    解决办法:
    在主机的/etc/hosts文件中增加一行名称解析內容:
    目标板IP 根文件系统文件名
    比如:我的/etc/hosts增加后变为:

    127.0.0.1	localhost
    127.0.1.1	ubuntu
    
    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    
    
    #增加下面这句:目标板IP, nfs共享文件夹
    192.168.1.17 /work/nfs_root/
