GENERAL INFORMATION
turnadmin is a TURN administration tool. This tool can be used to manage the user accounts
(add/remove users, generate TURN keys for the users). For security reasons, we do not
recommend storing passwords openly. The better option is to use pre-processed "keys" which
are then used for authentication. These keys are generated by turnadmin. Turnadmin is a
link to turnserver binary, but turnadmin performs different functions.
Options note: turnadmin has long and short option names, for most options. Some options
have only long form, some options have only short form. Their syntax somewhat different,
if an argument is required:
The short form must be used as this (for example):
$ turnadmin -u <username> ...
The long form equivalent must use the "=" character:
$ turnadmin --user=<username> ...
If this is a flag option (no argument required) then their usage are the same, for
example:
$ turnadmin -k ...
is equivalent to:
$ turnadmin --key ...
You have always the use the -r <realm> option with commands for long term credentials -
because data for multiple realms can be stored in the same database.

NAME
turnadmin - a TURN relay administration tool.
SYNOPSIS
$ turnadmin [command] [options]
$ turnadmin [ -h | --help]
DESCRIPTION
Commands:
-P, --generate-encrypted-password
Generate and print to the standard output an encrypted form of a password (for web
admin user or CLI). The value then can be used as a safe key for the password
storage on disk or in the database. Every invocation for the same password produces
a different result. The for mat of the encrypted password is:
$5$<...salt...>$<...sha256(salt+password)...>. Salt is 16 characters, the sha256
output is 64 characters. Character 5 is the algorithm id (sha256). Only sha256 is
supported as the hash function.
-k, --key
Generate key for a long-term credentials mechanism user.
-a, --add
Add or update a long-term user.
-A, --add-admin
Add or update an admin user.
-d, --delete
Delete a long-term user.
-D, --delete-admin
Delete an admin user.
-l, --list
List long-term users in the database.
-L, --list-admin
List admin users in the database.
-s, --set-secret=<value> Add shared secret for TURN RESP API
-S, --show-secret
Show stored shared secrets for TURN REST API
-X, --delete-secret=<value> Delete a shared secret.
--delete-all_secrets
Delete all shared secrets for REST API.
-O, --add-origin
Add origin-to-realm relation.
-R, --del-origin
Delete origin-to-realm relation.
-I, --list-origins
List origin-to-realm relations.
-g, --set-realm-option
Set realm params: max-bps, total-quota, user-quota.
-G, --list-realm-options
List realm params.
-E, --generate-encrypted-password-aes
Generate and print to the standard output an encrypted form of password with
AES-128
Options with required values:
-b, --db, --userdb
SQLite user database file name (default - /var/db/turndb or
/usr/local/var/db/turndb or /var/lib/turn/turndb). See the same option in the
turnserver section.
-e, --psql-userdb
PostgreSQL user database connection string. See the --psql-userdb option in the
turnserver section.
-M, --mysql-userdb
MySQL user database connection string. See the --mysql-userdb option in the
turnserver section.
-J, --mongo-userdb
MongoDB user database connection string. See the --mysql-mongo option in the
turnserver section.
-N, --redis-userdb
Redis user database connection string. See the --redis-userdb option in the
turnserver section.
-u, --user
User name.
-r, --realm
Realm.
-p, --password
Password.
-x, --key-path
Generates a 128 bit key into the given path.
-f, --file-key-path
Contains a 128 bit key in the given path.
-v, --verify
Verify a given base64 encrypted type password.
-o, --origin
Origin
--max-bps
Set value of realm's max-bps parameter.
--total-quota
Set value of realm's total-quota parameter.
--user-quota
Set value of realm's user-quota parameter.
-h, --help
Help.

$ turnadmin --redis-userdb="<db-connection-string>" -o <origin>
List all origin-to-realm relations in Redis DB:
$ turnadmin --redis-userdb="<db-connection-string>" -I
List the origin-to-realm relations in PostgreSQL DB for a single realm:
$ turnadmin --psql-userdb="<db-connection-string>" -I -r <realm>
Create new key file for mysql password encryption:
$ turnadmin -E --key-path <key-file>
Create encrypted mysql password:
$ turnadmin -E --file-key-path <key-file> -p <secret>
Verify/decrypt encrypted password:
$ turnadmin --file-key-path <key-file> -v <encrypted>
