Description: `Manage the access control list for the ntfy server.
|
|
|
|
This is a server-only command. It directly manages the user.db as defined in the server config
|
|
file server.yml. The command only works if 'auth-file' is properly defined. Please also refer
|
|
to the related command 'ntfy user'.
|
|
|
|
The command allows you to show the access control list, as well as change it, depending on how
|
|
it is called.
|
|
|
|
Usage:
|
|
ntfy access # Shows access control list (alias: 'ntfy user list')
|
|
ntfy access USERNAME # Shows access control entries for USERNAME
|
|
ntfy access USERNAME TOPIC PERMISSION # Allow/deny access for USERNAME to TOPIC
|
|
|
|
Arguments:
|
|
USERNAME an existing user, as created with 'ntfy user add', or "everyone"/"*"
|
|
to define access rules for anonymous/unauthenticated clients
|
|
TOPIC name of a topic with optional wildcards, e.g. "mytopic*"
|
|
PERMISSION one of the following:
|
|
- read-write (alias: rw)
|
|
- read-only (aliases: read, ro)
|
|
- write-only (aliases: write, wo)
|
|
- deny (alias: none)
|
|
|
|
Examples:
|
|
ntfy access # Shows access control list (alias: 'ntfy user list')
|
|
ntfy access phil # Shows access for user phil
|
|
ntfy access phil mytopic rw # Allow read-write access to mytopic for user phil
|
|
ntfy access everyone mytopic rw # Allow anonymous read-write access to mytopic
|
|
ntfy access everyone "up*" write # Allow anonymous write-only access to topics "up..."
|
|
ntfy access --reset # Reset entire access control list
|
|
ntfy access --reset phil # Reset all access for user phil
|
|
ntfy access --reset phil mytopic # Reset access for user phil and topic mytopic
