I changed the listener.ora file as follow
# listener.ora Network Configuration File:
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /usr/lib/oracle/xe/app/oracle/product/10.2.0/server)
      (PROGRAM = extproc)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 67.19...)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)Now getting this lsnr status
LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))
