HTTP (WEB) Service
The Communications Server incorporates a HTTP service allowing the
retrieval of Web pages stored in the unit. The HTTP service runs
on the standard TCP/IP port of 80 and can be accessed using a standard
Web browser.
To view the Web pages, the Communications Server must first be configured
on the network. That is, it must at least be given an IP address.
Then specify a URL for the Communications Server to your Web browser
using its network name or address, i.e.
http://server.stallion.com, or http://192.159.80.201
From the default Web page you have access to Online Help and Tutorial,
a search engine for topics or commands and access to downloadable utilities
stored within the Communications Server.
A forms based port configuration utility has also been incorporated
to assist with setting up standard configurations. See the Online
Help for more details on using this facility.
Relevant commands are as follows:
CHANGE INTERNET HTTPD DISABLED
The HTTPD services can be disabled with this command. By default
the HTTPD services are enabled.
CHANGE INTERNET HTTPD ENABLED
Used to re-enable the HTTPD services.
CHANGE INTERNET HTTPD HOMEPAGE 'page_name'
The default homepage provided by the HTTPD can be configured from the
command line using this command. All pages in the unit are preceded
by a '/' character. For example,
CHANGE INTERNET HTTPD HOMEPAGE '/cli?help'
would be entered in order to make the online help the default homepage.
CHANGE INTERNET HTTPD HOMEPAGE DEFAULT
Used to revert to the default homepage.
HTTP currently only supports the 'GET' method of page retrieval.
It currently only supports access to its own internal pages.
Many of the pages provided within the unit are password protected.
In order to access them you must enter a valid username and password
for the unit being accessed. A single account will always exist
on each unit. This account is 'root' and the password is the systems
privileged password (the default is 'system' on new units). Some
pages can only be accessed by privileged users due to the nature of
the information that they contain.

Flash Memory Upgrade
(for rev 6.0 firmware units only)
Flash Memory upgrading allows the Communications Server's operating
software to be upgraded to newer versions, as they become available.
The upgrade is achieved by a TFTP file transfer from a local network
system to the Communications Server. The Communications Server software
is modified so that it can erase and reprogram its Flash Memory with
the new code image.
Using Web Configuration.
Invoke the Server's setup utility by entering its IP address in a network-connected
web-browser, (i.e. http://123.456.789.001).
When the Setup front page is displayed:
Step 1.
Press the 'Setup' button. Specify a valid user name and password,
if prompted.
Step 2.
Select the 'Server' (general server setup) hyperlink from the main
Setup screen.
Step 3.
Select the 'Flash Memory Server Software Upgrade' hyperlink
from the Setup Server screen. The 'Setup Flash Memory Upgrade
File' screen is displayed. You can obtain a flash memory
upgrade image file by selecting the hyperlink on this screen. Once
obtained, you can then upgrade the flash memory using the form on
this screen. Alternately, you can obtain a Windows version of the
image from the Stallion web site (www.stallion.com). Full instructions
are included at the web site.
Step 4.
Specify the update filename and hostname. These define
the location of the flash image on a local server equiped with a TFTP
server.
Step 5.
Press the Configure button when ready. The input parameters
are implemented immediately. The setup program now confirms that the
input has been accepted by displaying the Configuration Results
screen.
Using Command Line Configuration
Perform the following:
Step 1.
NVRAM. Set the Communications Server's NVRAM setting for 'flashfile'
name and host, as follows:
CHANGE SERVER FLASHFILE {file_name} {host_name}
If host_name is not specified, the Communications Server will
use the server that supplied the IP address using BOOTP or DHCP.
Step 2.
Reboot the Communications Server. The startup boot code checks
the 'flashfile' tag of the NVRAM. If set, the unit boots into the
Flash Memory upgrade process. Otherwise it boots normally and flash
upgrade is aborted.
Step 3.
Poll. The Flash Memory upgrade service will poll the 'flashfile'
host every 5 seconds and attempt to TFTP the specified 'flashfile'
name. If the TFTP open succeeds, the Communications Server will load
the entire file and check that its checksum is valid. If it is not,
then it will continue to poll.
Step 4.
Re-TFTP Update File. If the check sum is good the Communications
Server will again TFTP the entire file. This time, the contents of
the Flash Memory are reprogrammed. If this load is successful the
Communications Server will reboot into the new operating image.
Step 5.
Reboot to old image if unsuccessful. If the new server
image is unable to be downloaded within two minutes, the Communications
Server will reboot into its current Flash Memory resident operating
image.
Specifying Timer Values
Timer values controls the refresh rate of the various monitor commands.
The TCP Keep Alive Timer determines how often the server checks existing
TCP connections for validity.
Using Web Configuration.
Invoke the Server's setup utility by entering its IP address in a network-connected
web-browser, (i.e. http://123.456.789.001).
When the Setup front page is displayed:
Step 1.
Press the 'Setup' button. Specify a valid user name and password,
if prompted.
Step 2.
Select the 'Server' (general server setup) hyperlink from the
main Setup screen.
Step 3.
Select the 'Timer Values' hyperlink from the Setup Server screen.
Step 4.
Specify the monitor timer in seconds (default 3) and TCP
keep alive timer in minutes (default 120). The default values
should be retained unless you have a specific reason for changing
them.
Step 5.
Press the Configure button when ready. The input parameters
are implemented immediately. The setup program now confirms that the
input has been accepted by displaying the Configuration Results
screen.
