– Simple Shell Script To Debugging Http/Https Traffic Tracing simple shell script to debugging http/https traffic tracing, response headers and mixed-content. Scanning domain using Nmap NSE Library. Support external security tools: Mozilla Observatory and SSL Labs API. is a shell script that allows you to validate your domain configuration and catch any errors (e.g. redirect loops). It also displays basic information about the ssl configuration (if available), response headers, checks for mixed content and performs security scans using Nmap scripts and great external tools such as Ssllabs or Mozilla Observatory.

It is useful for:

  • Checking properly domain configuration (web servers/reverse proxies)
  • redirects analysis, e.g. to eliminate redirect loops
  • checking response headers for each request
  • checking basic ssl configuration
    • validation of the certificates (date, cn, san) and verification ssl connection
  • scanning domain for Mixed Content
  • scanning domain using Nmap NSE Library
  • scanning domain with external security tools: Mozilla Observatory and SSL Labs API

Note: Before use please see Requirements.
