  We review recently developed models of galactic discrete sources of high
energy neutrinos. Some of them are based on a simple rescaling of the TeV
$\gamma$-ray fluxes from recently detected galactic sources, such as,
shell-type supernova remnants or pulsar wind nebulae. Others present detailed
and originally performed modeling of processes occurring close to compact
objects, i.e. neutron stars and low mass black holes, which are supposed to
accelerate hadrons close to dense matter and radiation fields. Most of the
models considered in this review optimistically assume that the energy content
in relativistic hadrons is equal to a significant part of the maximum
observable power output in specific sources, i.e. typically $\sim 10%$. This
may give a large overestimation of the neutrino fluxes. This is the case of
models which postulate neutrino production in hadron-photon collisions already
at the acceleration place, due to the likely $e^\pm$ pair plasma domination.
Models postulating neutrino production in hadron-hadron collisions avoid such
problems and therefore seem to be more promising. The neutrino telescopes
currently taking data have not detected any excess from discrete sources yet,
although some models could already be constrained by the limits they are
providing.
