我正在尝试安装NFS服务器，其中服务器端是运行MacOS Mojave的笔记本电脑，客户端是运行由Yocto构建的Ubuntu Linux的SAMA5D27板。
我已经为SAMA5D27板分配了IP地址，并且能够从笔记本电脑ping SAMA5D27板，反之亦然。因此它们彼此可见。
在笔记本电脑上，我已经编辑了/ etc / exports文件，内容如下：
conn.Open()然后我通过运行以下命令在笔记本电脑上启动nfsd：
/Users/mntpnt -network 192.168.1.8 -mask 255.255.255.0
在SAMA5D27上，我运行以下命令（服务器IP：192.168.1.8）
$ sudo nfsd enable
$ sudo nfsd start
$ sudo nfsd status
nfsd service is enabled
nfsd is running (pid 24885, 8 threads)
它显示：
$ showmount -e 192.168.1.8
然后我尝试在客户端SAMA5D27上使用以下命令进行安装：
Export list for 192.168.1.8:
/Users/mntpnt 192.168.1.8
我还尝试编辑/ etc / exports中的权限，使其现在显示为：
$ sudo mount -v -t nfs 192.168.1.8:/Users/mntpnt /mntpnt
mount.nfs: timeout set for Thu ApNF 9 00:37:14 2020S: bad mount option value specified: minorversion=1
mount.nfs: trying text-based options 'vers=4.2,addr=192.168.1.8,clientaddr=192.168.1.100'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'vers=4,minorversion=1,addr=192.168.1.8,clientaddr=192.168.1.100'
mount.nfs: mount(2): Invalid argument
mount.nfs: trying text-based options 'vers=4,addr=192.168.1.8,clientaddr=192.168.1.100'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'addr=192.168.1.8'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 192.168.1.8 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: portmap query retrying: RPC: Timed out
mount.nfs: prog 100005, trying vers=3, prot=6
mount.nfs: trying 192.168.1.8 prog 100005 vers 3 prot TCP port 872
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 192.168.1.8:/Users/mntpnt
，然后我也在MacOS上做了一个/Users/mntpnt -network 192.168.1.8 (rw, no_root_squash) -mask 255.255.255.0
。
所以现在SAMA5D27上的访问被拒绝错误消失了，但是我现在根本没有得到响应：
$ sudo nfsd restart在我发现连接超时之前，这似乎一直在循环。
任何想法可能出了什么问题？
