FTP Access Supported Web Hosting Service

Some web designers have often used different kinds of Hyper-Text Markup Language editors, such as text editors, object editors, and What You See is What You Get editors, to develop web pages off-line. And after that, they will upload those pages on the server of their web hosting provider to make those webpages accessible on the World Wide Web. There are many different ways to publish a file relating to web development technologies, such as HTML files and Cascading Style Sheets.

The two common ways to upload a web page file on the web hosting server, are by using a FTP account and via file manager on the control panel of a web hosting service. But the best way to upload files on a web server is by using a FTP account, but for you to be able using it, your web hosting provider must supports by the FTP access to allow you to create a FTP account because that account is required to access on the FTP server of your web host. FTP is an abbreviation for the word File Transfer Protocol. The FTP with web host is a standard network protocol to transfer files related to a website, on the web server over the Internet. FTP login uses a username and password scheme for granting access. The username is sent to the server with the USER command, and the password is with the PASS command. If the login detail that have been provided by the client is accepted by the server, the server will send a greeting to the client, and then the session will start. After that, the client may now log in without logging in again, but some servers authorize a limited access for such sessions.

The web hosting provider must supports the FTP access to be able their client to transfer a file on their web hosting server, because not all web hosting companies are accessible by file transfer protocol. A web host that accessible of FTP is a kind of service compatible for a web designer who build web pages off-line which then published on a host to make online and accessible on the World Wide Web. Always remember, if you're going to use an application software to develop a website such as offline HTML editor, it is better if the web hosting service that you're going to use is allowing their users to create a FTP account because publishing files using FTP is still the best way to transfer web page files from a local computer to a web hosting server.

What are FTP, FTPS, SFTP, and FTP Over SSH?

FTP is the official abbreviation for the word File Transfer Protocol. It is a standard network protocol for transferring files from one host or to another host on the Internet. FTP is commonly used by web developer to transfer the files of their website from their local computer to the computer which acts as their web hosting server to make their site online for everyone on the Internet. It can also used to download programs and other files to your computer from other servers. The web browser of your computer can make a FTP request to download the program that you have selected from a web page. By using FTP, you need a FTP account because you will going to use it to log on to the FTP server. And after that, you can now manage the files at the server, such as editing, renaming, moving, copying, and deleting a file.

FTP login will send a username and password scheme to the server for granting access. The username is sent to the server using the USER command, and the password is sent using the PASS command. If the login detail that have been provided by the client is accepted by the server, the server will send a greeting to the client and the session will start. And if the session has commence, the user may now log in without logging in their username and password again, but most servers authorize a limited access for such sessions. FTP was not developed to be a secure protocol, that's why it has many security weaknesses for this generation. FTP can't able to encrypt its transmissions by itself, such as usernames, passwords, commands, and data. They are can be read by anyone in clear text via performing packet capture or sniffing on a shared Internet connection.

The solution to the security problem of file transfer protocol is to use the secure versions of the insecure protocols, such as a FTPS or another kind of secure protocol that can protect the data on a public network. FTPS which also known as FTP over SSL and FTP Secure, is a protocol developed for transferring files over a secure connection. It still uses the technology of original FTP but it adds SSL, the same security that used for Hypertext Transfer Protocol Secure a HTTP over SSL which means Secure Sockets Layer a predecessor of Transport Layer Security. SSL and TLS are cryptographic protocols that provide communication security over the Internet. They encrypt the segments of network connections at the application layer for the transport layer.
