Debian 無法解析主機名

我在解析在 VMWare 上執行的 Debian 上的主機名時遇到問題。

它只是突然停止工作。在解除安裝 percona 伺服器並刪除 /etc/mysql. 最初它認為這是一個網路問題，當主機在來賓執行時進入睡眠狀態，這是 VMWare 的一個已知問題。但它不可能。

Debian 7.4，已安裝 VMWare 工具

/etc/resolv.conf

ping、dig 和 nslookup 輸出

任何想法如何解決這個問題？

/etc/nsswitch.conf

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         compat
group:          compat
shadow:         compat

hosts:          files mdns4_minimal wins [NOTFOUND=return] dns mdns4
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis

使用您目前的 dns ，只有在請求失敗nsswitch.conf時才會請求。以下是我係統上手冊頁wins的相關摘錄：nsswitch.conf

notfound

查找成功，但未找到請求的條目。此條件的預設操作是“繼續”。

return

現在返回一個結果。不要呼叫任何進一步的查找函式。

在您的範例中，您成功查詢了 WINS，但沒有檢索到google.com. 要解決此問題，您可以刪除[NOTFOUND=return]或重新排序為主機查找而查詢的服務。這是一個範例修復：

hosts:          files mdns4_minimal dns wins [NOTFOUND=return] mdns4
