Fabchain testnet node not syncing

Trying the latest commit (2b3e5b0) and just running make run starts the node but it's not syncing.

Starting geth for chainID: fabt (1717658228)

It just sits there. There seems to be not connecting to any node:

Is the testnet network working right now? The website seems to be down (https://fabchain.net/).

Make block explorer url compatible with metamask

Metamask links to an executed transaction once done using a url that is slightly incompatible with our explorer:

/tx/ -> /#/transaction/

the /tx/ part of the address should be translated to /#/transaction/

Monitor uptime of nodes

Can be done using github actions: https://github.com/upptime/upptime

Zenroom and other tools are required for some operations

Example:

$ make genesis-create
/bin/sh: 1: zenroom: not found
/bin/sh: 1: jq: not found

###########################
now RUN: make genesis-init
###########################

Those tools are probably inside the docker image so instead of trying to run directly on the host perhaps a solution is to run it inside a docker instance mounting the proper paths.

ETH metrics monitor

client https://eth.wiki/en/concepts/network-status

Naming of eth and ERC20: "FAB" -> "FAB-GAS" and "ERC20" -> "FAB"

We are introducing an ERC20 (token) used to trade goods and services, next to the eth (coin, currently named "FAB"), needed to pay transactions.
This ERC20 will be initially (maybe forever) not exchangable with the eth. In order to keep things simple and stick to Ethereum standard name, we should use a naming policy like:

• ERC20 = "FAB"
• Eth = "FAB-GAS"

Currently this requires only a change in this line

Create a "zero-configuration" link to FABT for metamask

Somewhere someone mentioned that is possible to produce a simple link that when clicked configures automatically the network for metamask. Any info?

Fail2ban rules to protect against common attacks on API servers

Analyse the logs we sampled from testnet and identify common attacks to make a new fail2ban rule that prevents them to flood servers.

Cannot start under Microsoft/WSL

According to the README this application is compatible with WSL.

This application is made to work on Apple/OSX, Microsoft/WSL or GNU/Linux desktop systems.

But currently running make run on a Windows 10 + WSL2 + Docker 4.5.1 refuses to start the geth daemon inside the container.

Fatal: Error starting protocol stack: listen unix /home/geth/.ethereum/geth.ipc: bind: operation not supported

Bug, documentation issue or am I doing something wrong?

Logrotate for geth.log

The file /home/app/dyneth/data/geth.log (fixed path) should be put under logrotation

Docker image not found when running `make run`

Running make run tries to pull a docker image using a tag built from a hash and a version string. They appear to be out of sync currently as the version says 0.7.0 and the hash 516fe1f1f82d1114ffb03fd9cd8d4a14100b64de which points to an unpublished version.

Unable to find image 'dyne/dyneth:0.7.0-516fe1f1f82d1114ffb03fd9cd8d4a14100b64de' locally
docker: Error response from daemon: manifest for dyne/dyneth:0.7.0-516fe1f1f82d1114ffb03fd9cd8d4a14100b64de not found: manifest unknown: manifest unknown.

Reverting the version string to 0.6.0 allows the script to run.
