sudo:无法解析主机ServerName(需要很长时间才能"sudo su")

Question

我使用vmware并安装ubuntu 12.10作为我的客户操作系统.并运行我的电脑,我的网络接口是无线卡,但每当我尝试sudo时,我应该等待很长时间.和回声

sudo: unable to resolve host ServerName pocUbuntu
[sudo] password for poc: 

我通过谷歌搜索几乎解决方案,没有解决方案可以解决我的问题.

当我输入主机名

root@ServerName pocUbuntu:/home/poc# hostname
ServerName pocUbuntu

还有我的主机文件

 cat /etc/hosts
127.0.0.1   localhost pocUbuntu
127.0.0.1   pocUbuntu
127.0.1.1   pocUbuntu

# 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

我可以在ping服务器名pocUbuntu时得到确认

root@ServerName pocUbuntu:/home/poc# ping pocUbuntu
PING localhost (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_req=1 ttl=64 time=0.030 ms
64 bytes from localhost (127.0.0.1): icmp_req=2 ttl=64 time=0.026 ms

我应该怎么做 ？解决烦人的问题.
