# implementations only one of the servers will receive UDP
# messages with a single host (unicast) destination address.
#
# 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
# on UNIX with "netstat -i" or "ifconfig -a"; on vxWorks with
# ifShow; and on windows with ipconfig.
#
# 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 a common
# 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).
