General Problems

Cannot access the web interface anymore

If you cannot access the Alert appliance web interface, but still have IP access using ping and ssh, you

likely have a corrupt script (settings) file. Login to the root account using ssh and run the ps command. You

should be able to see many (7) alertd processes running. If not attempt to start alertd as follows:

/bin/alertd

If you get the error message “unsupported platform” you have a corrupt script file. If you have previously

done a backup of the script file you can follow the procedure in the section entitled Restore known good

script backup file to Alert appliance from a remote host. Otherwise without having done a backup use the

following procedure instead:

Place a copy of makemac in the /home directory and run it. Contact Sensorsoft Technical Support for a

copy of makemac. Then be sure to delete makemac, run saveconf and reboot as follows:

# chmod +x /home/makemac

# /home/makemac

# rm –f makemac

# saveconf

# reboot

After the Alert appliance is allowed time to reboot you should be able to access its web interface.

Changes made to Alert appliance’s settings were lost after the appliance was restarted.

If you have modified your Alert appliance’s settings, then the new settings must be saved to the flash

before the appliance is reboot or shutdown, otherwise your changes will be lost. Alert will automatically

update its flash with the latest settings once every 5 minutes. If you need to reboot or shutdown the

appliance immediately after making some changes to the settings, then to ensure that your changes will not

be lost, you must use the Reboot/Shutdown page of the Alert web interface (Refer to the section Appliance

Shutdown and Reboot).

Unable to launch the Sensorsoft Graphing Tool

To run the Sensorsoft Graphing Tool, you need to install the Sun Java Virtual Machine Version 1.4.1 or

higher on your PC. If you are using Internet Explorer, you can check whether Java Virtual Machine

Version 1.4.1 is installed doing the following:

1. Open Internet Explorer

2. In the Tools menus, look for the Sun Java Console option

3. If this option is not there, then you do not have Java Virtual Machine Version 1.4.1 or higher

If the Java Virtual Machine is installed and you are still unable to launch the Sensorsoft Graphing Tool, try

logging out of the Alert web interface, and then in a new browser window, login again and click on the

Graph Data Files link.
