Installation

This is an example of installation on an amd64 Linux system with systemd.

Download the binary and the systemd service file:

wget https://git.rznet.fr/tchivert/portus/releases/download/latest/portus-linux-amd64 -O /usr/local/bin/portus
chmod +x /usr/local/bin/portus

If you want to use the systemd service file, download it:

wget https://git.rznet.fr/tchivert/portus/raw/branch/main/systemd/portus.service -O /etc/systemd/system/portus.service

Or configure a cron job to use portus without daemon mode:

crontab -e
0 */6 * * * /usr/local/bin/portus -i /etc/portus/ips.txt -l /var/log/portus -p 1-10000

Create the logs and configuration directories:

mkdir /var/log/portus
mkdir /etc/portus

Add your IPs list in the ips.txt file:

vim /etc/portus/ips.txt

Edit the systemd service if needed, then enable and start it:

vim /etc/systemd/system/portus.service
systemctl enable --now portus

Build

go build -o portus
