Is the Linux firewall disabled?
It depends on your specific configuration. In some cases, the Linux firewall may be default set to off, while in other cases, it may be on. To determine the status of the Linux firewall, execute one of the following commands:
- Check the firewall status using the iptables command.
sudo iptables -L
If the command output is empty or displays “ACCEPT”, it means the firewall is turned off.
- Check the firewall status using the firewalld command (for systems using firewalld).
sudo firewall-cmd --state
If the command output is “running”, it means the firewall is enabled.
If the firewall is turned off and you want to enable it, activate a firewall tool that is suitable for your system and configure the appropriate rules to protect your system.
