Enable firewall settings: ```bash bashCopyEditsudo ufw default allow outgoing sudo ufw default deny incoming sudo ufw allow ssh/tcp sudo ufw allow ${GALACTICA_PORT}656/tcp sudo ufw enable ``` *** ### **Uninstall Node** If you want to remove the node: ```bash bashCopyEditsudo systemctl stop galacticad sudo systemctl disable galacticad sudo rm -rf /etc/systemd/system/galacticad.service sudo rm $(which galacticad) sudo rm -rf $HOME/.galactica sed -i "/GALACTICA_/d" $HOME/.bash_profile ```
