nfs n了一天还是整不出

我开始装的是虚拟机的fedora 11，然后又装了个真实的fedora 11

fedora 11 先是找不到ip设置，
好吧 我就用
ifconfig eth0 192.168.1.111 broadcast 192.168.1.111(这里有点怪，根据下面设的) netmask 255.255.255.0

是根据手册上的：
第一项(192.168.1.70)是目标板的临时IP(注意不要和局域网内其他IP 冲突)；
第二项(192.168.1.111)是开发主机的IP；
第三项(192.168.1.111)是目标板上网关(GW)的设置；
第四项(255.255.255.0)是子网掩码；
第五项是开发主机的名字(一般无关紧要，可随便填写)

设置的。。。。。。


nfs的设置
我的nfs文件夹是  /root/a/root_qtopia
1.修改 /etc/exports 加上
/root/a/root_qtopia *(rw,sync,no_root_squash)
2.起动：#/etc/init.d/nfs start（没有什么异常）

参数是：
param set linux_cmd_line "console=ttySAC0 root=/dev/nfs nfsroot=192.168.1.111:/root/a/root_qtopia ip=192.168.1.70:192.168.1.111:192.168.1.111:255.255.255.0:sbc2440.arm9.net:eth0:off"

然后 boot

防火墙 关了。。。。
电脑的网卡 好像 一直 不通样的

开发主机的ip是什么？

我也是n的若干天了，还是不行，给你顶一个，希望有人回答。

我也是这样子啊，有同感，不知道楼主解决了没有？！

楼主 好了没 我也遇到同样的问题了 求助啊

同样的问题，有人解决了吗？分享一下吧。谢谢啦

我用的是F9 一下就成功了。我主机ip：192.168.1.23  虚拟机ip：192.168.1.120 开发板ip：192.168.1.70  没有出现你这种情况。请问一下 ：你的虚拟机是设置的桥连接吗？就是虚拟机的上网方式是桥接吗？千万别用NAT的方式。
