There are a few ways of becoming an admin for a CoBox seeder.
When following the setup a seeder an initial admin is setup.
Once you have installed the seeder you can generate an invite code to add friends (or your own devices) as an admin for this seeder.
cobox-seeder invites create <cobox-address>
Doing so will add them as a superuser to this seeder, with the same powers as the original admin. Doing so will mean the seeder can be remote controlled from within the CoBox App.
Once the invite code has been received there are two ways to use the code.
The Seeder Admin interface can be accessed in
Settings > Seeders. Click the
+ icon and then paste the invite code in the corresponding section.
From the app CLI you can issue the following command:
cobox seeders up --code <code>
