What This Tool Checks

The TLS certificate tool opens a bounded TLS handshake and reports subject, issuer, validity dates, days remaining, and alternative names when available.

When To Use It

Use it when users see certificate warnings, after renewing a certificate, or before switching a hub to NMDCS or ADCS.

Why It Helps Hub Owners

Secure Direct Connect endpoints need reachable TLS and a certificate that matches the hostname clients use.

What To Check

  • Expired certificates can make secure clients refuse the hub.
  • Name mismatch often happens when a certificate does not include the hub hostname.
  • Some hubs use custom certificates; review client expectations before changing TLS settings.

Hub TLS Certificate Tool

Inspect the certificate returned by a public TLS-enabled hub or web endpoint.

Enter a public hostname, IP address, or hub-style address such as dchub://example.com:411.
Enter a TCP port from 1 to 65535.

Related Hub Tools

Add Your DC Hub To The Public DC++ Hublist

Submit a public Direct Connect hub for hourly checks, searchable indexing, and inclusion in the public NMDC, NMDCS, ADC, and ADCS hublist files.

 Hub Ping Tool

Test whether a public DC++ or Direct Connect hub hostname responds to ICMP ping, then review packet loss, latency, and DNS resolution.

 Hub WHOIS Tool

Look up public WHOIS, registrar, domain, and network ownership information for Direct Connect hub hostnames and IP addresses.

 Hub DNS Dig Tool

Run dig-style DNS checks for Direct Connect hub hostnames and inspect A, AAAA, CNAME, MX, NS, SOA, and TXT records.

 Hub DNS Overview Tool

Review A, AAAA, CNAME, MX, NS, SOA, and TXT records for public Direct Connect hub hostnames from the hublist server.

 Hub Reverse DNS Tool

Check reverse DNS PTR hostnames for public IP addresses used by Direct Connect and DC++ hubs.

 Hub TCP Connect Tool

Test whether a specific public Direct Connect TCP port accepts connections from the hublist server for NMDC, NMDCS, ADC, and ADCS hubs.

 Hub Protocol Test Tool

Test whether a public DC++ hub endpoint accepts dchub, NMDC, NMDCS, ADC, or ADCS connections from the hublist server.

 Hub Traceroute Tool

Trace the network path from the hublist server to a public Direct Connect hub hostname or IP address for routing diagnostics.

 Hub Port Scan Tool

Run a bounded public TCP check against common Direct Connect hub ports and see which NMDC, NMDCS, ADC, or ADCS ports appear reachable.
