Beacons fixed, thanks.

Trying multicast name resolution:

tux$ EPICS_CAS_INTF_ADDR_LIST='0.0.0.0 224.0.2.9' EPICS_CA_ADDR_LIST=224.0.2.9 EPICS_CA_AUTO_ADDR_LIST=NO bin/linux-x86_64/softIoc -x anj
Starting iocInit

CAS address list can not contain 0.0.0.0 and other addresses, ignoring...
iocRun: All initialization complete
epics>

I get the same output from 'casr 2' without the warning message by omitting the 0.0.0.0 interface address, so I'll assume including it was just a mistake in your instructions above.

Searches from the same subnet succeed with EPICS_CA_ADDR_LIST=224.0.2.9 EPICS_CA_AUTO_ADDR_LIST=NO. Do I need to have our network admins configure something for searches to work across subnets? They don't for me at the moment using the same unmodified 3.14-based client. This was only an experimental feature though so it's not a blocker at all.

If I configure the IOC to only use the localhost interface, why does it still send beacons through my primary interface?

I had expected that explicitly setting the interface would also configure the beacons to be sent through the same interface(s), although I do realize the original code didn't work like that and it can be done manually. I'd be OK with leaving that change for later if there are objections to fixing it here though.

I also have some minor modifications to casr which I'll finish off next week.
