SecureCRT Scripts

Collection of SecureCRT Python scripts for network operations and troubleshooting workflows.

This repository consolidates reusable tooling into a single location with consistent structure and behavior.

Scripts

OUI Lookup

Offline MAC → vendor lookup using Wireshark manuf.txt.

  • Detects MAC from screen, clipboard, or input
  • Displays vendor
  • Optionally runs ARP lookup

Path: oui-lookup/oui-lookup.py

Cable Test

Automates TDR cable diagnostics on supported Cisco platforms.

  • Extracts interface from screen/selection
  • Runs TDR test
  • Waits for completion
  • Displays results

Path: cable-test/cable-test.py

Quick Logo All

Closes all SecureCRT tabs cleanly.

  • Sends exit to all connected sessions
  • Skips disconnected tabs
  • Closes all tabs except current

Path: quick-logo-all/quick-logo-all.py

Design Principles

  • No hardcoded paths
  • Scripts operate on active SecureCRT context
  • Prefer detection over user input
  • Safe execution (confirm before sending commands)
  • Portable across environments

Usage Model

All scripts are intended to be:

  1. Run inside SecureCRT
  2. Context-aware (selection, screen, clipboard)
  3. Fast to execute during live troubleshooting

Structure

Each script is self-contained:

  • script file
  • README
  • supporting data (if required)

This allows scripts to be:

  • reused independently
  • tested in isolation
  • expanded without affecting others

Future Improvements

  • Standard argument handling
  • Shared helper module
  • Logging consistency
  • Additional network automation scripts
