所以我在我的Ubuntu 10.10服务器上安装了ProFTP。 使用FileZilla，我可以连接和身份validation，但我不能得到目录列表。 以下是返回给我的最后几行：
Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/home/todolist" is the current directory Command: TYPE I Response: 200 Type set to I Command: PASV Error: Disconnected from server: ECONNABORTED - Connection aborted Error: Failed to retrieve directory listing 我没有改变任何configuration，所以我应该改变/设置，以便我可以正确使用FTP？

了解主动与被动FTP： 链接 。
您可能忘记打开/转发防火墙上的被动端口，或者您没有在您的configuration中启用它们。
在您的configuration中取消注释此行：
# PassivePorts 49152 65534
进行中：
PassivePorts 49152 65534
然后在防火墙中打开这些端口： 21和范围49152-65534 。
确保您在此之后重新启动ProFTP服务。
当通过Windows FileZilla和linux konqueror通过ftp.myserver.com连接到我的服务器时，出现以下错误：
Error: Disconnected from server: ECONNABORTED - Connection aborted Error: Failed to retrieve directory listing
这是我所做的，导致了这个问题
我发现我的NETGEAR无线中继器是怪罪。 它被其他人重置为出厂默认设置，从而打破了以前让Filezilla和ftp做的事情的特殊设置。 Netgear无线中继器被用作多台计算机的路由器，并阻止了Filezilla使用的一些命令，但不是全部。 这种现象造成了奇怪的行为，我的连接将部分工作几分钟，然后会崩溃，并提供上述错误。
总结 Netgear路由器是蹩脚的，一个关机可以意外地导致他们重置他们到最高的安全级别。
解决scheme通过使用互联网的备用连接（备用路由），在mc-donalds或朋友家或邻居的wifi上使用连接，来诊断隔离哪个中继器/路由器可能被设置为太高的安全级别。 （我在我的android手机上使用tethering）。 当我这样做，我的连接到我的服务器工作正常，我可以回溯和使用淘汰找出哪个设备是问题。 解决的办法是进入我的networking无线中继器，并将限制设置更安全的水平，一切工作。
其他可能的原因可能会发生
另外，我在我的Windows机器上运行“ZoneAlarm”软件，这是拒绝filezilla。 如果您有任何第三方安全软件，您可能需要暂时closures它，以查看是否阻止了您。
由于硬件故障或无线干扰，您的路由器可能会遭受零星的错误。 当无线路由器变老时，有时会随机丢弃连接，login到192.168.1.1检查出来。
FTP需要打开443端口。 尝试启用防火墙上的端口443到服务器。 login到192.168.1.1，你的路由器，并查看“端口范围转发”TCP和UDP为您的IP地址。 看看是否有帮助。
