If changes are made to scadagw.cfg on one SCADA gateway it
needs to be edited on all SCADA gateways in the network, and a
backup of the settings should be taken after any edits.
The release notes for a scadagw version should be checked for any
changes to the settings included in this file.
1. Connect to the SCADA gateway using SSH (Section 4.1). Ensure
you are logged in as the taitnet user (not root).
2. Save a backup of the scadagw.cfg file using the command:
cp /home/taitnet/scadagw/scadagw.cfg /home/
taitnet/scadagw/scadagw.cfg.backup
3. Make a copy of the scadagw.cfg file editing using the command:
cp /home/taitnet/scadagw/scadagw.cfg /home/
taitnet/scadagw/scadagw.cfg.edit
4. Edit the scadagw.cfg file using the command:
nano /home/taitnet/scadagw/scadagw.cfg.edit
This brings up the nano text editor. The cursor can be moved using
the keyboard arrow keys. Text can be inserted and deleted using the
keyboard.
5. Take care to not modify any lines of the file you do not intend to
modify.
6. Settings in the file follow the format <key>: <value>.
7. Comments can be written in the file by putting a # character at the
beginning of the line.
8. To exit the editor without saving use Ctrl+X and press n when
prompted to save.
9. To save the changes use Ctrl+O to save and Ctrl+X to exit the editor.
10. If you are happy with the edits then copy the edits over the master
file using the command:
mv /home/taitnet/scadagw/scadagw.cfg.edit /home/
taitnet/scadagw/scadagw.cfg
11. The SCADA gateway service must be restarted to apply the changes
(
Section 4.6).
12. Take a backup of the edited scadagw.cfg file.
The following parameters are ones that may be modified by the customer
