One of the most popular file transfer and remote login Linux applications is OpenSSH, which provides a number of ways to create encrypted remote terminal and file transfer connections between clients and servers. The OpenSSH Secure Copy (SCP) and Secure FTP (SFTP) programs are secure replacements for FTP, and Secure Shell (SSH) is often used as a stealthy alternative to TELNET. OpenSSH isn't limited to Linux; SSH and SCP clients are available for most operating systems including Windows.
