（亲测有效）在SecureCRT终端挂载Ubuntu时遇到的问题

ubuntu侧
root@ubuntu:/home# /etc/init.d/rpcbind restart
bash: /etc/init.d/rpcbind: No such file or directory
解决方法：
root@ubuntu:/home# apt-get install nfs-kernel-server
root@ubuntu:/home# /etc/init.d/rpcbind restart
[ ok ] Restarting rpcbind (via systemctl): rpcbind.service.
root@ubuntu:/home# /etc/init.d/nfs-kernel-server restart
[ ok ] Restarting nfs-kernel-server (via systemctl): nfs-kernel-server.service.

CRT侧
root@OpenWrt:~# busybox mount -t nfs -o nolock 192.168.2.13:/home/work /mnt/
mount: mounting 192.168.2.13:/home/work on /mnt/ failed: No such device
解决方法：内核配置打开NFS，如图所示：

root@OpenWrt:~# busybox mount -t nfs -o nolock 192.168.2.13:/home/work /mnt/
mount: mounting 192.168.2.13:/home/work on /mnt/ failed: Protocol not supported
解决方法：

内核配置打开nfs-v3，如图所示：

root@OpenWrt:~# busybox mount -t nfs -o nolock 192.168.2.13:/home/work /mnt/
mount: mounting 192.168.2.13:/home/work on /mnt/ failed: Permission denied
解决方法：
打开/etc/exports文件，在最后加一行：
/home/work *(rw,sync,no_root_squash)
重启nfs服务：
/etc/init.d/nfs-kernel-server restart
执行挂载命令即可正常挂载，最后使用mount查看挂载情况
