安装手册上4-3-2来做，确定防火墙，杀毒软件已关，网络连接，硬件网线连接没问题，重新启动出现一下信息

对了。开发板是192.168.1.20   ubuntu 上是192.168.1.128

luy3728000

nfs-kernel-server 这个已经安装， restart 时显示

但是 ，我输入 service nfs status
提示，nfs: unrecognized service “不可识别到服务”？请问这么会这样？

飞凌-alexlee

你能ping通虚拟机吗？

luy3728000

回复 6# 飞凌-alexlee
我在u-boot命令提示符下

提示

在虚拟机上ping开发板也ping不同通

luy3728000

回复 6# 飞凌-alexlee
怎么是CS8900 不是DM9000的吗？

飞凌-alexlee

不能再uboot下使用ping

你用你pc的windows，ping linux~~

luy3728000

也平ping不通阿

luy3728000

我把虚拟机换成 从 NAT 换到 host0-only方式时，可以从XP ping通虚拟机的ubuntu ,但是挂载时还是出现

纠结啊！！搞了两三天这个了

飞凌-alexlee

你选择桥接模式~~

luy3728000

桥接模式也试过，几种方式都试过了，问题还是一样啊。

飞凌-alexlee

你重新下载最新的内核跟uboot

飞凌-fatfish

如果楼上有什么问题，最好是开贴详述
