Deviota Field is a Proxy for your IRI, that sends regular statistics to the Field server (http://field.deviota.com) and accepts jobs from the server's load balancer (optional).
It is extremely tiny layer/app that does not require much resources. The idea behind Field is explained here:

- Building Locally
These instructions will get you a copy of the project up and running on your local machine.
It is expected that you have already installed Java, downloaded the IRI jar file and know how to start it. The local IRI instance must have api enabled and accepting local connections.
Field is running on Node.js You will have to install node (at least version LTS 8.9.4) and npm (node package manager) on your system. Alternatively to npm you can (and should) use yarn package manager.
If you are trying to run a Field node at home, you may need to open some ports (port forwarding) in your NAT Router, apart of the ports for your IRI:
- TCP 21310
Please refer to your Router's manual on how to do that.
Furthermore, please be aware that apart of firewall and port-forwarding in router, your Internet provider may also be an issue. Some providers (like Vodafone in Germany) do not have enough IPv4 addresses for homes and thus use something called "IPv4 over DS Lite". In those cases the traffic will not come through over the ports mentioned above. Unfortunately, there is no quick fix for this issue (maybe changing providers). There is some hope with the upcoming PCP-protocol, this will not happen this year (2018) for most providers, though.
WARNING FOR IMAGE-BASED LINUX INSTALLATIONS
Field relies on a unique machine identification. Image-based/VPS installations usually have the same id. If you run it, your field might be blacklisted or wrongly listed on the field server. To change the ID, do the following:
# 1. Remove the existing machine ID file: sudo rm /var/lib/dbus/machine-id # 2. Generate a new machine id: sudo dbus-uuidgen --ensure # 3. Reboot to apply the new machine ID system-wide: sudo shutdown -r now
WARNING FOR UBUNTU
Ubuntu 16.04 apt comes with an outdated Node version (4.X). You need to install the latest version separately:
Globally install Field
npm install -g @semkodev/field.cli
And run it
field --pow --address SOZAIPJMQUBOFCTDTJJDXCZEKNIYZGIGVDLFMH9FFBAYK9SWGTBCWVUTFHXDOUESZAXRJJCJESJPIEQCCKBUTVQPOW
--pow option allows the Field server to pass "attachToTangle" jobs to your IRI.
--address option you can specify an IOTA address for donations.
Below is the list of all possible options.
To upgrade your Field to version X.X.X, simply run:
npm install -g @email@example.com
Please check where npm installs your global packages! It happens very often that the first installed binary
is put into
/usr/local/bin and the updated into
field --version after the upgrade
to make sure you are using the most recent one. Update your scripts and/or services to point to the right binary!
Running as a service
You can use the node process manager to run Field as a service. Just do the following:
# Install the process manager: npm install pm2 -g # Make pm2 start at startup: pm2 startup # Start the Field as service # If you created a field config somewhere on your system, provide the path to the config: pm2 start field -- --config /path/to/field-config.ini # Otherwise you can just do: pm2 start field # Save current processes runing with pm2 to startup on boot: pm2 save # Get Field logs: pm2 monit # or pm2 log
Provided you have docker installed, Field can be started as follows:
docker run <docker opts> semkodev/field.cli <field command line opts>
If you are a developer you may want to build the project locally and play around with the sources. Otherwise, ignore this section. Make sure you have yarn package manager installed. Checkout the project:
git clone firstname.lastname@example.org:semkodev/field.cli.git cd field.cli
Run tests and make binaries:
Try to run Field:
node ./dist/field.js --pow -y
You are free to either use command line options or an
.ini file to configure Field. If you use a config
file, it has precedence and all command line options are ignored.
To use a configuration file, run Field with
field --config ./config.ini # Alternatively, set an environment variable: FIELD_CONFIG= ./config.ini field
You can provide one or more of the following options in your ini file. Example:
[field] name = MyField ; Optional, which IP to bind the node on bindAddress = 0.0.0.0 port = 21310 ; If you want Field to generate a custom id, instead of using machine-id. ; This is the safest and favored way: customFieldId = true ; You can choose which Field(s) to connect to: fieldHostname = field.deviota.com:80 ; It can be several Fields. Just repeat: ; fieldHostname = field.deviota.com:80 ; fieldHostname = another.field.com:8080 ; fieldHostname = mytest.field.com:5000 ; IRI connection details: IRIPort = 14265 IRIHostname = localhost address = SOZAIPJMQUBOFCTDTJJDXCZEKNIYZGIGVDLFMH9FFBAYK9SWGTBCWVUTFHXDOUESZAXRJJCJESJPIEQCCKBUTVQPOW ; Alternatively to address, you can provide a (NEW) seed ; In this case, the Field client will be generating new, unused addresses dynamically. ; seed = XYZ ; What jobs your node should be able to accept: ; both true - only attachToTangle jobs accepted ; disableIRI false - all jobs accepted ; pow false - no jobs accepted ; both false - all jobs except attachToTangle accepted pow = true disableIRI = false
Command line options
Command line options are named the same as INI options. Some have additional short versions.
|--name||Name your node. This identifier will appear on the deviota Field Dashboard||deviota Field|
|--address, -a||Optional IOTA address for donations.|
|--seed, -b||Optional. If no donation address is provided, you can provide a seed. In that case the field client will generate new, unused addresses dynamically. WARNING! Please do not use your usual, main seed. Generate a new one for this occasion. It is easy and adds up to everyone's security.|
|--config, -c||Path to Field configuration file.|
|--disableIRI, -d||Do not allow jobs to be passed from the Field load balancer. Just send the statistics about my node.||false|
|--fieldHostname, -f||Field Server hostname (including port) or a space-separated list of multiple Field Server hostnames.||field.deviota.com:80|
|--iriHostname, -h||Hostname where your IRI instance is running.||localhost|
|--iriPort, -i||API port of your IRI instance.||14265|
|--port, -p||Field port to be used||21310|
|--silent, -s||Do not print log messages||false|
|--pow, -w||Allow attachToTangle jobs to be passed from the Field server load balancer. When disableIRI and pow are true, only PoW work will be passed to IRI.||false|
|--customFieldId, -y||If you want Field to generate a custom id, instead of using machine-id. This is required for VPS and servers created from an image, which often have the same machine ID.||false|
Run PoW jobs only
If you disableIRI and set "pow" to true, your node will only pass attachToTangle jobs t IRI. The jobs will be sent, even if your IRI is not synchronized, since proof-of-work does not require a synchronized node.
# Disable IRI Jobs disableIRI = true # Except attachToTangle proof-of-work pow = true
Donations always welcome:
Donate to the Nodes
We are currently working to add automatic donations to participating nodes based on the work done. This feature is still in progress, however you can already tip the nodes. Just go to http://field.deviota.com select a node, copy its donation address and show it some love!
