The ftp command accepts the server name, not a URL. Your session likely should look like:
ftp 命令接受服务器名称，而不是 URL。您的会话可能应如下所示：
ftp ftp-trace.ncbi.nih.gov
(Server asks for login and password)
cd /1000genomes/ftp/data/
mget *

It looks to me like the computer that isn't working is already adding the ftp:to the URL, have you tried removing it from yours and seeing if that works?
它看起来对我这样没有工作已添加计算机ftp:的URL，你尝试从你删除它，看是否可行？

This depends on the ftp client you are using. On Mac OSX (ftp client from BSD), for example, the default command line ftp client accepts the full url, while for example in CentOS the default client doesn't, and you need to connect just to the hostname. So, it depends on the flavor of linux and the installed default ftp client.
这取决于您使用的 ftp 客户端。例如，在 Mac OSX（来自 BSD 的 ftp 客户端）上，默认命令行 ftp 客户端接受完整 url，而例如在 CentOS 中，默认客户端不接受，您只需要连接到主机名。因此，这取决于 linux 的风格和安装的默认 ftp 客户端。
Default ftp client in CentOS (ARPANET):
CentOS (ARPANET) 中的默认 ftp 客户端：
ftp ftp-trace.ncbi.nih.gov
cd 1000genomes/ftp/data
If you want to use the full url in CentOS 5.9 or Fedora 18 (where I tested it), you could install an additional ftp client. For example ncftp and lftp have the behavior you are looking for.
如果您想在 CentOS 5.9 或 Fedora 18（我在其中测试过）中使用完整 url，您可以安装额外的 ftp 客户端。例如 ncftp 和 lftp 具有您正在寻找的行为。

Another, more efficient, way to retrieve a page, is using wget or curl. These work for http, ftp and other protocols.
