Ping 可以工作，但 nslookup 没有看到 resolv.conf 域搜索

我的/etc/resolv.conf包含一行search如下的内容：

search a.local b.local c.local

该ping命令运行正常：

$ ping some-server
PING some-server.b.local (10.20.30.40) 56(84) bytes of data.
64 bytes from 10.20.30.40 (10.20.30.40): icmp_seq=1 ttl=58 time=47.8 ms

但是，如果没有 FQDN，则以下nslookup(或host) 命令不起作用：

$ nslookup some-server
;; Got SERVFAIL reply from 10.100.0.200, trying next server
;; Got SERVFAIL reply from 10.100.0.201, trying next server
Server:     127.0.0.53
Address:    127.0.0.53#53

** server can't find some-server: SERVFAIL

$ nslookup some-server.b.local
Server:     10.100.0.200
Address:    10.100.0.200#53

Non-authoritative answer:
Name:   some-server.b.local
Address: 10.20.30.40

我该如何修复 nslookup 以便能够正确地与我的搜索域配合使用？

要确保您具有正确的 DNS 设置，请尝试执行以下操作：

  sudo nano /etc/resolvconf/resolv.conf.d/base

然后粘贴以下内容：

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 8.8.8.8
nameserver 8.8.4.4

然后退出并保存文件

  sudo resolvconf -u   #updates the resolve file from the file we made above. 
  cat /etc/resolv.conf # prints the contents of the resolv file

它应该会显示我们保存在那里的文本。之后尝试之前失败的 nslookup，希望它现在能正常工作。
