菜鸟问题， nfs连接不上，请版主指教

我按照手册上试了一遍
我的设置：如下
Supervivi>param set linux_cmd_line "console=ttySAC0 root=/dev/nfs
nfsroot=192.168.1.2:/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4
ip=192.168.1.3:192.168.1.2:192.168.1.2:255.255.255.0:sbc2440.arm9.net:e
th0:off"
出现的问题如下：
eth0: link down

     device=eth0, addr=192>168.1.3, mas{=255.255.255.0, gw=192.168.1.2,

连接不上是什么原因呢？请指教，急急！

window和虚拟机上ping的通，就是挂载不上去！

为了这个问题整了一下下午，上网看了很多nfs的资料，有各种各样的设置方法，但是都不适合于我：
1。整过关闭所有的防火墙
编辑/etc/hosts.allow
允许那些你想要的主机和你的NFS服务器建立连接。下列步骤将允许任何IP地址以

192.168.0开头（因为我的ip是192.168.0.234）的主机（这里是我们的开发板）

连 接到NFS服务器上，也可以指定 特定的IP地址,加入：
### NFS DAEMONS
portmap: 192.168.0.
lockd: 192.168.0.
rquotad: 192.168.0.
mountd: 192.168.0.
statd: 192.168.0.
2.设置VMware的网卡，
3.还有很多其他的方法，
最后，实在没有办法了从头整起
才发现：主机的nfs没有启动：
即在使用nfs挂载前，先把nfs启动 /etc/init.d/nfs start
之所以会这样子，主要是手册上有这么一段：
为了每次在开机时系统自动启动该服务 可以输入#serviceconf
这一句话，影响了我！
