wg-meshconf
wg-meshconf is a tool that will help you to generate peer configuration files for WireGuard mesh networks. You can easily and quickly create WireGuard mesh networks using this tool.
Installation (PyPI)
This is the recommended way to install wg-meshconf for regular users. This installation method installs the newest release version of wg-meshconf and all of the required dependencies from PyPI.
# installing the program with pip
# note that Pip for Python3 might be named "pip3" on some systems
pip install --user -U wg-meshconf
# running the program
wg-meshconf showpeers
You may now run the program by executing the wg-meshconf
command.
Installation (GitHub)
Alternatively, if you would like to install the program directly from source code, you can follow the steps below. If you would like to install directly from the Git repository:
# install the HEAD (latest) commit
pip install 'wg-meshconf@git+https://github.com/k4yt3x/wg-meshconf.git'
# install from a specific tag or commit
pip install 'wg-meshconf@git+https://github.com/k4yt3x/wg-meshconf.git@2.5.1'
pip install 'wg-meshconf@git+https://github.com/k4yt3x/wg-meshconf.git@aa16407'
You can also clone it and install it locally.
# cloning the repository with git
git clone https://github.com/k4yt3x/wg-meshconf.git
# enter the directory
cd wg-meshconf
# install the program with Pip
# Pip and PDM will take care of dependency installation
pip install -U .
Learn by an Example
Usages are dull and boring. Let's see a real-life example of how this tool can be used. This section will demonstrate how to create a simple mesh network with four nodes using wg-meshconf.
For this example, suppose you have four servers as shown below. These servers can reach each other via the Endpoint
address. For instance, server tokyo1
can ping server shanghai1
with the address shanghai1.com
.
Step 1: Add Basic Peer Information
You will first need to add the peers' information into the database. There are two ways to do it: via Excel and via the command line interface.
Method A: With Excel
wg-meshconf has changed its database format from JSON to CSV and added the init
command since version 2.4.0. This means that it is now possible for users to directly edit the database file with Excel or other CSV-compatible editors to create/read/update/delete peer information.
(P.S. I thought about making a fancy GUI for wg-meshconf like the other tools, but then I thought, why do it the complex way when you can simply "borrow" Excel's GUI?)
Run the following command to initialize a new database file. By default, the database file is named database.csv
. You can also specify the file's name via -d
.
wg-meshconf init
Open the database CSV file with an editor like Excel or LibreOffice Calc. You should see the following column headers.
You can then fill in the peers' information. You will need to fill in at least the peers' Name
, Address
, and Endpoint
values. These values cannot be automatically generated.
Once you're done, save the file and execute the init
command again to automatically generate the rest of the needed information such as peer private keys.
wg-meshconf init
If you check the file again, you'll see the necessary fields getting automatically filed in.
Method B: With Terminal
If, for some reason, you don't want to edit the database file directly, you can also use this tool purely through its command line interface.
First we need to add all peers in the mesh network into the database. The basic syntax for adding new peers is:
wg-meshconf addpeer NAME --address IP_ADDRESS --address IP_ADDRESS_2 --endpoint ENDPOINT
- New private key will be generated automatically if unspecified
- ListenPort defaults to 51820 per WireGuard standard
- All other values are left empty by default
There are more options which you can specify. Use the command wg-meshconf addpeer -h
for more details.
After adding all the peers into the database, you can verify that they have all been added correctly via the wg-meshconf showpeers
command. The simplify
switch here omits all columns with only None
s.
Step 2: Export Configuration Files
Use the genconfig
command to generate configuration files for all peers. You may also export configurations for only one peer by specifying the peer's name.
The configuration files will be named after the peers' names. By default, all configuration files are exported into a subdirectory named output
. You can change this by specifying output directory using the -o
or the --output
option.
Step 3: Copy Configuration Files to Peers
Copy each of the configuration files to the corresponding peers.
Step 4: Start WireGuard Services
Start up the WireGuard interfaces using the wg-quick
command. It is also possible to control WireGuard interfaces via WireGuard's wg-quick@
systemd service. WireGuard status can be verified via the wg
command after WireGuard interfaces are set up.
Step 5: Verify Connectivity
Verify that all endpoints have been configured properly and can connect to each other.
Done. Now a mesh network has been created between the four servers.
Updating Peer Information
If you would like to update a peer's information, use the updatepeer
command. The syntax of updatepeer
is the same as that of the addpeer
command. Instead of adding a new peer, this command overwrites values in existing entries.
In the example below, suppose you would like to update tokyo1
's endpoint address and change it to tokyo321.com
. Use the updatepeer
command and specify the new endpoint to be tokyo321.com
. This will overwrite tokyo1
's existing Endpoint
value.
Show Peer Information
The showpeers
command prints all peers' information by default.
Now that's a lot of info and a lot of unnecessary columns which only have None
s. Therefore, I added the -s
/--simplify
command which omits those useless columns.
You may also query information about a specific peer.
Plaintext mode has a similar usage. It's just a bit harder to read, at least for me.
Deleting Peers
Use the delpeer
command to delete peers. The syntax is delpeer PEER_NAME
.
This example below shows how to delete the peer tokyo1
from the database.
Database Files
Unlike 1.x.x versions of wg-meshconf, version 2.0.0 does not require the user to save or load profiles. Instead, all add peer, update peer and delete peer operations are file operations. The changes will be saved to the database file immediately. The database file to use can be specified via the -d
or the --database
option. If no database file is specified, database.csv
will be used.
Database files are essentially just CSV files (it was JSON before version 2.4.0). Below is an example.
