I do use your VM :)

Thank you for the suggestion, and indeed it was the solution to my problem!

After executing 

	su root /etc/init.d/iptables stop 

it works like a charm!

Yours truly,

Subject: Re: cannot read ioc PVs with caget

If you are using my VM, then, the problem may be to do with the firewall.  Check if you have it running.  In principle, caget should work fine, but just a day or two ago, a student came asked me the same question, which might be a firewall issue.  

You can check that with the following (try as root):

/etc/init.d/iptables status

If it’s running, then, you can turn it off by changing status to stop.
