Network Example

The following diagram shows how the system could be configured on an internal network:

The server and the nodes are on the same internal network, so all of them can be seen by the server (172.17.1.5).

The server and nodes have an user named dtc, in charge of executing the command.

The configuration command that should be run in this case is the following:

    go run github.com/niclabs/dtcconfig rsa \
    -t 3 \
    -n 172.17.1.11:2030,172.17.1.12:2030,172.17.1.13:2030,172.17.1.14:2030,172.17.1.15:2030 \
    -H 172.17.1.5 \
    -d /home/dtc/dtc.sqlite3
    -l /home/dtc/dtc.log

then the files should be copied on each node:

• Copy node_1/config.yaml to /etc/dtcnode/config.yaml in machine 172.17.1.11
• Copy node_2/config.yaml to /etc/dtcnode/config.yaml in machine 172.17.1.12
• Copy node_3/config.yaml to /etc/dtcnode/config.yaml in machine 172.17.1.13
• Copy node_4/config.yaml to /etc/dtcnode/config.yaml in machine 172.17.1.14
• Copy node_5/config.yaml to /etc/dtcnode/config.yaml in machine 172.17.1.15

and the program dtcnode should be executed on each machine. You can also set it as a systemd service if you want.
