Hi,

Give this a try:

Before you start medm (or any CA client) set the EPICS_CA_ADDR_LIST like
so:
=========================================================================
export EPICS_CA_ADDR_LIST="<linux-ip-number>:5064  <linux-ip-
number>:5066"
=========================================================================

So, bascially the EPICS CA address list can contain a list of space
delimited entries in <IP>:portnumber format.

Thanks,
