我正在开发一个门户，该门户的主要目的是让我的所有同事（其计算机连接到同一网络）访问该门户。
我尝试重新安装我的 apache 服务器，但它仍然给我同样的错误。我使用的是Ubuntu 16.04
我对网络的了解有限，任何帮助都会非常有用。
这是当有人将服务器的 IP (192.168.60.250) 键入同一网络内的另一台电脑时的预期输出。
我安装了 virtualbox 并尝试测试问题，当我在虚拟框中打开 google chrome 和 firefox 时，我收到以下消息：
Firefox:
Unable to connect
Firefox can’t establish a connection to the server at 192.168.60.250.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Chrome:
This site can't be reached
192.168.60.250 is unreachable
ERR_ADDRESS_UNREACHABLE
I even tried to acess my portal using a machine that has windows as its os it it gives me this error:
Chrome on windows:
This site can't be reached
192.168.60.250 took too long to respond
ERR_CONNECTION_TIMED_OUT
编辑：我的虚拟机的 ifconfig：（由于我们办公室里的所有机器都是基于 Linux 的，所以我的虚拟机也使用 ubuntu）

这很奇怪。这个问题已经困扰我好几个星期了
我的快速猜测是端口 80 仅监听本地主机。但我不知道从哪里开始配置以及做什么。
我还可以从我的电脑 ping 到我们办公室的任何其他机器，反之亦然。我什至可以从我的电脑 ping 到我的虚拟机，反之亦然
I tried netstat -an | grep ':80'

而且我没有使用 XAMPP 或 WAMPP。我正在使用 LAMP 堆栈
我还访问了错误日志：

阿帕奇配置文件
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.
# Global configuration
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"
#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
Mutex file:${APACHE_LOCK_DIR} default
#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5
# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog ${APACHE_LOG_DIR}/error.log
#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#
LogLevel warn
# Include module configuration:
IncludeOptional mods-enabled/*.load
IncludeOptional mods-enabled/*.conf
# Include list of ports to listen on
Include ports.conf
# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.

# These deviate from the Common Log Format definitions in that they use %O
# (the actual bytes sent including headers) instead of %b (the size of the
# requested file), because the latter makes it impossible to detect partial
# requests.

# Note that the use of %{X-Forwarded-For}i instead of %h is not recommended.
# Use mod_remoteip instead.

只是为了添加更多信息。有时，由于某种未知的原因，我可以从另一台电脑或我的虚拟机访问我的本地网站。但是当我重新启动电脑时，错误又回来了
答案1
ACCEPT您在防火墙链（或其子级）中没有INPUT针对端口 80 上传入的流量的规则。有一个后备规则，REJECT该规则是受到攻击的规则。
如果您正在使用，ufw则需要添加规则以允许入站tcp/80流量。不幸的是，由于我不使用ufw自己（我是一个shorewall人），所以我无法为您提供精确的语法。 （我在一个评论你说它被禁用了。无论启用还是禁用，防火墙规则仍然存在，因此它们仍然有效。）
答案2
怎么样：
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
这仅用于测试目的，并不意味着在生产中，但如果在此之后可以访问网络服务器，那么这肯定是防火墙问题。
