Nmap (or Network Mapper) is probably the most popular network mapper around. However if you are running a very stable long-term support server, there are chances that your nmap database installation isn’t keep up to that.
Updating Nmap database
Nmap detection database consists of these files:
- nmap-os-db
- nmap-mac-prefixes
- nmap-payloads
- nmap-protocols
- nmap-rpc
- nmap-service-probes
- nmap-services
What you need to do is to download these files from Nmap Github project page and copy it to /usr/share/nmap/ folder.
Alternatively, you can use this script ‘nmap-update.sh’ which I’ve created based on this gist.
