Question

我有一个用于运行容器的Ubuntu服务器（Ubuntu 19.10）。我正在尝试使用其主机名访问（即ping）服务器。我可以使用IP到达它。我花了一段时间，但我发现我需要安装winbind和libnss-winbind才能解析Ubuntu服务器。我根据在网上和man中找到的指南配置了所有内容，但仍然无法在Windows机器上解析Ubuntu Server的主机名。从Ubuntu解析Windows机器主机名也是如此。

andy@cship:~$ sudo apt list winbind libnss-winbind
Listing... Done
libnss-winbind/eoan-updates,eoan-security,now 2:4.10.7+dfsg-0ubuntu2.4 amd64 [installed]
winbind/eoan-updates,eoan-security,now 2:4.10.7+dfsg-0ubuntu2.4 amd64 [installed]

我根据手册页配置了主机文件。

andy@cship:~$ cat /etc/hosts
# The following lines are desirable for IPv4 capable hosts
127.0.0.1       localhost

# 127.0.1.1 is often used for the FQDN of the machine
127.0.1.1       cship.local cship

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

/ etc / hostname设置为cship

andy@cship:~$ cat /etc/hostname
cship

主机名正确返回cship作为主机名

andy@cship:~$ hostname
cship

我可以使用主机名cship来ping通自己（即在同一台计算机上本地）

andy@cship:~$ ping cship
PING cship.local (127.0.1.1) 56(84) bytes of data.
64 bytes from cship.local (127.0.1.1): icmp_seq=1 ttl=64 time=0.105 ms
^C
--- cship.local ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.105/0.105/0.105/0.000 ms

我已经安装了winbind和libnss-winbind，winbind正在运行

andy@cship:~$ sudo systemctl status winbind

我为/etc/nsswitch.conv添加了胜利

andy@cship:~$ grep wins /etc/nsswitch.conf
hosts:          files wins dns

将wins添加到`/etc/nsswitch.conv后，尝试解析本地网络中另一台机器的主机名时失败。

andy@cship:~$ ping google.com
PING google.com (172.217.168.14) 56(84) bytes of data.

andy@cship:~$ ping destop-abcd
ping: destop-abcd: Temporary failure in name resolution

而且我仍然无法从其他Windows主机ping计算机。

winbind / wins：名称解析暂时失败/无法按主机名ping
