5: Interfacing with the SRA

DC 900-1325I 77

5.4 Web Browser Interface

The Freeway can easily be configured as a web server to allow a standard web browser

on any client system to access Freeway menu functions. If you are proficient in HTML

and PHP, you can design a similar web browser interface to access your SRA. You may

use a web browser interface to do such functions as:

• Modify your SRA configuration files

• Access a structure within your SRA using a memory-mapped file

• Send data to your SRA using TCP/IP sockets

The Freeway can support both normal (http) and secure (https) web access, though to

protect the data which flows between the Freeway and web browsers, Protogate recom-

mends that you only use secure web access. You can do that simply by putting all of your

web pages underneath the

/usr/local/www/dataS/ subdirectory. Also, for added security,

be sure to use the

check_auth_user() function in all of your web pages. This function is

located in the

required_fns.php file.

You can start a browser interface for your SRA by creating a subdirectory within the

existing secure web server area as in the following example:

cd /usr/local/www/dataS

mount -u -o rw /usr

mkdir mysra

cd mysra

pwd

/usr/local/www/dataS/mysra

[Place your html and php files in this directory.]

chown -R www:www /usr/local/www/dataS/mysra

chmod -R 555 /usr/local/www/dataS/mysra

mount -u -o ro /usr

You may use the existing html files in /usr/local/www/dataS as examples. Once you have

created your web pages, a client system can access them with the following URL:

https://<server IP address>/mysra/
