Hello,

 

I’m working on a new facility where EPICS has just been setup, and I’ve booted an EPICS IOC, which is up and running. The IOC a power supply controller which has a cpu. We’re running a diskless boot of linuxRT on this cpu and starting an EPICS ioc on this remove cpu.  I see the ioc running on this remove CPU and I can connect to this IOC, and use dbpr and dbpf to read and set pvs on the ioc. However, from the server, with the new EPICS infrastructure, I don’t have anyCA connection to the IOC, even though the ioc and server are on the same subnet.  I suspect some environment variable is not setup correctly,  but I simply can’t see the problem and need some expert help.
