Almost every tutorial for setting up a witness node mention that it is important to ping all seed-nodes and add the fastest nodes to the config.ini file. For improving this process, I wrote a small python script, which:
- measure ping times
- sort the seed nodes
- exclude slow nodes
- creates entries for the
config.inifile
You can find the script here https://github.com/holgern/steem-witness-tools. Steps for running the script on your witness server:
- install python3 and pip3
- install ping3 by
pip3 install ping3 --user - cloning my git:
git clone https://github.com/holgern/steem-witness-tools.git - You may copy the newest seednodes.txt from https://github.com/steemit/steem/blob/master/doc/seednodes.txt
- Enter the sort_seed_nodes directory (
cd sort_seed_nodes) - Run the script by
sudo python3 ping_seed_nodes.pyas root - Copy the result directly to your
config.ini
Script arguments
It is possible to modify the maximum allowed ping time in milliseconds. Default is 100 ms, which means that all seed nodes are included with a ping time better than 100 ms. In the following example, the maximum time is set 50 milliseconds:
sudo python3 ping_seed_nodes.py --maxdelay 50
It also possible to use a different seed-node.txt file as source. It must follow the same structure as the seed-node.txt file.
seed-east.steemit.com:2001 # steemit
seed-url:port # owner
The inputparameter allows to use different files as source:
sudo python3 ping_seed_nodes.py --input my-seed-nodes.txt
Result
The results are also stored in sorted_seednodes_6_6_2018.txt, the name is adapted to the date.
