Ubuntu
在除一台客戶端外的所有機器上通過 SSH 和 HTTP 訪問伺服器
編輯3：
奇怪的發現。這個問題只發生在一個特定的客戶身上。除了我的主桌面之外，任何電腦都可以通過域名訪問所有三個站點。此桌面只能通過本地 IP 地址 192.168.0.X 訪問伺服器（用於 HTTP 或 SSH），不能通過外部 IP 或域名訪問。在所有其他機器上，一切都按預期工作。
我檢查了我的 fail2ban 日誌和防火牆，以確保這台特定的機器沒有被阻止。還有什麼問題？無法從我的主桌面訪問我的伺服器是一個巨大的痛苦。
兩者都通過乙太網電纜硬連線到同一個路由器，如果這很重要的話。

我在 Apache 中定義了三個虛擬主機（所有三個都儲存了 .conf 文件
/etc/apache2/sites-available，已通過 啟用a2ensite）。在從 Ubuntu 16.04 更新到 Ubuntu 18.04 之前，這三個都執行良好。更新後，它們都不會載入到瀏覽器中，所以我做了很多故障排除。這是我到目前為止所做/仔細檢查的內容：
- 重新安裝 apache2 和 php
- 已檢查
apache2.conf，包括執行apache2ctl -t調試 - 沒有錯誤。- 檢查每個站點的 conf 文件，執行
apache2ctl -S以確保所有站點都被辨識。每一個都指定ServerName（域名）和DocumentRoot（本地目錄）。這些值已經過三次正確性檢查。- 已檢查 DNS 設置。所有三個域名都指向正確的 IP 地址（用於
dig確認）。- 檢查防火牆設置 - 埠 80 已打開並且 Apache 正在偵聽它。
通過域名訪問三個站點中的任何一個時，瀏覽器都會給出錯誤消息：“無法訪問此站點。domain.com 響應時間過長。”
如果我在瀏覽器中輸入 IP 地址而不是域名，我可以毫無問題地訪問預設站點（Apache 載入的第一個站點）。
我覺得這是某種 Apache 配置，我以某種方式搞砸了，但我所擁有的只是
apache2.conf全新安裝的預設文件以及虛擬主機 conf 文件，它們都具有以下格式：<VirtualHost *:80> ServerName somedomain.com DocumentRoot "/var/www/foldername" <Directory /var/www/foldername> Options -Indexes AllowOverride XXXXXXXXXX </Directory> </VirtualHost>AllowOverride
None用於一個站點和Fileinfo Options另外兩個站點。知道我錯過了什麼嗎？

我不確定這是否是“正確”的解決方案，但它對我有用。最後，我所做的只是在
/etc/hosts無法連接到伺服器的“損壞”客戶端上添加一行。我放置了內部 IP 地址（我將路由器設置為對所有主要設備（包括我的伺服器）保持相同），然後是該伺服器上託管的域的空格分隔列表。例子：192.168.0.1 domain1.com domain2.com domain3.com sub.domain3.com這似乎不是一個好的、動態的、永久的修復。但它現在解決了這個問題。
