That isn't possible, AFAIK the firewall rules only know that some packets are being sent between some local and remote IP address+port, it doesn't know what the program is that's doing that I/O. Both Spec and caget use the CA client library which will perform identically given the same set of EPICS_CA_* environment variables.

Agreed - unless there is a firewall rule explicit to caget

It’s hard to see how a firewall could affect spec but not the shell caget command?

Try turning off the firewall on your pc

Hi, 

We have an EPICS areadetector soft IOC (AD core 3.6) running on a Debian PC for a Lambda detector. We are trying to control with spec, but spec's epics_caget commands return errors (e.g., "Not Connected"). When we run caget from the PC running spec, it works fine. 

Any suggestions? I know this is not a spec mailing list, but I figure this is the next best thing!

Thanks, 
Nino
