Chapter 3. Using the System
SMS messages. By default, the Compact Flash card is used. The PIN code query of the SIM card
at power-up must be disabled.
WRAP SMS Gateway Server is disabled by default. To enable it, use the setup application’s
WWW interface, as described in section Section 2.4. Enabling is done at Setup −→ Applications
−→ Default bootup applications −→ smsgw.
WRAP SMS Gateway Server can be configured to use a modem connected to the user serial
port with the setup application or its WWW interface by changing the setting at Setup −→
Applications −→ SMS gateway settings −→ Modem device to /dev/ttyAT1 from the default
/dev/ttyS0.
Note: If you are using the user serial port, ensure you have Bluetooth Serial Port Profile disabled, as
they share the same physical user serial port.
Note: To use Nokia terminals, the device must be connected to the user serial port when the server
starts up. Also, the terminal must be configured to operate in RS-232/AT command. Nokia terminals
are configured with the N20 or N30 Configurator application.
For further information on using smsgw, see the makesms example in
Section 6.3.1.
3.5.4. User Level Watchdog
WRAP User Level Watchdog daemon listens on UDP port 4266 for "id timeout" messages. "id"
is an ASCII string, without spaces. If "timeout" equals to 0 (zero), the "id" is removed from the
list of processes to wait. If "timeout" is greater than 0 (zero), the "id" is added or updated.
When there is no message for "id" received within the "timeout" seconds, the user level watch-
dog dies and the kernel watchdog reboots Access Server.
The watchdog command can be used to send messages to the watchdog daemon. This is done
through command watchdog id timeout. For example, watchdog test 5.
3.5.5. Remote Management
Access Server contains simple tools that provide means for full and secure remote management
of the device.
The basic remote management can be performed using the WWW Setup interface, SSH com-
mand line access, and SCP and SFTP file transfer protocols.
In addition to those, Access Server contains WRAP Remote Management System for transferring
management packets over different media to Access Server and automatically sending response
packets back.
The management packets (
*
.wpk) are automatically processed when they are transferred to the
autoinstall directory in Access Server (/tmp/obex by default, but configurable with the setup
application or WWW interface at Setup −→ Applications −→ wpkgd settings). The easiest way
to transfer a management packet to this directory is to upload it from WWW Setup at Setup −→
Advanced settings −→ Upload a software update.
