If you don't want to have to list all your IOCs as name servers and but
take advantage of
the UDP parts of the CA protocol (or if you use an older version of
EPICS base) then
you can use the CA-proxy which tunnels CA/UDP via ssh, too:

Greetings everyone,
I'm trying to do something rather simple but can't seem to get it to work.
What I'm trying to do is the have my CA client to connect a CA server
via a SSH tunnel. The CA client is running on a Windows system, and the
SSH tunnel is created using Putty.
Creating the SSH tunnel for port 5064 between the server and client,
using PUTTY, seems to work fine.
Then I set my Windows environment to have the following (as documented
at http://www.aps.anl.gov/epics/base/R3-14/12-docs/CAref.html#Environmen):
EPICS_CA_NAME_SERVERS=<localhost_ip_address>:5064
EPICS_CA_ADDR_LIST=
EPICS_CA_AUTO_ADDR_LIST=NO
Then when I try to access one of my PVs using the CA client, I get the
following error message:
C:\program files\EPICS Windows Tools>caget motorController:TestBox_1:C1
CA.Client.Exception...............................................
Warning: "Empty PV search address list"
Source File: ..\udpiiu.cpp line 359
Current Time: Fri Jan 25 2013 16:30:15.057180376
..................................................................
Channel connect timed out: 'motorController:TestBox_1:C1' not found.
At this point I'm not sure if any traffic is actually going through the
SSH tunnel or not. :-|
Is a second tunnel for port 5065 also required?
Anyone managed to get a similar setup working?
Any information about this would be much appreciated.
Thanks,
Andre
