*********************************************************************
Portions of the server's headers (Apache/2.4.38) are not in
the Nikto 2.1.6 database or are newer than the known string. Would you like
to submit this information (*no server specific data*) to CIRT.net
for a Nikto update (or you may email to sullo@cirt.net) (y/n)?
目录扫描没有什么收获，但是仔细查看页面：
y default, Debian does not allow access through the web browser to any file apart of those located in /var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.
The default Debian document root is /var/www/html/g@web. You can make your own virtual hosts under /var/www/mini@web. This is different to previous releases which provides better security out of the box.
有目录:g@web,访问该目录，可知为wordpress站点。
