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
