Chris,
You need a beacon anomaly that your clients can see, so they rebroadcast
their unresolved names.
Quick-and-dirty solution:
The easiest way to create a beacon anomaly is to start up an IOC. Create
an empty soft IOC on a machine on the clients' network (the softIoc
executable from base is fine). Set up a cron job that starts the IOC,
waits a second, then kills it.
Whenever that cron job runs, all clients on the local network will try
to resolve their channels.

I want to be able to force my EPICS channel access client to begin a

listening to the channels won't see a beacon anomaly and begin the
channel search sequence.
I can see a couple of ways to do this.
- Send a network beacon to the CA Repeater.
- Issue a search for some non-existent channel.
Please advise on what is a good way to do this. Example code or
references to EPICS source code are very welcome, as I am neither
familiar with EPICS base software, nor am I an experienced network
programmer. My client software uses EPICS 3.13.10.
