Experimental Physics and Industrial Control System
Thanks Han,
Will I need to just drop the script on the system that is running the multiple IOCs? Also do I keep the EPICS_CA_ADDR_LIST env variable on client/server with the broadcast address 192.168.1.255/192.168.2.255 respectively once I have added that script on the server?

Hi Adam,
Please look at the following document, which Ralph prepared, and I updated "slightly"
https://urldefense.us/v3/__https://epics-controls.org/resources-and-support/documents/howto-documents/channel-access-reach-multiple-soft-iocs-linux/__;!!G2kpM7uM-TzIFchu!iWAkPmEMaKK8Pxy2rfbP9icXJMW10JgvWCEsVuESZZ0kBS5_DT4I6cPBTNYTFMAXM2Os$
And here is my own old tool which you may use for fun.

Currently I start up 4-5 IOCs on my linux host but depending on the order my client cant access one of the IOCs, the host/client are on different subnets 192.168.1.X/192.168.2.X respectively. I had a previous post where it was brought up that I should be able to add in the EPICS_CA_ADDR_LIST the broadcast address on the IOCs and on the client trying to connect to one of the IOCs on the linux host. For example 192.168.1.255 (client broadcast) and 192.168.2.255 (host broadcast), I keep EPICS_CA_AUTO_ADDR=YES. But once I change the env variables to have the broadcast IPs, I am not able to caget on the client to any of the IOC PVs running on the linux host. Ports are open, no firewall rules.
