OpenSSH provides secure encryption for both remote login and file transfer. Some of the utilities that it includes are:

  • ssh, a z/OS client program for logging into a z/OS shell. It can also be used to log into other platform's UNIX shells. It is an alternative to rlogin.
  • scp for copying files between networks. It is an alternative to rcp.
  • sftp for file transfers over an encrypted ssh transport. It is an interactive file transfer program similar to ftp.
  • sshd, a daemon program for ssh that listens for connections from clients. The IBM Ported Tools for z/OS: OpenSSH implementation of sshd supports both SSH protocol versions 1 and 2 simultaneously.

Other basic utilities such as ssh-add, ssh-agent, ssh-keysign, ssh-keyscan, ssh-keygen, and sftp-server are also included.

To ensure secure encrypted communications, OpenSSH uses ciphers such as Blowfish and 3DES.
