Re: stumbled at the first softioc example

Thanks for reading and reply ;-)

Based on @Michael Davidsaver ‘s advice, I find the solution.
I didn’t see iocRun: All initialization complete, so I just use iocInit
command in the prompt, all works fine.
I checked the sum-start.cmd again, and find I write file like this

epicsEnvSet("ARCH","linux-x86_64")
epicsEnvSet("IOC","mytestioc")
dbLoadRecords("sum.db","INST=calc")
iocInit

when I add 1 line at the bottom, all works fine.

I guess, maybe the problem is evoked by the newline problem(\r\n, \n thing),
or it just need a new line in that cmd file.
I don’t go deep into this problem, but record here for others who encounter the same
problem.

Btw, thanks for @Kasemir, Kay, he point out that I should use netstat
like this, because it only output the port number.

netstat -an | grep 5064

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!
