SSH, or secure shell, is a protocol by which users can remotely log in, administer, or transfer files between computers using an encrypted transport mechanism. Running over every major operating system, SSH provides a more secure connection method than traditional telnet or the much-maligned "r commands" (rlogin, rcp, rsh). SSH includes provisions for key-based authentication that doesn't require a password, which opens the door for some innovative remote access applications. SSH works on a client/server model. A user runs SSH client software to connect to a server running SSH software that listens on a TCP port. Like telnet, SSH gives users a command-shell type interface into the computer. Unlike telnet, SSH encrypts the login credentials and all of the data flying over the wire. SSH and its related protocols, such as Secure Copy Protocol (SCP) and Secure File Transfer Protocol (SFTP), offer more secure alternatives to their unencrypted brethren.

Secure FTP solves the password security and port control problems by allowing the entire connection to take place through a single tunneled SSH connection. . . . . This article will point out the differences between standard FTP and secure FTP using some real-world examples. Secure FTP solves the password security and port control problems by allowing the entire connection to take place through a single tunneled SSH connection. If you're a firewall administrator (and most of us have learned to adopt this title in one form or another), your firewall rules just got easier. Now you can safely block your FTP ports access to the outside world - primarily the FTP default port, 21. The Secure FTP server has to be running OpenSSH, which accepts ssh1 and ssh2, and also needs to be running ftpd, the "normal" FTP daemon (more on this later). The Secure FTP client calls to the Secure FTP server on its SSH port. The server then connects internally to port 21, the FTP port, and tunnels the FTP data back across the SSH port to the client. To ensure the server is totally secure, you need to firewall off port 21 from outside access, only allowing the local host to connect to port 21. This is accomplished by either ipfw (firewalling) or tcpwrappers (under Unix, the hosts.allow file). The link for this article located at 8wire is no longer available. . FTP and SFTP are both file transfer methods, with SFTP providing enhanced security through encryption, ensuring safe data handling and user authentication.

I won't cover how to sniff connections, steal passwords or if SSH is really "secure". But hopefully, I can provide some information that will be valuable for your web hosting clients and for you -- the Apache webserver administrators. This first article covers a file transfer client for the end users -- it requires a secure shell server to be installed on the web server. Yes, Secure iXplorer is for Microsoft Windows. Basically, iXplorer is a Microsoft Explorer-like, graphical front-end to a modified pscp, which is a text-based (DOS) scp client for Windows. (Pscp is from the same author of the popular PuTTY SSH client). iXplorer seems to be a great option for Windows-only "webmasters" who need to upload files. And as an added bonus, it is open source -- the code is available. It was written in Delphi by Lars Gunnarsson of Austria and is available via http://www.i-tree.org/. It was officially released as version 0.3 in September 2000 and it has had active development the past several months with updates, bug fixes and improvements.
