As explained in Discovering Wiretap Servers, to distinguish between the multiple Wiretap servers that often co-exist on the same host, Wiretap server IDs consist of two parts: the host machine and the type of database it exposes. Backburner Wiretap servers follow the same naming convention.
Since Backburner databases are always named Backburner, the full specification for a Backburner server is hostname:Backburner. For example, if the Wiretap server is montreux, the associated Backburner server is discoverable as montreux:Backburner.
For example, issuing the following command from the command line lists only the Backburner Wiretap servers on the network:
wiretap_server_dump -d Backburner
