proftp真的很爱出问题!最典型的421错误!
proftp真的很爱出问题!最典型的421错误!我新架一台proftp服务器,系统是bsd6.2 通过ports安装,make config选择好sql 已经限额模块
现在装好了,版本是
sk# pkg_info |grep proftp
proftpd-1.3.1.r2_3Highly configurable ftp daemon
sk#
现在我将另外一台服务器的proftpd.conf 粘贴过来
# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.It establishes a single server
# and a single anonymous login.It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.
#ServerName "ProFTPD Default Installation"
ServerName "sk's ftp"
ServerType standalone
DefaultServer on
# Port 21 is the standard FTP port.
Port 21
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask 022
# To prevent DoS attacks, set the maximum number of child processes
# to 30.If you need to allow more than 30 concurrent connections
# at once, simply increase this value.Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).

数据库也是另外一台生产服务器的结构,现在也将vipw中的ftpuser 和group 的数据添加到了新服务器.然后
#echo "proftpd_enable="yes" > /etc/rc.conf"
#sh /etc/rc
现在#netstat -an|grep 21可以看到ftp已经启动了,但是:
sk# ftp 127.0.0.1
Connected to 127.0.0.1.
421 Service not available, remote server has closed connection.
ftp>
ipfw list
65535 allow ip from any to any
不知道这是啥原因,根据个人经验觉得是mysql没有连接上,但是我用proftp 的用户又能登陆!分析了里面的数据结构也是对的.真的找不到原因了!希望有高手帮忙!

[ 本帖最后由 zhengwei_zw 于 2007-4-24 17:23 编辑 ] 我也遇到同样问题，正在尝试换mysql 4.1系列的数据库试试，估计是高版本数据库不太兼容 我是MYSQL5，将配置文件的连接数据库的用户名使用root的，就可以正常登陆了！
