AIX 5.3 FTP问题排错
问题：
远程AIX 5.3，本地Windows XP，需要传输文件到AIX上
目前具备root权限，telnet功能。
在CMD下FTP问题：
C:\Documents and Settings\dota>ftp 192.168.1.66
> ftp: connect :未知错误号
ftp> quit
有未知错误号，怀疑AIX上的FTP服务没有启动
在AIX上：
# vi /etc/inetd.conf
#ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd
#telnet stream tcp6 nowait root /usr/sbin/telnetd telnetd -a
#shell stream tcp6 nowait root /usr/sbin/rshd rshd
#kshell stream tcp nowait root /usr/sbin/krshd krshd
#login stream tcp6 nowait root /usr/sbin/rlogind rlogind
#klogin stream tcp nowait root /usr/sbin/krlogind krlogind
去掉FTP服务的#号
Wq保存退出
# refresh -s inetd
0513-095 The request for subsystem refresh was completed successfully.
回到CMD上尝试，问题依旧。
没有报具体的错误号，怀疑和防火墙有关，现状是windows防火墙服务停止了，但是防火墙的驱动级别的内核依然似乎有作用，于是启用防火墙，再试，允许此访问
C:\Documents and Settings\dota>ftp 192.168.1.66

报530错误，继续查用户
怀疑是FTP用户问题
# more /etc/ftpusers
root
#
# vi /etc/ftpusers
root
原来将root拒绝了，去掉，wq保存退出
CMD再试
