The script nk-compare-configs is part of Nelkit, its goal is to run audits on network device configuration to find hosts which config differ from your baseline.
The script needs a file which instructs it what you want to compare in the configuration. The config file is in yaml format and an example looks like this:
configs: '/opt/network/configs' # rules: # Match lines starting with snmp-server but ignore # the snmp-location setting - match: string: '^snmp-server' exclude: '^snmp-server location' # Match lines starting with logging - match: string: '^logging' # Match from the line starting with interface Loopback # to a line starting with "!" - between: start: '^interface Loopback0' end: '^!' # Match between interface Loopback1 and the next line # which isn't indented, exclude description and ip address - between: start: '^interface Loopback1' exclude: '^ description|^ ip address' until_not: '^ ' # Match an access-list - between: start: 'ip access-list extended OUTSIDE-IN' until_not: '^ ' # Match lines starting with service but sort the # lines before comparing so that the order in which # the configuration was entered is ignored - match: string: '^service' sort: 'true'
Once you have setup your settings file you can run the script.
nk-compare-configs -c settings.yml
