The ldNetManager.py tool gives you the ability to manage your network devices without having to purchase a product like Cisco's LMS or go through the planning phase of deploying a product like func. Such tools only have the ability to manage devices in their realm. Func supports Linux devices, and Cisco LMS supports only Cisco devices. This tool has one goal: to update your devices without deploying any software to your remote devices. All you need is either telnet or SSH access to your devices, and Python2.4 or better with Pexpect installed.
