SSH Tectia

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.

      Writable to root (should). Readable to world.

    • /etc/ssh2/random_seed: the seed file for the random number generator

    • /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/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"/>.

  • $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
