请教一下oracle的启动监听问题，谢谢！！

首先是listener。ora的内容
lISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS = (PROTOCOL = TCP)(HOST = 100.100.100.100)(PORT = 1521))
)
)


SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oradata/product/9.2.0.4)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ora9204)
(ORACLE_HOME = /oradata/product/9.2.0.4)
(SID_NAME = oracle)
)
)

然后是tnsnames。ora的配置单
SMSRemote =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 100.100.100.100)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora9204)
)
)
INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = charvi)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = MODOSE)
(PRESENTATION = http://HRService)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

运行lsnrctl start 后：

问题就出来了：”The listener supports no services“
我要启动监听的目的是因为我在sqlnet.ora中写了限制了特定的IP才可以访问oracle的语句，需要重启监听，但启动不了，也限制不了IP，望大家指点迷津啊～～谢谢
