logparse / parsers / smbd.pyon commit bugfixing & add smbd_journald (1e68934)
   1#
   2#   smbd.py
   3#   
   4#   Get login statistics for a samba server.
   5#
   6#   NOTE: This file is now deprecated in favour of the newer journald mechanism
   7#   used in smbd-journald.py. This parser is still functional but is slower and
   8#   has less features. Please switch over if possible.
