CAN and SocketCAN
Share supported CAN interfaces and work with familiar Linux CAN workflows.
Automotive diagnostics
Bring the vehicle test bench to the engineer
Reserve an automotive interface, run approved diagnostic work close to the vehicle, and give remote specialists the access they need without giving away the whole lab.
What you can do
Built around the job, not the jargon
J2534 pass-thru
Provide a controlled session for supported pass-thru tooling and retain it across related operations.
UDS diagnostics
Run approved diagnostic services and keep structured request, response, and timing traces.
DoIP activation
Prepare an authorized diagnostics-over-IP connection for suitable vehicle and bench networks.
Guarded ECU programming
Use a staged programming workflow with permission checks, progress stages, verification, and a recorded outcome.
Lease-based safety
Every operation requires an active reservation for the exact resource; view-only access cannot perform control actions.
A clear workflow
From invitation to completed work
- 1
Reserve the interface
Choose the CAN, J2534, or DoIP resource assigned to the job.
- 2
Run approved diagnostics
Use the permitted services and retain structured traces.
- 3
Release safely
Close the session, return the resource to availability, and preserve the activity record.
Common questions
Good to know
Does NullPort support SocketCAN?
Yes. SocketCAN is represented in the Linux and embedded automotive workflow.
Can view-only users program an ECU?
No. Observe-only reservations are rejected for control and programming actions.
Is physical interface compatibility universal?
No. Hardware support depends on the specific CAN or J2534 device and its platform driver. Confirm the target setup during evaluation.
