Hi Kay,

I wanted to thank you for your help. After you pointed me to the hostname issue I was able to get it up and running. Looks like I didn't define a hostname in /etc/rc.conf. Once I did and added it to /etc/hosts I am now able to read the values back with no issues. Once again thanks for the help.

Cheers,

Adam Gluck | Applications Engineer | National Instruments

Well, at least we narrowed it down to a basic network issue totally outside
of CSS, so I won't be able to help you at all.

Again, no idea why the CAJ library tries to resolve 'EPICSlinux' when all
you do is use 127.0.0.1.
Maybe it's because of channel access security. The client library is trying
to send the user and host name. So it looks for what-is-my-host-name?

On the command line, do

 hostname
 host 127.0.0.1
 host EPICSlinux

all report something meaningful?
