SolarWinds: free network config generator

A few days ago I received a notification from SolarWinds that they released a free Network Config Generator software and I was invited to download and test it.

I give it a try and even if I’m more used to the old plain text files with configuration template, this software was a pleasant surprise. I recommend it especially for those how are new in business and are beginners with Cisco devices. This software can get you out from some troubles when you are configuring Cisco platforms.

I had the idea to make a video tutorial about how to use it, but then I found the 2 videos below created by SolarWinds which give you an overview about this software and then a short how-to use it:

And the how to guide:

SNMP Version 3 Authentication Vulnerabilities

Multiple Cisco products contain either of two authentication vulnerabilities in the Simple Network Management Protocol version 3 (SNMPv3) feature. These vulnerabilities can be exploited when processing a malformed SNMPv3 message. These vulnerabilities could allow the disclosure of network information or may enable an attacker to perform configuration changes to vulnerable devices. The SNMP server is an optional service that is disabled by default in Cisco products. Only SNMPv3 is impacted by these vulnerabilities. Workarounds are available for mitigating the impact of the vulnerabilities described in this document.

Vulnerable products:
# Cisco IOS
# Cisco IOS-XR
# Cisco Catalyst Operating System (CatOS)
# Cisco NX-OS
# Cisco Application Control Engine (ACE) Module
# Cisco ACE Appliance
# Cisco ACE XML Gateway
# Cisco MDS 9000 Series Multilayer Fabric Switches
# Cisco Wireless LAN Controller (WLC)
# Cisco Application and Content Networking System (ACNS)
# Cisco Wide Area Application Services (WAAS)
# Cisco MGX 8850, 8880 Media Gateway and Switch
# Cisco PSTN Gateway (PGW2200)

Cisco ISR G2 Series

Cisco – Remote VTY Command Script

Running one or more interactive CLI commands is a common task in network management. Having a script to automate this task becomes a critical tool.

This script automates interactive TELNET or SSH sessions. Any command that can be issued in CLI can be issued via the VTY run command script in an automated fashion. Below are some example uses:

* Run a set of commands on hundreds of devices
* Configuration changes
* Archive configurations and software
* Audits, inventory and discovery
* Automated troubleshooting

Requirements

This script is written in Expect. A current version of Expect is required. Expect and installation requirements for Expect can be found at Expect Homepage

Tested on RHEL 5 running expect 5.43.0-5.1 and Mac OS X 10.6 running Expect 5.44.1.11.

The script is platform independent and should run on any platform that can run Expect.
