But on running css from the same shell session with the same exported
variables, it's unable to see the PV
=> Is it possible to view a tunneled PV from CSS?.
Does your CSS have JCA configured to use the Pure Java implementation of the
CA client code, or the JNI implementation that calls OS-specific? You can
find that under Preferences => CSS Core => EPICS.
I suspect the pure Java implementation of JCA doesn't have the ability to make
TCP-only connections (added to Base in 3.14.12) which is required to tunnel CA
over ssh. It should be possible to fix that by switching to JNI as long as the
native libraries it uses are from Base-3.14.12 or later. Unfortunately I also
suspect the CSS distributions have not updated those Base libraries recently,
so you might have some difficulties with this unless you build your own
You're correct, pure Java, with properties supplied by Kay, didn't work.
Using base 3.4.12, switched to JNI .. seems to pick up
EPICS_CA_ADDR_LIST etc - Nice, but still doesn't work.
Here's a clue ..
