Running SSH Tectia and OpenSSH in a z/OS Environment
SSH Tectia Server for IBM z/OS installs always under /usr/lpp/ssh2, so the SSH Tectia and OpenSSH binaries are not confused. Configuration files and host keys are stored in the /etc/ssh2 directory, compared to the /etc/ssh directory used by OpenSSH. User keys and other user-specific files are stored under $HOME/.ssh2, compared to $HOME/.ssh used by OpenSSH. The server port can be configured in the /etc/ssh2/sshd2_config file with the keyword Port. The default is 22, but it can be changed to any available port.
