  The analysis of the X-ray data for a sample of 51 LINER nuclei with available
X-ray Chandra imaging is reported. Our aim was to investigate the physical
mechanisms which power LINER nuclear activity. The use of multiwavelenght
information at radio, UV, optical HST and X-ray lead us to conclude that at
least 60% of the LINERs are hosting a low luminosity AGN in their nuclei. This
percentage may be even higher if the Compton-thickness of some nuclei (mostly
with SB-like hard X-ray morphology) is confirmed.
