The directory structure is shown below. The space requirements are approximate upper limits.
/usr/lpp/ssh2
Executable binaries, setup scripts, manual pages
Space: 300 MB, 400 Cyls, Read-only after installation
/etc/ssh2
Configuration files and keys for the server
Space: 32 kB, Read/write
$HOME/.ssh2
Each z/OS user account that runs SSH client programs or accesses the server must have a USS home directory. The system will create the .ssh2 directory. It contains the user's configuration files and keys.
Space: 32 kB, Read/write

SSH Tectia Server (M), 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 XFS file system for it.
The setup script and runtime programs of SSH Tectia Server (M) 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.
