File Locations and Permissions on Unix

On Unix platforms, the SSH Tectia Server files are located in the following directories and the named file permissions are required for them:

/etc/ssh2
Writable to root (must). Readable to world. The /etc/ssh2 directory is created with the correct permissions during installation.
- /etc/ssh2/ssh-server-config.xml: the server configuration file (see ssh-server-config(5))
  Writable to root (must). Readable to world. The permissions can be overridden with environment variables SSH_SECSH_NO_OWNERSHIP_CHECKS and SSH_SECSH_DISABLE_OWNERSHIP_CHECKS.
- /etc/ssh2/ssh-server-config-default.xml: a sample file that shows the hardcoded system defaults of the server configuration
- /etc/ssh2/ssh-server-config-example.xml: a sample file with useful examples for the server configuration
- /etc/ssh2/hostkey: the default server host private key file
  Writable to root (must). Readable to root (must). The permissions can be overridden with environment variables SSH_SECSH_NO_OWNERSHIP_CHECKS and SSH_SECSH_DISABLE_OWNERSHIP_CHECKS.
- /etc/ssh2/hostkey.pub: the default server host public key file
  Writable to root (should). Readable to world.
- /etc/ssh2/random_seed: the seed file for the random number generator
  Writable to root (must). Readable to root (must). Set the permissions read/writeable to root at each update.
- /etc/ssh2/licenses: the license file directory (see Licensing)
- /etc/ssh2/ssh-tectia/auxdata/ssh-server-ng: the server configuration file DTD directory
- /etc/ssh2/trusted_hosts: the directory for host public keys that are trusted for host-based authentication (see Host-Based User Authentication)
  Writable to root (must). Readable to root (should).
/opt/tectia/sbin: the system binaries such as ssh-server-g3
/opt/tectia/bin: the user binaries such as ssh-keygen-g3
/opt/tectia/man: SSH Tectia Server man pages
/opt/tectia/libexec: library binaries
/opt/tectia/lib/sshsecsh: library binaries

The user-specific configurations are stored in each user's $HOME/.ssh2 directory.

Readable to user (must). Writable to user (should). The permission checking can be changed with configuration setting <auth-file-modes mask-bits="XXX"/>.

In the $HOME/.ssh2 directory:

$HOME/.ssh2/authorized_keys: the default directory for user public keys that are authorized for login
$HOME/.ssh2/authorization: (optional) the default authorization file for user public keys
