xmanager訪問centos 6.4的問題

seacnboy

使用xmanager5訪問centos 6.4，centos 6.4的177端口已打開，本地防火墻已關(guān)閉。
[root@ebs-38100 ~]# netstat -anp | grep 177
udp        0      0 0.0.0.0:177                 0.0.0.0:*                               27729/gdm-binary   

從xmanager界面可以看出已經(jīng)解析出centos 6.4的主機名，但是訪問仍然失敗，xmanager日志為：
Xdmcp Connection Address 0: 192.168.2.103
Xdmcp Connection Address 1: fe80::9524:77b6:bfe1:b1ae
