    我们买了贵公司的ARM开发试验箱,现正在学习。关于linux的试验,出现了问题,希望给予答复!


pc上装的redhat9.0
关于NFS的设置是这样的:
1) PC网卡的地址是172.18.154.111
2)防火墙是关闭的
3)去掉了iptables  ip6tables ipchains
4)NFS服务设置为
/home/ARMwork            172.18.154.222(rw,sync)
/home/ARMwork            172.18.154.111(rw,sync)

5)MagicARM开发板的ip为172.18.154.222

一:
在PC上可以实现mount如下命令
[root@localhost root]# mount 172.18.154.111:/home/ARMwork /home/ARM/t
[root@localhost root]# mount
/dev/hda10 on / type ext3 (rw)
none on /proc type proc (rw)
USBdevfs on /proc/bus/USB type USBdevfs (rw)
/dev/hda8 on /boot type ext3 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/shm type tmpfs (rw)
/dev/hda6 on /mnt/winE type vfat (rw,noexec,nosuid,nodev,iocharset=cp936)
/dev/hda7 on /mnt/winF type vfat (rw,noexec,nosuid,nodev,iocharset=cp936)
/dev/hda5 on /mnt/winD type vfat (rw,noexec,nosuid,nodev,iocharset=cp936)
/dev/hda1 on /mnt/winC type vfat (rw,noexec,nosuid,nodev,iocharset=cp936)
172.18.154.111:/home/ARMwork on /home/ARM/t type nfs (rw,addr=172.18.154.111)
二:
在pc上用交叉线可以ping到开发板
[root@localhost root]# ping 172.18.154.222
PING 172.18.154.222 (172.18.154.222) 56(84) bytes of data.

You have new mail in /var/spool/mail/root
[root@localhost root]#
在开发板上可以平到PC机
[root@localhost root]# ping 172.18.154.111
PING 172.18.154.111 (172.18.154.111) 56(84) bytes of data.

64 bytes from 172.18.154.111: icmp_seq=5 ttl=64 time=0.028 ms

rtt min/avg/max/mdev = 0.024/0.027/0.034/0.006 ms

三 : 在开发板上mount pc机上的文件一直不成功,请问是什么原因??????(用交叉线直连)
/usr> portmap&
[27]
/usr> mount -t nfs 172.18.154.111:/home/ARMwork /mnt -o nolock
mount: RPC: Timed out
mount: nfsmount failed: Bad file descriptor
NFS: mount program didn't pass remote address!
mount: Mounting 172.18.154.111:/home/ARMwork on /mnt failed: Invalid argument
pid 28: failed 256

请问这是什原因,????
希望能给于解决!!
