Oracle 绑定后无法通过指定 IP 访问，求教

如题，有一台 linux 机器上要装 oracle，折腾半天了。

现在服务已经安装成功，并且正常启动。

使用如下命令启动成功：

sudo lsnrctl start
sqlplus /nolog
conn / as sysdba
startup

并且在这种访问模式下能够成功获取到数据

SQL> select * from scott.dept;

    DEPTNO DNAME	  LOC
---------- -------------- -------------
	10 ACCOUNTING	  NEW YORK
	20 RESEARCH	  DALLAS
	30 SALES	  CHICAGO
	40 OPERATIONS	  BOSTON

于是把服务绑定到局域网 IP，想要从另一台机器上登录，修改了 listener.ora

# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/rogear/tools/oracle11g

和 tnsnames.ora

# tnsnames.ora Network Configuration File: /home/rogear/tools/oracle11g/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

然后重启数据库和监听程序。

这时候使用登录命令会得到提示：

sqlplus scott/[email protected]:1521/orcl

ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor

请问可能是什么原因造成的？ 当前可以确保网络是连同的，确实能访问到 192.168.1.100:1521 上的程序，但是登录失败，怎么回事呢
