当我尝试使用地址\\REPO (REPO 的 NETBIOS 名称)连接到我的CentOS 6.2 x86_64服务器的 samba 共享时,它超时并显示错误;如果我直接通过 IP 这样做,它工作正常。此外,尽管我的 samba 设置正确,但我的服务器无法作为 WINS 服务器正常工作(详情请参见下文)。
如果我停止 iptables 服务,一切正常。
我使用此页面作为使用哪些端口的参考:http: //www.samba.org/samba/docs/server_security.html
具体来说:
UDP/137 - used by nmbd
UDP/138 - used by nmbd
TCP/139 - used by smbd
TCP/445 - used by smbd
我真的真的真的很想保留下面的安全 iptables 设计,但只是解决这个特定问题。
