When an application wants to connect to the internet – or accept a connection from outside – a clear question appears: which program, which destination, which port. You choose: allow or block, just now, for an hour, until the program ends, or for good. Your answers become rules you can change at any time. * One question at a time, even when many programs knock at once * Every connection, in and out, neatly grouped by program * Turn a rule from allow to block – and back – with one click * Everything that was blocked – and why * Live traffic of your computer at the top of the window * One switch turns the whole firewall off and on Available in 83 languages. The firewall needs three permissions. Paste this one line into a terminal and press Enter: sudo sh -c 'for i in firewall-control network-observe system-observe; do snap connect jsbudbrainfirewall:$i; done; snap restart jsbudbrainfirewall' Keywords: firewall, application firewall, outbound firewall, network security, block connections, allow connections, internet access, privacy, network monitor Also available as .deb, RPM and for Arch at www.budbrain.de ### Package name * jsbudbrainfirewall --- ### License * Proprietary --- ### Last updated * Today - latest/stable --- ### Websites * [www.budbrain.de](https://www.budbrain.de/budbrain-software/ "https://www.budbrain.de/budbrain-software/") --- ### Contact * [jsbudbrainfirewall@budbrain.de](mailto:jsbudbrainfirewall@budbrain.de "mailto:jsbudbrainfirewall@budbrain.de") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/jsbudbrainfirewall/ubuntu#report-snap-modal) --- [See more information about jsbudbrainfirewall ›](https://snapcraft.io/jsbudbrainfirewall) ## Enable snaps on Ubuntu and install jsBudbrainFirewall Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install jsBudbrainFirewall To install jsBudbrainFirewall, simply use the following command: ``` sudo snap install jsbudbrainfirewall ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
