DELL T640物理服务器安装Ubuntu16.04无法联网

#1

帖子 rhys03 » 2018-06-27 17:28

系统版本:Ubuntu16.06 LTS Desktop 64位
前提:MAC地址和IP绑定,关系对应才能上网
(1)服务器安装完系统后在图形化界面配置管理员分配下来的ip、网关、DNS,关闭防火墙;连接网线;结果连网关都ping不通
(2)修改个人笔记本的MAC、IP、网关、DNS;连接网线;结果可ping通网关,可正常上网
(2)把Ubuntu系统安装到U盘,在笔记本上从U盘启动,修改MAC、IP、网关、DNS;连接网线;结果也可ping通网关,可正常上网

部分配置信息如下,麻烦大神帮忙看看哪里有问题,感谢!!!
