There is still some kind of crappy limitation with GNS3 and getting my Loopedback VLAN to communicate with the PC devices in ACME Co LAN - However I do have reachability on the Network Devices to play with some local configs in this lab! I have just recently started to use GNS3 and am not … Continue reading Python3 Network Programming – NAPALM for Network Device Configuration, lots of troubleshooting and good to knows for Network Engineers in this content (which will be continued)!
To round off the Netmiko section of Python3, I'd like to show a script that will standardize the entire network here with NTP and Buffered Logging, as those two things should be absolutely configured on a network for troubleshooting purposes. The configs shown are very minimal, and definitely not best practice for production networks, which … Continue reading Python3 Network Programming – Deploying base NTP / Logging across entire network, best practices, and the raw script at the very end of the post!
Being as I have been tanking through just touching network devices with Python, I wanted to take a step back, and look at the components within the script that call out each others to function properly and how to start thinking about writing scripts freestyle that suits your needs and begin thinking diving deeper into … Continue reading Python3 Network Programming – Review of a Netmiko Python Script, Python Terminology, and how different pieces reference each other in a script!
It is time to ditch the SSH and move onto Netmiko that would actually be used in most production networks, which involves a bit more than "enable ssh" if you have not turned it on before / turned off telnet, but I will demo it here of course via Automation! I am still continuing on … Continue reading Python3 Network Programming – Enabling SSHv2 and Disabling Telnet using Automation, and how to secure your network by enabling SSHv2 and disabling Telnet (very carefully)!
