Are you running a firewall (e.g. iptables) on your Linux system? If so, try turning it off and see if that fixes the problem.
Also, at the IOC prompt type the command
dbl
to make sure that you really do have a record called calc:a.

Subject: stumbled at the first softioc example
Hi all,
I’m new to the epics world. I setup epics by this article<https://pubweb.bnl.gov/~mdavidsaver/epics-doc/epics-starting.html#_softioc>.
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!
