Check a short, explicit list of public TCP ports used by a DC++ or Direct Connect hub without running a broad network scan.
Purpose
The tool makes bounded TCP connection attempts to the submitted public host and port list, then reports each port as open or closed with timing and error context.
When To Use It
- Compare the ports published for NMDC, NMDCS, ADC, or ADCS.
- Check firewall, NAT, or VPS security-group changes.
- Confirm that an old listener closed after a protocol or port migration.
Reading The Results
An open row means a TCP socket was accepted from the hublist server. A closed or timed-out row points to no listener, filtering, routing, or forwarding trouble. Test the advertised hub port first.
Limitations
This is a bounded hub-port checker, not a vulnerability scanner. An open socket does not identify the service or prove a valid Direct Connect handshake. Only public targets and the limited submitted port set are accepted.
