Overview

SFTP is a secure method for transferring files between two computers. SFTP can stand for either SSH File Transfer Protocol or Secure File Transfer Protocol. This post will introduce you to the major functions of SFTP, its differences and similarities with FTP, its basic usage, and other important characteristics.

Overview

Server to server file transfers are usually associated with enterprise business processes. Interestingly, some of these file transfers actually don't fit the bill. In this post, we'll share some tips on how you can enhance your server to suit the stringent requirements of the enterprise.

Once the crooks have obtained our login credentials, they can just simply login to our FTP server and grab whatever files they find.

Overview

If you google the term secure FTP, most of the definitions you'll come across will fall into one of two groups: those that are just too technical and those that are simply too vague. Some, even contradicting. So if you're an average guy with a not-so-technical background, you'll be walking away with a head all tangled in arcane networking acronyms.

Overview: Secure File Transfer Systems

Normally, when people send files over the Internet, they do it through email, FTP, or cloud-based file sharing services. That's perfectly fine if the files you send don't contain sensitive information. But if they do, you would have to employ a secure file transfer solution in order to prevent possible attackers from intercepting, viewing, stealing, or altering the information you transmit.

JSCAPE is pleased to announce the release new versions of it's Secure FTP Factory (9.0), Secure iNet Factory (9.0) and SSH Factory (4.0) Java networking components suites.

The changes made as part of these releases are centered around the SSH and SFTP protocols and include the following:

• Enhancement - Ability to set the maximum incoming window size on the Ssh class.
• Enhancement - Ability to respond to OpenSSH keep alive request.
• Enhancement - Ability to set the file modification time using Sftp class.
• Bug Fix - Fix issue with Ssh and Sftp class automatically closing channels upon a server disconnect.

In addition to the information below, we're offering a free trial when you contact your account manager.

SCP is another old SSH (Secure Shell) file-transfer protocol — it can be traced back to the rcp command that was added to BSD Unix in 1982, which makes it the same age as ET The Extraterrestrial. It may have been the protocol ET used to communicate with his mothership. If he had had JSCAPE's Secure FTP Factory library, things might have gone more easily.

If you're a programmer, you've already learned dozens of TLA's (Three Letter Acronyms). If a phrase has four words, of course, we don't call the acronym an "FLA" because any civilian could understand that. We call it an ETLA (Extended Three Letter Acronym)! In the previous article, you saw how to use JSCAPE's Secure FTP Factory to safely transmit files using the fine ETLA FTPS. This time, we'll show you an even better way to transfer files securely using the even cooler ETLA SFTP. Being able to remember things like this is the mark of a professional programmer.

When two little kids want to exchange a secret, a lot of negotiation is necessary: "Promise you won't tell? Cross your heart and hope to die?". When a client and server computer want to exchange secrets, they need to negotiate too: public keys, encryption methods, ports and more. Fortunately, JSCAPE's Secure FTP Factory and server software (such as JSCAPE MFT Server) handle most of the details for you.

Here's some philosophy to go with the Secure FTP Factory library. There are some things in life that you should never do unless you feel completely secure. One of them is withdrawing money from an ATM. You should do this only in a safe, well lit and preferably high traffic environment where you are unlikely to be robbed. Another is uploading or downloading files using plain FTP (File Transfer Protocol).
