实际错误是“无法读取控制连接的回复 – 超时”.
几分钟后,在传输了大量文件后,会发生此错误.

设置是：

FTP Client:  ncftpget running in Linux on VMWare Player 3.0
FTP Server:  somebody else's machine out on the Internet,configuration unknown
Guest OS:    Ubuntu 8.10 Linux 32-bit,with vmxnet and vmware tools installed.
Host OS:     Vista 64-bit
Network:     Linux VM connects to the Internet via Bridged NIC (also tried NAT)
FTP Mode:    PASV

我确实发现一些论坛帖子提到了某处2分钟的超时.但究竟在哪里以及如何解决它并不清楚.已尝试了一些故障排除步骤

>我已经从VMWare Player 3.0切换到VirtualBox 3.0.x,但没有运气.
>我也从NAT改为Bridged虚拟网卡,但没有运气

UPDATE
Linux VM上的Netstat和DIR-655路由器上的等效管理页面都显示连接处于活动状态(tcp’ESTABLISHED’状态). Vista根本看不到连接,如果仅在VM内管理连接状态,我认为这是正常的.

这是netsh界面tcp show global在Vista上的输出,以防它有用：

C:\Users\alex>netsh interface tcp show global
