RKR SETU 1.0 : Build it, Run it, Manage it.

Last time we built it. This time we switch it on, and things break like they do on any live floor.

Imagine every issue identified and understood in seconds. That's what we're building with SETU 1.0.

For the ops teams, techs and electricians who keep data centres running.

There are 15 incidents in this video. How many have you experienced?

At RKR Networks, we've published a security guide to help network and system admins protect networked refrigeration controllers, with practical steps and checks.

Please feel free to share it with anyone who manages these systems.

Here's the full landscape behind today's AN-L1 news. Ten vendors, eleven capabilities, public sources only.

We model the network end to end, and go beyond it.

Today we are glad to announce that RKR Networks · SETU is AN-L1.

SETU models your network, and goes beyond it: firewalls, power, cabling and RF, across every vendor. One synthetic twin, end to end.

AN-L1 is our own measurement on the TM Forum scale.

RKR Podcast, Episode 13: No floor plan? Build one.

A host with no drawings asks where the Wi-Fi signal goes. We build the floor in RKR RF Bench, place access points, then walk the same floor spot by spot.

Build the floor first, then let the walls tell you where the signal goes.

No floor plan? Build one.

RKR RF Bench lets you draw a plan, place APs, and see coverage, open for anyone to learn.

RKR Podcast, Episode 12: No drawings. Send what you have.

A building with nothing written down. Drop what you have, photos, a spreadsheet, configs, and SETU builds the synthetic twin. One site, 419 devices, no floor plans. Log in to a device. Ping from a desk and see the exact path.

Send what you have. SETU builds the synthetic twin.

There are not enough cyber experts/beginners in enterprises to carry this out. At some point, all vendors need to convene together, cyber, networking, server/compute and sit together and figure out the future.

Network/Security Infra is the most at risk, liability or not, we have to help customers. There is no other way.

RKR Podcast, Episode 11: Three routes, one last cable.

Three routes to the reception desk, and all three end on switch two. Lose it and 52 ports and 18 cables go dark, and 10 hosts can't be reached.

Count redundancy all the way to the device.

RKR Podcast, Episode 9: Six devices lost power, six floors went dark.

One failed rising main puts six closet UPS units on battery. One question finds the root in 15 seconds. When the batteries run out, 6 devices lose power and 95 of 280 go offline.

RKR Podcast, Episode 8: Full bars at seven, unusable at eleven.

Same desk, same strong signal, yet a new laptop drops from 178.7 Mbps at 7 to 1.29 Mbps at 11. The access point ran out of airtime.

@poteto can we increase the storage on the grok bots computer?

RKR Podcast, Episode 7: Break it here, not on the floor.

One switch port taken down on purpose, the access point on it gone dark, and its cable traced in the RKR SETU GUI: Cable 002, 34.6 metres. Then the fix, tried in the synthetic twin first.

RKR Podcast, Episode 6: One breaker away.

One busway out for maintenance, and the check says nothing loses power. RKR SETU asks what one more breaker would do in a synthetic twin: 5 devices lose power, 4 servers go down, 32 GPUs drop out.

FYI

[RKR Networks @rkrnetworks]

Security advisory: Linux kernel TCP flaw CVE-2026-98432 (CVSS 9.8).

A remote attacker can crash a Linux server, or take it over, with no login. Kernels 4.4+ are affected. Ubuntu and RHEL had no fix yet on Nov 1.

Patch and reboot. Until then, use the firewall rule in section 3.

RKR Podcast, Episode 5: One deny line, 289 flows.

RKR SETU rehearses two reviewed changes against 503 flows in a synthetic twin. Half the route withdrawal was a failover, and one deny line blocks 289 flows.

[RKR Networks @rkrnetworks]

Yes, there's a GUI.

A full synthetic twin of a multi-floor building.
Inject a fault: a switch port goes down. Simulated.
Right-click the AP. Trace its cable to the exact switch port, with length.
Try the fix in the synthetic twin first.

Break it here, not on the floor.

@anandmahindra Is it possible to bring back the 2011-12 design for scorpio?

[Ravipati Ajay Kumar @RavipatiAj]

200+ integrations for RKR SETU. Proud of the team.

[RKR Networks @rkrnetworks]

200+ integrations. One synthetic twin.

RKR SETU integrates read-only by default with 200+ platforms across network, cloud, compute, IoT, buildings, security and IT, and brings what they hold into the synthetic twin.

The company that still finds ways to employ a majority of the human workforce post AI will win.
