Hey Marcio,
one think that comes to my mind: If you run the IOCs in
containers with network mode host there might be multiple
caRepeaters now listening on the same IP address and ports as each
IOC might start its own caRepeater within its container.
If you start multiple IOC on the same host without containers
there will be only one instance of the caRepeater process.
I'm not sure if this might cause your problem.
Best regards,
Florian

This is the scenario:
In HostA I have one container running an IOC and another
container with caget/caput installed. Both containers have these
env variables defined:
EPICS_CA_ADDR_LIST=127.255.255.255
EPICS_CA_REPEATER_PORT=5065
EPICS_CA_SERVER_PORT=5064
I can caget in one container and receive data from the IOC.
When both are in the same host it works well. With tcpdump I can see the traffic between the
two containers, using localhost to communicate.
The containers are running with network host mode.
Now I want to run caget in HostB that is in a different
network. In HostB I've defined:
EPICS_CA_ADDR_LIST=134.79.219.255
EPICS_CA_REPEATER_PORT=5065
EPICS_CA_SERVER_PORT=5064
With tcpdump in HostA, I can see that 5 caget
requests arrive from HostB to HostA, but the IOC doesn't
seem to be aware of the packages. I understand that the IOC
responds to broadcast requests coming from any of the
interfaces by default. Is that right?
Any clues? If you need more data, I'm happy to add them to this
thread.
Thank you,
