Printer Connection Test & Data Collector Tool.

  • This GUI tool was designed to test HP & Xerox Printer Connectivity, and to collect HP/Xerox printer mib information.

Table of Contents

General Information

  • This project was developed for the requirements of a large customer with an inconsistent fleet configuration.
  • The purpose of this project is to enable the customer to perform discovery on HP & Xerox Devices on the existing printer estate.
  • Due to the technical challenges around device configurations, a tool was required to enable the team to feed in 30,000 IP's, and 1500+ SNMP Community strings from a CSV file based on a location identifier.
  • Some printers had ICMP turned off.
  • All printers allowed HTTP(s) Connections.
  • Printers hostname was unique - DNS FQDN naming convention partly used the printer vendor name. This could be used to identify printer type during discovery.
  • This tool tests printer connectivity via ICMP, HTTP/s and DNS, it also collects device information via SNMP and outputs results to a csv file for analysis.

Technologies Used

Features

The tool provides the following capabilities:

  • Printer Connection Checker. (Is there a printer on the IP? What Type?)

    • Ingest Printer information from CSV (Location ID, Printer IP, Vendor Default SNMP Community String).
    • Test Printer Connectivity via ICMP Ping.
    • Test Printer Connectivity via HTTP(s) Request. (Some Devices had ICMP Disabled but HTTP enabled).
    • HTTP check will do a web scrape and look for HP/Xerox identifiers to see what type of vendor the web service is running on.
    • Resolve Printer DNS to FQDN. (Customer used naming conventions for each printer vendor to allow for identification via CSV analaysis).
    • Output of results / information to csv format.
    • Output of logging for all functions to txt file.
  • SNMP Password Checker / Brute Forcer. (What Password matches what location/printer?)

    • Ingest SNMP Community passwords from csv (Location ID, SNMP Community String for Site).
    • Ingest Printer information from csv (Location ID, Printer IP, Vendor Default SNMP Community String).
    • This function will try to match the printer csv Location ID, to the passwords csv Location ID.
    • If there is a location match between printers and passwords, matched SNMP Community string ID will be used.
    • If no match then it defaults to the printers default SNMP password in printers csv.
    • The function will use either the location matched SNMP password, or the vendor default SNMP password to try and extract the printer serial number with said password.
    • If the SNMP Password used doesn't work, the serial value in output csv will be blank.
    • Output of results / information to csv format.
    • Output of logging for all functions to txt file.
  • SNMP Printer Data Collector (IPs and SNMP Passwords from previous two features can be fed into this DCA!)

    • Ingest Printer information from CSV (Location ID, Printer IP, SNMP Community String).
    • The tool is designed to collect the following SNMP OID data;
      • Site Code (Trigram)
      • Device Description (Model)
      • IP Address
      • MAC Address
      • Hostname
      • Location
      • Mono Counts
      • Color Counts
      • Total Counts
      • Serial
      • SNMPGET Community String
      • System Information (Firmware Versions)
    • Output of results / information to csv format.
    • Output of logging for all functions to txt file.
  • CSV File Viewer

    • Feature allows to select a CSV and then presents the information in a GUI Table.
    • Designed to be used if tool is being executed from a server with no excel for example.
    • Easier to view thousands of entries when not on a desktop.

      pip3 install -r requirements.txt
      

Usage

  • Running the project from source files;

    • Ensure all Dependencies are installed.

    • Populate the CSV file(s) as per the example entry provided.

    • Run

      python -m  nagini

Notes

  • All of the code is tested and the tool works.
  • Some of the code still needs refactoring into a decent state, i was in a rush! :o)
  • Some of the information on this README, and comments in code was to accomodate Code / Security Reviews.
  • I'm not responsible for how this tool is used.
