This tool also addresses potential reliability issues that may arise +when `networkd` interferes with tunnels it doesn't manage. Moreover, `wg2nd` can batch-convert `wg-quick` +configurations to `networkd`. + +## Goals of the Project + +1. **Compatibility**: `wg2nd` supports all `wg-quick` configurations except those that involve + `PreUp`, `PostUp`, `PreDown`, and `PostDown` scripts, which are omitted. + +2. **Security**: Private and symmetric keys are stored in keyfiles with restricted access permissions. + `wg2nd` leverages the same formally-verified Curve25519 implementation employed in WireGuard. + All operations involving private keys are executed in constant-time. Additionally, the web port operates + entirely on the client-side. It does not transmit or store any sensitive data. + +3. **Reproducibility**: `wg2nd` generates configurations deterministically with respect to + the input WireGuard configuration. When updates are made to the WireGuard source configurations, + only the corresponding elements in the output will be altered. This ensures that configurations + from a VPN provider can be batch-converted without generating unnecessary files or inducing unexpected + behavioral changes. + + Keyfiles for both private and symmetric keys are named according to the public key of the relevant + interface or peer. These keyfiles are encoded in base32 rather than base64 to avoid issues with the + Unix path separator present in base64 encoding. The public key corresponding to a keyfile can be + obtained using the following command: + + ```bash + echo $KEY | sed -E 's/\.(priv|sym)key//' | base32 -d | base64 + ``` + + This approach effectively ensures that if two interfaces share the same private key, a single shared + keyfile will be generated. The `fwmark` field employs a SipHash of the interface name, enabling the + generation of identical network and netdev files across separate program invocations, while minimizing + the risk of `fwmark` collisions. + +### Compatibility and Limitations + +`wg2nd` is designed for high compatibility but comes with some caveats: + +1. **Dynamic Firewall Installation**: Unlike `wg-quick`, which installs a firewall by default when a default route + is specified, `wg2nd` does not. However, an equivalent firewall can be generated if desired. + +2. **Pre/Post Interface Setup Scripts**: `wg2nd` does not handle `PreUp`, `PostUp`, `PreDown`, and `PostDown` + script snippets, which `wg-quick` does recognize. + +3. **FwMark and Table Handling**: `wg2nd` uses a deterministic method for generating `fwmark` based on the interface + name. This contrasts with `wg-quick`, which dynamically checks availability. This deterministic approach is + necessary because a static value must be chosen for configuration. However, this could result in a birthday + collision if a large number of interfaces are ported.

Bringing up the tunnel - + To start the tunnel, you can use the templated `systemd` service packaged alongside Nebula [^3][^4]. ```bash sudo systemctl start nebula@my_network ``` - + There is also a means by which a Nebula lighthouse can be run by a unprivileged user but further configuration is required [^5]. - + Once both ends of the tunnel have been started, you should be able to ping the lighthouse from the laptop node and vice versa. ```bash ping 192.168.100.1 PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data. 64 bytes from 192.168.100.1: icmp_seq=1 ttl=64 time=5.67 ms ``` - + #### 7. Additional Configuration - + Nebula has built-in default deny firewall. The default configuration file allows network traffic `outbound`. (That is, any node is permitted to initiate a connection.) In order for a node to provide services, the port mapping needs to be added to the `inbound` section. For instance, to permit ssh to the lighthouse: - + ```yaml inbound: - port: 22 proto: tcp host: lighthouse ``` - + Now, an ssh connection should be able to be initiated via Nebula's internal ip: ```bash ssh 192.168.100.1 ``` - + Once you're happy with the setup, you can automatically start Nebula when the laptop / server boots: - + ```bash sudo systemctl enable nebula@my_network ``` - + For more information on usage and configuration, you may want to take a look at `nebula.yml(5)`, `nebula(1)`, and `nebula-cert(1)`. - + Enjoy. ``` * . . * * . . * . * . . * . @@ -136,42 +136,42 @@ Enjoy. . . * . * . * . * * . . * . * . * . * . * . * . . * ``` - + ### Installation Footnotes - + [^1] If you're in need of a technology to provide strong encryption, [LUKS](https://guardianproject.info/archive/luks/) is a popular choice on Linux. [Veracrypt](https://www.veracrypt.fr) is a venerable cross-platform encryption application. Some password managers, like KeePassXC, also allow you to attach files. - + [^2] Effectively, this means all nodes will receive an ip in the form "192.168.y.x". The y part is a value in the range [0, 255] and is specific to the network. (Thus, all nodes should have the same "y" value.) "x" should be a unique ip for each node and be in the range [0, 244]. - + [^3] The launcher I wrote will detect the `my_network.yml` and `my_network.yaml` files. Do not specify the extension when launching the service. The launcher has no way to discriminate between `my_network.yml` and `my_network.yaml` extension so pick a distinct name for each network. - + [^4] If Nebula is misconfigured, the service will fail without warning. You can check the status of the unit with `systemctl status nebula@my_network`. Nebula can also be started within the terminal using `nebula -conifg /etc/nebula/my_network.yml`. - + [^5] The systemd unit that is packaged with Nebula runs the interface as root. This is what I expect most users will want. If the lighthouse doesn't need to be connected to the network, you can `sudo systemd edit nebula@.serivce` and simply change the `User` section to the user you wish to use to launch Nebula. The user will also need read access to the configuration file, key, and cert files. - + Packaging Notes --------------- - + I am going to create a brief summary of the changes made while packaging. I suspect other distros might benefit from some of the work done to package Debian [^6]. - + The Debian package differs from the packaging done on [Arch](https://archlinux.org/packages/community/x86_64/nebula/). There's also a package created for [NixOS](https://github.com/NixOS/nixpkgs/blob/8284fc30c84ea47e63209d1a892aca1dfcd6bdf3/nixos/tests/nebula.nix) but Nix is its own beast. - + ### Templating the Unit File - + If we were to use the unit file provided by the upstream project, it would fail without warning until the user fully setup the service because (1) the path of to Nebula configuration was hard coded as `/etc/nebula/config.yml` and (2) the user needed to change the configuration file in order for Nebula to function. - + To make the relationship between the user configuration and the `systemd` unit clear, the `systemd` unit was templated. This also means that there is a clear and simple way to connect one machine to multiple Nebula networks. To accomplish this and support both `.yml` and `.yaml` extension, the systemd file executes a shell script under `/usr/lib/nebula/bin/nebula-systemd-launcher` passing the "instance variable" as the first argument. This script then identifies the proper configuration and launches Nebula with this configuration. The script was installed user `/usr/lib` so that it would not autocomplete in the user's shell. - + ### Doc and examples - + - Man pages were generated from the nebula help flag to create `nebula(1)` and `nebula-cert(1)`. - `nebula.yml(5)` man page was created to describe the configuration process. It was derived from the comments in the example configuration. - The `config.yml` example configuration was installed under `/usr/share/doc/nebula/examples/` so users could copy it into `/etc/nebula` if they wished to use it as a starting point. - + ### Patching for Go 1.13 - + Debian packages all go dependencies to maintain tight control over the versions used while building go binaries. It also packages `go` itself. Currently, `go 1.16` is not in the debian repos [^7]. The following patch was applied since `net.ErrClosed` is not available in older versions of go. - + ```go --- nebula.orig/sshd/server.go +++ nebula/sshd/server.go diff --git a/posts/packaging-nebula-for-debian/meta.json b/posts/packaging-nebula-for-debian/meta.json index 1f8f362..49ec10e 100644 --- a/posts/packaging-nebula-for-debian/meta.json +++ b/posts/packaging-nebula-for-debian/meta.json @@ -1,4 +1,4 @@ { "name": "Packaging Nebula for Debian", "lastUpdated": "2021-07-19" -}
