SmsNetAdmin is a completely hardware device for the 24-hour monitoring of secure network services.
It keeps the workings of servers or TCP/IP services (Web, SMTP, POP, FTP, etc.) under constant control, detecting any blocks or malfunctions instantly. In addition it is capable of controlling the room temperature, detecting problems with air-conditioning systems, and keeping tabs on equipment outside of the network, such as anti-intrusion sensors or smoke detectors.
The presence of two "electronic switches" - which can be operated remotely via SMS text message, or automatically when an alarm event selected by the user takes place - allows the restoration of normal working of devices such as routers and network switches to be attempted, even in the absence of surveillance personnel.

Up to 12 recipients can be notified of alarms by e-mail and SMS text message, so they are informed immediately about problems. For each alarm one notification is sent when the event happens, as well as an end of alarm notification once the normal situation is restored.

Along with this emergency alert system, SmsNetAdmin provides a continuously updated webpage showing the general situation of all the equipment under its control; in this way it is easy to integrate the information into a company intranet or existing website, making it possible to check the state of affairs simply by connecting to the internet.

Extremely easy to install, SmsNetAdmin is inserted as a simple network device on the LAN and is operational straight away. It can be controlled and configured both via SMS text messages and through an application produced using Macromedia Flash.

The setup is performed using standard HTTP commands, for which instructions are provided: in this way you can construct your own HTML pages or a Flash configuration and control application, which can then be integrated into a company intranet or existing website.

Main features:

• Control over 128 servers or network services
• Control of environment temperature, with detection of crossing of minimum and maximum thresholds. Measuring range from -10°C to 70°C, with accuracy of +/- 0.5°C
• Control of environmental humidity. Measuring range from 0 to 100% RH (Relative Humidity), with accuracy of +/- 3.5
• % Sending of individual alarm statuses and notifications of return to within normal functioning parameters by SMS text message and e-mail
• Multiple alarm notification facility, to ensure a clear view of the problem
• Global status of controlled services provided through HTML pages
• Can be completely configured and controlled via web, through a Flash interface or using webpages created by the user
• Can be configured and controlled via SMS text message
• Extremely small size (just 170x120x40 mm)
• Multilingual support

SmsNetAdmin can implement three different mechanisms for the surveillance of network equipment: the first is useful for controlling the device's response on the ethernet, the second allows the working of a specific service to be checked, and the third checks that it is actually the desired service that is responding.

In the first instance, a Ping ICMP request is sent to the appliance's IP address: if a response is obtained the status is considered normal; otherwise the problem is counted. Once the number of non-responses set by the user is reached, the corresponding alarm is sent.

When checking a service, a socket connection with the port in charge of the service itself is attempted; in the same way as the previous case, either a normal response is obtained or the non-response is counted and the corresponding alarm signal activated.

The third mechanism allows an even more thorough check of the chosen service: as in the preceding case, a socket connection is attempted with the port in charge of the service itself; but then the response obtained is analyzed in search of specific identifying features chosen by the user during the configuration phase. In this way not only does the user have the certainty that the service is responding correctly, but also confirmation that it is really the intended service that is responding.

In order to avoid SmsNetAdmin surveillance requests generating too much traffic on the network, the choice of the frequency of checks is left to the user: this can range from one check per minute to one per day, depending on the speed desired in detecting problems.

The device is made up of the following elements:

• Hardware appliance
• GSM transmission antenna
• Configuration CD-ROM
• Manual in Italian/English
• Temperature sensors
