Starlyng BCM Connection

A Python library for executing Baseboard Management Controller (BMC) commands on servers using IPMI.

Features

• Execute BMC commands on remote servers using IPMI via execute_bcm_command
• Parallel execution of commands across multiple servers using threading
• Comprehensive error logging and handling
• Support for common IPMI operations:
  • Power management (status, on, off, cycle, reset)
  • System Event Log (SEL) operations
  • Chassis control
• Flexible server configuration through BCMServer class
• Secure connection handling with IPMI over LAN (LANPLUS)
• Command output capture and structured response handling
• Utility functions for hostname and IP address management:
  • Generate consistent host IDs and hostnames
  • Handle both local and public IP configurations
  • VLAN-aware IP address management

Prerequisites

Before you begin, ensure you have:

• Python 3.9 or higher installed
• ipmitool installed on your system:
  • Ubuntu: sudo apt-get install ipmitool
  • macOS: brew install ipmitool
• If outside local network, configure port forwarding on your router:
  • Forward BCM port 623 to each server's unique port (62300-62399)
  • Example: Forward port 62300 to 192.168.50.1:623, port 62301 to 192.168.50.2:623
  • Port range must be between 62300-62399

Installation

pip install starlyng-bcm-connection

Usage

Basic Example

from bcm_connection import BCMServer, execute_bcm_command

# Create a BCM server instance
server = BCMServer(
    bcm_ip="192.168.1.1",
    bcm_user="admin"
    bcm_pass="password"
    bcm_port=623
)

# Execute a command
# Pass server in a list since execute_bcm_command expects List[BCMServer]
result = execute_bcm_command([server], "power status")
print(result)

Hostname and IP Management

from bcm_connection import get_hostname, get_host_id, get_ip_for_bcm

# Generate a hostname for a local server
hostname = get_hostname("server", "192.168.1.20", 623, public_ip=False)
# Result: "server10" (20 - 10 = 10)

# Generate a hostname for a public server
hostname = get_hostname("server", "203.0.113.1", 62345, public_ip=True)
# Result: "server45" (last two digits of port)

# Get BCM IP address with VLAN
bcm_ip = get_ip_for_bcm("192.168.1.20", vlan_id=50, public_ip=False)
# Result: "192.168.50.20" (VLAN ID injected)

Available BMC Commands

Common IPMI commands you can execute:

• power status - Get power status
• power on - Power on the server
• power off - Power off the server
• power cycle - Power cycle the server
• power reset - Reset the server
