Thanks Mark, I will try that out. I think I tried doing it before and I wasn’t having much success with the broadcast address but I understand a bit more about EPICs not so I can hopefully debug if its something else.
This does lead me three other questions though
1) If I have multiple addresses I need to list in EPICS_CA_ADDR_LIST
Is the proper way EPICS_CA_ADDR_LIST=[192.168.1.255 192.168.2.255]?
2) I am wondering if I have multiple IOCs running on my linux machine do I need to then start to worry about starting up the CARepeater if I use the broadcast addressing?
3) If I have multiple subnets such as above 192.168.1.x and 192.168.2.x, will I run into issues if I don’t setup cagateways or am I misunderstanding there use?
Thanks,
Adam

It is because you have more than one network interface and you are running the IOC and client on the same machine.
You can set EPICS_CA_AUTO_ADDR_LIST=NO and EPICS_CA_ADDR_LIST to the broadcast address of one of the interfaces.

Hey All,
Having a weird issue where I try to run a very simple IOC with a few analog out records and getting CA.Client.Exception
Warning: Identiical Process variable names on multiple servers
Context: Channel calc:a connecting to ubuntu:5064 ignored: localhost:5064
Ubuntu is my hostname on this VM and this is the first time I have encountered this when just running a single IOC.
Thanks
