Command Line Options

All configuration options can also be passed via command line:

# Start with custom config
csd -conf=/path/to/custom.conf

# Override config values
csd -dbcache=4096 -maxconnections=256

# Start in foreground for debugging
csd -printtoconsole

# Start with testnet
csd -testnet

# Specify data directory
csd -datadir=/path/to/data

Environment Variables

You can also use environment variables:

export CSCOIN_RPC_USER=your_user
export CSCOIN_RPC_PASSWORD=your_password
export CSCOIN_DATA_DIR=/path/to/data

csd -daemon

Configuration Best Practices

Security

1. Use strong passwords for RPC access
2. Restrict RPC access to localhost or trusted IPs
3. Don't expose RPC to the public internet
4. Use firewall rules to limit access
5. Keep software updated

Performance

1. Set appropriate dbcache based on available RAM
2. Use SSD storage for better I/O performance
3. Limit maxconnections to prevent bandwidth saturation
4. Enable pruning if disk space is limited
5. Monitor resource usage regularly

Reliability

1. Use systemd for automatic restart
2. Set up monitoring and alerts
3. Regular backups of wallet and config
4. Log rotation for debug files
5. Test configuration changes on testnet first
