Zeroshell is available for x86/x86-64 platforms and ARM based devices such as Raspberry Pi. Zeroshell is a Linux based distribution dedicated to the implementation of Router and Firewall Appliances completely administrable via web interface. The domain will be decommissioned or sold on September 30, 2021. I thank everyone who believed and contributed in various ways to improving the project. Any security updates will be guaranteed until September 30, 2021. Zeroshell was born in June 2006 and has exceeded 200.000 installations in the world. I hope to be doing some more work with BIRD, but that's about as far into it I will be going right now.The project has now reached the end of life.

You can verify your BGP session establishment from here:Īs you can see here, we have a full-table BGP session to our neighbor, as configured earlier, and we can look through our BIRD RIB accordingly: You can enter the CLI client by running birdc as root:įrom here, the interface supports tab-completion, classic "?" queries, and a "show" command style language:Īlternatively, you can prepend any BIRD commands with "birdc" and run them straight from bash, which is needed for scripting Once you are happy with your configuration file, save the file and restart / enable the service:īIRD comes with a very Cisco-esque terminal interface, which is extremely easy to pick up. Here is an example BGP neighbor configuration: Like everything else so far, BGP is also configured in /etc/bird/nf. Add any critical routes as follows (where is your network interface device):Īnd to make it persistent, add to /etc/sysconfig/network-scripts/: If you are exporting BGP routes back into the kernel's RIB, depending on your use-case you may also want to solidify your servers routing to ensure that BGP routes don't take preference. # kernel table 5 # Kernel table to synchronize with (default: main)Įnsure that the kernel export is set to none if you want to ensure that BIRD will not have any effect on the server's routing decisions Scan time 20 # Scan kernel routing table every 20 seconds Persist # Don't remove routes on bird shutdown # learn # Learn all alien routes from the kernel Some typical changes you may wish to make could be: The file is very well-commented, and all protocol configurations are commented out by default, to be used as references. Once installed, you will want to make some standard changes to the default configuration file ( /etc/bird/nf). Gpgkey=file:///etc/pki/rpm-gpg/Ĭurl -o /etc/pki/rpm-gpg/ Sudo add-apt-repository ppa:cz.nic-labs/birdġ.Ědd the YUM repository by creating the file /etc//bird.repo While there a number of BGP implementations available to Linux users (an honorable mention to ExaBGP and Quagga), BIRD is full-featured, well-documented, and one of the most popular daemons available, and so I will be sticking with it for the time being. In this post I will be quickly running through the basic setup and configuration of BIRD, an open-source routing protocol daemon for Unix-like systems with an amusingly recursive acronym ( BIRD Internet Routing Daemon).
