To run this sample:
- Launch either the
samples/simple-server, or3rd-party/node-opcua-server. Both servers expose the same variables. - a)
cargo run, or b)cargo run -- --subscribe
Without an argument the client will connect to the server, read and print out the current values of v1, v2, v3 v4 and terminate.
With the --subscribe argument the client will connect to the server, create a subscription and monitor changes on v1,
v2, v3, v4 and continue to print out changes without terminating.
At startup the client will check for, and if necessary create a pki/ folder. It will create a certificate
for itself if one does not exist already. When the client connects to a server over a signed or signed/encrypted
connection it will present this server. Servers can reject certs they do not recognise so you may have to
manually add trust for your client before it will work - this really depends on how your server functions.
The client's client.conf is set up to automatically trust the server's certificate so you do not need to do anything
special client side.
