USS
 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
 
 -  
/tmp   Server process ID files.         
 Space: 32 kB,   Read/write
 
 -  
/tmp/ssh-username   Users' temporary files used in SSH agent forwarding.     
 Space: 8 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.
