netperf -H <server_ip> -p 12865 -v 2 -t NULL Look for the line: Netperf server on <server_ip>: netserver revision x.x.x . This confirms the exact version. Manually verifying 20 servers is tedious. Here is a bash script that automates verification and outputs a clean, verified list in CSV format.
Save as verify_netperf_servers.sh :
| Hostname / IP | Port | Netperf Version | Location | Capabilities (Tests) | Last Verified | | :--- | :--- | :--- | :--- | :--- | :--- | | netperf-east.example.com | 12865 | 2.7.0 | AWS us-east-1 | TCP_STREAM, UDP_RR | 2025-01-15 | | 192.168.1.100 | 12866 | 3.7.0 (git) | Local Lab | ALL (incl. SCTP) | 2025-01-20 | | `public.netperf.planet | 12865 | 2.6.0 | Europe (FRA) | TCP_STREAM only | 2024-12-01 | netperf server list verified
nc -zv <server_ip> 12865 Expected output: Connection to <server_ip> port 12865 [tcp/*] succeeded! The most reliable verification is a minimal, low-impact Netperf test that confirms the daemon is responsive. netperf -H <server_ip> -p 12865 -v 2 -t
