SUSE_Linux zypper安装失败

Question

我正在使用SUSE linux服务器，我尝试了zypper命令，如下所示..

zypper install [argument]

但结果消息加速了

Retrieving repository 'sles112repo' metadata [\]
Download (curl) error for 'http://mirror.asterdata.com/sles/11.2/x86_64/repodata/repomd.xml':
Error code: Connection failed
Error message: Couldn't resolve host 'mirror.asterdata.com'

Abort, retry, ignore? [a/r/i/?] (a):     http://mirror.asterdata.com/sles/11.2/x86_64/repodata/repomd.xml
Invalid answer 

我试图通过命令

访问上面的URL

curl "http://mirror.asterdata.com/sles/11.2/x86_64/repodata/repomd.xml"

然后消息出来

curl: (6) Couldn't resolve host 'mirror.asterdata.com'

我想我需要修复该网址设置 我怎样才能解决这个问题？
