# Debian Packaging for socktop
This document describes how to build and use Debian packages for socktop and socktop_agent.
## Prerequisites
Install `cargo-deb`:
```bash
cargo install cargo-deb
```
## Building Packages Locally
### Build for your current architecture (x86_64)
```bash
# Build socktop TUI client
cargo deb --package socktop
# Build socktop_agent daemon
cargo deb --package socktop_agent
```
The `.deb` files will be created in `target/debian/`.
### Cross-compile for ARM64 (Raspberry Pi, etc.)
First, install cross-compilation tools:
```bash
sudo apt-get update
sudo apt-get install gcc-aarch64-linux-gnu libc6-dev-arm64-cross
```
Add the ARM64 target:
```bash
rustup target add aarch64-unknown-linux-gnu
```
Configure the linker by creating `.cargo/config.toml`:
```toml
[target.aarch64-unknown-linux-gnu]
linker = "aarch64-linux-gnu-gcc"
```
Build the packages:
```bash
# Build for ARM64
cargo deb --package socktop --target aarch64-unknown-linux-gnu
cargo deb --package socktop_agent --target aarch64-unknown-linux-gnu
```
## Installing Packages
### Install socktop TUI client
```bash
sudo dpkg -i socktop_*.deb
```
### Install socktop_agent daemon
```bash
sudo dpkg -i socktop_agent_*.deb
```
The agent package will:
- Create a `socktop` system user and group
- Install the binary to `/usr/bin/socktop_agent`
- Install a systemd service file (disabled by default)
- Create `/var/lib/socktop` for state files
### Enable and start the agent service
```bash
# Enable to start on boot
sudo systemctl enable socktop-agent
# Start the service
sudo systemctl start socktop-agent
# Check status
sudo systemctl status socktop-agent
```
### Configure the agent
Edit the systemd service to customize settings:
```bash
sudo systemctl edit socktop-agent
```
Add configuration in the override section:
```ini
[Service]
Environment=SOCKTOP_PORT=8080
Environment=SOCKTOP_TOKEN=your-secret-token
Environment=RUST_LOG=info
```
Then restart:
```bash
sudo systemctl restart socktop-agent
```
## GitHub Actions
The project includes a GitHub Actions workflow (`.github/workflows/build-deb.yml`) that automatically builds `.deb` packages for both x86_64 and ARM64 architectures on every push to master or when tags are created.
### Downloading pre-built packages
1. Go to the [Actions tab](https://github.com/jasonwitty/socktop/actions)
2. Click on the latest "Build Debian Packages" workflow run
3. Download the artifacts:
- `debian-packages-amd64` - x86_64 packages
- `debian-packages-arm64` - ARM64 packages
- `all-debian-packages` - All packages combined
- `checksums` - SHA256 checksums
### Release packages
When you create a git tag starting with `v` (e.g., `v1.50.0`), the workflow will automatically create a GitHub Release with all `.deb` packages attached.
```bash
git tag v1.50.0
git push origin v1.50.0
```
## Package Details
### socktop package
- **Binary**: `/usr/bin/socktop`
- **Documentation**: `/usr/share/doc/socktop/`
- **Size**: ~5-8 MB (depends on architecture)
### socktop_agent package
- **Binary**: `/usr/bin/socktop_agent`
- **Service**: `socktop-agent.service`
- **User/Group**: `socktop`
- **State directory**: `/var/lib/socktop`
- **Config directory**: `/etc/socktop` (created but empty by default)
- **Documentation**: `/usr/share/doc/socktop_agent/`
- **Size**: ~5-8 MB (depends on architecture)
## Uninstalling
```bash
# Remove packages but keep configuration
sudo apt remove socktop socktop_agent
# Remove packages and all configuration (purge)
sudo apt purge socktop socktop_agent
```
When purging `socktop_agent`, the following are removed:
- The `socktop` user and group
- `/var/lib/socktop` directory
- Empty `/etc/socktop` directory (if empty)
## Verifying Packages
Check package contents:
```bash
dpkg -c socktop_*.deb
dpkg -c socktop_agent_*.deb
```
Check package information:
```bash
dpkg -I socktop_*.deb
dpkg -I socktop_agent_*.deb
```
After installation, verify files:
```bash
dpkg -L socktop
dpkg -L socktop-agent
```
## Troubleshooting
### Service fails to start
Check logs:
```bash
sudo journalctl -u socktop-agent -f
```
Verify the socktop user exists:
```bash
id socktop
```
### Permission issues
Ensure the state directory has correct permissions:
```bash
sudo chown -R socktop:socktop /var/lib/socktop
sudo chmod 755 /var/lib/socktop
```
### Missing dependencies
If installation fails due to missing dependencies:
```bash
sudo apt --fix-broken install
```
## Creating a Local APT Repository (Advanced)
To create your own APT repository for easy installation:
1. Install required tools:
```bash
sudo apt install dpkg-dev
```
2. Create repository structure:
```bash
mkdir -p ~/socktop-repo/pool/main
cp *.deb ~/socktop-repo/pool/main/
```
3. Generate package index:
```bash
cd ~/socktop-repo
dpkg-scanpackages pool/main /dev/null | gzip -9c > pool/main/Packages.gz
```
4. Serve via HTTP (for testing):
```bash
cd ~/socktop-repo
python3 -m http.server 8000
```
5. Add to sources on client machines:
```bash
echo "deb [trusted=yes] http://your-server:8000 pool/main/" | \
sudo tee /etc/apt/sources.list.d/socktop.list
sudo apt update
sudo apt install socktop socktop-agent
```
## Contributing
When adding new features that affect packaging:
1. Update `Cargo.toml` metadata in the `[package.metadata.deb]` section
2. Add new assets to the `assets` array if needed
3. Update maintainer scripts in `socktop_agent/debian/` if needed
4. Test package building locally before committing
5. Update this documentation
