Perl

A bit off topic, but I found this interesting math trick, called Kaprekar's constant.

If you take four digits and perform a series of simple functions upon them, the end result is 6174.

Summary: Quick and dirty scripts to fetch IOS config "show run" from multiple devices.

Setup

Copy the files to a working directory (i.e. c:\ciscoconf). The scripts are in .exe format, but if you want to run or edit the perl, those are provided.

If you plan on running the scripts from any where, you need to add the scripts to your DOS path. You need to be familiar with DOS to run these scripts.

Usages:

Single Command Line for a device configured for local authentication or AAA authentication. From the DOS prompt.

ciscoconf.exe 1.1.1.1 username password

Single Command Line for a device configured with a line password. From the DOS prompt.

ciscoconf-linepass.exe 1.1.1.1 line_password enable_password

Batch Mode - You can also create a batch file (i.e. getconfig.bat). We have provided a sample .bat file for you to edit.

@ECHO OFF
ciscoconf 1.1.1.1 username password
ciscoconf-linepass 2.2.2.2 line_password enable_password
