Question

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在我的电脑上运行良好，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，但我得到了“连接超时。”在浏览器中。

我正在使用默认的apache配置。所以这就是我sites-available/default的样子：

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 NameVirtualHost *：80 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。所以我认为这不是防火墙问题。

我该怎么办？

因为连接已超时（未被拒绝），我猜这是防火墙问题检查您是否正在使用任何连接。

如果你的内核使用黑洞来关闭端口，它还有另一种可能性（它不会发送连接被拒绝 TCP数据包只是拒绝接听任何内容端口未使用）。但是你提到你的配置文件中有Listen 80，这意味着所有接口，所以你可能会遇到防火墙问题。

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HTTP连接到您的盒子：

sudo ufw allow proto tcp from any to 192.168.1.101 port 80

Apache：如何在192.168.1.102上看到192.168.1.101上的localhost？
