刚搭建的环境，服务端是windows 2008 R2+TSM 6.3,IP地址为：10.10.1.40
客户端是redhat 6.4，IP地址为：10.10.1.45
配置完Lanfree后进行备份测试
在客户端先进行备份一些文件，有报错如下：
[root@oracle bin]# dsmc se -subdir=yes "/tmp/*"
IBM Tivoli Storage Manager
Command Line Backup-Archive Client Interface
Client Version 6, Release 3, Level 0.0
Client date/time: 08/13/2015 16:05:22
(c) Copyright by IBM Corporation and other(s) 1990, 2011. All Rights Reserved.
Node Name: ORACLE
ANS9201W LAN-free path failed.
Node Name: ORACLE
这个报错之后也能开始备份，不过，备份通道是TCP/IP网络
Session established with server BACKUP: Windows
Server Version 6, Release 3, Level 0.0
Server date/time: 08/13/2015 16:05:22 Last access: 08/13/2015 15:47:21
Selective Backup function invoked.
然后我在客户端的dsmerror.log发现如下报错：
08/13/2015 16:05:22 ANS5216E Could not establish a TCP/IP connection with addres
s '10.10.1.45:1500'. The TCP/IP error is 'Connection refused' (errno = 111).
08/13/2015 16:05:22 ANS9201W LAN-free path failed.
08/13/2015 16:05:22 ANS9201W LAN-free path failed.
提示拒绝连接，我到TSM服务端用netstat -an 查看1500端口是listening状态
以下是TSM客户端的配置文件：
SErvername BACKUP

现在出现这个问题，不知道原因怎么排查，请各位帮忙指导一下
