SSH Tectia Server for IBM z/OS contains three client-side applications. ssh2 is used for secure remote terminal sessions, remote command execution, and tunneling. scp2 and sftp2 are used for secure file transfers.
ssh2 is a secure replacement for Telnet and other unsecured terminal applications. ssh2 can also be used for remote command and job execution, and creating secure tunnels for TCP applications.
scp2 is a secure replacement for remote copy (rcp) and provides easy secure non-interactive file transfers.
sftp2 is a secure replacement for FTP and provides a user interface for interactive file transfers and a batch mode for unattended file transfers.
