dos下登录fedora下的vsftp失败

我有两个FTP站点:A - windows xp下的IIS, B - 虚拟机fedora12下的vsftp,都是正常运行的,同时这两个站点都允许匿名访问。

dos下访问A,或在fedora12终端下登录B,都是成功的。但是在dos下访问B,或在fedora12终端下访问A都是失败的。为什么呢?

 

想来想去不明白,因为我的windows xp已经关闭了防火墙,而且fedora也已经关闭了selinux。搞到最后原来是fedora12下的防火墙的缘故。

最后,把fedora下的防火墙也关了,命令如下:

[root@vsftpd #70]#service iptables stop
iptables
:清除防火墙规则:                                 [确定]
iptables
:将链设置为政策 ACCEPTfilter                    [确定]
iptables
:正在卸载模块:                                   [确定]

这样之后,就可以成功地登录windows下的ftp-A了,同时,dos也可以成功地登录fedora12下的B了。看看结果吧:

dos登录A

原来linux下的防火墙的服务名是:iptables,现在才知道,慢慢积累吧!
