Harvey2 can be used for testing Linux versions of mySQL, PERL, PHP, Python, Ruby as well as displayng web pages

Use the Linux Apache server on harvey2 replacing the typical bingweb with harvey2:
http://harvey2.cc.binghamton.edu/~<your user-id>

• You must have a valid bingsuns account that works on a PODS lab machine and BingSuns.
• Either command line ssh client components installed on Windows OR be starting on a Linux or Unix machine ssh -X <your user-id>@harvey2.cc.binghamton.edu
  
• The -X will allow you to run X-applications on Harvey2, IF you are coming from a Linux box and possible a Mac.
  ON a windows computer you will need an X client running to start X-apps.

If you don't already have it, install the SSH client for windows supplied by BU.
Or install an SSH package on your linux machine.

1. Click on the SSH icon :
    
   
2. 
    
   Click on the Quick Connect button :
    
   
3. 

   Enter harvey2.cc.binghamton.edu	in the Host Name: entry point
   Enter your user-id	in the User Name: entry point
   Enter 22	in the Point Number: entry point (it should be there already)
   Select Password	in the Authentication Method entry point (if it is not already selected)

   Click on the Connect button :
    
   
4. 
    
   You will get a warning screen the first time in.   Hit the Yes button

These are simple directions to guide you to log in for the first time. There are many other features and functions in the SSH client that you can learn and explore. In particular the FTP part of the client. This is essential to transferring files. You can also save login and ftp configurations for later use that will not require filling all the information in over and over again.

If you don't already have it, install the PUTTY windows application supplied by BU.
There are several SSH GUI's in Linux.

1. Click on the Putty icon :
    
   The Putty screen will appear:

These are simple instructions to help you with your first log in.

• Mac Orchard's FTP app list
• Max SSH for OS X @ Panix.Com
• Graphic Max OS X SSH page

1. This will use mod_perl to execute code. Many references can be found on-line
2. No magic line (#!/usr/bin/perl) should be used.
3. A .pl extention should be used.
4. These should not be in the cgi-bin directory.

• mod_php
  1. A script can be all PHP or embedded in HTML.
  2. A magic line (#!/usr/bin/php) should be used,
     If a magic line is used it will be treated as part of the text.
  3. A .php extention must be used.
  4. A php script can be placed in your public_html file structure.
  5. Calling a php script by the name of a php function can have unexpected results, or not.
   
  
• php as a cgi script
  1. A magic line (#!/usr/bin/php-cgi) must be used.
  2. It is a good practice to use a .cgi extention on these scripts. [[editors note: JH says this is a lie.]]
  3. The file must be executable (chmod u+x <filename>.php)
  4. A script can be all PHP or embedded in HTML.
  5. It is a good practice to keep .cgi scripts in your cgi-bin directory.

Python currently should only be used in cgi-bin scripts.

1. This will use mod_ruby to execute code. Many references can be found on-line
2. No magic line (#!/usr/bin/ruby) should be used.
3. A .cbx extention should be used.
4. These should not be in the cgi-bin directory.

1. Scripts for any installed language, as a good practice, should be in your cgi-bin directory under your public_html directory.
   ~<youruserid>/public_html/cgi-bin
2. Typically and as a good practive use a .cgi extention.
3. A magic line must be at the top of the script to indicate which and where the language executable is located.
   The following are correct magic line's for Harvey2.
   • #!/usr/bin/perl             # current version 5.10
   • #!/usr/bin/php             # current version 5.2
   • #!/usr/bin/python2.3
   • #!/usr/bin/python2.5   # current default
     #!/usr/bin/python       # uses default
   • #!/usr/bin/python3.0
   • #!/usr/bin/ruby1.8     # current default
     #!/usr/bin/ruby1.8     # uses default
   • #!/usr/bin/ruby1.9
4. The script needs only and should only be executable for user.
   chmod u+x <filename>.cgi
   chmod go-x <filename>.cgi
5. Files can be written from a script.
