- SFTP Port Forwarding: Enabling Suppressed Functionality
- introduction The SSH protocol supports three major categories of remote server activities: a) command execution (including login shell), b) network forwarding and operation, and c) file transfer. OpenSSH maintainers have determined that sftp and scp have no legal purpose for port forwarding (via the -L and -R options). During file transfer using these utilities, a flag that explicitly disables these features is passed unconditionally to the child SSH executable. Some users may indeed need these features. An obvious subset is the penetration testers whose task is to verify that this feature is explicitly disabled on a public SFTP server. Here are two techniques to enable these suppressed functions by modifying the sftp binary file

- Enhancing Structural Markup with JavaScript
- Key Points Enhanced structured tagging with JavaScript can significantly improve the accessibility and maintainability of web page content while reducing file size. JavaScript can be effectively used to dynamically add functionality to HTML elements, such as using the cite attribute to automatically insert reference links into block references. Integrating JavaScript with structured tags allows you to create dynamic user interfaces, such as tab panels that do not require page refresh. It is crucial to ensure that JavaScript enhancements do not hinder the basic functionality of web pages; even if JavaScript is disabled, the page should remain functional. Advanced JavaScript technology can be used (

- jQuery String Contains Functions
- No jQuery is required, just use pure JavaScript to tell whether a string contains another string! Here is how to operate: if (str.indexOf("Yes") >= 0) Note that this method is case sensitive.

- jQuery set innerText(), innerHTML(), textContent()
- Core points jQuery combined with JavaScript can modify the text content of HTML elements to include new text, images, code, etc. This article focuses on three jQuery functions: innerText(), innerHTML() and textContent(). The innerText() function reads and writes the text between the element's starting tag and the end tag, including line breaks; the innerHTML() function modifies HTML in the page element, but removes line breaks; the textContent() function modifies the text of the page element, and also removes line breaks. There is a line break problem with the textContent() function: it doesn't look like in

- Form Validation on the Client Side
- Client form validation is crucial – it saves time and bandwidth and provides more options to point out where users make mistakes when filling out forms. That being said, this doesn't mean you don't need server-side verification. Users visiting your website may have used an old browser or disabled JavaScript, which will break client-only verification. Client and server-side verification complement each other, so they really should not be used independently. Why is client verification important? There are two good reasons to use client authentication: It is a quick way to verify: if something goes wrong, an alert will be triggered when the form is submitted. You can safely display only one error at a time and focus on the wrong fields to help ensure that the user correctly fills out all the detailed letters you need
