Dear all,
    I have one OPI with base3.14.9-prel on Red Hat 9, and one IOC with base3.14.9-prel on Red Hat
 Enterprise Linux WS 4. The IP of the IOC I set is 192.168.1.1, and the OPI is 192.168.1.2.
 after "ping" and "ifconfig", on IOC it gets:

[root@localhost ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0B:DB:C2:96:D8
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0
          RX bytes:1978328 (1.8 MiB)  TX bytes:1978328 (1.8 MiB)

on OPI it gets:
[root@localhost root]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:11:09:08:A1:1E
          inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0
          RX bytes:757526 (739.7 Kb)  TX bytes:757526 (739.7 Kb)
   I set the Environment Variables EPICS_CA_ADDR_LIST=192.168.1.2 and EPICS_CA_AUTO_ADDR_LIST=NO
on the IOC. when running the IOC , the IOC can't work correctly ,it gets:
 
epics>../online_notify.c:CA beacon (send to "192.168.1.255:5065")error was "Connection refused"
  
  Then I set EPICS_CA_ADDR_LIST=192.168.1.1 and EPICS_CA_AUTO_ADDR_LIST=NO
on the OPI. After rebooting the IOC, there is no error message, but the MEDM screen go white. running
casr 10 on IOC, it gets:

epics> casr 10
