ftp 问题(netbsd和openbsd）？

[wkx9dragon]

自从昨天更新了netbsd和openbsd后，突然不能ftp了。是不是不能匿名登录了，不知道用户名，应该是那个。

$ ftp ftp.netbsd.org
Trying 204.152.190.15...

$ uname -a

问题解决了，但为什么会这样？要电邮件，感觉象中木马了。

刚才，又试了一遍，密码可以随便输入哦，呵呵。

既然是匿名ftp,你可以直接使用 -a参数，这样就没必要输入用户名：anonymous和任意密码了。

代码: 全选

谢谢了，没有细看man ftp，以前没有这个问题，所以没注意。长见识了。
