|
|
# EPICS_CAS_INTF_ADDR_LIST - list of IP addresses identifying
|
|
# a limited set of network interfaces for server communication.
|
|
# Specifically, this parameter specifies the interfaces from
|
|
# which the server will accept TCP/IP connections. It also
|
|
# specifies that UDP search messages addressed to both
|
|
# the IP addresses in EPICS_CAS_INTF_ADDR_LIST and also
|
|
# the broadcast addresses (or the destination addresses of
|
|
# point to point interfaces) of the corresponding interfaces
|
|
# will be accepted by the server. If this parameter is empty
|
|
# then TCP/IP connections are accepted from any interface
|
|
# (and any search messages addressed to the host are accepted).
|
|
# Beacons are sent only to the broadcast address of each interface
|
|
# in this list (or the destination address of point to point
|
|
# interfaces) if EPICS_CA_AUTO_ADDR_LIST is YES.
|
|
# Type "ifconfig -a" in order to determine which interfaces
|
|
# are available.
|
|
# EPICS_CAS_BEACON_ADDR_LIST - If this parameter is specified
|
|
# or if EPICS_CAS_INTF_ADDR_LIST isnt empty then this parameter
|
|
# is used instead of EPICS_CA_ADDR_LIST by the server library
|
|
# to augment the list of addresses to send beacons to.
|
|
# EPICS_CAS_SERVER_PORT - If this parameter is specified then it
|
|
# and not EPICS_CA_SERVER_PORT is used to determine the server's
|
|
# port number. It is possible to have multiple servers on the
|
|
# same host on the same EPICS_CAS_SERVER_PORT port if the IP
|
|
# kernel is modern (if it has multicast enhancements). In this
|
|
# situation all servers will share the same user specified
|
|
# UDP port number and will be assigned unique TCP port numbers.
|
|
# The fact that the servers may not be using the user specified
|
|
# port number for TCP will be completely transparent to EPICS
|
|
# 3.13 or higher clients that will be locating the servers
|
|
# using the user specified UDP port number, but will be connecting to
|
|
# the servers using whatever TCP port has been assigned.
|
|
#
|
|
# If experiencing trouble getting clients to connect
|
|
# --------------------------------------------------
|
|
#
|
|
# o Make sure that the broadcast addresses are identical on the
|
|
# server's host and on the client's host. This can be checked with
|
|
# "netstat -i" or "ifconfig -a".
|
|
#
|
|
# o Make sure that the client and server are using the same UDP
|
|
# port. Check the server's port by running "netstat -a | grep nnn"
|
|
# where nnn is the port number involved. If you do not set
|
|
# EPICS_CA_SERVER_PORT or EPICS_CAS_SERVER_PORT
|
|
# then the default port will be 5064.
|
|
#
|
|
# o Two servers can run on the same host with the same server port number
|
|
# if the following restrictions are understood (good luck). If the host has a
|
|
# modern IP kernel it is possible to have two servers on the same UDP port.
|
|
# It is not possible for two servers to run on the same host using the same
|
|
# TCP IP server port. If the CA server library detects that a 2nd server is attempting
|
|
# to start on the same port as an existing CA server then both servers will use the
|
|
# same UDP port if it is a modern IP kernel, and the 2nd server will
|
|
# be allocated a new TCP port. In this situation the clients will still be
|
|
# configured to use the same port number for both servers. The clients
|
|
# will find the 2nd server via the shared UDP port, and transparently
|
|
# connect to the 2nd server's allocated TCP port. Be aware that If there are
|
|
# two server's running on the same host on the same UDP port then they will
|
|
# both receive all UDP search requests sent as broadcasts, but will unfortunately (due to
|
|
# what I consider to be a real weakness of most IP kernel implementations) only one
|
|
# of the servers will typically receive UDP search requests sent to unicast addresses (i.e.
|
|
# a specific host's ip address).
