Each z/OS user account that runs SSH client programs or accesses the server must have a USS home directory ($HOME, for example, /u/home1/username). The system will create the .ssh2 directory under the home directory. It contains the user's configuration files and keys.

SSH Tectia Server for IBM z/OS, when installed, mainly consists of a directory structure under /usr/lpp/ssh2. You may create a symbolic 'ssh2' link to the place where the directory structure resides under /usr/lpp or you may want to create a separate HFS or zFS file system for it.
The setup script and runtime programs of SSH Tectia Server for IBM z/OS create the /etc/ssh2 and $HOME/.ssh2 directories as needed. If you want any of these 'ssh2' directory levels to be a link to some other spot in your directory hierarchy, create the link before running the setup script or program.
The /tmp directory must exist in advance and it must be user-writable.
The SSH agent forwarding status files under /tmp are temporary and valid only while the actual user process is running.
Although this version of SSH Tectia Server for IBM z/OS must be installed in a USS file system and use the directory structure shown above, the server supports the transfer of MVS files and all the programs can be executed in JCL by BPXBATCH, BPXBATSL, and oshell.
