Hi Evan,

I have just restarted a set of IOCs after puppetizing their configuration. They are accessible via a Telnet ProcServ connection, and dbpf shows everything populated and defined. However, if I try to use caget, caput, etc. there is no connection. What are the possible causes of this? EPICS_CA_AUTO_ADDR_LIST seems to be set as “YES” and other IOCs I haven’t touched are still reachable.

Is Puppet running them inside a container? If so you need to configure that to share the host’s network (or run a CA Gateway between the host’s network and the internal container network, but I don’t really recommend doing that).

The iocsh command ‘casr 1’ will show you what the network interfaces are that the CA server is listening on and sending beacons to.
