  2. How to post web pages on the Internet?

    To post web pages, you need to put all web files into a "public_html"  and set permission correctly.
    First, you need to email IT help to create "data" folder for you if you don't have one yet.  The new location is
    /usr/local/data/your_username
    ie/ /usr/local/data/john.foo
    After you have your "data" folder, ssh to our Unix server and start setting it up.
    ie. ssh john.foo [at] stat.ubc.ca
    $ mkdir /usr/local/data/john.foo/public_html
    $ ln -s /usr/local/data/john.foo/public_html   ~/john.foo/public_html
    Folder permission is 711 or 755 (less secure)
    $ chmod 711 /usr/local/data/john.foo/public_html
    $ chmod 711 ~/john.foo
    Notes: To find out where your home directory is type: 'pwd' 

    In the " public_html" folder, a file called "index.html". This file is the main web page.
    Set permission to File is 644
    $ cd /usr/local/data/john.foo/public_html
    $ vim index.html
    $ chmod 644 index.html

    Your Website is
    http://www.stat.ubc.ca/~your_username/

    Note: You can also have a webpage on unixlab,our Undergradute server. Can be useful, for keeping online material for the course you're TAing. For example, web files for user stat200 will be in /home/www/stat200/public_html

    and it can be accessed from the web as http://unixlab.stat.ubc.ca/~stat200

  3. What editor is needed to edit a web file?

    On our Unix systems, Vim and Emacs.  Opensource package such as Seamonkey or commercial products
    such as Adobe Dreamweaver and Microsoft Expression are very good.

Q: Departmental Disclaimer and Personal Web Page policy
Q: How to automatically post a bunch of photos in your webpage?

You can use the scripts makethumbs.sh and rotate.sh provided by http://www.molenda.com/makethumbs/. The basic procedure is given below.

STEP 1.

Download makethumbs.sh and rotate.sh to a directory, ~/mytools say, from http://www.molenda.com/makethumbs/.

STEP 2.

Change the modes of the files makethumbs.sh and rotate.sh by typing command:

chmod +x ~/mytools/*.sh

STEP 3.

Create a directory, ~/myphoto say. And copy all your jpg files in this directory. This directory only contains the photos you want to post.

STEP 4.

Run the following command in the directory ~/myphoto:

~/mytools/makethumbs.sh

STEP 5.

Make a hyperlink to ~/myphoto/index.html.

That's simple!

Notes:

  • If you want to change the title of the photo webpage, captions and descriptions of the photos, you can modify the file ~/myphoto/description.txt and re-type the command ~/mytools/makethumbs.sh.
  • If you want to rotate some photos, use the script rotate.sh. For example, the command cp photo1.jpg photo1.jpg.bak cp photo2.jpg photo2.jpg.bak ~/mytools/rotate.sh r photo1 photo2 ~/mytools/makethumbs.sh will rotate photo1.jpg and photo2.jpg anti-clockwise 90 degree. Since rotate.sh may modify the original file, it's better to make a backup for the file you want to rotate. You can type rotate.sh --help to obtain the usage of the script rotate.sh. The following is the copy of the usage information: bash-2.04$ ./rotate.sh --help Usage: rotate.sh [-p|-o] <-r|-l> file1.jpg file2.jpg file3.jpg ... -p | --preserve Do not touch original image, even if we can do so safely. -r | --rotate-right Rotate images to the right (90 deg clockwise) -l | --rotate-left Rotate images to the left (90 deg counter clockwise) rotate.sh tries to rotate images losslessly if possible. Lossless rotation is possible on this system, so it is the default. You can override this behavior with -o (overwrite) or with -p (preserve) Filenames can be any unique part of the filename. e.g. if DSCN0532.jpg exists, 'rotate.sh r 32' will rotate it 90 degrees clockwise. You can find the latest version of this program at http://www.molenda.com/ This is version v1.22 of rotate.sh.
  • Each time you make some changes (e.g. adding new photos, modifying the descriptions, or rotating photos), you have to re-run the command ~/mytools/makethumbs.sh.
Q: How to create a password-protected website?

Use "be.stat.ubc.ca"
$ssh  username@stat.ubc.ca

Here are the simplified instructions on how to make a password protected web folder for our site:

1) Create the private web folder in your web directory. This is the directory for which you want to curtail access to.

$mkdir -p  /nfs/fil-data/username/public_html/private
$mkdir -p  /nfs/fil-data/username/keys

2) Within this private web directory, create a file called

.htaccess

which contains the following text:

SSLRequireSSL
AuthType Basic
AuthName "Title of your protected folder"
AuthUserFile /nfs/fil-data/username/keys/.htpasswd
Require valid-user
ErrorDocument 403 https://www.stat.ubc.ca/~username/private/
 
Notes: www.ugrad.stat.ubc.ca 
DONOT use "SSLRequireSSL" and "ErrorDocument 403 https://www.ugrad.stat.ubc.ca/~myusername/private/"
3) To create a password file with an initial user and password, use this command:
	$/usr/local/bin/htpasswd -c /nfs/fil-data/username/keys/.htpasswd user1
	... enter password for users1

To add additional users, run this command:

$/usr/local/bin/htpasswd /nfs/fil-data/username/keys/.htpasswd user2
	... enter password for users2
Note: There is no "-c" for creating second users

To delete users
$/usr/local/bin/htpasswd  -D /nfs/fil-data/username/keys/.htpasswd users

4) Make sure your files and directories have the correct permissions:

	$chmod 0711 /nfs/fil-data/username/public_html/private
	$chmod 0644 /nfs/fil-data/username/public_html/private/.htaccess
	$chmod 0711 /nfs/fil-data/username/keys
	$chmod 0644 /nfs/fil-data/username/keys/.htpasswd

 

Test the setup by using a browser and going to your private web folder:

http://www.stat.ubc.ca/~username/private/

It is important to note that this will offer some protection of your web files against unauthorized access via a web browser, but it does not protect you from StatNet users reading your files since they can go directly to your web directory via regular filesystem commands like 'cd' and 'less' and access your files.

In this case, you ought to encrypt your files (for example, by using the zip utility to created an encrypted zip archive). This is for for highly confidential information that need to be desseminated.
