Experimental Physics and
Industrial Control System

Hi all,

I’m new to the epics world. I setup epics by this article.
But I didn’t get pv successful. After some search, I still don’t know why.

In the article, it set the env

export EPICS_CA_AUTO_ADDR_LIST=NO

export EPICS_CA_ADDR_LIST=localhost

After start softIoc program, I use caget calc:a, cannot get anything

  Channel connect timed out: 'calc:a' not found.

And I also use the following command to make sure caget works, it seems OK.

 $ sudo tcpdump -i lo  -n -nn udp dst portrange 5064-5065
  02:32:13.408675 IP 127.0.0.1.52067 > 127.0.0.1.5064: UDP, length 40
  02:32:13.441478 IP 127.0.0.1.52067 > 127.0.0.1.5064: UDP, length 40
  02:32:13.505696 IP 127.0.0.1.52067 > 127.0.0.1.5064: UDP, length 40
  02:32:13.632719 IP 127.0.0.1.52067 > 127.0.0.1.5064: UDP, length 40

So, I suspect the softIoc don’t listen the 5064 port.

  netstat -a | grep softIoc

but I find nothing.

What I can do now?

Thanks!
