use snap sync in the config, if full needed - change this line

SyncMode = "snap"

to

SyncMode = "full"

start bash

To show full detail help info of all flags, type geth help or geth -h

• run.sh

#!/usr/bin/env bash
/data/hepton/geth-linux-amd64 \
--config /data/hepton/config.toml  \
--logpath /data/hepton/logs \
--verbosity 3  >> /data/hepton/logs/systemd_chain_console.out 2>&1

if you need to use it as archive node, add:

--syncmode full \
--gcmode archive \

so:

#!/usr/bin/env bash
/data/hepton/geth-linux-amd64 \
--config /data/hepton/config.toml  \
--logpath /data/hepton/logs \
--syncmode full \
--gcmode archive \
--verbosity 3  >> /data/hepton/logs/systemd_chain_console.out 2>&1

If no network flags were provided, the node will connect the hepton-mainnet by default. If you want to connect to hepton-testnet, add:

--testnet
