Apache web server allows server access based upon various conditions. For example you just want to restrict access to url http://payroll.nixcraft.in/ (mapped to /var/www/sub/payroll directory) from 192.168.1.0/24 network (within intranet).
Apache provides access control based on client hostname, IP address, or other characteristics of the client request using mod_access module.
Open your httpd.conf file:
# vi /etc/httpd/conf/httpd.confLocate directory section (for example/var/www/sub/payroll) and set it as follows:
Allow from 192.168.1.0/24
Allow from 127
- Order allow,deny: The Order directive controls the default access state and the order in which Allow and Deny directives are evaluated. The (allow,deny) Allow directives are evaluated before the Deny directives. Access is denied by default. Any client which does not match an Allow directive or does match a Deny directive will be denied access to the server.
- Allow from192.168.1.0/24: The Allow directive affects which hosts can access an area of the server (i.e. /var/www/sub/payroll/). Access is only allowed from network 192.168.1.0/24 and localhost (127.0.0.1).
Save file and restart apache web server:
# /etc/init.d/httpd restart

You need to use IIS 6.0 Manager for Windows XP. With IIS 6.0 Manager for Windows XP, administrators can remotely manage an IIS 6.0 server from a Windows XP Professional desktop computer system.
According to Microsoft documentation, “With IIS 6.0 Manager for Windows XP, administrators can remotely manage an IIS 6.0 server from a Windows XP Professional workstation. This tool only installs a snap-in for Microsoft Management Console and its associated DLLs and documentation; it does not install the complete IIS 6.0 server on your local computer”
You can download (3.7 MB) Internet Information Services (IIS) 6.0 Manager for Windows XP from Microsoft web site.
How do I test php installation with a phpinfo() page under UNIX / Linux Apache / nginx / lighttpd web server?
Q. How do I run a shell script from a web server or a web page under Apache or Lighttpd websever?
A. In order to run a shell script from a web page you need Apache web server configured with cgi access. Apache CGI allows documents/files in cgi-bin directory treated as application and run by server when requested rather than as documents sent to the client.. It means if you put shell script in cgi-bin directory then you are able to execute them from a web page. However, you cannot simply run shell script from a web. You need to send or print the MIME type before outputting data to the web browser from shell script. You need to add following line to script before you get output back to browser:
echo "Content-type: text/html"
Here is the script that can displays today’s date and other information related to your shell script:
# get today's date
# You must add following two lines before
# outputting data to the web browser from shell
echo "Content-type: text/html"
echo "Today is $OUTPUT <br>"
echo "Current directory is $(pwd) <br>"
echo "Shell Script name is $0"
Save the script in your cgi-bin directory and execute it from web page.
