最近學習NFS，用本地測試.
以下是我的測試過程



環境 ubuntu 10.4?? vm 7.1
終端
ifconfig 得到 ubuntu資料
INET ADDR 192.168.0.4
BCAST?? 192.168.0.255
MASK 255.255.255.0

一 安裝NFS
$ sudo apt-get install nfs-kernel-server
$ sudo apt-get install nfs-common

二 配置NFS
1 $ sudo dpkg-reconfigure portmap , 對Should portmap be bound to the loopback address? 選N
2 $ sudo?? /etc/default/portmap 末行清除 "-i 127.0.0.1"

三 配置hosts.deny
$ sudo vi?? /etc/hosts.deny
文本末添加
### NFS DAEMONS
?? portmap: ALL
?? lockd: ??? ALL
?? mountd:?? ALL
?? rquotad: ALL
?? statd: ??? ALL

四 配置hosts.allow
?? $ sudo vi /etc/hosts.allow
文本末加入
### NFS DAEMONS
?? portmap: 192.168.0.
?? lockd: ??? 192.168.0.
?? rquotad: 192.168.0.
?? mountd:?? 192.168.0.
?? statd: ???? 192.168.0.
$ sudo /etc/init.d/portmap restart 重啟portmap daemon.
顯示如下
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the restart(8) utility, e.g. restart portmap
portmap start/running, process?? XXXX

五 配置/etc/exports
$ sudo vi /etc/exports
文本末添加
/home/work *(rw,sync,no_root_squash)

/home/gxj/IPNC2.6/ *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
chmod 777 -R /home/work
$ sudo showmount -e
顯示 clnt-create : RPC : Program not registered

$ sudo?? exportfs -r 更新

$ sudo?? showmount 192.168.0.4 -e
顯示
Export list for 192.168.0.4:
/home/work *

六 啟用
?? $ sudo /etc/init.d/nfs-kernel-server restart 重啟nfs服務
顯示如下
* Stopping NFS kernel daemon ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ????????????? [ OK ]
* Unexporting directories for NFS kernel daemon... ?? ?? ?? ?? ?? ?? [ OK ]
* Exporting directories for NFS kernel daemon... ?? ?? ?? ?? ?? ?? ?? ?? ??
?? exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/home/work".
?? Assuming default behaviour ('no_subtree_check').
?? NOTE: this default has changed since nfs-utils version 1.0.x
????????????????????????????????????????????????????????????????????????

* Starting NFS kernel daemon????????????????????????????????????????????????????????? [ OK ]
