SSHD
z/OS 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 rcpt.
- 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 z/OS OpenSSH implementation of sshd supports SSH protocol version 2. SSH protocol version 1 is no longer supported.
With the IBM Z Security and Compliance Center, you can automatically collect data from SMF Type 1154 Subtype 78 to check whether z/OS OpenSSH sshd daemon is configured to only use the SSHv2 protocol, check whether OpenSSH is running in FIPS 140-2 mode with all applicable cipher algorithms implemented using ICSF, and more.
