Adding SOCKS support to caj is an almost trivial patch. With that you
can tunnel CSS just fine (did you see the respective paragraphs?

Till,

I've looked over your "caxy" package.  Nice job!

Also see http://www.delegate.org/delegate/, which is a very nice "Swiss
Army Knife" of tunnelling and port forwarding using SOCKS. It does both TCP
and UDP forwarding.  The documentation is a fair translation from Japanese,
so takes a little bit of work to understand.

Less versatile is https://github.com/apenwarr/sshuttle, which uses ssh
forwarding.

Unfortunately, I was hoping for a bundled solution, so I wouldn't have to put
our users through any more work than necessary.  It's to bad that CSS is not
ssh tunnelling compatible while EPICS base, and the clients that use it, are.

Kay,

Several years ago Andre Charbonneau described how to tunnel CA
through ssh tunnels:

http://www.aps.anl.gov/epics/tech-talk/2013/msg00142.php

The method works well for EPICS base and extensions that use the EPICS
libraries.  It doesn't work with CSS because CSS doesn't use those libraries.
I think CSS uses Java CA.  I've searched the CSS documentation and the
Internet in vain.  Can it be done in the current version of CSS (4.1.1)?
If so, how?  If not, would you consider adding that functionality?
