2. usage notes (in Ubuntu9.10 and Fedora10 )

(1) nfs mount in local host ( ubuntu )

i. mkdir nfs

root@vinco:/# mkdir nfsdirroot@vinco:/# chmod 777 -R /nfsdir/root@vinco:/# ll -a nfsdirtotal 8drwxrwxrwx  2 root root 4096 2011-07-25 11:45 .drwxr-xr-x 22 root root 4096 2011-07-25 11:45 ..

ii.add a line as below:

root@vinco:/home/vinco# vim /etc/exports /nfsdir *(sync,rw,no_root_squash)

iii. restart the nfs:

root@vinco:/home/vinco# /etc/init.d/nfs-kernel-server restart * 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 "*:/nfsdir".  Assuming default behaviour ('no_subtree_check').  NOTE: this default has changed since nfs-utils version 1.0.x                                                                                                                                                                 [ OK ] * Starting NFS kernel daemon     

iv. restart the portmap

root@vinco:/home/vinco# /etc/init.d/portmap restartRather than invoking init scripts through /etc/init.d, use the service(8)utility, e.g. service portmap restartSince the script you are attempting to invoke has been converted to anUpstart job, you may also use the restart(8) utility, e.g. restart portmapportmap start/running, process 800root@vinco:/home/vinco# service portmap restartportmap start/running, process 800

v. try mount in local machine(192.168.152.144)

--------in console one:

root@vinco:/# cd nfsdir/root@vinco:/nfsdir# touch nfs.txtroot@vinco:/nfsdir# lltotal 0-rw-r--r-- 1 root root 0 2011-07-25 12:25 nfs.txt

--------in anther console

root@vinco:/home/vinco# mount -t nfs 192.168.152.144:/nfsdir/  /mnt/root@vinco:/home/vinco# ls /mnt/nfs.txt
