netcfgtooltelnet

Python script for pushing the same configuration (stored in a predefined file) on multiple devices at the same time via Telnet.

The script reads the IPs of the devices from the NETWORK_IP file and sends the commands you enter in the CMD_FILE file to all the devices. Telnet username/password parameters are configured within the script. This feature can be further customized to prompt the user for them or read them from a file.

The script also checks if all the needed files exist, if all the IP addresses are valid and if all the devices are reachable.

Tools used: Python 2.7.3, GNS3, Linux.
