说明

匿名用户登录到vsftpd后所拥有的权限即系统用户ftp的权限.

Windows下中文目录支持

现在把vsftpd代码里的feat命令和对opts命令返回信息做一下修改.

把features.c文件中的

vsf_cmdio_write_raw(p_sess, " UTF8\r\n");

去掉

把opts.c文件的handle_opts函数修改成如下:

void
handle_opts(struct vsf_session* p_sess)
{
  str_upper(&p_sess->ftp_arg_str);
  //if (str_equal_text(&p_sess->ftp_arg_str, "UTF8 ON"))
  //{
  //  vsf_cmdio_write(p_sess, FTP_OPTSOK, "Always in UTF8 mode.");
  //}
  //else
  //{
    vsf_cmdio_write(p_sess, FTP_BADOPTS, "Option not understood.");
  //}
}
