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 /opt/tectia symlink.

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 .ssh2 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 STDOUT and STDERR.

Space: 256 kB (300 MB during installation), read/write/sticky.

The /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
