Possible disadvantages of Portmap.io

    Using port forwarding services can introduce security risks if not properly configured or if the service has vulnerabilities.

  • Dependency on Third-party Service
    Relying on an external service for port forwarding can be a disadvantage if the service experiences issues or discontinues.

  • Limited Offline Use
    Since RegExr is a web-based application, it requires an internet connection, limiting its utility for users who need to work offline.
  • Learning Curve
    While the tool is user-friendly, users still need to have a foundational understanding of regular expressions to use RegExr effectively.
  • Performance Issues
    For extremely large inputs or very complex regular expressions, the tool may experience performance lags or slowdowns.
  • Limited Advanced Features
    RegExr may lack some advanced features found in more specialized or professional regex tools, such as integration with development environments or extensive scripting capabilities.
  • Privacy Concerns
    Users inputting sensitive data need to be cautious, as the web-based nature of the tool could raise privacy or data security concerns.

  • SSH into a personal computer in Jio Network using public IP
    I have a personal computer in the Jio Network at my home and I want to access it using ssh from another network. But in order to port forward my router I am stuck since Jio uses CGNAT if I am not mistaken and there is no use if I portforward. What other solutions do I have? I tried using portmap.io but I couldnt configure ssh in it (I dont want to use openVPN) so what other options do I have? Source: over 2 years ago

  • The importance of the environment in Regex pattern matching

    I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches.
