Question

无法进入我的ftp服务器。我使用proftpd 1.3.4a和mod_tls / 2.4.3。

我怀疑是 TLSOptions 指令

的错误

TLSEngine                        on
TLSLog                           /var/log/proftpd/tls.log
TLSProtocol                      SSLv23
TLSRSACertificateFile            /etc/proftpd/ssl/proftpd.cert.pem
TLSRSACertificateKeyFile         /etc/proftpd/ssl/proftpd.key.pem
TLSOptions                       NoCertRequest EnableDiags NoSessionReuseRequired
TLSVerifyClient                  off
TLSRequired                      on

tls.log 在我尝试连接时说了这个

有什么想法吗？

Answer 1

TLSRequired                      on
....
SSL/TLS required but absent for authentication, denying USER command

我怀疑您没有使用SSL / TLS连接到服务器。但是，只有在通过SSL / TLS完成时才允许进行身份验证。检查ftp客户端中您实际使用SSL / TLS的设置。
