通过 SFTP 和 FTP 进行 ProFTPd 配置

我有一个 ProFTPd，它实际上使用 FTP 协议，但我也想使用 SFTP。
我找到了一个带有 block 的解决方案<VirtualHost>，但它对我来说不起作用。

  <IfModule mod_sftp.c>
      <VirtualHost 0.0.0.0>

        TLSEngine          off
        SFTPEngine         on
        Port               2222
        SFTPLog            /var/log/proftpd/sftp.log
        Include            /etc/proftpd/sql.conf

        SFTPHostKey        /etc/ssh/ssh_host_rsa_key
        SFTPHostKey        /etc/ssh/ssh_host_ecdsa_key

        SFTPCompression    delayed
        DefaultRoot        ~
        RequireValidShell  on

     </VirtualHost>
  </IfModule>


这是 `/var/log/proftpd/sftp.log` 的输出

正确。要让您的 FTP 守护程序在 FTP/21 和 SFTP/2222 上都能正常工作，解决方案是在 <IfModule mod_sftp.c> 内包含 <VirtualHost 0.0.0.0> 部分。

我正在 /etc/proftpd/proftpd.conf 中共享我的配置文件的这一部分，它运行良好。

<VirtualHost 0.0.0.0>
  
    SFTPEngine on
    Port 2222
    SFTPAuthMethods password
    RequireValidShell      off
    SFTPLog /var/log/proftpd/sftp.log
    Include /etc/proftpd/sql.conf

    SFTPHostKey /etc/ssh/ssh_host_rsa_key
    SFTPHostKey /etc/ssh/ssh_host_dsa_key
    
    SFTPCompression delayed
    DefaultRoot
</VirtualHost>
