The directory structure under Unix System Services (USS) is shown below. The space requirements are approximate upper limits.
Symbolic link to the zFS (Space: 200 MB, 200 Cyls, read/write) that contains executable binaries, setup scripts, configuration files, server key files, manual pages, documentation, license agreement, example JCL scripts.
After installation, Tectia Server for IBM z/OS consists of a directory structure under the
zFS file system defined for it. The zFS is mounted onto a mount point defined at
installation, and pointed to by the
Each z/OS user account that is accessed via Tectia Server or that runs SSH
client programs normally has a USS home directory
$HOME, for example,
/u/home1/username) and under it a
.ssh2 subdirectory. The
directory contains the user's configuration files and keys. The home
directory is required if public key user authentication is used and if
user-specific configuration is needed.
Space: 128 kB, read/write
The runtime programs of Tectia Server for IBM z/OS create the
$HOME/.ssh2 directories as needed. If you want these
directories to be a link to some other spot in your directory hierarchy,
create the link before running the program.
Contains server process ID files and the default
Space: 256 kB (300 MB during installation), read/write/sticky.
/tmp directory must exist in advance and it
must be user-writable and have the sticky bit on.
The sticky attribute for
/tmp can be checked by
observing the output of ls and verifying that the letter
t is present in the permissions field:
:> ls -ld /tmp/. drwxrwxrwt 89 WEBSRV SYS1 49152 Apr 11 14:43 /tmp/.
If the permissions differ from
rwxrwxrwxt, they must be
adjusted with chmod:
:> chmod 1777 /tmp/.
Contains users' temporary files used in Secure Shell agent forwarding.
The agent forwarding status files are temporary and valid only while the actual user process is running.
Space: 12 kB for each user, read/write
