Gnmap-Parser takes multiple Nmap scans exported in greppable (.gnmap) format and parses them into various types of plain-text files for easy analysis.
Parsing Formats Include:
- Alive Hosts List Based on ICMP Replies
- Alive Hosts List Based on Open Ports
- Host Type Lists Based on Open Ports
- Simple TCP/UDP Ports Lists Showing Unique Open Ports Discovered Across All Hosts
- Port Files In "[#]-[TCP/UDP].txt" Format Consisting of Ordered Hosts
- CSV Style Port Matrices In "[HOST],[PROTOCOL],[PORT]" Format
- Third-Party Tool Input File Formats (Currently: PeepingTom)
Supported Switches:
- -g = Gather .gnmap files (faster but only finds files with .gnmap extension).
- -gg = Heuristically gather .gnmap files (slower but finds files regardless of extension).
- -p = Parse .gnmap files.
Limitations:
-
Gnmap-Parser will only parse *.gnmap files that are in the same directory that it resides. For this reason, the gather switches (-g) and (-gg) were implemented to copy .gnmap files from their known locations into the scripts working directory. Any path will work as Gnmap-Parser will traverse all subdirectories. For instance, providing a parent directory of "/" will traverse the entire root filesystem looking for *.gnmap files.
-
Gnmap-Parser currently only parses files that end with the .gnmap extension. If using the -oA switch of Nmap, these files will already be named with the correct extension. If specifying the -oG switch, be sure to append .gnmap to the filename or use the (-gg) switch.
