FTP is often a matter of choice for users. This is especially true when the FTP client they use is behind a Firewall. FTP in passive mode is easier to operate and better suited for firewalls and NAT routing.
FTP (Internet Protocol) is a protocol which allows file transfers between two computers. FTP protocol consists of a data and a commands channel that are both used to transfer information between client and server.
The client initiates communication with the FTP by sending an PORT command via TCP Port 21. The server responds to this by connecting back on its local data port (typically TCP port 20) to the specified data port of the client.
The connection will work unless your FTP client is hidden behind a firewall. In this situation, the client firewall will block incoming connections requests from the FTP server. This would prevent any file transfers.
One way to solve this problem is to change the client's mode from active to passive. In passive-mode, the FTP Client still initiates command channel. But instead of sending a command to establish data connection (PORT), it sends PASV. The FTP Server then responds to the PASV Command by indicating what (random) data ports it has already opened for the subsequent file transfer.
In Active mode, the client also sends a PORT command to initiate the data channel with the FTP server. This mode is a reverse channel that's not as friendly for firewalls and NAT devices as passive mode.
Firewalls can help secure networks. They do this by only allowing specific types of traffic through certain ports. This is often done as a way to protect against unauthorised access. However, it can also lead to problems when you use FTP.
Network Address Translations (NATs) are a common way of protecting against unauthorised connections. These devices let multiple computers share one IP address but they can also be used as firewalls for connections from outside. NATs can be very effective at blocking external connections, but they are difficult to configure to support firewall support.
In order to reduce the amount of responsibility that the client has for the firewall configuration, the passive mode was developed. In passive, the client will still initiate the control channel using port 21, however, instead of sending a PASV, it will send a PASV. This command is used to tell the FTP Server to return an address and port number to the client for a data channel.
If you are running Fetch with an Automatic Passive Mode feature enabled, you will automatically be switched to passive mode when Fetch is running on a firewall and receives an error trying to make a connection. You can manually activate passive mode if this doesn't help. Select the Passive Mode menu option in the FTP Settings.
Clients can choose between active or passive mode, though passive mode is usually better for NATs and Firewalls. The client may be configured to use only a small range of high port numbers on the host, which limits the number that can potentially be blocked by the firewall. This will also decrease the risk to the server from a firewall that may block all traffic on a high-level port, but will not remove all of the security issues associated with a firewall.

How To
What is website hosting?
Website hosting is the place where visitors go to visit a website. There are two types:
-
Shared hosting is the cheapest. Your website files are stored on a server that is owned by another person. Customers who visit your website send their requests via the Internet over to that server. The request is then handed to the owner of that server.
-
Dedicated hosting is the most expensive option. Your website is hosted entirely on one server. No other websites share space on the server, so your traffic stays private.
Shared hosting is preferred by most businesses because it's cheaper than dedicated hosting. When you use shared hosting, the company that hosts the server gives you the resources to run your site.
Each option has its pros and cons. These are the key differences between them.
Shared Hosting Pros
-
Lower Cost
-
Easy to Setup
-
Frequent Updates
-
It can be found at many web hosting providers
Shared hosting can often cost as little as $10/month. However, this price typically includes bandwidth. Bandwidth describes the amount of data that can be transferred over the Internet. Even if only you upload photos to your blog or website, high-volume data transfers may incur additional charges.
Once you begin, you will soon see why you spent so much on your previous host. Most shared hosts provide very limited customer support. Although their techs may help you with setting up your site, it's not a common practice.
You'll want to look into a provider that offers 24-hour phone support. They will attend to any issues you have while you sleep.
Cons of dedicated hosting
-
More Expensive
-
Less Common
-
Specific Skills Required
You're getting everything you need with dedicated hosting to operate your website. You won't have to worry about whether you're using enough bandwidth or whether you've got enough RAM (random access memory).
This means you will need to spend more upfront. You'll soon realize that your business is self-sufficient once it's online. You'll become an expert at managing your servers.
Which Is Better for My Business?
The answer to this question depends on which type of website you wish to create. If you're selling products only, shared hosting might work best. It is easy to set-up and manage. A server shared with several other sites means that you will receive frequent updates.
However, dedicated hosting can be a great option if you're looking to build a community around the brand. You can put your efforts into building your brand, and not worry about how to handle your traffic.
Bluehost.com has both. They offer unlimited data transfers per month, 24/7 support and free domain registration.
