编辑1：

问题似乎与MySQL组件有关.因为如果我从配置文件中删除每个SQL指令,它确实可以在ftp / ftpes,sftp和ftps上运行

编辑2：

如果我把一个现有主机没有托管数据库,连接到ftp守护程序将挂起并最终超时,而如果我放错了数据库或非响应主机,它将尝试运行unix auth instaed of mysql auth.

原始问题

我有一个proftpd配置文件,在proftpd 1.3.4b和proftpd 1.3.4d上进行了测试.现在我想在新系统上编译AIX 6.1.
我正在使用IBM XLc编译器.

这是我安装的库：

    libmpc-devel-1.0.1-2
    gcc-cpp-4.6.1-1
    zlib-devel-1.2.7-2

这是我用来编译的脚本：

export CONFIG_SHELL=/opt/freeware/bin/bash
export CONFIG_ENV_ARGS=/opt/freeware/bin/bash
export CC=cc
export CFLAGS="-qmaxmem=16384 -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_AIX52 -D_AIX53 -D_AIX61 -D_ALL_SOURCE -DFUNCPROTO=15 -O -I/opt/freeware/include"
export CXX=xlC
export CXXFLAGS=$CFLAGS
export CPPFLAGS='-U__STR__'
export F77=xlf

export LD=ld
export LDFLAGS="-L/opt/freeware/lib -Wl,-blibpath:/opt/freeware/lib:/usr/lib:/lib:/opt/freeware/lib/mysql:/opt/freeware/lib/mysql/mysql"

make clean
./configure  '--with-modules=mod_tls:mod_sql:mod_sql_mysql:mod_sql_passwd:mod_sftp:mod_sftp_sql' '--without-getopt' '--enable-openssl' '--with-includes=/home/poney/libmath_header:/home/poney/include_mysql/mysql/' '--with-libraries=/home/poney/libmath_lib:/opt/freeware/lib/mysql/mysql:/opt/freeware/lib/mysql/mysql/libmysqlclient.a' '--prefix=/usr/local/proftpd'
make

事情是它编译没有进一步警告. make install时我还会收到警告：

ld: 0711-224 WARNING: Duplicate symbol: .bcopy
ld: 0711-224 WARNING: Duplicate symbol: .memmove
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

我的配置允许FTPS SFTP和FTP,如果我尝试连接ftps,它确实有效,直到我输入密码：

openssl s_client -connect 127.0.0.1:210 -starttls ftp

之后什么都没有,它什么都不做.在proftpd方面,deamon确实提供了一些跟踪：
see pastbin

我在这里看不到任何有用的东西.

我很确定这个库有什么问题,但我真的不知道为什么它不想在最后因为编译而没有问题.

解决方法:

最后答案是：
这不是一个错误,这是一个功能

如果您尝试连接dns中已知的数据库但数据包被防火墙丢弃,那么您将陷入客户端的sql超时(大约85秒),如果您已将modthqlc设置为AUthOrder,则无法进行其他身份验证第一.

所以我的编译选项也正确,包版本也是正确的.
