Hi All,
I have multiple servers, each running multiple IOCs (EPICS base 3.14.12.3), and each connected to two networks: the local lab network, and the site network. In an ideal world, I would like to have read-write access to PVs from any machine within the lab network, but read-only access from the site network. In a test environment, I've seen I should be able to do this by running a gateway on a dedicated machine connected to both networks, and with no IOCs running on it, and disconnecting all other servers from the site network. Fair enough, I have one solution, but having a dedicated server for the gateway seems a big waste... Is there any way of setting up the servers so that by default they don't broadcast any PV to the site network? And then on top of that, could I have a gateway running on one of them (with some IOCs running on that server too) when I want to give read-only access to the site network? I've looked into tech-talk, and found quite a few old threads related to this, but it looks like it's not possible. Is that still the case? The documentation for R3.14 talks about EPICS_CAS_INTF_ADDR_LIST, which should do the job, but it also says it's not implemented in R3.14 and previous releases...! Cheers, Isabella
