This is my first release of ldNetDeviceManager.py. The ldNetManager.py tool gives you the ability to manage your network devices with out having to purchase a product like Cisco’s LMS or go through the planning phase of deploying a product like func. Each of the tools I mentioned before, 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. And that is to update your devices with out 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. Once you have those 2 requirements fullfilled, then you are pretty much ready to go.
You will need Python 2.4 or better and Pexpect. ( has not been tested with Python 3+ )
You can get Python from http://python.org and Pexpect ( I’m currently using Pexpect 2.3, which you can get from SourceForge.

At the current place that I work at, we are trying to figure out, how much we are logging on a daily basis. Since my manager is thinking of purchasing Splunk ( I hope he does ). But before we make that leap and spend that much money ( Those of you who have splunk know exactly what I am talking about ). We need to know how much we are logging now and how much we would be logging after all of our devices are in Splunk.
The current issue is that we have over 400 Cisco Network devices, and they are not all in the Cisco LMS ( Lan Management Solution ). We also have Solarwind, but we do not have all of our Networking devices in there either. There is only one way I know of doing that with out using multiple tools like Cisco LMS or Func. So I figured, I should go ahead and write a Python tool that can update all of our devices ( Cisco, Nortel, Foundry, Linux, BSD, you get the idea.. ).
I wrote a Python tool that utilizes pexpect. The tools is almost complete to release on my site, but I still need to add more functionality. Currently, you can pass a device list and a command list to the script. You can also tell the tool to be verbose and print the output. Also you can tell it to use ssh or telnet or both. The tool is smart enogh to use ssh keys or log into a device you never have logged into before, by accepting the key for you.
I’m currently modifying it so that you can just pass one device and not just a list of devices. Also working on a password changer function. I’ve tested my tool on Linux Servers as well as Cisco devices and so far it works like a charm. I’m thinking about adding threading, but I have not yet decided to do so..
I will post this tool either tonight or tomorrow.. I hope you will find this tool as useful as we do.
