我试图让一个基本的 nfs4 在两台机器之间工作（让我们称它们为server和client）。我已经通过信函遵循了本手册 ，但无济于事。这是我得到的：
root@server#: tail -n 2 /etc/exports
/export client-ip/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
/export/users client-ip/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
root@server#: showmount --exports
Export list for server-ip:
/export/users client-ip/24
/export client-ip/24
服务器端似乎没问题。目录存在，它们的权限被授予 (775)。地址（client-ip和server-ip）是数字 - 出于显而易见的原因，这里用首字母缩写词替换。接下来，客户端：
root@client#: mount -v -t nfs4 server-ip:/export /opt/nfstest
mount.nfs4: timeout set for Thu Apr 14 15:52:31 2011
mount.nfs4: text-based options: 'clientaddr=client-ip,addr=server-ip'
mount.nsf4: mount(2): No such file or directory
mount.nfs4: mounting server-ip:/export failed, reason given by server:
No such file or directory …
