this is an interesting term in Buddha Dharma.
Samadhi is a Sanskrit term which means, literally, "to establish or make firm". so, what is being alluded to here is a firmness of mind which is often likened to a single pointed concentration upon a given phenomena.
there are various stages of Samadhi or mental absorption, with the highest being Nirvikalpa-samadhi. when the Buddha Dharma talks about the Jhannas, this is what they are referring to. the Jhannas are the various levels of consciousness which can be acessed through the process of meditation and correspond to certain insights and realizations through the path.
How does one attain Samadhi?
through the process of meditation. Buddhism has two forms of meditive practice, generally, which are called Samatha and Vipassana, calming and insight. what raffster is referring to is part of the Samatha meditation, the calming the mind. in the Suttas, Buddha Shakyamuni advises that the use of the "watching the breath" meditation is the most expedient. once the mind is calm, it can then be turned to Insight into the nature of phenomena or what ever the object is of the meditation.
How does one know when they have attained Samadhi?
Samadhi is not the goal, so there isn't much value in trying to work for the attainment of it, per se. that said, it is through Samadhi that one can engage in the Insight meditation which leads to the higher absorptions in the Jhannas. the Jhannas are, for all intents and purposes, way stations along the path. places to rest whilst planning the next part of the journey.
in point of fact, the attainment of the various powers in Buddhism come through realization and absorption in the Jhannas, the ability to recall all previous arisings, the ability to know the thoughts of others and so forth.
i suppose that the easiest answer to your query is thus:
once you, yourself, have tasted the water; you will know if it is warm or cool.
metta,
