[IOS] HW3 Virtual address translation and COW in fork

這次的作業需求分成兩個 task：

Task 1
Implement a custom system call to translate a virtual address to physical
address.

Task 2
Verify that "fork" uses copy-on-write in the creation of child process address
space.

# 先從 devel/git 的 ports 中安裝 git

# 同時間選取 gitweb 以提供網頁界面

# 之後遇到的設定頁照原來的 OK OK 就可以

cd /usr/ports/devel/git

make install clean

 

# 增加 git 的使用者,並指定 git 的家用目錄為 /home/git

# 同時間使用 git-shell 作為 shell 指令, uid, gid 為 9418

pw groupadd -n git -g 9418

pw useradd -n git -u 9418 -g git -c git -d /home/git -s /usr/local/libexec/git-core/git-shell -h -

 

# 新增 repo (倉庫 work),並更改屬性

chown git:git /home/git

chmod 755 /home/git

 

mkdir /home/git/work/

chmod 775 /home/git/work/

chown git:git /home/git/work/

 

# 設定除了 commit 外還可以使用額外指令的用戶

# 如果使用者只需要 commit,就可以不加進來

vi /etc/group

git:*:9418:zeuxis,neo

 

# 設定 SSH 認證金鑰,因為 git 要用到這東西

# 每個使用者的 SSH Key 也要加進 authorized_keys.

# 每個 key 為一行

mkdir /home/git/.ssh/

chmod 700 /home/git/.ssh/

 

touch /home/git/.ssh/authorized_keys

chmod 600 /home/git/.ssh/authorized_keys

chown -R git:git /home/git/.ssh/

 

# 生成指定用戶的 SSH Key

# 在安裝情況下是使用 ssh-keygen -d 生成 dsa

# 另還可用 ssh-keygen -t rsa 生成 rsa

# 生成時 Enter passphrase 無視按下 enter 即可

su username

ssh-keygen -d

su root

cat /home/username/.ssh/id_dsa.pub > /home/git/.ssh/anthorized_keys

 

# 接著設定 git 的 repo

mkdir /home/git/work/test.git

cd /home/git/work/test.git && git init --bare --shared

 

# 接著進行一個簡單的測試

mkdir /tmp/test && cd /tmp/test && git init

echo "This is a test" > index.html

git add

git commit -m 'added index.html'

 

# 之後 commit 到遠端的 repo

git remote add origin username@example.com:work/test.git

git push origin master

 

# 之後再設定 gitweb

mkdir /home/git/public_html

chmod 755 /home/git/public_html

chown git:git /home/git/public_html

cp /usr/local/share/examples/git/gitweb/git* /home/git/public_html

 

# 再設定 apache

<VirtualHost *:80>

  ServerAdmin no-reply@example.com

  DocumentRoot "/home/git/public_html"

  ServerName git.example.com

 

  <Directory "/home/git/public_html">

    Options ExecCGI

    Order allow,deny

    Allow from all

 

    DirectoryIndex gitweb.cgi

    AddHandler cgi-script .cgi

  </Directory>

</VirtualHost>

 

# 之後再編輯 gitweb.cgi

our $projectroot = "/home/git/work";

our $home_link_str = "work";

our $site_name = "git.example.com"

our $projects_list_description_width = 40; # 調整 description 空間

 

# 修改 test.git 的描述

echo "test.git" > /home/git/work/test.git/description

 

# 修改 test.git 的 owner

vim /home/git/work/test.git/config

 

# 在其後面加入

[gitweb]

owner = zeuxis

url = git://git.example.com/work/test.git

url = username@git.example.com:work/test.git

 

# 最後就是設定 Git protocol

# 在 /etc/rc.conf 最後加入這段

git_daemon_enable="YES"

git_daemon_directory="/home/git"

git_daemon_flags="--syslog --base-path=/git --export-all"

 

# 之後啟動 Git Daemon

/usr/local/etc/rc.d/git_daemon start

 

# 如果以上面這句子會出現停在 starting 的字眼可以改為以下句式

# 送出後接兩下 Enter 結束即可

/usr/local/etc/rc.d/git_daemon start &

 

# 檢查是否在執行

ps -eaf | grep -v grep | grep git

 

# 如有東西就可以再測試可否使用了

cd /tmp/test

rm -Rf *

git clone git://git.example.com/work/test.git

• Notice that user can use both http and https portocal to access this page.

• When access http://yourdomain1/private/, user need enter id "nctucs" and password "sahw4" which is implemented by .htaccess. And it will show the text “It’s my secret.”

• System user sysadm can put file at ~/WWW/ and others can access it by visiting http://yourdomain1/~sysadm/. sysadm's password is your student id.

• Your git website url is http://yourdomain2/gitweb

• For demo, you need to put a git repository named “sademo.git”. And it’s decription is “This repository is for sa demo.”.

• On your website, enter the sademo.git will show URL information, it’s URL is http://yourdomain2/gitweb/sademo.git.

• You can clone and push your repository by http://yourdomain2/gitweb/sademo.git and password is your student id.

• Users use cookie authentication when access your phpMyAdmin site http://yourdomain1/phpMyAdmin/
• (You need to add a MySQL user for authentication).
• Create another user with limited privilege
• And notice that if others access http://yourdomain2/phpMyAdmin/, they can not access it.
• Only 140.113.*.* can access it
• But 140.113.235.* can’t access it

• Redirect http://yourdomain1/ILoveSA to http://help.cs.nctu.edu.tw/ 
• But http://yourdomain2/ILoveSA will not redirect .
