Creating A Web Site at NJIT
Professor Blank
Starting Your Homepage
• A Web page should be already set up for you with a
public_html directory that has the right permissions to
create and use when your UCID account is created.
• If yours is not set up or you want more information, go to
http://web.njit.edu.
• From the menu on the left select the last topic,
User_Homepage. Follow the instructions there.
Servers Available to Students
• There are 38 public access AFS clients running the current
Solaris operating system available to students.
sunlab1.njit.edu through afs35.njit.edu are for academic use.
prophet.njit.edu has Oracle installed for database courses.
web.njit.edu is a web server that allows others to access
your web site in public_html. harp.njit.edu is a special
purpose web server that allows sound and video, which are
blocked on web. There are also 29 Linux servers at
osl1.njit.edu through osl29.njit.edu All use the same login
and file structure, so any files you create on one server can
be read, executed and changed on any other. Those
students who have used the Sun Lab machines under their
old URLs of afs1 through afs35 should know that all such
odd numbers now connect to afsconnect1.njit.edu and all
even numbers to afsconnect2.njit.edu.
Security Requirement
• Off-campus access to AFS must use Secure Shell (ssh) over a
Virtual Private Network (VPN).
• To download software (including regular VPN) you must use
VPN. This is possible with webvpn. Go to
http://webvpn.njit.edu or follow the instructions at
http://telecom.njit.edu/vpn/WebVPNInstall.html
• Once you have a VPN connection, you can download the Secure Shell
software at http://ist.njit.edu/software/index.php
Connect to UCS and Log In
• Use the Secure
Shell Client and
your UCID
username and
password to log
on the one of the
UCS machines,
such as
afs23.njit.edu:
Use Secure FTP
• You can use the
Secure File
Transfer Protocol
program to
upload your
materials. The
SSH Secure File
Transfer Client is
provided when
you get SSH.
Use Secure FTP
• The SSH FTP Client is a simple drag and drop interface.
Most students should have little trouble figuring it out.
• If you do have trouble, try the Help selection on the menu. If
that does not work, post your problems on Web Board and I
will add enough detail to this presentation to guide you
through it.
• It is recommended that you set up multiple connection
profiles. The systems are public access and individual
machines may be unavailable, yet others may still be
accessed.
Your FTP address
• It helps to know the base address of your site. Mine
is:
/afs/cad/u/g/b/gblank/public_html
• The only thing that you need to change is the
/u/g/b/gblank/ part. In my case, the u is for
users, so yours will also be u. The g and b are the
first two characters of my username. Use the first two
characters of yours. The next section is your
username. If your user name is xyz123 then you
would specify:
/afs/cad/u/x/y/xyz123/public_html
Create a Menu
• Your menu file should be an html file named index.html
or menu.html. A Web Browser can find either of those
automatically.
• I recommend that you create a directory for your projects,
such as /cs602, with a separate directory for each
assignment, such as /ch4. You can have an index.html
file at your base directory that can load the other files. If you
go to my Web Site and "view source" in your browser you
can see how I do it. That will give you directories like:
/afs/cad/u/x/y/xyz123/public_html/cs602/ch5
Using Unix
• Use Unix commands to create your directories: You can
find a list by searching the Web.
• mkdir - create a directory
• cd – change directory
• ls – list files
• cp – copy a file
• mv – rename or move a file
• rm – delete (remove) a file
• setacl – give permissions to read/write a file
File Permissions
• For people to read files on your Web Site, you may have to
set the file permissions.
• The normal Unix permissions like chmod are ignored by
AFS. Instead, it uses an access control list managed with
the command setacl.
• For a description of setting permissions, go to
http://web.njit.edu. From the menu on the left select
the first topic, AFS, then subtopic CheckPerms, then
subtopic How to set AFS permissions.
Creating and Accessing Files
• I recommend that you use SunLab1 through SunLab36 or
OSL1 through OSL29 to develop your website and do your
course homework. The single digit numbers tend to be more
heavily used than higher numbers, so you can avoid
congestions by using avoiding Sunlab 1 or 2 or OSL 1 or 2.
• If you create a web site, others can view your web pages in
public_html and its subdirectories on WEB, or on HARP if it
uses sound or video.
Finding Your Web Site
• Your Web site will be at
http://web.njit.edu/~xyz123/index.html with a full path
of http://web.njit.edu/~xyz123/cis602/hw5/hw5.java
etc. Of course, you will have to substitute your username
for xyz123.
• Don’t forget the Tilde ( ~ )!
Public Access to Web Site
• Other users can find your Web site at
http://web.njit.edu/~xyz123/ if you have an html
file named index.html or menu.html in your
public_html directory. Otherwise, they will also have to
know the name of the file to run. Of course, they will have
to substitute your username for xyz123.
• If your Web site has sound or video they can use
http://harp.njit.edu/~xyz123/
A Quick and Dirty Home Page
• For a fast start to creating your home page, just steal
my sample home page at
http://web.njit.edu/~gblank/cs602/StealThis.html
• An sample index.html is already installed for you,
and you can simply edit that.
• Follow the instructions on my page and edit it to
create your own menu. If you do not have an HTML
editor, you can use Microsoft Word, as long as you
select html as the file type when you save the file.
Note:
• You should not use a Web browser on SunLab1 through
SunLab36 for http at all. Those systems are reserved for
creating your programs, or running homework programs in a
Unix shell. The only AFS systems you should be using to
access Web services are http://web.njit.edu and
http://harp.njit.edu . This will allow more people to use the
system without overloading it. You can see the Solaris and
Linux systems for yourself and work on them directly on the
second floor of GITC.
