这个简单多了，setup里service configuration里选中nfs服务，去掉iptables，和ipchains，可是fedora10里没有ipchains的，更好办了
＊＊＊＊＊＊＊＊＊＊＊其实 这些也可以用命令来实现的
查看防火墙状态：
/etc/init.d/iptables status
暂时关闭防火墙：
/etc/init.d/iptables stop
禁止防火墙在系统启动时启动
/sbin/chkconfig --level 2345 iptables off
重启iptables:
/etc/init.d/iptables restart

nfs服务主要是服务器端portmap,nfs-utils
客户端portmap,nfs-utils
1.yum install portmap nfs-utils
2.vi /etc/exports
加上 / *(rw)
3.再启动
[root@localhost etc]# /etc/rc.d/init.d/nfs restart

nfs工作ok，但要注意再根目录下操作！！！
