Duplicate Device Issue

[lja-commits]

We are maxing out our device limit (2500) due to device being duplicated when they are rebuilt.

Our custom client uses the allow-hostname-as-id=Y setting.
When the device is initially built, an entry is created in the device list with an ID that is a preset/fixed hostname (HOSTNAME1234).

When the device is rebuilt, it goes back into the device list with the default RustDesk ID (1680798129) instead of the hostname.
The hostname remains in the list, but that device entry is offline. The online device is the new entry with the default DustDesk ID (1680798129).
The allow-hostname-as-id=Y setting seems to fail due to the device ID (hostname) already existing.

The hostname is still visible under the device column (username@device_name) but the issue is the duplicated/maxing out the device limit.

We are currently running on RustDesk Server Pro 1.7.7 at the moment.

This can happen when the operating system is rebuilt, or when the RustDesk configuration files are deleted or not preserved. Are you experiencing either of these two situations?

rustdesk/rustdesk#14200

If the configuration files are deleted, RustDesk generates a new public key (PK). If the server also sees the reinstalled client connecting from a different IP address during the same registration, it may identify it as a different device.

Since HOSTNAME1234 is already associated with the previous device identity, the reinstalled client cannot reuse that ID and is assigned a newly generated numeric ID instead.

The operating system is being rebuilt which will delete the RustDesk config files. The IP will most likely be different during the point of registration.

Is there a solution to this beyond manually deleting the device from RustDesk before every single rebuild of the operating system?

beyond manually deleting the device from RustDesk before every single rebuild of the operating system

This is currently the simplest and most straightforward solution in this situation.
