxxxxx 
doesn't count)?  I've sorted out that when downloading from the 'net, if 
the program is written for X, then it essentially has a GUI interface.  
But that doesn't crop up on the source cd's.

Thanks.

Mike
