我遇到了远程命令行无法解析本地主机名的问题。它不显示为 user@localhostuser@ip 或任何变体,而是显示为 user@(none):

Using username "rogue".
rogue@<my-ip>'s password:
Linux (none) 3.13.7-x86_64-linode38 #1 SMP Tue Mar 25 12:59:48 EDT 2014 x86_64

rogue@(none):~$

任何正在进行的命令都会导致此警告消息:

rogue@(none):~$ sudo service nginx start
sudo: unable to resolve host (none)
[sudo] password for rogue:

查看我的主机和主机名文件,我没有发现任何异常:

/etc/主机名

127.0.0.1 localhost
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

/etc/主机

127.0.0.1       localhost
127.0.1.1 debian

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

我的网络配置可能有什么问题?如果可能的话,我希望它显示 user@my.domain,但我需要 localhost 仍然正确路由到 127.0.0.1
