Specific version:

VERSION=v1.0.0 curl -sSL https://raw.githubusercontent.com/m1ngsama/TNT/main/install.sh | sh

Manual Install

Download binary for your platform from releases:

# Linux AMD64
wget https://github.com/m1ngsama/TNT/releases/latest/download/tnt-linux-amd64
chmod +x tnt-linux-amd64
sudo mv tnt-linux-amd64 /usr/local/bin/tnt

wget https://github.com/m1ngsama/TNT/releases/latest/download/tnt-darwin-arm64
chmod +x tnt-darwin-arm64
sudo mv tnt-darwin-arm64 /usr/local/bin/tnt

systemd Service

Create user and directory:

sudo useradd -r -s /bin/false tnt

Install service file:

sudo cp tnt.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable tnt
sudo systemctl start tnt

Optional runtime overrides:

sudo tee /etc/default/tnt >/dev/null <<'EOF'
PORT=2222
TNT_BIND_ADDR=0.0.0.0
TNT_STATE_DIR=/var/lib/tnt
TNT_MAX_CONNECTIONS=200
TNT_MAX_CONN_PER_IP=30
TNT_RATE_LIMIT=1
TNT_SSH_LOG_LEVEL=0
TNT_PUBLIC_HOST=chat.m1ng.space
EOF

sudo systemctl restart tnt

Check status:

sudo systemctl status tnt
sudo journalctl -u tnt -f

Configuration

Environment variables:

# Change port
sudo systemctl edit tnt
# Add:
[Service]
Environment="PORT=3333"

sudo systemctl restart tnt

The service uses StateDirectory=tnt, so systemd creates /var/lib/tnt automatically. Use TNT_STATE_DIR or tnt -d DIR when running outside systemd to avoid depending on the current working directory.

Firewall

sudo firewall-cmd --permanent --add-port=2222/tcp
sudo firewall-cmd --reload
