Technical Details

what runs on :1043

BOINC client control is an RPC interface used by the BOINC Manager and other management tools. The control protocol is normally carried over TCP using framed XML-style requests and responses, with authentication based on the client's GUI RPC password; the registry assignment lists both TCP and UDP, although routine client-control traffic is generally TCP. The commonly documented default control port is TCP 31416, while 1043 may be used when configured or by older deployments.

security overview

The interface can expose administrative control over a BOINC client, including changing projects and controlling computation. It is not encrypted by default and should normally be restricted to localhost or trusted management hosts; do not expose it directly to the internet.

Record

iana registry entry

port: :1043
service: BOINC Client Control
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: System
usage: This port is assigned for BOINC Client Control, allowing BOINC management software to communicate with a running client. BOINC deployments commonly use the client control interface on TCP 31416, so port 1043 is likely a legacy or explicitly configured alternative rather than the usual default.
