FTP passive vs. active is a consideration that most users should take into account, especially if their FTP client is being used behind a security firewall. Passive mode FTP makes it easier to use. It is also more friendly with firewalls, NAT routers, and other security measures.
FTP is a protocol that uses the Internet (IP) to transfer files between computers using a client or server. FTP is composed of two channels, a data channel and command channel. Both are used to send information between the client computer and the server.
The client initiates a command channel with the FTP Server by sending a TCP port 21 PORT command. The server will respond by connecting to the specified client data ports on its local port, typically TCP Port 20.
This connection process will work as long the FTP Client is not behind a Firewall. In that case, the client's firewall will block the incoming connection request from the FTP server, which would prevent the file transfer from occurring.
A simple solution to this problem is changing the client mode from active into passive. In passive mode the FTP client initiates the command channel but instead of sending the PORT command, it sends the PASV command. The FTP client replies to this command with a random data port that it has open for the file transfer.
In Active mode, the client also sends a PORT command to initiate the data channel with the FTP server. It is a reversed data channel and therefore not as compatible with firewalls or NAT routers.
Firewalls, which are software pieces that secure networks through limiting certain traffic types to specific ports, help keep them safe. It's often done in order to prevent unauthorized entry, but this can also create problems when using FTP.
Network Address Translation devices (NAT) are another way to prevent unauthorized connections. These devices are used to enable multiple computers to share the same IP address. They can also serve as a firewall when external connections arrive. NATs work well at blocking access to internal servers but are hard to configure as firewalls.
In order to reduce the amount of responsibility that the client has for the firewall configuration, the passive mode was developed. In passive mode, the client still initiates the control channel on port 21, but instead of sending a PORT command, it sends a PASV command. This command tells the FTP server to return an IP address and port number for the client to create a data channel on.
When you run Fetch on a firewall, and you receive an error when trying to connect, the Automatic Passive Mode will be automatically switched to passive mode. You can manually activate passive mode if this doesn't help. Select the Passive Mode menu option in the FTP Settings.
Passive mode works best with firewalls and NATs. A client can be configured so that it only uses a certain range of high level ports on the servers. This limits the number of ports which can be blocked by firewalls. This also reduces the risks to the server of a blocking firewall.
FAQ
Should I use WordPress, or a website builder
A small website is the best way to build a successful web presence. If you have the time or resources to create a complete site, do so. A simple blog is a good option if you don’t yet have the necessary resources. As you learn how websites are designed and developed, you can always add more features.
Before you start building your website, it is important to establish a primary domain. This will provide a point to which you can publish content.
What is a website static?
A static website contains all content stored on a server that visitors can access via web browsers.
The term "static" refers to the fact that there are no dynamic features such as changing images, video, animation, etc.
This type of site was originally developed for use in corporate intranets but has since been adopted by individuals and small businesses who want simple websites without the complexity of custom programming.
Because they are less maintenance-intensive, static sites have gained popularity. They are much easier to maintain than fully-featured sites with many components (such a blog).
They also tend to load faster than their dynamic counterparts. This makes them great for those who have slow Internet connections or users with mobile devices.
A static website is more secure than its dynamic counterparts. Static websites are much harder to hack than dynamic ones. Hackers have limited access to data within a database.
There are two main methods to create static websites:
-
A Content Management System (CMS),
-
Creating a Static HTML Website
The best one for you will depend on your specific needs. I recommend a CMS if you're just starting to create websites.
Why? Because it gives you complete control of your website. You don't need to hire someone else to help you set it up. Upload files to the web server.
You can still learn to code and make a static website. It will take some time to learn to program.
What is a website static?
A static website can be hosted anywhere, including GitHub Pages, Amazon S3, Google Cloud Storage, Windows Azure Blob storage, Rackspace Cloud Files, Dreamhost, Media Temple, and others. A static website can be also deployed to any platform supporting PHP, including WordPress, Drupal and Joomla!, Magento, PrestaShop and others.
Static web pages can be easier to maintain as they don’t need to send requests back and forward between servers. A static web page loads faster as there is no need to forward requests back and forth among servers. These are just a few reasons why static web pages can be a better option for small companies who don't have the resources or time to maintain a website.
