To start with prelude-lml, you have to create a starting profile, e.g. "prelude-lml" by running on the manager side: # prelude-adduser registration-server prelude-manager \ --uid=564 --gid=564 and on the sensor side: # prelude-adduser register prelude-lml "idmef:w" \ --uid 564 --gid 564 To start prelude-lml at boot-time, you could use: if [ -x ${LOCALBASE}/bin/prelude-lml ]; then echo -n ' prelude-lml'; ${LOCALBASE}/bin/prelude-lml -d fi
