linux-ping,ssh等使用的IP地址与nslookup,主机,
作者：互联网
新安装Ubuntu15.10后,我的命令(ping,ssh,…)使用的IP地址与nslookup,host,dig,…解析的IP地址不同.
怎么会这样
user@ubuntu-15-10:~$nslookup foobar.com
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
foobar.com canonical name = foobar.homeip.net.
Name: foobar.homeip.net
Address: 12.34.56.78
user@ubuntu-15-10:~$host foobar.com
foobar.com is an alias for foobar.homeip.net.
foobar.homeip.net has address 12.34.56.78
user@ubuntu-15-10:~$ping foobar.com
PING foobar.com (192.168.1.3) 56(84) bytes of data.

我的/etc/resolv.conf

search localdomain.home
我的/etc/nsswitch.conf
# /etc/nsswitch.conf

# `info libc "Name Service Switch"' for information about this file.
passwd: compat
group: compat
shadow: compat
hosts: files mdns4_minimal [NOTFOUND=return] wins dns
networks: files

services: db files
ethers: db files
rpc: db files
netgroup: nis
在/ etc / hosts中没有foobar.com的条目
有人知道吗？
解决方法:
经过一番调查,我发现了一个修复方法.
问题出在/etc/nsswitch.conf中：
在“主机”行：“ dns”条目应在“ wins”条目之前…
我不明白背后的原因,但是现在它的工作方式与预期的一样
