请教一个使用ftp ssl/tls的问题 谢谢

linuxsmth

我在客户端上使用
./configure CC=gcc CFLAGS='-O3' --prefix=/home/kkk/lftp --without-gnutls --with-openssl安装支持ssl/tls协议的lftp

服务器上使用
./configure CC=gcc CFLAGS='-O3' --prefix=/home/kkk/proftpd --enable-autoshadow --enable-ctrls --with-modules=mod_tls安装proftpd

并且proftpd.conf中有关tls/ssl的配置如下：

<IfModule mod_tls.c>
    TLSEngine on
    TLSLog /var/log/proftpd-tls.log
    TLSProtocol TLSv1
    #TLSProtocol SSLv23

    # Are clients required to use FTP over TLS when talking to this server?
    TLSRequired off

    # Server's certificate
    TLSRSACertificateFile /etc/tls/private/server.cert.pem
    TLSRSACertificateKeyFile /etc/tls/private/server.key.pem

    # CA the server trusts
    #TLSCACertificateFile /etc/pki/tls/proftpd/root.cert.pem

    # Authenticate clients that want to use FTP over TLS?
    TLSVerifyClient off

    # Allow SSL/TLS renegotiations when the client requests them, but
    # do not force the renegotations.  Some clients do not support
    # SSL/TLS renegotiations; when mod_tls forces a renegotiation, these
    # clients will close the data connection, or there will be a timeout
    # on an idle data connection.
    TLSRenegotiate required off

</IfModule>


现在使用lftp想访问proftpd  随便运行一个ls命令 提示出错：

<--- 220 ProFTPD 1.3.1 Server (ProFTPD)
---> FEAT
<--- 211-Features:
MDTM
AUTH TLS
PBSZ
PROT
REST STREAM
SIZE
<--- 211 End                  
---> AUTH TLS
<--- 234 AUTH TLS successful
---> USER ftp
**** SSL_connect: unknown protocol
---- Closing control socket
ls: Fatal error: SSL_connect: unknown protocol

服务器端proftpd日志如下
May 15 21:42:36 mod_tls/2.1.2[25070]: using default OpenSSL verification locations (see $SSL_CERT_DIR environment variable)
May 15 21:42:36 mod_tls/2.1.2[25070]: TLS/TLS-C requested, starting TLS handshake
May 15 21:42:36 mod_tls/2.1.2[25070]: unable to accept TLS connection:
  (1) error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
May 15 21:42:36 mod_tls/2.1.2[25070]: TLS/TLS-C negotiation failed on control channel

请问这是什么原因呢 怎么解决 谢谢
