Personally I like the opinion of nuxwin - every admin should know which services should run and which should not.
But - then we may also write all services in the same color, just the last column should state "up" or "down" (Port open/closed etc).
If we consider marking a line red or green then we should let the admin decide which service should run and which not and depending on this the gui uses the color... so we should add a "should-state" in the port list/services list....
What do you guys think?
