我在Ubuntu上运行Apache。我的IP地址是192.168.1.101
虽然http://localhost和http://192.168.1.101在我的PC中运行良好，但我无法使用http://192.168.1.102从笔记本电脑中访问它
很奇怪。我可以ping 192.168.1.101，但我在浏览器中看到“连接已超时”。
我使用的是默认的apache配置，所以我的sites-available/default如下所示：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /home/www/public_html
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /home/www/public_html>
Options Indexes FollowSymLinks MultiViews
#AllowOverride None
AllowOverride all
Order allow,deny
allow from all
</Directory>/etc/apache2/posrts.conf名称虚拟主机 *：80侦听80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>我的笔记本电脑也运行Ubuntu。所以我不认为这是防火墙的问题。

因为连接超时（不是拒绝），我猜这是一个防火墙问题检查，如果你正在使用任何。
如果你的内核对关闭的端口使用了 * 黑洞 *（它不会发送 * 连接被拒绝 * 的TCP包，只是在端口未被使用时拒绝回答任何问题），还有一种可能性。但是你提到你的配置文件中有
Listen 80，这意味着所有接口，所以你很有可能遇到了防火墙问题。在UFW（Ubuntu中的默认防火墙）中，您可以添加防火墙规则以允许传入的HTTP连接到您的设备：
