Multiple Soft IOCs on one host (same subnet)Tip automatically create/delete an iptables rule that replaces the destination address of all incoming CA UDP traffic on each interface with the broadcast address of that interface. Drop/link the following script into /etc/network/if-up.d/ and /etc/network/if-down.d/. #!/bin/sh -e
# Called when an interface goes up / down
# Author: Ralph Lange <[email protected]>
# Make any incoming Channel Access name resolution queries go to the broadcast address
# (to hit all IOCs on this host)
# Change this if you run CA on a non-standard port
PORT=5064
[ "$METHOD" != "none" ] || exit 0
[ "$IFACE" != "lo" ] || exit 0
line=`ip addr show $IFACE`
addr=`echo $line | grep -Po 'inet \K[\d.]+'`
bcast=`echo $line | grep -Po 'brd \K[\d.]+'`
[ -z "$addr" -o -z "$bcast" ] && return 1
if [ "$MODE" = "start" ]
then
iptables -t nat -A PREROUTING -d $addr -p udp --dport $PORT -j DNAT --to-destination $bcast
elif [ "$MODE" = "stop" ]
then
iptables -t nat -D PREROUTING -d $addr -p udp --dport $PORT -j DNAT --to-destination $bcast
fi
exit 0Caution Note: This will not work for clients on the same host. (Adding that feature makes things a lot more complicated, and I like things to be simple.) If you need connections between IOCs on one host, I would suggest adding the broadcast address of the loopback interface (usually 127.255.255.255) to each IOC’s EPICS_CA_ADDR_LIST setting. export EPICS_CA_ADDR_LIST=127.255.255.255
export EPICS_PVA_ADDR_LIST=127.0.0.1
export EPICS_CA_AUTO_ADDR_LIST=no
export EPICS_PVA_AUTO_ADDR_LIST=no
