gmt_dos-clients_scope
gmt_dos-clients_scope
is a client/server graphical display implementation for gmt_dos-actors models.
The communication between the client and the server is secured with a signed certificate
that must be provided by the server.
The authentification certificate is generated by calling crypto
into a terminal on the server.
crypto
is installed with
cargo install --bin crypto gmt_dos-clients_transceiver
The generated certificate gmt_dos-clients_transceiver_cert.der
must be uploaded onto the client machine.
gmt_dos-clients_scope
has 2 features: server
and client
.
The server
feature need to be enabled only on the server applications:
cargo add gmt_dos-clients_scope --features=server
and the client
feature only on the machine displaying the scopes:
cargo add gmt_dos-clients_scope --features=client
AWS EC2 Instance Setup
To stream data to a local scope from an AWS EC2 instance, a new inbound rule needs to be added to the Security Group of the instance, a rule with the UDP protocol, a port or a port range, and any IPv4 source selected, for example:
AWS EC2 instances have 2 IPs, a local or private IP and a public IP.
The IPs can be found from the AWS dashboard or from a terminal connected to the instance by running: ec2metadata | grep ip
.
To check that the new rule of the Security Group is set up properly, on the instance listen to one of the UDP port with
netcat -luv 5001
and on the local machine send a message to the instance UDP port with
echo "hello world" | netcat -uv <instance-public-ip> 5001
On the instance, the following should be written at the prompt:
Connection from <your-machine-ip> <your-machine-port> received!
hello world
The instance local IP is assigned to the scope server whereas the instance public IP is assigned to the scope client.
