Make sure that your port 10002 is not occupied by another program. Well, check that the port is open (although it seems to be open on the local computer)
You should get the open ports in ufw in the list
10000/tcp ALLOW Anywhere 10002/tcp ALLOW Anywhere 10008/tcp ALLOW Anywhere 10008 ALLOW Anywherenetstat -ntulpor
ss -ntulpWhat does the command data show on the remote server? These are commands for ssh connection
The Agent’s log shows which port it is listening on.
1. check that this port is not occupied by other programs
2. Check the firewall to make sure that the port is open.
Ubuntu may have another firewall installed – UFW, or disable it for verification, or configure it to skip port 10002. On one remote VDS server, even with uwf mode configured, it periodically closes until I figured out how to win.service scadaserver6 start
or
systemctl start scadaserver6.service(restart, stop, status)
(scadaagent6, scadacomm6, scadaweb6)the rest is by analogy
Check for uwf on the remote Ubuntu machine. This is another firewall that can block your access
No. .your pem key is used to access the remote server via ssh.
To transfer the project from the Administrator, you need to open TCP port 10002 for ScadaAgent to work. Configure the firewall accordingly.The secret key and passwords in Scada are already internal protection methods so that third-party Scada Administrators cannot connect to your Scada Server and change the data.
The Ubuntu server can be remote with a real IP address (for example, on a VDS server) or connected to your server via VPN.
And there is also an option when the Scada Agent connects via proxy mode. There are many connection options.
