TabPy Server Configuration Instructions

Default settings for TabPy may be viewed in the tabpy_server/common/default.conf file. This file also contains commented examples of how to set up your TabPy server to only serve HTTPS traffic and enable authentication.

Change settings by:

  1. Adding environment variables:
    • set the environment variable as required by your Operating System. When creating environment variables, use the same name as is in the config file as an environment variable. The files startup.sh and startup.cmd in the root of the install folder have examples of how to set environment variables in both Linux and Windows respectively. Set any desired environment variables and then start the application.
  2. Modifying default.conf.
  3. Specifying your own config file as a command line parameter.

    • i.e. Running the command:

      python tabpy.py --config=path\to\my\config

The default config file is provided to show you the default values but does not need to be present to run TabPy.

Configuring HTTP vs HTTPS

By default, TabPy serves only HTTP requests. TabPy can be configured to serve only HTTPS requests by setting the following parameter in the config file:

TABPY_TRANSFER_PROTOCOL = https

If HTTPS is selected, the absolute paths to the cert and key file need to be specified in your config file using the following parameters:

TABPY_CERTIFICATE_FILE = C:/path/to/cert/file.crt
TABPY_KEY_FILE = C:/path/to/key/file.key

Note that only PEM-encoded x509 certificates are supported for the secure connection scenario.

Authentication

TabPy supports basic access authentication (see https://en.wikipedia.org/wiki/Basic_access_authentication for more details).

Enabling Authentication

To enable the feature specify the TABPY_PWD_FILE parameter in the TabPy configuration file with a fully qualified name:

TABPY_PWD_FILE = c:\path\to\password\file.txt

Password File

Password file is a text file containing usernames and hashed passwords per line separated by single space. For username only ASCII characters are supported.

It is highly recommended to restrict access to the password file with hosting OS mechanisms. Ideally the file should only be accessible for reading with the account under which TabPy runs and TabPy admin account.

There is a utils/user_management.py utility to operate with accounts in the password file. Run utils/user_management.py -h to see how to use it.

After making any changes to the password file, TabPy needs to be restarted.

Adding an Account

To add an account run utils/user_management.py utility with add command providing user name, password (optional) and password file:

python utils/user_management.py add -u <username> -p <password> -f <pwdfile>

If the (recommended) -p argument is not provided a password for the user name will be generated and displayed in the command line.

Updating an Account

To update the password for an account run utils/user_management.py utility with update command:

python utils/user_management.py update -u <username> -p <password> -f <pwdfile>

If the (recommended) -p agrument is not provided a password for the user name will be generated and displayed in the command line.

Deleting an Account

To delete an account open password file in any text editor and delete the line with the user name.
