| ### Nagios Bulk Import (nbi.pl) | |
| # | |
| #This perl script will take a nmap generated "grepable" file and create a host file for nagios | |
| # nmap <IP Range> -s[S|T|A|W] -O -oG <FILENAME> | |
| # ./nbi.pl <FILENAME> | |
| # You need to add the service.cfg, command.cfg & the hostgroups.cfg below to your existing files | |
