babelweb 2
babelweb 2 is a monitoring tool for Babel. It shows with a web interface the current neighbors, the current routes and a graphical overview of the babel network.
Installation
First you have to download go. You can do this on Debian for example with the following command:
sudo apt install golang
After that you have to clone the current git repo and compile the program:
git clone https://github.com/Vivena/babelweb2
cd babelweb2
go build
Now you have an executable program babelweb2.
By default, the web interface runs on port 8080. You can also specify a different endpoint with the -http parameter.
babelweb2 uses the local configuration interface of babeld. This must have been activated beforehand. babeld assumes that this is active on [::1]:33123. Alternatively, you can specify the endpoint with the -node= flag.
Install as Systemd Unit
In order to install babelweb2 as a systemd unit, we must first install the necessary files into the system. For this we can execute the following commands in the babelweb2 git directory:
sudo cp babelweb2 /usr/local/bin
sudo mkdir -p /usr/share/babelweb2/
sudo cp -r ./static/ /usr/share/babelweb2/
After that we create the unit file /etc/systemd/system/babelweb2.service:
[Unit]
Description=Yet Another Monitoring Tool for the Babel routing daemon
Documentation=https://github.com/Vivena/babelweb2
[Service]
LimitNOFILE=1048576
LimitNPROC=512
User=nobody
EnvironmentFile=/etc/default/babelweb2
ExecStart=/usr/local/bin/babelweb2 -http $PORT -static $STATIC_DIR
ExecReload=/bin/kill -SIGUSR1 $MAINPID
Restart=on-failure
[Install]
WantedBy=multi-user.target
After that you can reload the units:
systemctl daemon-reload
For babelweb2 to work, we still need to specify the arguments. For this we can create an environment file /etc/default/babelweb2:
PORT=:<port>
STATIC_DIR=/usr/share/babelweb2/static/
Here we replace <port> with the port on which the Babelweb2 interface should be available. The default is 8080, but you can also use 33124, for example.
