RSRV now honors EPICS_CAS_INTF_ADDR_LIST and binds to only +the provided list of network interfaces. Name searches (UDP and TCP) on other network interfaces are ignored. For example on a computer with interfaces 10.5.1.1/24, 10.5.2.1/24, and 10.5.3.1/24, setting "EPICS_CAS_INTF_ADDR_LIST='10.5.1.1 10.5.2.1'" will accept traffic on the .1.1 and .2.1, but ignore from .3.1

libca, RSRV, and PCAS may now use IPv4 multicasting for UDP traffic (name search and beacons). This is disabled by default. To enable multicast address(s) must be listed in EPICS_CA_ADDR_LIST for clients and EPICS_CAS_INTF_ADDR_LIST for servers (IOCs should set both). -For example: "EPICS_CAS_INTF_ADDR_LIST='0.0.0.0 224.0.2.9' EPICS_CA_ADDR_LIST=224.0.2.9". +For example: "EPICS_CAS_INTF_ADDR_LIST='224.0.2.9' EPICS_CA_ADDR_LIST=224.0.2.9".
Please note that no IPv4 multicast address is officially assigned for Channel Access by IANA. diff --git a/src/ioc/rsrv/caservertask.c b/src/ioc/rsrv/caservertask.c index 605f08cc6..1ee02b723 100644 --- a/src/ioc/rsrv/caservertask.c +++ b/src/ioc/rsrv/caservertask.c @@ -1,4 +1,7 @@ /*************************************************************************\ +* Copyright (c) 2016 Michael Davidsaver +* Copyright (c) 2015 Brookhaven Science Assoc. as operator of Brookhaven +* National Laboratory. * Copyright (c) 2002 The University of Chicago, as Operator of Argonne * National Laboratory. * Copyright (c) 2002 The Regents of the University of California, as
