John,
You might find that it is easier to add the following to your startup
script (before iocInit is called):
putenv("EPICS_CA_ADDR_LIST = 128.84.44.84 192.168.213.148")
Alternatively, you might try quotes around the IP addresses in the
resource.def as follows:
EPICS_CA_ADDR_LIST DBF_STRING "128.84.44.84 192.168.213.148"
I seem to vaguely recall that this also works.
