uclinux NFS問題：mount不能成功 MagicARM2000 060070507150487 |
| 作者：speedon 欄目：MCU技術 |
我們買了貴公司的arm開發(fā)試驗箱，現正在學習。關于linux的試驗，出現了問題，希望給予答復！ pc上裝的redhat9.0 關于NFS的設置是這樣的: 1) PC網卡的地址是172.18.154.111 2)防火墻是關閉的 3)去掉了iptables ip6tables ipchains 4)NFS服務設置為 /home/armwork 172.18.154.222(rw,sync) /home/armwork 172.18.154.111(rw,sync) 5)MagicARM開發(fā)板的ip為172.18.154.222 一: 在PC上可以實現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上用交叉線可以ping到開發(fā)板 [root@localhost root]# ping 172.18.154.222 PING 172.18.154.222 (172.18.154.222) 56(84) bytes of data. 64 bytes from 172.18.154.222: icmp_seq=1 ttl=255 time=0.492 ms 64 bytes from 172.18.154.222: icmp_seq=2 ttl=255 time=0.458 ms 64 bytes from 172.18.154.222: icmp_seq=3 ttl=255 time=0.405 ms 64 bytes from 172.18.154.222: icmp_seq=4 ttl=255 time=0.444 ms 64 bytes from 172.18.154.222: icmp_seq=5 ttl=255 time=0.427 ms --- 172.18.154.222 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3996ms rtt min/avg/max/mdev = 0.405/0.445/0.492/0.032 ms You have new mail in /var/spool/mail/root [root@localhost root]# 在開發(fā)板上可以平到PC機 [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=1 ttl=64 time=0.034 ms 64 bytes from 172.18.154.111: icmp_seq=2 ttl=64 time=0.024 ms 64 bytes from 172.18.154.111: icmp_seq=3 ttl=64 time=0.026 ms 64 bytes from 172.18.154.111: icmp_seq=4 ttl=64 time=0.026 ms 64 bytes from 172.18.154.111: icmp_seq=5 ttl=64 time=0.028 ms --- 172.18.154.111 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4016ms rtt min/avg/max/mdev = 0.024/0.027/0.034/0.006 ms 三 : 在開發(fā)板上mount pc機上的文件一直不成功,請問是什么原因??????(用交叉線直連) /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 請問這是什原因,???? 希望能給于解決!! |
