最近几天终于把ubuntu LTS(long term version) 10.4 给机子安装完毕
然后把要点总结一下

1. 通过df -h 查看分区, 查看mount point 和 分区大小
2. 两个primary partition, \  , swap, 其余都是logical partitions
3. 安装NIS和NFS
NIS:
首先安装nis,
dpkg-reconfigure nis
Enter Domainname as: fishy.domain

Edit /etc/hosts to include: <server-ip-address> server-name
128.180.35.235 shark.ie.lehigh.edu shark

Edit /etc/adduser.conf to change to: FIRST_UID=6000
so that new uids on the client dont conflict with nis-ids.
Edit /etc/passwd to add as the last line:
+::::::
Edit /etc/group to add as the last line:
+:::
Edit /etc/shadow to add as the last line:
+::::::::
Do ypcat passwd so see if nis is functional.
2. NFS

First move /home directory to something like /localhome. Make necessary changes in /etc/passwd so that locally created users are not affected.

在/passwd这个文件中修改 beluga的路径, 将/home改成 /localhome
Edit /etc/auto.master to include:
/home /etc/auto.home --timeout=600

Edit /etc/auto.home to include:
* -rw,intr,hard,tcp shark.ie.lehigh.edu:/home/&
Now do umount /home. And then, /etc/init.d/autofs start
用apt-get install安装autofs
service autofs start /stop
tip:
apt-get remove nfs-common
apt-get install nfs-common
fstab -> file system table
shark.ie.lehigh.edu:/home  /home nfs rw, intr, hard, tcp 0 0
which means mount from shark.ie.lehigh.edu:/home to /home in the current file system
下一步就是要安装软件AFS
