Assuming that the server certificate file to be uploaded is called server-
scadagw1.crt
, and the associated private key file is called server-
scadagw1.key

there will not be a key file), to load a new certificate and associated private
key file:
1. Select Files > Backups on the SCADA gateway WebUI and click
Upload.
2. Click Choose File.
3. Select the server-scadagw1.crt file to upload and click Open.
4. An upload progress window will be displayed. Once the upload is
complete the file will be listed on the Files > Firmware page.
5. To upload the private key (if required), perform Steps 1 to 4 for the
server-scadagw1.key file.
6. Connect to the SCADA gateway via ssh as the taitnet user (see
Section 4.1).
7. Move the certificate file to the correct place using the following
command:
mv /home/taitnet/scadagw/backups/server-
scadagw1.crt /home/taitnet/scadagw/ssl/server.crt
8. Press y when prompted to overwrite the existing file.
9. Move the private key file (if required) to the correct place using the
following command:
mv /home/taitnet/scadagw/backups/server-
scadagw1.key /home/taitnet/scadagw/ssl/server.key
10. Press y when prompted to overwrite the existing file.
11. Restart the SCADA gateway (see Section 4.6).
4.5 Changing the ‘root’ and ‘taitnet’ Passwords
Tait networks are deployed with default weak passwords and it is the
responsibility of the client to change them to strong passwords.
To change the password of a user, login as that user and enter:
passwd
You will be prompted to re-enter your current password. Next you will be
asked to enter the new password that you wish to use. You will then be
asked to confirm the new password.
