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
