Hi everyone
We use a PXIe-Chassis (PXIe-1088) with a PXIe-8880 Controller where we want to run a custom TCP communication (some simple JSON commands) via NI VeriStand (which runs on the PXIe as well as on the Host) to a Windows PC (which could be also the Host or some other PC). The Custom Device runs well, and we can communicate if we have a direct ethernet communication. Our IT(-Crowd) says that the don’t have any firewall in our lab so there must be some additional specific configuration needed on the NI Hardware (or maybe as well on the Host). However, we tried to open the ports on the PXIe-8880 (NI RT Linux) over iptables but I look like it had no effect. We also opened the ports on the Windows PC. Does somebody run something similar and can help us with that?
Setup:
- Windows PC:
- OS: Windows 10
- Open Ports: 3333 and 60000 (for in and outgoing)
- TCP Server: Simple LabVIEW TCP Server or a custom-made Python TCP Server based on Tornado
- LabVIEW and Veristand Version: 21 64-bit
- PXIe:
- OS: NI Linux Real-Time x64 5.10.106-rt64
- Open Ports: 3333 and 60000 (for in and outgoing)
- TCP Client: NI VeriStand Custom Device with basic TCP VI’s
Again, the whole software looks like working since it will work as long, we connect both systems directly with an ethernet cable! So for me it still sounds like a problem on our IT-Side but it's quite hard to argue for me 🙂
If needed/wanted I can add the custom device as well as our API or the PXIe-Configuration.
I’m very grateful for any help!!!
Cheers
Christian
