Hi Till

Liked your talk, thanks!

Is there public access to your git repo: ~strauman/epics/caxy/, and if so, what's the missing path on the URL?.

Thanks

Peter

I have a presentation at the upcoming EPICS meeting discussing
tunneling CA via ssh. This also includes CSS.

However, rather then using EPICS_CA_NAME_SERVERS and having
to define tunnels for all IOCs I want to use (and they are *many* in
our case) I use a SOCKS proxyfier and a small program which
proxies the UDP aspects of CA so that I can tunnel name search
requests and beacons.

Currently using CSS on a remote session over the Net with NX, it's OK,
but a local session would be better.

CA tunnelled successfully over ssh:

(IOC:5064 port forwarded to localhost:10013)

export EPICS_CA_ADDR_LIST=localhost:10013
export EPICS_CA_AUTO_ADDR_LIST=no
export EPICS_CA_NAME_SERVERS=localhost:10013

cpsc_011_UPTIME 2012-04-09 19:02:07.116355 107057

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?.
