If you no longer want to use UFW, we have a detailed guide on how to turn off UFW in Ubuntu.Īnd if you have any queries or have any other way to check the firewall status, let me know in the comments.Chris Hoffman is the former Editor-in-Chief of How-To Geek. This guide was about checking the UFW firewall status in Ubuntu command line. In the same manner, you can filter the denied rules using grep -i deny with the ufw status command: sudo ufw status | grep -i deny Wrapping Up So if you want to list only the services that are allowed to pass through the firewall, use the following command: sudo ufw status | grep -i allow To filter output, I will be using the grep command to filter specific results. New profiles: skip: Indicates that the firewall is using default rules.But there are some exceptions (to deny all) which can be found using sudo ufw show raw. Default: deny (incoming), allow (outgoing), deny (routed): It means, on the default setting, all the incoming is denied and outgoing is allowed.UFW supports five logging levels, including off, low, medium, high and full, and you get low level by default. Logging: on indicates that users can read iptables and information related to packet transfers.Seems too complex? let me break it down for you. If the standard output is not enough for you, you can append verbose with this command and you will get a more detailed firewall status: sudo ufw status verbose And if you want to know them, here you have it. There are other ways to filter and get output for your specific use case. Now, the status will be changed to active and will show firewall rules you have defined in the past: Ubuntu comes pre-installed with UFW (uncomplicated firewall) and you can use the given command to check the firewall status: sudo ufw statusĪnd if you get a similar output, it means your firewall is not enabled, which can be enabled using the given command: sudo ufw enable
